Sources and methods of alternative heating in a private house and apartment. Alternative heating of a private house - a whim or a vital necessity Alternative heating of a private house with your own hands

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. In the conditions of modern life, more and more owners of their own residential real estate are choosing alternative methods of heating a private house. Next, let's see what they are. The article will also talk about what alternative sources of heating a private house are.

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 of a private low-rise house is carried out manually. Heating boilers operating 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 alternative heating of a private house will be directly dependent on the intensity of the rays, which is different at different times of the year. 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 business 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 equipment in the summer, the performance coefficient of both types will be the same. In winter, it is better to give preference. This equipment is able to operate 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 in different capacities in accordance with the area of ​​​​the room that is supposed 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 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 optimum temperature for both the ceiling and the 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.

Alternative home heating includes all possible options that were not used 20-30 years ago. These include geothermal heat sources, biofuels, film underfloor heating, infrared heaters. In our article we will consider the minimum cost sources of heating. We will describe some sources of heating for which you do not need to pay money to utilities. Sometimes some part of thermal energy is taken from auxiliary sources.

The reason for using alternative heating is clear - it is savings. Today, energy and electricity prices are skyrocketing. Gas, solid fuel, solarium become more expensive. In the modern world, alternative heating is simply necessary, since minerals are not unlimited, and it is simply not reasonable to burn tons of wood to heat a small room.

solar systems

This device is designed to transform solar radiation energy into other forms of energy. For example, for heating and cooling water and air. To heat the coolant, a circulation pump is used, which directs heat to radiators or convectors.

Solar options

Wind energy

Humanity has been using wind energy for many years. and now in many countries they serve man. But now wind energy is mainly used to generate electricity. This type of energy is clean and environmentally friendly.

Wind, hitting the turbine blades rotates it and generates energy. The energy efficiency (COP) does not exceed 59%. Back in 1920, the scientist Betz received this value. Since that time, this value has been called the "Betz limit". Thus, if you know the conversion efficiency, you can determine the required power of the power plant.

Distinctive features of wind generators

The settings differ depending on technical characteristics of the wind turbine:

• number of blades;
• location of the axis of rotation;
• screw pitch;
• element material.

Wind generators come with vertical and horizontal axis of rotation.

A horizontal axis propeller design can be single or multiple bladed. Such wind turbines are the most common, as they have the most high efficiency.

Designs with a vertical axis are divided into orthogonal and carousel (Dariaer and Savonius rotor).

• Rotor Daria- orthogonal design, in which the aerodynamic blades are arranged symmetrically to each other and they are mounted on radial beams. This version of the wind turbine is quite complicated due to the aerodynamic design of the blades.
• - carousel-type wind turbine designs with two blades that form the shape of a sinusoid. For such structures, the efficiency not high(no more than 15%). But if the blades in the direction of the wave are placed not horizontally, but in a vertical position and the structure is made multi-tiered with an angular displacement of pairs of blades relative to each other, then the efficiency can be almost doubled.

Advantages and disadvantages of wind farms

The main advantage of "windmills" is that a person gets the opportunity to reproduce practically free electricity, not counting the small construction costs.

In order for a wind turbine to operate efficiently, constant wind currents, and it depends only on nature. The technical disadvantage is the low quality of electricity, so the system must be supplemented with auxiliary modules (chargers, batteries, stabilizers, etc.).

Horizontal-axis installations have enough high efficiency, but for stable operation, a wind flow direction controller and devices that protect against hurricane winds are needed.

Vertical-axis installations have a small efficiency, but they are sufficient compact and stable during strong winds. They work without a mechanism that allows you to follow the direction of the wind and are almost silent.

Heat pumps

Heat pumps provide home heating, hot water supply, air conditioning. This system works thanks to borrowing energy from the environment. You can accumulate heat from the ground, air and water free of charge. Working from the mains, heat pumps distribute the energy expended significantly more productively than electric, solid fuel or gas boilers. With a consumption of 1 kW of electricity, we get 4 kW of heat. So, we get 3 kW of heat for free from the environment. Such systems cost more than gas, solid fuel or electric boilers, but at the expense of free natural energy a thermal boiler pays for itself in a couple of years. The energy performance of heat pumps directly depends on the temperature of the low-grade heat source. Thus, the higher it is, the greater the savings.

Another type of heating that allows you to seriously save is air:

Fundamentals of heat pump operation

1. The coolant moves through the pipeline, which is laid, for example, into the ground, warms up 3-4 degrees. Then it passes through the heat pump and heat exchanger and transfers the heat that accumulates in the environment to the internal circuit.
2. The internal circuit is filled with refrigerant. This substance has a fairly low boiling point. The refrigerant passes through the evaporator and passes from liquid to gaseous state. This occurs under conditions of low pressure and temperature.
3. In the compressor takes place refrigerant gas compression and temperature rise
4. The hot gas then enters the condenser, where heat exchange takes place between the gas and the coolant. The refrigerant transfers its own heat to the heating system, cools down, and again becomes a liquid. After that, in heating devices heated liquid enters.
5. When the refrigerant passes through the pressure reducing valve - the pressure decreases. Further, the refrigerant passes into the evaporator, and the cycle is repeated.

Types of heat pumps

All heat pumps work on the same principle as any refrigerator, but there are differences in their implementation. According to the type of heat carrier used, heat pumps differ as follows:

The following material will help to make a heat pump at home:

Taking into account all the features of each type of alternative heating, we can come to the conclusion that with the right calculations and skillful installation, you can get an excellent heating option practically from the air, without spending natural resources.

There are many options on the modern market - ranging from solid fuel boilers for home heating to heat pumps. Most homeowners believe that it is profitable to heat the house with a gas boiler, but FORUMHOUSE users know that under certain conditions this is far from the most optimal solution.

Due to the constant rise in energy prices and the high cost of connection, many developers are concerned about the following issues.

• Is there an alternative to the main gas;
• What features can different heating systems have;
• How to calculate the price of a particular type of fuel;
• Is it profitable to use solid fuel heating systems;
• How to heat a house with electricity and not go broke;
• Can a home heat pump replace traditional heating systems.

And experts and users of our forum will help you find answers to these questions!

The main criteria for choosing a heating system

Construction experience suggests that autonomous heating of a private house is selected taking into account many factors: the degree of availability of a particular type of fuel, the estimated monthly heating costs, climatic living conditions and building heat loss.

Heating a house in a temperate climate is one task, and completely different requirements are placed on the heating system in regions with an even colder climate than in Moscow and a months-long heating season.

The efficiency of the heating system at home depends not onlyon the thermal characteristics of the fuel and the efficiency of the boiler, but also on the design features of the house and the degree of its heat loss.

A poorly insulated dwelling nullifies the work of the most highly efficient heating system!

Therefore, the choice of a heating system and boiler equipment must begin at the design stage of your future home. Any of the experienced developers will agree with the statement that there are no trifles here, and any mistake or flaw can lead to costly rework.

First of all, let's consider .

Alexander KhadynskyHead of the heating systems department of the company "My fireplace"

The choice of heating system, first of all, depends on what communications are connected to the house. If the main gas is already connected, then the choice of fuel usually ends there, because. at the moment, heating the house due to main gas is recognized as the best solution.

It is also worth considering the convenience of operating the heating system in different modes of residence: daily, weekend mode, one-time visits. Only after weighing all the pros and cons, you can choose the best option.

In the absence of main gas, the process of heating the house on the so-called gas tank is possible - a sealed container buried on the site and in need of periodic refueling.

The advantages of liquefied gas, as well as main gas, are clean exhaust, the ability to install compact chimneys and small boilers for heating poison.

With all the advantages, this system of autonomous heating of the house has a number of disadvantages.

Anatoly Gurin CEO of DoM Engineering Systems

The main disadvantages of a gas tank include: expensive installation, inconvenience of refueling, obtaining permits, and the need for periodic maintenance by highly qualified personnel. In addition, the gas tank takes up a lot of space on the site.

Igor Larin Head of "Boiler Equipment" WIRBEL

The choice of fuel, and hence the boiler equipment, depends on the degree of its availability in a particular region. If the house has main natural gas, then the choice is obvious in its favor, if not, then it is necessary to assess the cost and availability of other types of fuel for heating in the area, and install equipment accordingly.

How to replace gas

The advantages of gas are well known, but all of them are offset by the extremely high price of supplying it. Let's consider alternatives.

Liquid fuel

Diesel heating – requires the installation of expensive and complex equipment.

It is necessary to find a place to install a fuel tank. Diesel fuel has a peculiar and not for everyone pleasant smell. Also, due to the constant increase in prices for hydrocarbon fuels, heating with diesel fuel is one of the most expensive ways to heat a house. Among the main advantages for this type of home heating, a high degree of automation of the boiler and the ubiquity of diesel fuel can be distinguished.

Electricity

Electric boilers are easy to operate, environmentally friendly, safe and silent.

Alexander Khadynsky

However, with low initial costs for the purchase of equipment, it is very expensive to heat with electricity, and during power outages, you can be left without heating and without hot water. Also, an electric boiler for heating a house will need to install separate wiring, and if its power exceeds 9 kW, a three-phase network of 380 V.

In addition to electric boilers, there are such heating devices as electric convectors and infrared emitters.

The advantages of heating with electric convectors and infrared emitters include minimal initial costs and simplicity of the equipment. You do not have to deal with the arrangement of the boiler room or conduct heating pipes. It would seem that he took the device out of the box, plugged it into the network and use it. But, as practice shows, not everything is so simple.

Oleg Dunaev civil engineer

A well-insulated house can be successfully heated with an electric convector only if there is sufficient electrical power.

• high equipment efficiency;
• ease of installation;
• presentable appearance;
• safety of use;
• the ability to program energy-saving modes.

The cons include:

• additional costs for high-quality wiring;
• increased requirements for the quality of power supply elements.

Unlike an electric boiler, installing a convector or any model of an IR emitter does not require laying pipes and the presence of a heat carrier, as a result, inefficient energy costs for heating water (coolant), boiler and pipes are reduced, and heat losses are reduced.

Here are the main criteria for choosing such a heating system.

Oleg Dunaev :

- We choose this way: the power of one convector is up to 1.5 kW (more - the plugs melt and the relay contacts burn).

The programmer has its own power supply (settings are saved when the power is turned off). For 10 sq.m. area requires approximately 1 kW of convector power.

Electricity - 380V, 3 phases, permitted power - at least 15 kW. Wiring section - 3x2.5 sq. Mm. We lay dedicated converter lines and connect no more than three convectors to one line.

A wall-mounted electric convector is best hung under a window about 15 cm from the floor.

Heating with electricity is one of the most expensive ways to heat a home. It would seem that cheap heating with electricity is a myth. However, a user of our forum Alexander Fedortsov(nickname on the forum Skeptic ) refutes this assertion by its own example.

Skeptic Forumhouse User

I independently built a well-insulated frame house on the foundation of the UWB. First, according to the project for heating a house with an area of ​​186 sq.m. a solid fuel boiler was supposed. After a little thought, I decided that I didn’t want to become a stoker at all, but it was better to use the night tariff and heat water in a reliable home-made heat accumulator with a volume of 1.7 cubic meters.

Water heated overnight by electric heating elements up to 50 C, allows you to successfully heat the house in the winter months with a water heated floor system. You can monitor the temperature with a custom controller.

Alexander Fedortsov

I put the floor heating unit in the boiler room on a sheet of foam plastic of 35 density and 10 cm thick. The heat accumulator is well insulated - 20 cm of stone wool on the tank lid, on the walls - 15 cm. .rubles In January, they wound up no more than 2 thousand rubles. T

solid fuel

Firewood, coal, fuel briquettes.

Alexander Khadynsky

A solid fuel boiler (coal, firewood) requires constant attention, practically turning its owner into a stoker. Such structures can be used in places where neither gas nor electricity is supplied. They are the most affordable and are the cheapest. When using solid fuel boilers, it is especially important to observe fire safety measures.

Igor Larin

The degree of autonomy of solid fuel boilers can be increased by using a buffer tank - a heat accumulator in the system. Thanks to TA, heat is accumulated and the number of bookmarks in the boiler is reduced.

On average, the operating time of a solid fuel boiler on one tab is at least 3 hours, maximum 12 or more hours. The temperature regulator controls the air supply to the combustion chamber, and overheating protection is provided by a special valve and overheating protection heat exchanger.

When using solid fuels, there is no need to communicate with supply companies and obtain permits for installing a boiler. Everything is regulated by SNiPs, which must be followed during the installation of heating equipment. You should also follow the manufacturer's recommendations for fire safety.

As a backup heating system in case of a power outage, it makes sense to install a multi-fuel boiler or combine several heaters.

Alexander Khadynsky

An additional boiler is often used to increase the degree of automation of a solid fuel boiler, an electric boiler or a fireplace with a water circuit are connected to the circuit.

Autonomous heating in a private house through combined boiler rooms is an expensive option. These types of boilers combine three types of boilers at once - solid fuel, electric with a gas or diesel burner and are the most expensive of household boilers. In the event of a power outage, it is better to connect an uninterruptible power supply, which will allow the equipment to continue operating for up to 48 hours during the power outage.

Igor Larin

It is possible and even necessary to combine different devices for space heating, especially in regions where fuel shortages are possible.

Practical are systems where solid fuel boilers are combined with wood-burning fireplaces, i.e. the system includes an additional heat generator (fireplace), which supports or accelerates the heating of the system.

The benefit of using multi-fuel boilers is the ability to combine two types of fuel in the same equipment. In a boiler with two furnaces, solid fuel (wood, coal, briquettes) can be burned in one, and a burner (diesel or pellet) can be installed in the other. Thus, the homeowner, depending on the situation, can choose the type of heating that is convenient for him.

Anatoly Gurin :

- The undoubted advantages of pellet heating include: autonomy, its low cost relative to electricity and diesel fuel with propane. Among the minuses, it can be noted that it is necessary to find a place for storing pellets.

And low-quality pellets, due to incomplete combustion, reduce the efficiency of the boiler.

The boiler itself requires weekly attention, because. it is necessary to clean the burner and fill the pellets.

The time of continuous operation of the boiler can be significantly increased by installing an additional bunker for pellets.

In recent years, it has become more and more popular alternative heating systems houses built on heat pump etc. (see diagram).

Anatoly Gurin :

– The principle of operation is simple: the heat pump transfers warm air from the street to the house. The easiest way to imagine a heat pump is like a refrigerator: the freezer is in the ground, and the radiator is in the house.

The experience of using such a heating system shows that, having spent only 1 kW of electricity, we get 5 kW of heat.

Despite the fact that such a heating system has been known for decades, many are stopped by the high initial costs required for its installation.

A heating system is a long-term investment in your home, and lower initial costs are further offset by higher fuel and boiler maintenance costs.

Benefits of using a heat pump:

• low, 5 times less than when heating a house with electricity, ;
• when air circulates from the street to the house, there are no emissions;
• the system does not require maintenance;
• autonomy of operation: the heat pump requires only electricity, and in the event of a power outage, the heat pump can be easily powered from a gas generator.

How to understand what is more profitable to heat a house

The cost of heating consists of the cost of fuel. There is no universal fuel that is equally suitable for every region or home. Therefore, it is necessary to make a calculation based on the specific situation.

There may also be a situation when gas should be carried out in 1-2 years. At this time, you can put a solid fuel boiler and then install a gas burner in it.

Anatoly Gurin

It is necessary to choose the cheapest fuel in the region. It will be most profitable for them to heat the house. For an objective calculation, it is best to compile a summary table that displays the types of heat sources available, their construction costs, operating costs and service life.

In the long term, it is important to take into account such a factor as the convenience of using a heat source. Experience shows that no matter how cheap the fuel is, its low price can be crossed out by the minimum degree of autonomy of the boiler and an increased degree of attention to the operation of this equipment.

Alexander Khadynsky

It is necessary to conduct a brief analysis of the most probable methods of heating with one or another type of fuel.

Knowing the power of the boiler, you can calculate the cost of heating costs per month. Approximate calculation - 1 kW is needed to heat 10 sq.m. (provided that the distance from floor to ceiling is up to - 3 m), in addition, you need to take a margin of 15-20%, which is necessary for preparing hot water.

On average, boiler equipment operates for about 10 hours / day. The heating season in central Russia lasts 7-8 months a year, the rest of the time the boiler works to prepare hot water and maintain a minimum temperature of + 8C in the house.

Total:

Electricity: Approximately 1 kWh of electricity is consumed to produce 1 kWh of thermal energy.

Solid fuel: Approximately 0.4 kg/hour of firewood is consumed to obtain 1 kW/h of thermal energy.

Diesel fuel: Approximately 0.1 liter of diesel fuel is consumed to obtain 1 kWh of thermal energy.

Gas: Approximately 0.1 kg of liquefied gas is consumed to produce 1 kWh of thermal energy.

In the long term, it is necessary to take into account the increase in fuel prices, based on the trends of recent years, and the payback period for the initial investment.

Thus, the choice of a heating system consists of a whole range of measures and engineering solutions that require a balanced approach and a thorough analysis of each specific situation.

In conditions when energy carriers are constantly becoming more expensive, alternative heating of a private house becomes relevant. Owners of dachas and cottages are looking for acceptable options for heating their property, considering a variety of proposals: from solid fuel boilers to solar collectors. Each heating option, which differs from the standard, has certain advantages and disadvantages. We will talk about them today.

A bit about alternative energy

For some homeowners, any opportunity to give up gas heating, which is common in rural areas, may be a suitable alternative. Others are striving for complete autonomy and are looking at opportunities to accumulate and use solar energy.

Environmentalists advocate for sustainable land and water energy. Some are concerned about how the air in the house warms up and how the heaters affect the humidity in the room.

The use of natural energy sources is currently quite expensive and pays off, as a rule, within ten or more years.

In general, modern alternative types of heating look quite diverse:

• boilers operating on solid or liquid fuels, as well as on biofuels;
• heat pumps based on the use of geothermal energy;
• solar collectors using the thermal energy of the sun;
• infrared heaters of various types;
• "warm plinth".

More recently, alternative heating methods also included systems such as "warm floor", which appeared on the market not so long ago. Today, they have become quite familiar and perfectly complement, and sometimes completely replace the usual methods of heating with the help of radiators.

Pay attention to the article with an overview of energy-saving heating systems: their types of advantages and disadvantages:.

It would seem that the use of a gas boiler has many advantages. Many thousands of houses are heated in this way. However, the requirements of homeowners for the quality of heating are constantly growing.

It is worth noting that it is technologically not so simple to connect a gas boiler to the main. Problems arise in the process of registration of all relevant documents. In addition, the cost of gas is constantly rising. Finally, the quality of heat also causes criticism. With the help of a boiler it is difficult to heat the house evenly: the temperature near the radiators and the floor is much higher than in the center of the room.

Option #1 - biofuel boiler

To refuse gas and replace it with another energy carrier, it is enough to change the boiler. The most popular options are electric and solid fuel. But heating an energy carrier with electricity is not always economically viable.

An interesting option would be to use boilers on. For their work, special briquettes and pellets are used, but materials such as:

• wood pellets and chips;
• granulated peat;
• straw pellets, etc.

The use of briquettes allows you to make the fuel supply to the boiler automatic, you will no longer need to worry about it. However, it should be noted that the cost of such a boiler can be ten times higher than the price of gas analogues, briquettes are also quite expensive.

Please note that a properly arranged fireplace is a good alternative to modern heating methods. It is quite capable of effectively heating a small cottage.

You may be interested in an article on how you can make a bioreactor with your own hands, is it cost-effective and are special permits required:.

Option #2 - use of heat pumps

Geothermal heat pumps heat the house using energy from the earth or water. In summer, such a system works like an air conditioner, i.e. helps to cool the building by returning excess heat to the ground. This is an environmentally friendly type of heating that uses renewable resources.

If we compare the heating costs of heat pumps with gas boilers, we can note significant savings: about 15%. However, alternative heating systems of this type are rare, since the costs of their creation remain very high.

Please note that the heat pump needs a constant supply of electricity to operate. Therefore, you should not mount such a system in an area where electricity is often turned off. You can solve this problem with your own generator, but as a result, installation and maintenance costs will increase markedly.

Option #3 - use solar collectors

These are plates that are usually installed on the roof of a house. They accumulate the heat of the sun's rays and, with the help of a coolant, transfer the collected energy to the boiler room. Heat enters the heat exchanger, which is built into the storage tank. After that, the water is heated and can be used for heating, domestic needs, swimming pools, etc.

Solar collectors can work effectively at low temperatures and cloudy weather

Thanks to new technologies, solar collectors are able to receive heat even in cloudy weather or when the air temperature is below zero. However, the maximum effect from their use can be obtained in the southern regions, where the amount of solar radiation is quite high. In colder areas, solar collectors will better cope with the role of additional, rather than main heating.

Option #4 - infrared heating

Infrared heating is becoming more and more widespread. Such alternative sources of home heating are relatively inexpensive and very easy to install. Compact infrared heaters effectively heat rooms, besides, they can decorate the interior.

No less popular is the infrared film, which is used when installing the "" system. It is laid under a layer of decorative flooring, which greatly facilitates installation. There is no need for complex repairs, it is enough to remove the floor covering, lay the film and lay a new floor covering.

A warm baseboard allows you to heat the room efficiently and evenly

Also, an interesting solution for the home can be a system called "". This system is mounted along the walls, which heat up first and radiate heat into the room, preventing its penetration to the outside. As a result, the air temperature in the room becomes very uniform.

These alternative sources of heating for a country house are also not too expensive to purchase. And their installation is easy. For example, the electrical system of a warm baseboard can be installed in just a couple of days. In this case, it will not be necessary to mount additional communications, which means that the interior of the house will not suffer. When using such heating, the humidity in the rooms remains optimal.

Due to the constant increase in the cost of gas and electricity, many users began to pay attention to environmentally friendly and economical maintenance of building heating systems.

The most popular of them are geothermal systems, windmills, biofuels and solar systems. Alternative methods of heating a house, although they have an initially high cost, quickly pay for themselves.

What are Alternative Heat Sources?

The main task of the systems is obtaining energy from renewable sources. Most alternative devices can be used to generate heat in any area, which indicates ease of use and minimum requirements.

Features of solar systems for a private house

solar collector can be used for heating apartment buildings and private houses. Solar systems are also often used for heating water for personal needs of consumers. Solar systems can operate in various modes and, depending on the selected equipment, provide energy generation during the whole year or certain seasons.

Panels and manifolds due to special absorption coatings heat the coolant inside installations. The liquid is supplied to a special reservoir, from which it enters the heating system of the house or into the hot water circuits.

Solar panels pass the coolant between the plates, and the tubular system raises the temperature of the liquid due to the vacuum between the outer and inner flasks. Under the influence of ultraviolet rays, the absorption layer begins to interact with the liquid and can heat it up up to 90 degrees.

Solar collectors are sources of heating of the coolant supplied directly to the heating circuits. To use solar energy you need an expansion tank and a pump, which will pump out water from the installations when the set temperature is reached.

pros heliosystem:

• Tubular collectors easy to install.
• Solar panels are different low cost and high performance during the warm season.
• The equipment is suitable for use in various climatic zones.

Attention! The main disadvantage of solar collectors and batteries is their high cost and fragility.

Wiring diagram for wind generators

Installations represent a device with blades, during the rotation of which electric current is generated. Windmills can be of different sizes and shapes, depending on their purpose and terrain.

During the operation of wind generators, batteries are charged, which subsequently supply energy through the converter for heating buildings. Installations have two types of axes of rotation - horizontal and vertical.

Photo 1. Scheme of connecting a wind generator to the mains through the controller to household appliances.

Equipment with horizontal mounting blades are designed to work in the area where the average annual wind speed more than 5 m/s.

Windmills with vertical axis rotations, due to their compact dimensions, are optimally suited for use in private homes. The required average annual speed of wind flows in this case should be above three meters per second.

Among the advantages of generators can be noted environmental friendliness, ergonomics and renewable energy source. The disadvantages of windmills include them instability, low efficiency, high cost.

Geothermal type of heating - reliability and durability?

Heat pumps represent two circuits with heat carriers connected with special equipment. One of the circuits is below ground level, and the other is located in the building that it heats. Geothermal heating system uses heat extracted from the bowels of the earth. In places where equipment is laid, the average annual ambient temperature is 8-10 degrees.

The liquid that is in the external circuits is heated from the ground or water and fed into the pump, after which the device cools the substance to negative temperatures, and the released heat is redirected to internal heating system. Geothermal equipment will be an excellent option for space heating using low-temperature appliances.

Thermal systems installed in three ways:

• Horizontal.
• Vertical.
• Underwater.

To the pluses geothermal heating can be attributed to the inexhaustibility of the natural resource, the absence of emissions of harmful substances into the atmosphere, the high efficiency of the system. cons equipment is a low coolant temperature in the internal circuits ( within 35-60 degrees), high cost of installations.

When biofuels come to the rescue

Biofuel is substance derived from animal or vegetable matter, organic waste industry, the results of human activity. Biofuels come in many forms, but the most common options are pellets or briquettes.

For home heating with biofuels need to install a boiler, which will be compatible with an alternative energy source.

When burned, the substance releases heat, which heats the liquid in the heating system and ensures that the desired temperature is maintained.

The main advantage this type of alternative energy is its mobility. In the process of using biofuels to heat buildings, no harmful substances are emitted into the atmosphere. The main disadvantage raw material is use of large areas for sowing crops from which this fuel can be produced.

Is it possible to install alternative heating with your own hands

Most systems difficult to install independently, as the installation process requires special tools and skills.

Wind turbine connection diagrams are selected individually depending on the task at hand. Wind turbines are connected to the controller, which charges the batteries and transfers electricity to the inverter. This design can be perfectly used to provide a private house with electricity.

Heat pumps most often installed vertically. To install the equipment you will need drilling wells to a depth of more than 50 meters. The size of the circuits depends on the power of the heat pump. Sometimes the total length of wells reaches two hundred meters. External circuits are connected to a pump, which takes heat from them and transfers it to the house heating system. Low-temperature equipment receives a heated coolant and heats the building.

Biofuel boilers mounted on a pre-prepared screed, the thickness of which is at least 7 cm. For the most efficient operation of the heating system, connect buffer tank, representing a water tank.

The volume of the device is calculated depending on the power of the boiler. If the heating equipment is volatile, then electricity should be supplied to it.

The chimney that is installed on the biofuel boiler must be equipped with condensate collector and have a diameter at least 18 centimeters. The height of the chimney is usually more than four meters. To protect the heating system from back pressure and siphon drainage, a check valve is installed in it, which is located on the general water supply pipe. Fluid regulation and temperature control is carried out using balancing and mixing valves.
