What are electric water heaters? What to consider when choosing instantaneous water heaters

The presence of warm water in the country is required for taking a shower, washing dishes, washing and other activities that we are used to in a city apartment. Quite often, the problem of heating water in a summer cottage is solved by purchasing an electric water heater. Such devices have many advantages, however, before purchasing such a heater, you should familiarize yourself with its varieties and other nuances in more detail.

pros

• Thanks to the installation of a heating device in the country, there will always be access to hot water, which will provide a certain comfort of living in a summer cottage.
• Electrical water heaters choose for summer cottages more often, since not all sites have access to natural gas.
• Models of water heaters for cottages do not consume much energy.
• The range of water heating devices is quite extensive. They are represented by devices with different volume and different power.
• There are options for heaters that can be filled with water manually, that is, they do not require plumbing or installation of a pump in the well.

Mounting small heating devices, often chosen for summer cottages, is quite simple.

Kinds

Choosing a water heater suburban area working from electrical network, you can find different options.

Storage heaters

Such devices are most in demand for heating water in private homes. They are also called boilers. Since the storage device must be connected to the water supply, it is chosen for cottages with centralized water supply or for areas with an automatic pumping station.

Water enters the boiler through the security system and is heated inside from the heating element, which is connected to the thermostat. When the water inside the tank cools down a little, the heating element turns on and the temperature rises to the set temperature. The disadvantages of this type of electric heater for summer cottages include high energy consumption, relatively high price and the dependence of functioning on the pressure in the water supply.

Flow heaters

They are chosen for summer cottages where it is impossible to install a storage device. The flow device is installed next to the draw-off point, connecting a pipe to the heater through which cold water will flow. This water, after entering the heating device, will move through the tubes and be heated from the heating elements to the desired temperature. The heating is regulated either by a special valve or by means of a control panel.

It is very convenient to use such devices for heating water, because warm water comes from the tap almost immediately after opening it, however, there are some limitations for their operation. They concern both the pressure of water (if it is insufficient at your dacha, a pump must be installed), and the load on the wiring (it will be significant at the peak of heating), and the performance of the apparatus (it is small).

Autonomous heaters

Such devices are in demand for cottages with a lack of water supply. They are similar to washstands and are a container in which the top cover opens to fill this container with water manually.

A heating element is installed inside the tank, and a tap is located below. Some models have several tanks - in one the water is heated, in the other there is cold water, and the tap functions as a mixer. Installing such a heater is very simple, and it will help out in an area with a well that does not have a pump. In addition, the cost of such devices is low, and their operation is quite economical.

Such a portable water heating device is installed directly on the faucet and heats the water passing through it thanks to the built-in heating element. It is chosen if it is required to heat water at one point. The main advantage of this device is its compact size.

The disadvantage of this type of heater is rather low productivity and high electricity consumption.

Manufacturers and prices

Accumulative heating devices powered by the mains are produced by many manufacturers.

• In our market, boilers from Termex, Electrolux, Ariston, Timberk, Ferolli and other brands are especially in demand. Their cost depends on the volume of the device and its other characteristics. For example, a device for 10 liters can be purchased for 4000-6000 rubles, a boiler for 30 liters will cost 6000-8000 rubles, and for a device with a volume of 80 liters you have to pay an average of 7000-12000 rubles.
• When buying a flowing electric heater, most often they choose devices from Electrolux, AEG, Termex and other brands. You can buy such a device, depending on its power, both for 2000 rubles and for 7-8 thousand rubles or more.
• Faucet flow heaters are manufactured by Aquaterm and Delimano. Models from Aquatherm consume up to 3.5 kW, are protected from low temperature and power surges, allow you to adjust the water temperature and are presented in different designs. Such heaters serve for a long time and cost in the range of 3-5 thousand rubles.
• Models from Delimano attract with their design (they are made in white), durability, instantaneous heating of water, ease of control of the heating level, ease of operation. In appearance, such a heater is similar to a conventional mixer. It is made of plastic and metal, and the inside is lined with ceramic insulation for greater safety. Such a device costs an average of 5,000 rubles.
• The most famous manufacturers offering bulk water heaters are Ariston, Bosch, Alvin, Atlantic, Atmore. average cost such equipment is 1500-2500 rubles.

Reviews

After evaluating customer reviews, it is noticeable that most often for the dacha where they live in summer period, select storage water heater. Dacha owners note that such devices are quite economical, easy to use and regularly heat water to the required temperature. Flow devices are less in demand due to their significant power and low productivity.

About the flowing electric taps-heaters, the reviews are mostly good. They are purchased for heating water in one place. At the same time, users emphasize that such a portable device is very reliable and heats water quickly enough.

As for bulk models, summer residents are very pleased with them, in areas where there is no main water supply. They are glad that they can pour water into such a device manually and get hot water even in such cramped conditions.

• First of all, pay attention to the power of the heating element in the selected water heater. In most cases, the buyer needs the device to be economical, and the country wiring can withstand the load from its operation.
• If in the country you will heat water at only one point (for example, only in the kitchen), then you can look at a portable heater mounted on a faucet. If there is a need to provide hot water several points, such heaters will not work and you should opt for a more powerful flow device or a storage model.
• Decide on the volume of the tank. At the same time, keep in mind that heating a significant amount of water at once, although it will be longer, will come in handy if you want to take a shower, especially if the whole family lives in the country during the summer.
• Take close attention safe operation of the heating device. Make sure the model you are purchasing has reliable protection from short circuit and fire.

Choose a heater from a well-known manufacturer with a long warranty on the device. It is better to buy a reliable device right away than to spend money on its maintenance and repair in the future (especially if the cottage is far enough from the city).

Connection and installation

Having chosen and bought the necessary water heating device, it is transported to the country house, after which a place for installation is chosen.

Regardless of which type of water heater you have purchased, installing it is quite simple. To begin with, the load from the apparatus to the surface is determined in order to select fasteners. To do this, add up the mass of the device itself and the maximum volume of water that can be in it. It is advised to install the device on a solid wall, picking up fasteners with some margin.

The summer season is associated with a trip to the country house, the repair of city water arteries, and the lack of hot water supply. flowing electric water heater, a compact device, will solve the problem. The advantage of the device in instant heating running water in the faucet or in the shower. No space-consuming storage tank required. Due to the heating elements built into the jacket, the passing water, washing them, heats up.

The principle of operation of instantaneous water heaters

Basically, wiring hot water need not. Heated water can be supplied through the line cold water, but then it cannot be diluted.

There are two fundamental various schemes heating - flowing pressure and non-pressure. In this case, the circuit is considered non-pressure, since the water inlet for heating after the valve, and its free flow to the shower, passes under atmospheric pressure. In this scheme, a temperature controller is used, the flow rate at the inlet is determined by the user manually. The circuit includes a valve to turn off the power when there is no water in the pipe. This prevents water overheating and accidents. A flowing electric water heater can operate at a power of 2-8 kW and does not require separate wiring.

The pressure flow system is more complicated. In order to obtain the required flow and temperature parameters, two control systems are involved - pressure and temperature. Pressure systems are complex, use additional options, and cost much more. But they are designed to connect several sampling points, and turn on automatically when a flow appears in the pipe. The system requires a separate wire, designed for the power of the device.

So that when heated, water does not create deposits on the heating elements, it is subjected to magnetic treatment with a compact activator built into the system. An electric flow-through water heater is an alternative to a boiler. The equipment has the same tasks, but a different principle of operation. In the boiler, water is heated constantly, with a power of 1-2 kW, for flow heating it is necessary to give a salvo with a power of 3-30 kW, depending on the selected equipment. On the other hand, excess water in the tank cools down, energy is wasted.

A flowing electric water heater takes power only when using a tap or shower.

Flow heater device

Numerous Models flow heaters using the same heating methods. Brands are distinguished by design and materials used in the layout of products. The installation of an electric flow-through shower is carried out from models of pressure and non-pressure rows. low power non-pressure devices do not allow you to get water warmer than 60 C. But this temperature is standard for supplying coolant to the mains district heating. A non-pressure heater is able to serve only one point of analysis. However, the device is compact, easy to install on its own and can provide the need, provided that a special nozzle is used. Due to the different sections of the inlet and outlet of water, the time spent by the liquid in the heating chamber is regulated. Outflow from the narrow end creates a comfortable pressure.

Here is a drawing of a non-pressure flow heater AEG BS 35 E made in Germany. The company specializes in the production of flow heaters different categories. A non-pressure device can operate at low power and operate a maximum of two points in turn. The pressure water heater AEG RCM 6 E can be installed on mains up to 10 bar. Bulb and heating element in copper version. Such heaters are installed in a separate cabinet, and they cannot be called economical.

Installing an instantaneous electric water heater on a faucet

At first glance, the faucet-mounted device appears to be an ordinary faucet. Only the wiring gives away the placement of the appliance. A coiled heater and a regulator that controls the process are hidden in the robust body of the tube. In design solutions, various mains supply connections can be used. All devices include:

• flask;
• heater;
• temperature relay with shutdown function;
• a water movement relay that gives a start command;
• water filter;
• load regulator.

Usually instantaneous electric water heaters are used for summer cottages. You can wash dishes and hands with warm water from a low-power device. The lower the power of the device and easier execution the cheaper it is. For seasonal use, you can find a model costing less than three thousand rubles. In this case, you will have to manually regulate the flow of water. The higher the inlet flow, the lower the outlet temperature. It is considered optimal if the device gives the flow-temperature ratio:

• washing in the kitchen - 3-5 l / min at t 45-50 0 С;
• washbasin - 2-4 l / min at t 35-37 C;
• shower - 4-10 minutes at t 37-40 C.

Such indicators will give a device with a power of 3-6 kW. The crane model KDR-4E-3 of the Delimano brand provides heating under these conditions up to 60 degrees. Inexpensive instantaneous water heaters from Electrolux (Electrolux) took first place in the ranking for price and functionality. It is worth paying attention to Electrolux Smartfix 3.5 T and Garanterm GHM 350, Russian-made brands.

Choosing a flowing electric water heater for a country house

There are certain norms of water consumption for each person. Therefore, it is necessary to calculate the purchase of a water heater based on the total need for hot water. For a large building with several sanitary points, it is better to use a storage heating system. Boilers operate on a conventional network and consume energy economically.

If there is a need to install an electric instantaneous water heater in an apartment building old building, the device should be selected in the power range up to 8 kW, with a separate line.

If a voltage of 380 V is supplied to the building, then you can get a powerful device. It is important to choose a safe heater that uses:

• enameled heating chamber;
• elements in a stainless casing;
• flask and heating elements made of copper, with quartz coating.

How to choose the right instantaneous electric water heater in terms of power? Experts advise:

• in summer, a power of 3.5 kW is enough, since the water has a temperature of about 18 degrees;
• in winter, models with a power above 5 kW are effective;
• models with options that require a power of more than 7 kW should not be purchased in a standard apartment.

The range of electric instantaneous water heaters, their prices and characteristics

The demand for flow heaters is due to the need to create comfortable living conditions under any circumstances. The compact size of the devices allows you to install equipment in cramped conditions. The water heats up within a few seconds and it is possible to maintain a stable indicator.

Domestic water heater: functions

Electric storage water heaters are boilers that heat water collected in an internal tank to a predetermined temperature. Thanks to thermal insulation and automatic operation of heating elements, devices for heating water maintain the temperature at the required level. The described boilers are able to heat water up to 75-80 degrees, after which they maintain this temperature automatically. Since heating occurs for a long time, that is, gradually, devices for heating water when used for summer cottages do not require significant energy costs.

It is thanks to this quality that boilers for the home can be installed in almost any room where a constant need for hot water is required. Another advantage of electric storage water heaters in that heated water can be consumed simultaneously by several water intake points. The capacity of boilers can vary from 10 to 500 liters, you need to choose one or another option in accordance with the planned water consumption. Almost all water heaters of this type operate only under pressure. tap water, that is, they are pressure.

The lineup

One of the most popular storage electric water heaters are devices of world famous companies:

• Electrolux
• Ariston
• Thermex
• Stiebel Eltron
• Garanterm

Storage water heaters for the shower of these manufacturers have long established themselves as reliable, energy-intensive and durable. The Timberk SWH FSM7 50 V wall-mounted water heater has, for example, a very flat body made of mirror polished of stainless steel, equipped electronic control, which allows you to select the desired power mode and set the desired water temperature.

Ariston Platinum SI 200 T boilers are intended mainly for small businesses, as they have a large volume (200 l), do not require constant additional maintenance, and are equipped with a high-quality stainless steel tank. Separately, it is worth mentioning the Ariston devices designed for summer cottages. They possess titanium coated, as a result of which they have a large guarantee, while being in the middle price category.

How to buy a water heater in Moscow inexpensively?

The catalog of our online store boasts a variety of models - from the most budgetary household water heaters before industrial appliances, the price of which is more than 400,000 rubles.

Boiler not able to heat right amount hot water or is it always needed immediately? The only reliable and available source energy - network 220 or 380 V? There is no desire, opportunity, conditions for the installation of bulky equipment? Not sure how to choose an instantaneous electric water heater? The information in the article will give answers to all questions.

Installation of flow heating of water is arranged quite simply. The foundation engineering solution- heat transfer zone. It contains a heating element of one type or another.

1. The classic solution is a heating element, inside of which there is a wire spiral.
2. A more modern heater is tubular. This is a moisture-proof inductor that has good efficiency and heats up to high temperatures.
3. The most technologically advanced solution is the system induction heating. It consists of an electromagnetic coil and a core, which is heated by Foucault currents.

To allow the temperature of the liquid passing through the instrument's circuit to be adjusted by the user, heater manufacturers offer a range of control circuits. Among them, there are necessarily security systems. They prevent the heating of water to the boiling point or above the set maximum value, idling, short circuits and other emergencies.

The flow heater has an impressive list of advantages. They make it a very convenient product for quickly, within seconds, getting hot water. For example, future owners are attracted to:

• compact size;
• no special installation requirements;
• the ability to work with any flow of water;
• clear adjustment mechanics;
• equipment that allows you to immediately select a model that meets your needs.

But an instantaneous electric water heater also has disadvantages that can create problems in the average apartment or house. For example:

• a powerful device, having a consumption of 7 kW or more, will easily overload weak wiring;
• the number of liters of water that the unit is able to heat per minute to a comfortable temperature may not be enough to meet the needs of the family;
• an incorrectly selected type of water heater can be used inefficiently.

An accurate assessment of all parameters will allow you to choose a flow heater for a house, cottage or apartment, the characteristics of which will be very attractive. Let us dwell in more detail on those features of the device that should be considered when buying.

Types of flowing electric heaters

As mentioned above, all flow type devices are built on the same basic circuit. Deciding which is better to buy an electric water heater is, first of all, according to its performance characteristics and design. On the market are:

• wall-mounted devices with vertical body orientation, with bottom piping. They can supply water to a shower through a flexible hose, to a gooseneck or to a water take-off line;
• wall-mounted heaters with lateral supply. They are optimal for location behind a partition or wall. Unregulated models work perfectly: water, when taken in an amount not exceeding the performance indicator of the device, always has an exactly set temperature;
• top-mounted appliances are optimal for the kitchen. They are easy to install under the countertop, inside the furniture set;
• tubular flow heating systems. Their connection is made directly inside engineering systems, installation is carried out directly in the line of the pipe passage. The fluid inlet and outlet are located at the ends of the heater, and the adjustment systems are either not provided or are designed for a single heating mode setting. A separate product segment is compact water heaters manufactured in the format of a stand for a kitchen sink faucet.

The last type of flow heater can act optimal solution if the owners chose it for installation in the apartment. Such a device can be paired with a storage class boiler through a three-way mixing valve. This ensures constant availability of hot water, the possibility of intensive extraction and a constantly comfortable liquid temperature.

What to consider when choosing a device

Let us dwell in more detail on the complex of characteristics instantaneous electric heater, the choice of which will allow you to get a device that does not create trouble and provides a sufficient amount of hot water. Immediately, we note several features that allow you to better evaluate the device.

1. The specified performance of a flow heater is the amount of water that it is capable of delivering in a constant flow at the maximum (indicated in the passport) temperature.
2. Unregulated devices or those equipped with mechanical control systems always have a clear power consumption indicated in the characteristics of the device. At the same time, electronically controlled flow heaters use as much energy as needed to heat water to a specified temperature.
3. Devices equipped with a shower head are not always suitable for giving. The nozzle has very small holes. It is suitable for washing dishes or hands, but it will be inconvenient if the water heater is placed in the shower.

Devices intended for one point of water sampling are called non-pressure. Installed at the entrance safety valve, which provides an internal fluid pressure of 1 atmosphere. Such a water heater cannot supply water more strongly than its design allows, even if it whips from a “cold” tap with an intense stream.

Devices designed for several water sampling points are capable of withstanding pressures up to 10 atmospheres. They can be installed directly at the entrance to the apartment and pick up a performance that is sufficient for everyone. household needs.

Choosing an electric instantaneous water heater by power

Before going to the store, you should consult with electricians. The calculation of the average wiring in a modern house is based on the ability to connect several powerful consumers. This is a washing machine, oven, electric grill. Therefore, a small flow heater with a power of 4-6 kW can be safely used if it is turned on for a short time (up to half an hour).

If the house is old, the wiring is weak, it is recommended to make a separate input to the apartment, from which the instantaneous water heater will be powered. Ideal Solution- lead to the shield of the bus flat directly from the basement or from the central distribution point. In this case, one more problem can be solved: to provide a neutral wire, which is in modern houses, is necessary to connect the device, but is not available in old buildings.

It is recommended to make a separate entry in any case. However, realizing that no one will do serious repairs with wall chasing or opening wire laying channels without special need, it is worth carefully evaluating the capabilities of existing wiring and choosing a water heater that can work in existing conditions without accidents.

Selection by water consumption

As mentioned above, the nominal performance is indicated in the passport for the heater. The flow of water given out by the device is always diluted. Therefore, if 3 liters of selection per minute with a temperature of 55 degrees are declared, such indicators are enough for a comfortable shower.

The second factor to take into account is the difference in instrument performance over the seasons. The water in the supply pipe varies in temperature. In summer it is warmer, in winter it is very cold. For example, in summer, a water heater with a power of 8 kW will provide a selection of 3.1 liters of water with a temperature of 55 degrees (18 at the inlet). And in winter, when water is supplied at 6 degrees, the output will only be 2.3 liters of hot liquid.

To successfully choose a device, you should focus on its class and the declared performance indicators. For example, for a non-pressure device that is mounted at one sampling point ( kitchen sink, bathroom, shower), a capacity of 3-4 liters will be enough (less if there is no habit of taking a shower with a good flow of water).

For pressurized water heater with multiple sampling points is accepted minimum score 3 liters per minute for one consumer. Each subsequent tap should add 1.5-2 liters to the recommended performance of the device.

Heating element features

The class of the heating element can be decisive factor and determine which company to choose a water heater. For example:

• the simplest devices use one or more heating elements. They can be anodized or copper sheathed;
• more advanced devices are equipped with ceramic tubular heaters. They are durable, expensive, efficient;
• the most best heaters— spiral blocks protected by glass. They do not require maintenance, slightly change the rate of heat transfer during the formation of scale.

Spiral induction heat exchangers are the most technologically advanced solution. During their operation, very little scale is formed, since the Foucault currents, in addition to heating, cause the vibration of the central core and the current spiral. Some water heaters of the Swedish Electrolux brand are equipped with such heaters.

The material from which the heater is made

The heater housing is the last thing worth evaluating. Each buyer has a personal rating. For example:

• practical people will prefer plastic. It is easy to care for him, but over time, scratches, roughness, collecting dirt inevitably appear;
• cases covered with enamel look rational. They are durable, the surface is durable, wear-resistant, looks aesthetically pleasing;
• Anodized body parts look stylish and impressive. However, the coating may wear down to the base over time. Excellent strength indicators for the titanium layer. Such a case is an expensive solution, but it looks extremely attractive;
• all-metal, polished, stainless steel or alloy water heaters are the height of perfection in the eyes of some buyers. But there is one factor to consider. On a smooth mirror surface metal stains and other visual imperfections will always be visible. It will require careful, constant care.

Which company is preferred

Knowing how to choose a flowing electric water heater, one cannot but mention the companies that are leading in customer preferences. At one end of the scale are simple, inexpensive, and reliable solutions. How bright representative, the Polaris brand can be noted. Here are classic, simple heating elements, moderate power consumption, maintainability and availability of spare parts.

At the other end of the scale are products from Electrolux. Here technological innovations are used. For example, induction heating blocks, spirals protected by glass. The price of water heaters is high, but the reliability is even higher, the products do not require maintenance or repair long years.

As a conclusion

There is a lot of talk about flow heaters, but always one-sidedly. The attitude to this device can be described in one phrase: “don’t like it? You just don't know how to cook it." Whatever modern types of flow heaters are considered, each will require integrated approach. It is enough to provide the device with a reliable power source, evaluate the water consumption and choose the appropriate model, and connect it where it will be most effective. And then the purchased heater for many years of work will never make you disappointed in yourself. You just need to go to the store and know what to look for when buying.

The water heater is becoming increasingly popular, making up for the lack of heat when the central hot water supply is turned off. These devices provide citizens necessary quantity hot water. Affordable cost, low power consumption and ease of installation make the equipment attractive.

The periodic shutdown of hot water makes it necessary to purchase water heaters that help provide comfortable conditions residence. Today, there are several types of water heaters on the market: flowing, storage, bulk and combined.

For backup use in apartment buildings ideal option becomes a flow water heater. It does not take up much space and can provide the necessary heat without waiting for a long heating.

Flow type electric heater is produced by:

• pressure;
• Pressureless options.

Pressure plunge into water pipe. Such a system will be able to provide several sources of water analysis. Insert the device after the filter, providing more long term operation. An electric heater is able to heat water to the required temperature in a few minutes.

The principle of operation is simple. Tap water from the pipe passes through a hot heating element, heating up to a certain temperature, and then enters the faucet. In this case, electricity is spent only at the moment of switching on.

A pressurized water heater requires separate wiring, or connection to electricity designed for an electric stove. Models are single-phase 3 - 12 kW and three-phase from 3 - 30 kW.

Non-pressure options have less power, and only one point of analysis. They can be installed on the walls next to the faucet and connected with a hose to the water pipe.

The main advantages of flow devices:

• Miniature sizes;

Such designs are suitable for private houses without gas supply. They do not require reinforced wiring and are easy to install.

Electric boilers - this is the name of a sealed tank, with located inside heating element. Modern models equipped with a thermostat that regulates the temperature. For maximum heat retention, the tank is protected by a layer of thermal insulation.

The hot water tank is connected to the mixer. Under pressure, the boiler is filled with water. Teng heats water to a certain temperature and turns off. When parsing water, titanium is filled with cold masses. The heating switches on automatically. Having reached the desired temperature, the unit turns off again.

Manufacturers produce water storage Appliances various capacities. The parameters vary from 5 to 120 liters. When purchasing a unit, it is necessary to take into account the required water consumption. To take a shower, 1 person needs about 30 liters of water. Based on the number of people in the family, you can calculate the required volume of the boiler.

Boiler Advantages:

• Ease of installation;
• Connection of several sources of water analysis;
• Does not require additional wiring;
• Security.

IN small apartments installing a large tank may not be possible, so some are limited to small sizes.

Instantaneous water heaters can be powered by electricity or natural gas. The design of the device has a drive, which serves as a reservoir for the supply of hot water. If the flow rate increases, the flow heater automatically turns on.

Some models require a separate electrical connection. Less powerful, plug into an ordinary outlet. The manufacturer produces a storage device from 5 to 30 liters. Such boilers are ideal for an apartment when it is impossible to install a flow-through option due to the state of the networks and there is simply no place to install a large titanium.

The flow-accumulative electric heater has its advantages:

• Able to work in 2 modes;
• Small size;
• Easy installation;
• Ease of use.

A geyser is an economical choice for daily use of hot water. It will not take up much space and will become great solution for the private sector. The price depends on the power of the column, relatively higher than the flow electric option, but during operation, savings on gas fuel will become obvious.

If we compare storage options, gas boilers have great power capabilities. Therefore, when choosing between gas and electricity with equal access to energy resources, preference should be given to the first option. For example, a tank of 150 liters gas construction heating will bring to the desired temperature in an hour. Electric boiler to cope with the task in 3 hours.
