Alternative fuel for the home. Common reasons for switching to alternative heating

One of the main items of expenditure of the family budget is payment communal heating or the purchase of fuel to heat the house. Every reasonable owner probably thinks about real and effective ways reducing these costs. But you can literally reduce them to a minimum using alternative energy sources. What are they and how are they used? Agree, it's worth knowing.

You will learn everything about how to arrange alternative heating for a private house from our article. With our help, you can easily decide on the most suitable option for you. A detailed description of the principles of operation of green energy schemes will provide an opportunity to decide how technological way better to use for heat.

The article describes in detail the types of sources of free energy, provides methods for generating heat for use in everyday life. To help independent home craftsmen and zealous owners of country estates, photo collections, diagrams and very useful video instructions are attached.

Traditional heat sources that have been used for heating for many years can be abandoned. Surprising as it may seem, it is very real. Many ardent opponents argue that it is impossible to replace natural resources with environmentally friendly counterparts.

The alternative is the energy of the sun, the power of the wind, the heat hidden in the bowels of the earth, the waste of production and human life. Such options are relevant in the modern world, given the general pollution environment.

Alternative sources are able to provide a country house with electricity and thermal energy

Another significant advantage is tangible savings when using environmentally friendly sources of spontaneously renewable energy. At first glance, it seems that it is unreasonably expensive and unlikely to pay off.

Having dealt with the features of each method in more detail, you can see that the eco-project pays off in 4-7 years, and then only the current costs of maintaining the used mechanisms in working order remain.

The possibility of a complete replacement of conventional fuel with alternative fuel has been proven by more than one a real example. Homeowners in different countries of the world are resorting to ecological heating options. In our country, only a few decide to radically change the usual fuel, which is becoming more expensive every year.

The main problem with the use of eco-fuels is a significant investment at the initial stage. After all, you first need to calculate in detail the amount of energy needed for a particular house or cottage. Then find out what type of eco-resource is the most beneficial in a particular area.

If all these issues are dealt with by the relevant specialists, then the final cost of eco-heating will be very high. To save money, you can try to do it on your own.

To do this, you have to immerse yourself in the topic of alternative energy sources in order to refuse to attract outside help. In this case, the cost of the project will be several times cheaper.

It is the second option that many owners of private houses choose. Their practice proves that it is quite possible to become energy independent. It is possible to completely or partially replace traditional fuel - it all depends on the size of the household, financial capabilities at the initial stage, and the chosen heating option.

The scope of "green energy" will be demonstrated by a photo selection:

Types of renewable sources for heating

To heat the house, you can successfully use the energy of wind, sun, earth. Also biofuels. Let's take a closer look at exactly how to do this and what is required for this.

View # 1 - wind power

Very successful as an alternative heating source country house wind energy can be used. This resource cannot be exhausted. It has the ability to renew itself. To use the power of the wind, you need a special device called a windmill.

The principle of using wind energy

To convert the force of the wind into an alternative source of heating, a wind generator is required. They are vertical and horizontal depending on the axis of rotation. There are many manufacturers offering their models to customers.

Wind turbines come with horizontal and vertical axis of rotation. Great performance for horizontally oriented

The cost depends on the material, the size of the installation itself and the power. You can also build wind generator on their own, using materials at hand.

Any windmill consists of the following components:

  • blades;
  • masts;
  • weather vane to catch the direction of the wind;
  • generator;
  • controller
  • rechargeable batteries;
  • inverter.

Principle of operation wind power plant is based on the force of the wind that rotates the blades of a windmill. The blades attached to the mast are high above the ground. The higher, the higher the performance. So, to supply one house, a height of 25 m is enough.

Rotating blades drive the generator rotor. It begins to produce three-phase alternating current, requiring further modification. This current is supplied to the controller, where it is converted to direct current. It is used to charge batteries.

After passing through the batteries, the current levels off and enters the inverter, where it is converted into a single-phase alternating current with a frequency of 50 Hz and a voltage of 220 volts. Now it can be used for domestic needs, in the electric heating system.

Image gallery

Features of the location of windmills

Wind turbines are capable of operating under certain conditions. Firstly, a wind generator is a rather voluminous structure that requires an impressive area for the device. A small appliance is not able to meet the energy needs.

Its height must be at least 10 m higher than the surrounding houses, trees and other buildings, and power lines and other objects must be located 100 m from the windmill. This requirement is not always feasible - not all owners of private houses have household plots of sufficient area.

Windmills are best placed on a hill, away from trees and buildings - at least 100 meters away

Secondly, it is good when the area under consideration has good wind potential - a hill or steppe zone. To start the generator, a wind speed of 2 m / s is required.

Many models of wind systems designed for use by private households are able to fully cover electricity needs.

So, a 1.5 kW windmill can generate 100-200 kWh per month, depending on the season. If the mast height is increased, then the productivity will become 2 times more.

But this will require additional costs for installation and consumables. Life time wind farms averages 20 years.

We also have other materials on the site on the device, types of wind turbines, calculation and DIY manufacturing, and installation.

We invite you to familiarize yourself with them:

View #2 - Earth Energy

One of the alternative heating systems is geothermal. It is based on the use of the energy of the Earth. This is the heat of the earth, groundwater, ambient air, converted by heat pumps (HP). It is important that the medium temperature used by the installation is above zero.

The device and principle of operation of the heat pump

For work geothermal system electricity is needed to transfer the received heat. The heat pump, using 1 kW, produces from 2 to 6 kW of heat.

The basic principle of operation of the HP is to collect heat, convert it and further transfer it to the heating circuit. This is realized thanks to the device itself.

The cheapest way to install an air-to-air heat pump. If you build it yourself, you will need a minimum financial investment

TN consists of 3 closed loops involved in the process of obtaining heat for heating a private house:

  • external - designed to take heat from sources. Antifreeze or brine circulates along the circuit;
  • internal - filled with refrigerant, more often freon;
  • heating circuit filled with coolant.

The freon filling the internal circuit is heated by the heat coming from the external circuit. Having a low boiling point, it turns into a gas in the first heat exchanger - the evaporator.

Then it enters the compressor, where it is compressed, as a result of which a lot of heat is released, and the temperature of the gas itself rises many times - up to 65 degrees.

Next, gaseous freon enters the next heat exchanger, called a condenser, where it leaves its heat. Freon, parting with for the most part heat enters under pressure on the relief valve. Here the pressure drops sharply, the refrigerant cools and, having taken liquid state, again enters the evaporator.

The heat left by the freon in the condenser heats the fluid circulating in the home's heating system. If this system provides for the installation of underfloor heating, then it is possible to achieve the most efficient heating at minimal cost.

Making the simplest version of a heat pump is easy with my own hands. This will require virtually junk parts, cheaply purchased equipment and, of course, patience. We give a diagram of a thermal system with the intake of heat energy in a well buried in dolomite.

AT constructive device Heat pumps have a lot in common. Traditional components: 1 - compressor; 2 - capacitor; 3 - evaporator; 4 - TRV, i.e. thermostatic valve

The evaporator of the system considered in the example is connected to a well that takes energy from the soil.

The photo gallery presents the specifics of a heat pump device for an underfloor heating system:

Image gallery

Feasibility of using TN

Heat pumps - HP, taking heat from the environment, are different. It all depends on the type of environment used as a source of heat intake and the type of coolant used.

Accordingly, the following types of TN are distinguished:

  • air-to-air;
  • water-air;
  • water-water;
  • ground-water.

The first two types of pumps are used in systems air heating, and the second two types - in systems with a liquid heat carrier.

The vertical version of the heat pump is the most efficient in obtaining energy from the earth, but it is the most expensive.

The most profitable from an economic point of view will be the use of thermal. This option is advisable to use if there is a non-freezing reservoir near the house, in which pipes for heat intake are laid.

The heat pump allows you to get 30 W of heat from 1 m of pipeline. Depending on the size of the private household and the energy needs, an appropriate number of pipes will need to be laid.

Air pumps will not replace conventional heating in harsh climates. As for the heat drawn from the ground, this is a very expensive project. use horizontal device geothermal field, vertical and cluster drilling.

In the horizontal version, it is necessary to build a geothermal field to a depth greater than the level of freezing. This is about 1.5-2 m. The area of ​​\u200b\u200bsuch a field is impressive - from 200 m 2.

HPs are able to replace the usual fuel in the heating system, providing complete energy independence for a country house

The implementation of the vertical and cluster project will require drilling to a considerable depth using drilling rigs.

This is a very expensive service. The equipment of this type of heat pumps is advisable for owners of cottages who do not think about the cost of work. Heating, using heat from the bowels of the earth, can completely replace solid fuel or gas.

Geothermal heating is most advantageous to use in tandem with a water "warm floor" device. It allows you to get the best result.

Among the significant disadvantages are the large length of the pipeline for collecting heat, expensive excavation for the installation of the system, the need for a large area for arranging a geothermal field.

View #3 - solar energy

Solar energy emitted by the sun all year round, capable of becoming an alternative type for heating a country dwelling even in severe frosts. It is important to learn how to properly assemble it and use it in the heating system.

To collect and convert solar energy, solar panels are used on photoelectric converters and collectors, which are a system of tubes filled with a coolant.

Solar installations have a high efficiency. Many zealous owners independently equip their homes with such systems.

The fundamental difference between these converters is that the batteries generate a current that can be used when electric heating country house. Collectors are used in the system of water and air heating. Most effective option- equipment in the premises of the underfloor heating system.

The opinion that the sun is not able to cope with the heating of the house is true only in case of incorrect installation and erroneous calculations of the amount of energy and heat needed. An optimally selected solar plant is quite capable of providing autonomous heating.

Another question is that this will require investing in the purchase of equipment, its installation and integration into the existing heating system.

Image gallery

The solar system on photovoltaic converters absorbs solar energy, and silicon photocells immediately turn it into a direct electric current. 1 m 2 of installation is capable of generating 120 watts.

In addition to panels that capture solar radiation and convert it, for solar system heating, you will have to install a charge controller, a DC-to-AC converter and take care of safety - put fuses.

Before you decide on the installation of solar installations, you need to understand their device and the principle of operation.

The advantage of the panels is the ability to connect batteries that accumulate excess energy that can be used at night. A significant drawback when using solar batteries is their greatest efficiency in the southern regions. In harsh climates, it is not economically feasible to install them for use as the main type of heating.

Solar installations equipped with a tube system are more suitable for regions with cold winters and negative temperatures. Depending on the structure of the panel and materials, there are vacuum collectors, flat and concentrators.

The most expensive among them are those with vacuum tubes. But they are the most effective at any time of the year and any weather, because they can absorb a wide range of solar radiation. Another advantage is that vacuum panels successfully operate at negative temperatures down to -35 °C.

You can install solar collectors with your own hands, without using the services of organizations specializing in this. Such work will require an assistant, but will save the family budget.

The principle of operation of the collector is that it captures solar radiation, which is converted into heat in vacuum tubes. Then it is transferred to the coolant, which delivers it to the heat exchange tank. Then the coolant enters the heating system.

In details best designs for solar heating at home we reviewed in .

View #4 - Biofuel

One of the most effective and available ways a country house is heated by a boiler that runs on biologically clean fuel.

This type of alternative heating uses production waste for its work - crop husks, wood chips, sawdust and other by-products of the woodworking industry.

There are many boilers that work on pellets. It is possible to automate the fuel supply process so that everything happens without the participation of the owner

Dense compressed granules are made from various waste small size- pellets that are burned in boilers. Compared with ordinary firewood such fuel burns longer and allows you to get more heat.

They also make large dense briquettes from various kinds of waste. plant origin. Such compressed fuel makes it possible to obtain 2-4 times more thermal energy. Its calorific value is up to 5.0 kWh/kg.

Pellets, unlike briquettes, are much smaller. They are used in an automated heating system. Briquettes are more efficient, but have a larger size

For gas boiler biogas can be used. It is easy to obtain in the process of decay of organic waste. To do this, it will be necessary to build a sufficiently voluminous tank, place waste in it, and provide an installation for mixing them.

Under the influence of air and bacteria, the process of decay and gas release will occur. A pipeline for the discharge of waste material is to be installed. Also, to collect gas in special tanks, clean it and move it to the heating system, you need to use the appropriate devices.

An environmentally friendly heating method using an alternative heat source - a hydrogen boiler.

Its work is based on the reaction of the interaction of hydrogen molecules with oxygen, during which a huge amount of heat is released. This type of heating requires compliance with the rules of operation and safety.

The principle of operation of a hydrogen boiler is based on the chemical splitting of water into hydrogen and oxygen, as a result of which a lot of heat is released and no harmful substances. But you need to follow the safety rules.

The main disadvantage is the high cost of factory equipment. The way out of this situation is to equip a hydrogen heating system on your own.

For its operation, a permanent connection to sources of electricity and water, a hydrogen burner, hydrogen generator, catalysts and the boiler itself. The resulting heat chemical reaction, enters the heat exchanger, and as a waste - plain water.

How to save on the introduction of "green energy"?

After analyzing the financial component of alternative types of heating, we can come to a disappointing conclusion - significant funds will be required at the initial stage.

Now, after 3-7 years, depending on the chosen heating method, significant savings will become noticeable thanks to a non-volatile system.

It is profitable and convenient to use a combined source of alternative heating. To do this, you can choose the most optimal combination for your home.

Save on usage and installation alternative installations to generate heat is possible. Many home craftsmen are very enthusiastic about creating analogues of factory-made alternative energy conversion devices with their own hands.

So, it is quite simple and inexpensive to assemble a solar plant from a hose, which will serve as an additional source of water heating.

Small windmills are successfully assembled at home from improvised means. Also well-read farmers living in countryside, construct installations for the conversion of biological waste of plant and animal origin into biogas.

Homemade wind turbines are quite efficient. But for their assembly, you will need to make preliminary calculations, purchase consumables, spend your time

In the future, it is used for the needs of the economy. Depending on the size of the digestion tank and the size of the private house, it is possible to fully supply the farm with biogas to meet all needs.

It is quite possible to refuse traditional sources of heating. To do this, you need to carefully select an alternative or combine several, based on the characteristics of the area, the area of ​​​​your country house and the local area.

The energy of the sun, the earth, the power of the wind, the disposal of household waste of plant and animal origin are quite capable of becoming worthy replacement gas, coal, firewood and paid electricity.

Are you using one of the alternative energy sources for home use? Share how much it cost you to assemble the unit and how quickly it paid off.

Or maybe one of your friends has equipped his country house on renewable sources? Using a solar panel system or a heat pump as an independent source for heat, hot water and electricity?

Tell us about this experience in the comments below the article - a good example will be useful for homeowners who still doubt the reality of alternative energy.

Alternative heating should be understood as systems that use free natural resources for their work. Among the most popular options for such systems are installations operating using solar and wind energy. On the device of such heating, other things being equal, you will have to spend less money than on the construction of more familiar heating communications, and in terms of operating costs, alternative heating is in the undoubted leaders.

Back in the middle of the last century, people learned to use wind energy to generate electricity. The systems under consideration are based on wind turbines. A typical windmill consists of several blades and is connected to the generator directly or through a gearbox.

There are rotary, high-speed and low-speed models of wind turbines.

  1. Slow windmills equipped with a large number of blades, they practically do not make noise during operation, but are relatively inefficient.
  2. Design high-speed wind generator usually includes 3-4 blades. Such an installation is designed for wind speeds of 10-15 m/s. High-speed windmills are quite noisy, but have a high efficiency, for which they are most widely used in the world.
  3. The rotary windmill looks like a kind of barrel. Blades are installed vertically. The advantage of such a wind generator is that it does not need to be oriented in the direction of the wind. Rotary models are characterized by the lowest noise and, at the same time, the most modest efficiency. warm up private house using a rotary windmill is extremely problematic.

It is the Sun that is currently considered as the most promising source of alternative energy. On average, for a year, the star closest to our planet gives off 30-35 thousand more heat than the entire population of the Earth consumes.

World scientists lead continuous work on increasing the efficiency of various solar installations and photoelectric converters.

At home, you can assemble the mentioned installations and use them to heat water, i.e. building water heating on alternative energy is quite realistic. However, the performance of home-made installations rarely reaches even 50% of the performance of full-fledged factory-made units. Therefore, it is better to buy ready-made solar panels and all related elements, and already assemble and install them yourself.

Remarkably, industrial units allow you to get warm water even in frosty weather. All you need is for the sun to shine.

There are solar plants for indirect and direct heating.

  1. Greenhouses and water boilers installed outdoors are examples of direct heating facilities. Even the glazed veranda is a kind of direct heating solar plant. However, the situation is overshadowed by the fact that heat is spent irrationally.
  2. Indirect heating, on the other hand, gives the user the opportunity to install the unit for receiving solar energy where it will be most convenient, for example, on the roof. The functions of the coolant in such systems are usually performed by special non-freezing liquids. Heat is transferred from the water storage warm water climbs on household needs user, its place is taken by cold liquid and the cycle repeats.

Also, solar plants are classified into flat and tubular.

  1. The first type has the form of a box with a spiral heating element, usually made of copper. On three sides, such a spiral is thermally insulated, while on the sunny side it is covered with glass. Flat installations no problem assembled by hand. This is a budget and easy to use option, but the efficiency flat installations leave much to be desired. The functions of the coolant in the system under consideration are usually performed by antifreeze liquid water can also be used.
  2. Tubular blocks are assembled from several tubes up to 400 cm high. The tubes are placed parallel to each other. The system can consist of any required number of tubes. The function of the coolant in such a system is performed by a special liquid with a low boiling point, due to which it is possible to significantly increase the efficiency of the unit. Compared to flat solar systems, tubular solar systems are approximately 30-40% more efficient.
    It is possible to increase the productivity of the installation under consideration by including a special pump, heat exchangers and thermally insulated pipes in the system. The panel is installed at an angle, usually 30 degrees.

Tubular installations are great for heating water and can take an active part in heating the house.

Installation for solar heating at home

At the heart of the solar heating system of the house will be an elementary collector, which can be assembled with your own hands from improvised means.

First step. Remove the coil from the refrigerator and rinse it thoroughly clean water. It is important to remove all old freon from the coil.

Second step. Assemble the frame from wooden slats. Frame dimensions are selected individually in accordance with the dimensions of the coil. It is necessary that the coil fits between the rails without any extra effort.

Third step. Apply markup. Attach the coil to the rack frame and mark where the pipes will exit.

Fourth step. Install the bottom frame rail. Between finished frame and a sheet of foil should be laid with a rug.

Fifth step. Increase the rigidity of the system. To do this, fill the slats on back wall designs.

Sixth step. Glue the gaps between the previously laid foil and the base of the unit with adhesive tape. Such sealing will not allow cold outside air go inside the system.

Seventh step. Install supply pipes. Simple plastic water pipes are perfect for connecting water.

Eighth step. Seal the joints of the coil and plastic pipes with the same tape.

Ninth step. Finally fix the coil to the body. For fixing, you can use clamps from the same old refrigerator. Additionally, the product should be fixed with screws.

Tenth step. Cover the system with glass and glue it with tape around the entire perimeter.

solar collector

On this assembly work solar collector may be considered completed. It remains only to fix the supports so that the rays of the sun fall on the plane of the collector at a right angle. Additionally, a few screws need to be fixed at the bottom of the frame. They will not allow the glass to move out when heated.

A homemade collector is connected to storage capacity with water. The tank is connected to water pipes and / or heating pipes. To increase the efficiency of the system, the system is equipped with a pump.

Assembly and connection of the wind generator

Wind is the second most popular source of alternative energy. Homemade wind turbines allow you to provide the house with heat at minimal cost.

First stage. Select the appropriate type of structure and its power. Beginners are advised to opt for the most popular vertical wind turbines. Select power individually. Increasing the power of the wind generator is carried out by increasing the size of the impeller and adding additional blades.

However, remember that the more powerful the device, the more difficult it will be to balance it. The best option for self-manufacturing is a windmill with an impeller with a diameter of about 2 m and 4-6 blades.

Second phase. Make a foundation for the wind turbine. An elementary three-point base is enough. Determine the depth and area of ​​the structure individually, taking into account the characteristics of the soil and the climate at the construction site.

Install the mast not earlier than the complete solidification of the base, i.e. in about 1.5-2 weeks. Instead of a foundation, you can use stretch marks. This is an even simpler option for installing a mast. Dig a small pit with a depth of about 50-60 cm, install a wind turbine mast in it and securely fix the structure with ordinary stretch marks.

Third stage. Make the blades. Perfect for this at home. metal barrel. You need to divide the container into identical parts in an amount equal to the number of selected blades. Mark the blades first, it is important that the blades are exactly the same size. Cut out the blades of the future wind generator. The Bulgarian will help you with this. In the absence of a grinder, you can get by with scissors for cutting metal.

Fourth stage. Fix the workpiece on the generator with bolts, and then bend the blades. Many parameters of the wind generator operation depend on how much the blades are bent. No specific recommendations can be made in this regard. Define suitable angle you can only experience.

Fifth stage. Connect the electrical wires to the generator and connect the elements of the system into a circuit. Fix the generator on the mast of the windmill, then connect the wires to the mast and turn on the generator and battery in the circuit. Give the load with wires. At this wind generator is ready. You can connect it to the water heating system through the same storage tanks.

If you wish, you can assemble and install several windmills if one device is not enough to fully provide the house with heat.

Thus, the use of alternative energy is a very promising direction that definitely deserves attention. Now you can feel like a part modern world and significantly save on heating by assembling a simple wind or solar installation. Follow the instructions and you'll be fine.

Successful work!

Video - Do-it-yourself alternative home heating

The development of a house project involves solving the issue of creating a rational and efficient heating system. All more developers tend to use non-traditional methods to heat their homes.

Warmth and comfort in the house - the task of competent heating

The implementation of alternative heating in a private house is a feasible task, since there are a number of modern technologies.

High-tech equipment makes it possible to extract energy from renewable sources. Its use provides, in addition to warmth and comfort in the house, significant savings on the purchase of energy resources.

Alternative methods of heating are considered to be, in addition to the use of renewable sources, innovative technologies using electricity.

What is alternative heating?

Probably, there is no such person who would not have heard about the existence of alternative heating. However, when classifying one or another type of energy production in an unconventional way there is some confusion. They mistakenly believe that the use of infrared radiation, biofuels, geothermal energy and a number of others are all alternative energy sources. Therefore, when determining alternative methods energy sources, it would be correct to consider those for which the consumer does not pay the energy supplier and at the same time the costs of obtaining it are at an acceptable level.

Why is this needed?

Solar panels

The main reason for the use of alternative heating systems in private homes is the desire to achieve maximum cost savings and the creation of an autonomous energy supply. This is due to the trend of constant growth in energy prices and the inevitable depletion of natural resources.

In addition, true love for the environment, the desire to save it are one of the motivating motives for the transition to alternative forms of energy. One way or another, the process of extracting minerals from the bowels of the earth and their processing lead to pollution of the Earth.

Alternative heating options

Each of the alternative heating technologies used to heat a private house has its own characteristics and specifics. When choosing it, one should understand the task that the equipment must solve, and the specific conditions of its operation. The correct selection of the heating method will allow you to completely abandon traditional energy, and the owner of the house will receive the expected economic effect.

solar systems

Solar energy can be used to heat a home in the following ways:

  • Transformation into electrical energy, which is later required for the operation of heaters.
  • Use directly for heating the coolant, which naturally or with the help of a pump enters radiators or convectors.
Solar energy for heating

The simplest method of alternative heating is the creation, perhaps with your own hands, of a heating manifold, pump and radiator in a private house.

You can implement solar heating in the following ways:

Wind energy

Design and principle of operation

The wind generator is a structure mounted on a rod, which is equipped with blades that can rotate. They are divided according to the location of the axis of rotation into vertical and horizontal. By design, the first of them can be rotary or bladed, the second - winged.


wind generator

The composition of the windmill includes the following elements: a turbine, which is driven by blades or a rotor, electric generator, battery, controller and inverter.

The operation of such a device is quite simple and consists in the following: wind flows cause the blades to rotate, which is transmitted to the generator. When rotating, the generator generates electricity, which is stored in batteries. With the help of the converter, the required voltage is created.


Wind energy for heating

Electricity generation using windmills is expedient on an industrial scale, since the equipment has a significant cost. It is quite enough to install one wind generator for heating the house. Batteries are connected to heating elements heating system and DHW.

Advantages and disadvantages

The advantages of such heating include the following factors:

  • renewable energy source;
  • environmental cleanliness of energy production;
  • relatively low cost electrical energy;
  • safety of the energy generation process;
  • installation of windmills solves the problem of obtaining energy in hard-to-reach places.

The disadvantages of obtaining energy using wind turbines are:

  • the payback rate of equipment increases with an increase in the number of devices;
  • a significant area is required to create wind farms;
  • it is possible to implement the process in a windy area;
  • significant cost of equipment;
  • noise at work.

Heat pumps

Each of us daily uses a unit that works on the principle of a heat pump, but not everyone knows about it. We are talking about a refrigerator, however, its functions are different. It is impossible not to notice the fact that in addition to cold, heating occurs with back side. During the operation of the heat pump, similar processes occur, while the heat is used to heat the house.


Heat pump

Contemporary heating equipment, whose operation is based on the principle of a heat pump, allow the extraction of thermal energy from various natural sources. Soil or water are more efficient energy sources than air.

How a heat pump works

Liquid with positive value temperature (even minimal) passes through the evaporator, in which its temperature decreases. Thermal energy, selected in this way, is transferred to a compressor that compresses the liquid. At the same time, its temperature increases. Then the liquid moves to the heat exchanger, where its temperature decreases, and the energy received is transferred to the heating system or hot water circuit. After that, the cooled liquid moves to the evaporator, and the cycle repeats.

Heating system device with heat pump

Heating of a private house, organized on the basis of heat pump technology, consists of the following main elements:

  • Probe. The design is a branched pipeline system, which is a large coil, placed in a certain environment: water, soil or air. The function of the probe is to take energy from a particular medium and transfer it to the heat pump.
  • Heat pump.
  • Heating system. The main part of this device is a heat exchanger. The efficiency of the entire system mainly depends on its operation, that is, on the ability to transfer heat from one medium to another.

Heat pump circuit

ground water

The universality of this method of obtaining energy lies in terms of choosing a region for its implementation. The temperature of the soil located at depth is in any case above the freezing point of water. Achieving the required temperature difference can be achieved in different climatic zones at different depths.


ground water

Heat is taken in when the probe-heat exchanger is immersed in the well. It should be understood that the cost of drilling, installation pumping equipment and its acquisition significantly increase the cost of implementing a heating project.

In order to reduce the cost of heating a house in a ground-water system, they resort to laying a heat exchanger in a horizontal plane. However, this requires a significant amount of space. Laying in this case is carried out at a depth exceeding the level of soil freezing.

water-water

If there is groundwater in the area where the house is located, lying at high horizons, the cost of heating the house with a heat pump is significantly reduced.


Energy from water

Energy is easier to extract from running water. In this case, it is sufficient to use one heat exchanger probe.

Also, drilling a well to a significant depth will not be required, it will be possible to stop at 10-15 meters.

Air to water

Fan

During the operation of the air-water system, the energy source is atmospheric air. In this case, the radiator is a heat exchanger with a large fin area. It is blown by a low-speed fan.

The cost of equipment and its installation is significantly lower than when using a water-water system. A decrease in air temperature leads to a decrease in its efficiency, since it makes it difficult to extract energy.

Air to air

The cheapest alternative way to generate heat is an air-to-air heat pump. A split system operating in heating mode is an example of this.

In this case, electricity is not spent on heating the air, but is spent on maintaining the operation of the compressor. This achieves an economic effect when compared with the operation of a traditional air heating device.


Air-to-air system

Advantages and disadvantages of using heat pumps

The use of heat pumps for home heating has several advantages:

  • the possibility of using the technology anywhere on Earth;
  • absolute environmental friendliness of energy production;
  • the versatility of the method lies in the possibility of using the equipment, if necessary, as an air conditioner;
  • sufficiently high efficiency of the heating system, provided that good thermal insulation of the premises of the house is created;
  • high safety of equipment operation.

The main disadvantage of heat pumps is the high cost of equipment and its installation.

The quality of the heating system has a direct impact on the comfort and coziness in the house. Its arrangement must be taken carefully, since you have to stay indoors for a long time, especially in winter period. In the conditions of modern life, more and more owners of their own residential real estate choose alternative ways heating of a private house. Next, let's see what they are. The article will also talk about what alternative sources there are heatings of a private house.

General information

Alternative heating should be understood as a system, the operation of which is carried out with a heat generator on a renewable energy source. Options are very different. Alternative heating sources for a private house can be mechanisms that use biofuels, wind, solar or water energy, and so on. The schemes include boilers and heat pumps. The system may include solar panels. They accumulate incoming heat and convert it into electrical energy.

Biofuel use

Such alternative heating of a private house is becoming more and more popular every day. Biofuel should be understood as a mass that includes various organic wastes, plants, manure, and effluents. During the decomposition process, in which bacteria take part, biogas is produced. Chips from wood pellets, logs, pressed waste can act as fuel. These materials are used, as a rule, in low-rise buildings. In larger facilities, the supply of biofuel is carried out using an automated system. Alternative heating a private low-rise house is carried out manually. Heating boilers working on pallets are presented in several versions. However, in all cases, fuel is supplied automatically. Thanks to this person, there is no need to constantly be at the boiler. The units have a built-in automatic control system that maintains the temperature at a certain level.

Alternative types of heating a private house: pumps

To implement this option, it is necessary to have a well from which groundwater will be taken and the waste material will be drained back into the soil. You can create an alternative type "water-water". However, the user for a small residential structure will have to dig 2-3 wells for water intake and 1-2 for draining. It is necessary to drill to a depth of at least 50 meters. For the construction of such wells, permission must also be obtained from state control services. In the scheme of such heating, heat pumps are used. To connect the alternative heating of a private house with your own hands according to the "brine-water" type, you need to dig a 200-meter well. In it, pipes with a solution should be laid in a U-shape. To reduce the difference in heat generated in different months, a heat exchanger is installed, which is located at a depth of at least five meters. Alternative heating of a private house using pumps is considered the most economical in comparison with other schemes. Such equipment is safe for both humans and the environment. This alternative heating of a private house is considered the most promising today. The installation instructions are quite simple. You can cope with the installation of the pump and laying pipes yourself.

Solar storage collectors

Such an alternative heating of a private house will be directly dependent on the intensity of the rays, which in different time year is different. In cloudy weather and at night, the radiation energy is not enough for the normal and stable operation of the collectors. Often solar panels are used as water heating elements. It can be used for household or economic needs. Heated water can participate in heat exchange in monovalent storage tanks. Solar panels can additionally be used to generate energy in biovalent units.

Collector classification

They are of two types:

  • with vacuum tube.
  • Flat.

When using the equipment in summer period the performance coefficient of both types will be the same. In winter, it is better to give preference. This equipment is able to work at -35 degrees. Flat-plate collectors can heat the air up to 60 degrees. Vacuum units are designed to increase the temperature up to 90 degrees. For other parameters, there are no differences between the devices. Vacuum is great for use in a country house as in addition, they can be used to heat water.

Wind energy

Industrial products are sold today quite freely and cost quite reasonable money. This can be used in regions where constant moderate winds prevail. First of all, it is the coast and steppes. Installing a wind turbine is no big deal. Its main structural elements are blades, motor and mast. The wind generator has a slightly reduced efficiency in comparison with the collector system. This is due to the fact that the elements of the latter can be used immediately to produce heat or heat water. And in a wind generator, you must first convert mechanical energy into electricity. Only then will the air in the room be heated.

Alternative heating of a private house with hydrogen

This fuel is used in specialized boilers. These units are capable of generating an unlimited amount of energy. At the same time, hydrogen boilers are considered completely safe, since such heating is considered flameless, and combustion products are not emitted during heating.

Process progress

The work is based on a catalytic reaction. It flows between hydrogen and oxygen. As a result, water molecules are released. During the reaction, a sufficiently large amount of heat is produced. Hydrogen boilers can simultaneously work effectively with a floor heating system.

Equipment characteristic

Hydrogen boilers are produced different power in accordance with the area of ​​\u200b\u200bthe room to be heated. The efficiency of the units is quite high. It is about 96%. The number of channels used to connect hydrogen heating depends on the tasks. You can create a maximum of six of them. Everything will depend on how much heat the boiler will need to produce. We can say that the units, in essence, are considered boiler rooms modular installations. Therefore, the available power channels can perform their tasks perfectly without being dependent on each other. In each of them there is a "catalyst". It has a significant effect on the formation of H 2 O molecules, accompanied by the process of formation of heat fluxes. They fill the combustion chamber (heat exchanger). Artificial heating is carried out up to 40 degrees. This indicator is considered acceptable for maintaining a constant optimal temperature both ceiling and floor.

Industry Development

It should be said that heating with hydrogen today is just beginning to gain momentum. As one of the undoubted advantages of the system, it should be noted that the boilers can operate as auxiliary equipment at low temperatures. Hydrogen can be considered a revolutionary type of fuel. The use of modern technologies allows you to easily adapt it to heating systems.

What is alternative heating? How does it happen, what can serve as a source of thermal energy? Is it possible to install alternative heating of a private house with your own hands?

Let's try to figure it out.

What it is

By this name, when it is used in the press, it traditionally refers to all the ways to heat housing that were not used twenty or thirty years ago. Geothermal heat sources, film underfloor heating, biofuels, and infrared heaters are thrown into a common heap.

Within the framework of the article, however, we will allow ourselves to interpret the term much more narrowly.

We are interested in alternative home heating, which:

  1. It uses renewable sources of thermal energy as heat, for which there is no need to pay sellers of the corresponding services or goods. Alternatively, at least part of the thermal energy is taken from renewable sources.
  2. Can be implemented at reasonable cost. At least - incomparable with the cost of the house itself.

Why is it needed

The reason why alternative heating systems of a private house are attracting attention is simple and understandable: rising energy prices and, accordingly, electricity. Solarium, gas, coal are steadily becoming more expensive.

Useful: main gas is now cheaper than other types of heating. But it continues to rise in price. Its reserves are limited, so the trend will continue and intensify in the coming years.

Well ... do not consider the author an idealist, but still it is barbaric to burn fossil fuels or trees to heat a small inner space your home. In this sense, alternative types of heating are not just cost-effective. They are progressive.

Implementation Options

solar systems

Solar energy is used to heat homes in two ways:

  1. By transforming into electricity, which can then be used to operate heaters.
  2. For direct heating of the coolant, natural circulation or circulation pump then run through radiators or convectors.
    The simplest do-it-yourself alternative heating is exactly (often home-made), a circulation pump and a radiator in the house.

The peculiarity of solar systems is obvious: sunny days even in the Crimea or Central Asia they are still replaced by cloudy ones. No one canceled the night either. If so, they are unsuitable as permanent heat sources.

What implementation options are possible?

  • works in parallel with the electric heater. The coolant temperature is controlled by sensors; when it falls below a certain level in cloudy weather, the heaters are heated.
  • it is supplied not only with a controller and an inverter that generates a mains voltage of +12 or +24 volts DC, but also with a high-capacity battery.
    During daylight hours, solar panels store energy in batteries; Batteries serve as a source of power at night or on cloudy days. With the appropriate area of ​​the photocells and the capacity of the batteries, it is possible to realize a completely energy-autonomous system.
    But here we are in for an unpleasant surprise: we are limited by the level of available technologies for storing electrical energy. Best Samples batteries will live in such a system for no more than five years, and the cost of replacing them will be quite comparable to the cost of electricity purchased from energy companies during this period.
  • Finally, the simplest solution that saves electrical energy (and heat) can easily be implemented by hand.
    Alternative heating of an apartment or a private house (or rather, to be precise, energy supply) in this case is a solar battery with a controller and an inverter, which is connected in parallel to any outlet, and electric heaters any type.

Nuance: you need a mechanical, disk counter. Electronic ones are not able to register the reverse direction of the current. In sunny weather, when the photovoltaic cells generate more electricity than you spend on heating, the meter simply counts down the kilowatt-hours in the opposite direction. The savings are more than tangible.

Wind energy

For the production of thermal energy, energy that is generated by a windmill can also be used.. Industrial products are sold in bulk and cost quite reasonable money.

The only obvious feature of this solution is big size impellers. At a 4-kilowatt wind generator, it reaches ten meters.

All the problems of accumulating electrical energy for heating, typical for solar systems, fully apply to wind turbines.

  • It is clear that alternative heating of a country house using wind energy can be implemented only in those regions that are characterized by constant moderate winds - primarily in the steppes and on the coasts.
  • In addition, if the collector can use solar energy directly to heat the coolant, then the transformation of the mechanical energy of the windmill rotation into electricity is inevitable here, and only then into heating the air in the room. Which, as you might guess, means a decrease in the efficiency of the system.

Heat pumps

Finally, the most versatile alternative to central heating is heat pumps.. The principle of operation of all devices of this type is the same: the transfer of thermal energy from a low-potential source to the house. Simply put, the pump takes heat from a cold object and gives it to a hot one.

This is how heat pumps of all types work. The difference between them is in the source of low-grade heat.

All heat pumps are based on the same simple system that can be seen by disassembling any refrigerator: a compressor, a heat exchanger and an evaporator. But the specific implementation can vary greatly, giving a large variation in the cost of the solution.

ground water

Ground-to-water heat pumps are the most versatile in terms of climate zone alternative sources of heating of a country house. The principle of their operation is based on the fact that even in areas of permafrost at a depth of several tens of meters, the soil temperature is consistently above zero.

Accordingly, heat exchangers that take heat from the ground are probes immersed in wells. The length of the highways is tens of meters; in addition to the high cost of the heat pump itself, the price of its installation is impressive.

The cost of drilling one well is estimated at 1500 - 2000 rubles per running meter; Several wells are being drilled. But you still need to mount the pump itself and immerse the probes ...

It is somewhat cheaper, however, to install a ground-to-water heat pump with horizontal arrangement collector. Heat exchangers are buried in trenches below the freezing level. The downside of this solution is the large area required to install the pump.

The resulting heat is used to heat water, which is used for household needs and to transfer heat to heating devices.

water-water

If at shallow depths in your area there are flowing ground water- The cost of the project for you will decrease dramatically.

It is much easier to take away the heat we need from running water:

  1. You can get by with one submersible heat exchanger probe;
  2. The drilling depth can be limited to 10-15 meters.

Air to water

AT heat pump operating according to the air-water scheme, the source of heat is the street air. Heat exchanger - a radiator with an impressive fin area; it is blown by a low-speed fan.

Such pumps have a much more democratic cost compared to the previous ones and are much cheaper to install. However, when the temperature drops outside, their efficiency also drops dramatically: it is more difficult to take away thermal energy from cold air.

The COP parameter is the ratio between consumption and heat output. You can see how it changes at temperatures from +7 to -15.

Air to air

Finally, listing alternative sources of heating at home, one cannot fail to mention the absolute champion in terms of the cheapness of the project - an air-to-air heat pump. The simplest example of such a device is a conventional split system in heating mode.

Due to the fact that electricity is not spent on heating the air, but on the operation of a compressor pumping heat from the street, heating with an air conditioner is much more economical than a conventional heater.

The best examples of inverters (using inverse conversion alternating current 5 kW of heat is pumped into the house for every kilowatt of electricity consumed and back to change the speed of the compressor) of air conditioners.

Inverters from a decent manufacturer cost up to a thousand dollars with installation and are capable of operating at outdoor temperatures down to -25C.

An inverter air conditioner is the perfect solution for a temperate climate.
