Features of the device for heating a country house with electricity

Electrode

Work electrode electric boilers heating is built on heating water when an electric current moves through it between two electrodes. Electrode heaters are convenient due to their compactness, low cost, lack of scale during operation, safety and the ability to easily adjust the power.

Electrode units are characterized by high efficiency - 95-98%, which contributes to the most economical consumption of electricity. There are also significant drawbacks. For example, it is forbidden to use non-freezing liquids and ordinary water as a heat carrier in systems with electrode boilers. To ensure the efficiency of the system, it is necessary to pour special water into it, in which salt is dissolved in a certain amount. In order for the work to proceed without failures, and the coolant does not boil, water must circulate through the system at a certain speed.

To connect an electric boiler, a diploma with higher education is not required, but certain knowledge will not interfere. If you strictly follow all the instructions and follow the safety precautions, the finished heating scheme will provide efficient heating of the home.

Electric heating of a private house

Water electric heating

Electric heating of a country house is an environmentally friendly source of heat, which does not pollute the air harmful waste products. The installation of electric heating must begin with the development of a project, regardless of the specifics of the design, the size of the house, and the price of the equipment. Installation of electric heating of a country house takes place during the construction phase. Installation of electric heating carried out in a country house or in the country, in the event that it is impossible to join the gasification systems.

Pros and cons of electric heating in a country house

Electric heating systems of a country house are beneficial only if you are serious about saving electricity.You can regulate the power of the boiler yourself or the built-in temperature sensor system will do it for you. If the degree of the coolant begins to exceed the set value, then the heating mode is automatically turned off. Switching on occurs only after the temperature in the room has dropped. The electronic power control system makes automatic adjustment in steps, and microprocessor units carry out smooth adjustment.

Therefore, you have a constant possibility of power control, which allows you to use only that part of it, which is quite enough for electric heating. All this in general suggests that electric boilers can be both efficient and economical. Electric boilers can not only heat the room, but also provide hot water using the flow method or with the help of an additional external boiler of the required volume.

Installation and installation of such equipment provides advantages, because. small overall dimensions and modern design allow them to fit into any interior and at the same time do not take up much space, because electric boilers do not require a boiler room and a chimney. With proper installation and operation boilers have a long service life with a minimum of control.

The advantages include:

• Possibility of centralized management
• Power regulation
• compactness
• Noiseless operation
• Reliability
• Durability
• Low price

And there is only one minus - the high cost of electricity, but, as we have already said, even it can be eliminated.

Electric boilers are the basis of the system

There are two types of boilers: wall and floor. The main difference is power. For wall-mounted, it ranges from from 5 to 60 kW, while for floor standing over 60 kW. Most of the boilers, with a power of up to 9 kW, operate from a single-phase 220 V network, if the power exceeds 9 kW, work will be carried out from a three-phase network. The second point, according to which the division of all electric boilers is the circulation of the coolant. It can be natural or forced.

The device of the convector system

One of the popular ways to equip the heating of a private house with electricity can be considered the use of convectors, devices that use air convection in their work.

The device and principle of operation of the convector

Thermostat-controlled heating elements heating elements are built into the metal case of the heater. Each of them is a high-resistance conductor placed in a ceramic sheath, hermetically sealed in an aluminum or steel case. This design of the device allows you to increase the area of ​​interaction with air and effectively carry out its heating. The operating temperature of the heating elements varies from 100 to 60C.

Convectors are dependent on the supply of electricity, which makes their owners think about having an alternative heating system in case of an accident.

After turning on the convector, heating of the heating elements begins. According to physical laws, the cooled air goes down. Here it enters the structure through the lower grate and passes through the heating elements, gradually warming up and rising up. There it gradually cools down and sinks down again. The process is repeated many times, allowing you to create a comfortable temperature in the room. If necessary, fans can be used to speed up natural convection.

The design features of convectors determine their main disadvantages, including uneven heating of the air. The temperature at the floor itself remains lower than under the ceiling, which, however, is also characteristic of water heating. Another “minus” is that circulating flows raise dust, which is inevitably present in every home. Today, models are produced that are practically devoid of this drawback.

Wall or floor version?

Heating can be carried out using different models of convectors. There are two main types of devices:

• Wall structures. They differ in height, which averages 45 cm, and in the method of attachment. They can either be installed directly on the floor or fixed to the wall using a special device.
• Floor. Narrow long appliances, which are usually installed under low-lying windows, stained-glass windows and around baseboards. Despite the lower power than wall convectors, they will need much less time to heat up the room.

Both types of devices are equipped with thermostats, which can be either built-in or remote. Designs are also produced that do not burn oxygen in the room and do not dry out the air.

The wall model of the convector is mounted on the wall using special fasteners

Floor models of electric convectors are installed on the floor, and not inside it, like their water counterparts. Therefore, they can be installed already at the end of the repair.

Calculation of the required number of convectors for heating

The number and power of the devices necessary to equip the heating of a country house with electricity are calculated based on the volume of the room in which they will be installed.

First, the average value of the power required for heating 1 cubic meter is selected. Room averages:

• with good thermal insulation that meets the energy saving standards of the Scandinavian countries - 20 W per cubic meter. m;
• with insulated ceilings, walls and double-glazed windows - 30 W per cubic meter. m;
• with insufficient insulation - 40 watts per cubic meter. m;
• with poor insulation - 50 watts per cubic meter. m.

Based on these values, the power required to heat the room is determined and the required number of devices for heating is selected.

It is very important to do the calculations correctly. Practice shows that even electric wooden house heating It is absolutely safe provided that the equipment is properly selected and its high-quality installation. Convectors are an effective, but far from the only option for space heating devices powered by electricity.

A variety of electrical home heating systems make it possible to choose the most suitable option that will ensure efficient and safe heating of your home.

Benefits of convector heating

Among the main advantages of convector heating, as the reviews show, the following can be distinguished:

• High level of safety during the operation of the equipment.The best heating convectors are equipped with a special protective casing that does not heat up to such a high temperature as the device itself. In addition, there is such a function as automatic shutdown when heated.
• The devices are equipped with autonomous temperature control. Thanks to the sensors that this equipment is equipped with, it is possible to regulate the temperature and set the most comfortable and optimal temperature regime. In addition, the equipment can be left unattended for a long time.

Convector device

• Humidity can be adjusted. Convection heating at home is not able to dry the air. By means of such devices, you can create the most suitable microclimate in the room.
• High level of moisture resistance. Devices for convector heating systems, due to their design features, are protected from moisture ingress. In addition, the materials from which the equipment is made have excellent resistance to corrosive effects.
• Beautiful appearance. Modern convection heating of a private house has an aesthetic appearance and the equipment can fit into the interior of any home.
• Long service life. Such devices will be able to serve you faithfully for many years.
• Affordable cost of a heating convector. Due to the large number of manufacturers of this equipment, the price for it is quite acceptable.

Selection according to your needs

Convectors have different completeness. Equipped with control panel, mechanical and electronic thermostat. In small-sized structures, protection against tipping over is provided. The perforated vents are positioned differently for air circulation.

The devices differ significantly in weight and dimensions.They are manufactured with different degrees of housing protection (IP) - for dry and wet rooms. The reliability and efficiency of the equipment has been appreciated by many private property owners. A wide range of models allows you to choose the right convector according to your needs.

Using convector heating at home

The operation of the unit consists in passing cold air masses through the heating element and increasing the temperature. Further, the air simply rises, warming the atmosphere in the room. Some types of appliances are equipped with fans to help improve air circulation in the room and speed up the heating process.

To increase the air temperature, a high-resistance ceramic heating element is used, hidden in a metal case.

Installing an electric convector on walls or floors. If necessary, the device can be easily moved within the length of the wire, for which special wheels are provided on the bottom panel.

Large convectors are located on the walls and floor, and small convectors are located near the baseboard.

Types of convectors with electrical connection:

• wall appliances;
• floor convectors;
• built-in devices in floor niches;
• plinth units.

Wall types usually have a lot of power. For their location, a place is carefully chosen, since it is problematic to outweigh them in case of unsuccessful placement. Very efficient and do not take up much usable floor space. The disadvantages include the fact that the air enters the middle of the height of the room and rises, the floor in this case remains cold, so they are placed on the wall as low as possible.

Floor convectors for heating houses usually perform low power, but due to their low location, they heat the air in the room faster. They move well in different parts of the room.

Floor convectors for the house recently very much in demand for the organization of heating. They are mobile placed in special niches that are prepared in advance. Making these changes requires additional funds, but the heating of the room occurs quickly and saves space in small rooms.

Skirting convectors produce little power, but by buying, for example, two of them, you can warm up the room most fully. They are installed near the plinth, and their height varies up to 15–20 cm. Feedback on the use of this type of convectors is positive.

Device and principle of operation

Electric convectors for a private house is chosen for its high energy efficiency and ease of commissioning. They do not require a connection to the boiler, laying a pipeline system. Everything you need is already included in the package. But if you use a convector for main heating in winter, you will have to accurately calculate the power of the devices for the entire building, since the load on the network has a limit of 5 kW, and if it is exceeded, you can simply be left without light or get a short circuit.

Electric heaters that use the principle of convection in their work are a technique in which air is passed through the lattice base of the device, being exposed to heat.Under the influence of natural physical processes, heated air masses rise. Cold air, being forced out, moves down, and enters the convection cycle. The air exchange process is continuous, and it does not require additional devices such as fans.

The design itself is also simplified as much as possible. It has:

• housing with holes for air inlet and outlet;
• a heating element that maintains the required temperature;
• control unit, which may include a thermostat;
• optionally - a fan to accelerate convection, which is needed to quickly heat the room;
• output for the power cord responsible for connecting to the household power supply.

This turns out to be quite enough to ensure efficient heating of small rooms using exclusively electric energy.

Electric convector device

All this is combined in one frame, which has a decorative finish and options for mounting on the floor and on the wall.

The body is equipped with grille windows for supplying warm air into the room, and the body skin is made with air gaps that do not allow getting burned when touching the body.

The front part of the body is used for the location of the buttons for controlling the convector's actions. Electric convectors with a fan are noisy and cannot boast of quiet operation.

Our old dwelling did not meet the power requirements for connecting powerful electrical appliances. It was unprofitable to change the wiring, so we decided to use convector heating in a small house outside the city. We do not permanently live there, and installing a boiler is just an unnecessary waste.

Heating with convectors has led to the fact that we advise all our friends to summer residents to use it in the house. The room always heats up quickly, and we can not say any complaints.

Possibilities of heating a house with electricity

Today, people are increasingly interested in electric heating of a country house. The options and prices of such heating systems are different - you can buy an expensive boiler, or you can get by with just a few convectors.

If we are talking about heating a dwelling, then first of all we mean liquid fuel - gas, less often - diesel fuel. Gas is indeed a very profitable fuel, because it effectively heats the house and is inexpensive. There are also solid fuel boilers on the market that run on coal or ordinary wood, for some, only one stove is enough.

But there is such a problem that not all villages are connected to the central gas supply. You also, for certain reasons, do not want to use solid fuel for heating. The way out of this situation is heating with electricity.

This type of heating system has a very important advantage - it is an environmentally friendly method of heating, because during operation no smoke and various toxic substances are emitted. But there is also a minus - such a system is the most expensive to operate.

It is worth noting that manufacturers are actively working on the disadvantage, and modern equipment is no longer so voracious.

If you still decide to switch to electric heating, then you need to consider that all rooms must be equipped with high-quality thermal insulation. You also need to have ventilation in the room, so that everything is ventilated, and the heat produced is distributed throughout the house.

Infrared panels and heaters

Heating a house with electricity using infrared heaters is not so popular, but still used quite often. As the name implies, such heaters transfer most of the heat in the form of radiation. Could it be infrared rays? different spectrum. According to their design, they can be performed in different versions. These can be panels for wall mounting, similar in shape to a convector, or infrared emitters with special lamps.

In terms of convenience, infrared systems are inferior to convectors in the sense that they heat objects more. Infrared rays practically do not heat the air in the room. Most of the heat is transferred to objects and people in the room. This is convenient for saving, but it is not always comfortable for people. This is especially true for infrared emitters with a lamp.

main parameters

Having figured out what convector heating is, you should arm yourself with general information about its technical characteristics. Power of electric convectors is in the range of 0.8 -3 kW, weight - from 3 to 9 kilograms.

Electric convectors currently on sale are divided into three groups:

• High (450-670 mm).
• Medium (up to 330 mm).
• Narrow (for skirting boards), 140-200 mm high.

Due to their parameters, high-type heaters are able to provide a significant level of convection. Skirting models are equipped with less powerful heating elements. To maintain the proper level of efficiency, they are given a large length (up to 2.5 m).

Which option do we recommend?

Most often, residents of the house are encouraged to use electric heating by two facts: the lack of gas with the reluctance to burn with coal and the financial component.

The surest option would be to make a full-fledged water heating and use an electric boiler. If there are any power outages, then you can safely resort to an alternative option.

If you need to provide heat for one or two rooms, then it makes no sense to build a full-fledged boiler room. In this case, we would buy ordinary electric convectors and use them.

Electric heating of a country house - all options

When it is possible to implement electric heating of a country house, the options can be very different. They will differ not only in terms of the heat generators used, but also in the very way of supplying heat to the premises of your country house.

In order to be able to really organize the electric heating of a country house, the options for which are presented here, you only need one indicator. This is the allocated electrical power for your site.

Depending on how much power you have allocated, you can use different types of electric heat generators.

Calculation of power consumption

water heater

Calculation of the power consumption of a water heater (boiler) with a capacity of 2 kW, if you turn it on for 4 hours a day (in the morning and in the evening for 2 hours):

• 2 kilowatts multiplied by 4 hours is 8 kWh. This is the cost for 1 day;
• 8 kWh multiplied by 30 days is 240 kWh. This is an expense per month;
• We multiply 240 by 3 rubles (how much does 1 kWh cost you), we get 720 rubles.So many rubles are paid for electricity for a two-kilowatt boiler if it works 4 hours a day. You plug in your numbers and count.

Lamp

For example, a 50 watt light bulb burns 6 hours a day. It consumes 0.05 kW (50 W) of electricity per hour. For 6 hours - 0.05 kW 6 h = 0.3 kWh. And for a month when burning 6 hours every day - 0.05 kW 6 hours 30 days = 9 kWh.

Let's say the cost of 1 kWh is 3 rubles. Thus, in a month our light bulb will spend electricity for 27 rubles.

The heating system of a private country house with an electric boiler: which electric boiler to choose, and what are

Unfortunately, gas pipelines have not been built in all regions of our country. In this situation, they usually install an autonomous steam-water heating system for a private house with an electric boiler. The once-through boiler is a cylindrical tube with heating element inside. Which electric boiler to choose to solve your urgent tasks of providing thermal energy? To do this, you must first understand what electric boilers are and how they differ fundamentally from each other. After studying all the information offered, you can make the right decision regarding which electric boiler to choose for the house and its heating.

The heat carrier in this case is water or non-freezing liquid, the method of heating of which may be different. In some systems, a tubular electric heater with a high resistance inner conductor, the so-called boiler, is built in, which heats running water. The system starts working as soon as it is turned on.

Heating a country house with an electric boiler can be used in conjunction with gas or solid fuel, including them during the day, and an electric boiler at night. Indeed, in the dark, the tariff for electricity is lower, you just need to install a two-tariff meter.

There is another type of boilers powered by electricity - electrode, or ionic. Water in such an apparatus is heated due to the fact that ions move between the electrodes. Voltage is applied to the electrodes located at a certain distance from each other and immersed in the heat-transfer fluid. Molecules are split into positive and negatively charged ions, which tend, respectively, to the positive or negative electrodes. During this process, thermal energy is released, which is transferred to the coolant. Thus, the water is heated.

Unlike the previous type, the electrode boiler heats up gradually. Electricity consumption will also depend on the volumes consumed, the set temperature and the total volume of the heating system.

The boiler has a cylindrical shape, adjusts itself to the required power consumption and can turn off if the temperature rises above the temperature set for the batteries or the air in the room. In the event of a short circuit, liquid leakage or overheating, the device switches itself off.

Depending on the power, such a boiler is able to supply coolant for 4-40 radiators in the house. Such equipment can be equipped with an automatic temperature controller and an electrical control panel. They control the room temperature and power consumption.

The power of the device is always chosen with a margin, and the power of the mains is also taken into account. If 3 kW is enough to heat the house, a 4-5 kW boiler should be chosen.

Of the imported brands of electric boilers, German Bosch, Eleko and Protherm, Polish Kospel, and Czech Dakon can be distinguished:

The heating system also includes a heating network, where there is a process of natural or forced (with the help of a pump) circulation of the coolant, which moves through the pipes and fills the batteries. The liquid that has given off heat to the radiators again enters the boiler, where it is heated.

It may seem that heating a house with electricity is a costly affair. However, electric heating has its advantages. As a rule, such a system is fully automated and equipped with a remote control. For the installation of an electric boiler room, a chimney and a separate room are not required. Thermostatic valves built into the heating system regulate the heating of the batteries and save energy consumption.
