Cheap electric heating of a private house. How to save on heating a country private house

29.04.2018

People living in high-rise buildings in large cities have long been accustomed to a centralized heating system. Since it is not possible to find out exactly how much heat is spent on each apartment, then payment is collected from everyone according to certain standards established by public utilities. Those who live in private houses are more fortunate, they can choose the most profitable and most economical heating for themselves.

Types of heating and the possibility of saving

Consider several types of heating:

Electricity. At present, this is the most expensive way of heating and it is difficult to define it as economical heating. Therefore, it is most often used as an additional heat source.
Gas. Heating on gas is the cheapest and most economical. If there is a gas main nearby, be sure to choose this one economical heating.
Solid fuel - peat fuel briquettes. Most often used where there is no gas pipeline.
Liquid fuels. Boilers for space heating can run on diesel fuel and are another type of fuel included in the category of economical heating.
This is the most reliable and proven method of heating for centuries. If you put a fireplace in the house, then you can not only heat the room, but also enjoy watching the burning fire on cold blizzard evenings, creating a cozy romantic atmosphere in the house. Of course, there are also disadvantages. The most important is a great fire hazard, as well as the high cost of firewood. True, it is much cheaper than using electric heaters.
Heating with coal. It is very common in the CIS countries so far.

Alternative heat sources

Progress does not stand still and every year there are more and more different economical heating systems and not very economical ones. They can replace the usual traditional types of home heating, as well as save money.

For example, the new skirting system offers mini radiators that are placed under the skirting boards, thereby creating a microclimate in the room that has a beneficial effect and maintains heat.

This system is interesting in that it does not heat the air, but walls, furniture, that is, surfaces. This is economy heating, and such a system will save up to 30% of electricity. The warm skirting system works by heating water using heating elements. For example, a 12 meter skirting board will require only four liters of water.

Modern economical heating systems used to heat private houses

Infrared heating systems. The method is very convenient, but laborious, there is no need to lay pipes and install boilers, the savings are about 60%, if we take into account the usual payment for heating.

Air systems. If you ask the question which heating is more economical, then, in principle, you can cite as an example and air systems. This is quite economical, gas air heaters and pipes are used, through which heat enters the house. They have many benefits. In order to prevent dust from rising along with the heated air, there are filters that purify the air. energy saving heating installation. Converts electricity into heat, but does not consume much electricity.
Infrared film for heating. New from foreign manufacturers. It is used as a floor covering, it is quite economical do-it-yourself heating. But you need to take into account that you can’t lay or put anything on this film, even carpets.

Solar panels. For those who live in the sunny parts of our country, and the world, this is just an ideal option. It will save a lot of money, you will not need to pay for hot water every month, you will have it all year round. You will not worry about turning off the heating or hot water. And also you will always have electricity. Now it has become popular to install solar panels on the roofs of houses, they can also serve as an additional source of power supply, if the electricity suddenly turns off, they will help support the operation of heaters, boilers, it will be possible to watch TV, use various household appliances, charge your phone and much more. You will be practically independent both from suppliers of hot water and heating, and from power engineers, which will significantly save you money, nerves and time, and make life easier.

Cosy warm house- the dream, probably, of every person. Today, most people prefer to settle in private homes, because it has many advantages. But how to make your home the most comfortable, everyone decides in their own way. And, probably, initially it is worth dealing with the amount of heat and light.

What heating is better for a private house

There are several ways to heat country house. Each of them has its pros and cons, principles of operation, requires certain costs. The choice of a particular type of heating depends on many factors. For example, from the presence of a fireplace or stove in the house, electricity, the availability of materials such as gas, fuel, firewood or coal.

Depending on this, the following types of home heating are distinguished:

Air;
Electric;
Water.

The air heating system passes air through a special device - a heat exchanger, after which the heated air is evenly distributed throughout the room. This type of heating is expensive and requires a lot of space. However, it provides fast heating of the house.

Electric heating is based on the conversion of electricity into heat.

This type is environmentally friendly and easy to install and use, but, despite this, it significantly increases energy costs and forces you to constantly ventilate the room, as oxygen is burned. Water heating It is based on the circulation of liquid through pipes, which provides heating of the room. Such a system can be mounted without the help of specialists, however, during frost when the system is turned off, the water can freeze and break the pipes.

The most popular and economical way of heating is electric. It will be discussed further.

Home heating with electricity: cheap or expensive

Exists great amount heating methods. But, unfortunately, not all of them can be used in your own home.

Electric heating is the cheapest and most convenient option:

A minimum of effort is spent on installing such heating;
Installation of the system does not require adjusting to any season;
The heating system is very compact and does not require building additional room under the boiler room;
There is no need to provide maintenance;
The cost of using such a system depends on the degree of work and the level of temperature;
The electric heating system is the most environmentally friendly.

In this way, electric heating does not require special physical and cash costs and is most common in private homes.

Types of electric heating systems

Heating electrical systems are built on converting electricity into heat. The methods of such a transformation differ, and the main types of such systems are based on this. However, they all have one minus, unlike gas - the cost of their use is high, since they are based on electricity.

Among them are:

Electric boilers;
Electric convectors;
Heaters based on the use of infrared rays;
Underfloor heating powered by electricity;
Fan heaters.

Electric boilers operate on the basis of heating the liquid in the heating circuit, which is connected to them. Electric convectors also use heating elements. Only in this case, electricity does not pass through the liquid. Heating is carried out by heating the aluminum or steel housing and the air that is inside this housing. Hot air rises, changing places with cold air. With the help of such circulation, the room is also heated.

Electric heating is the most economical: without a boiler

What is the most economical way? Convectors do not take up much space and can be placed on the wall, on the floor, be built-in and external. They quickly warm up the air and accurately perform the set tasks. The only downside is that one convector will not be enough to heat the whole house.

Infrared heaters convert electricity into infrared rays that can heat any object. They can take the form of rectangles embedded in the floor or wall, or mounted on a stand. Such a heating system heats the air only in a certain area of \u200b\u200bthe room. In order to heat throughout the house, you need to install a large number of such devices. On the one hand, they are cheap to use, but their quantity increases the cost of the outlay.

Infrared heaters are economical because individual temperature conditions can be set in different areas of the house. Therefore, these heaters are on average 35% more economical than boilers. Electric underfloor heating is installed under the tiles and may not be the main heating system.

Benefits of underfloor heating:

You can easily and accurately regulate the temperature in electric underfloor heating;
Electric underfloor heating does not need to be filled with new screeds, which require additional costs and put extra pressure on the floors;
Due to the ease of installation, electric underfloor heating can be equipped both in a private house and in a multi-storey one.

The disadvantages of such a system are only the cost of electricity. But, on the other hand, if the electric floor heating is still not the main one, then this drawback can be crossed out. Fan heaters (heater, not battery) are not the main heating system. They have a quick effect only in small rooms, but at the same time they use a large amount of electricity, due to which they greatly increase the cost of expenses. Electric batteries are not bad heaters.

Economical electric boilers: options

Boilers are divided into those based on heaters - heating elements - and electrode.

The work of the heater is that they heat running water and distribute it throughout the system. Special pumps are often installed with heaters to help circulate fluid through the system. Usually there are 3 or 4 heating elements in the boiler, which can work simultaneously or one at a time - it all depends on the temperature level.

The power of boilers for electric heating also varies. There are models that operate on a single-phase or three-phase network. The electrode boiler relies on the fact that electricity passes through the liquid from electrode to electrode. Instead of water, an antifreeze liquid is used here.

Advantages of electric boilers:

Easy to install and adjust;
Do not take up much space;
Accurately and quickly adjust the temperature level;
Their work does not create noise;
Relatively low cost and economical maintenance.

Cons of electric boilers: high energy costs, with prolonged use of heating elements, heaters become covered with scale and stop working, in the absence of water, heating elements burn out. Often, boilers do not cope with their tasks and cannot heat the whole house, that is, they slowly heat the house. The operation of the boilers depends entirely on the power of the electrical network. Correct schemes and high-quality batteries for a cottage allow you to heat the house inexpensively. A homemade device is quite possible.

The most economical electric heating and electrical appliances

The most economical and easy to use is the electric convector system. They consist of an aluminum or steel body, which heats the air both from the outside and from the inside. Warm air gives way to cold air, and thus the entire room is heated.

Advantages of using convectors:

The convector is the most efficient heating system. Due to the small size of the heating elements, the air heats up faster, evenly distributed throughout the room.
This is the highest quality type of heating, as it does not waste electricity, completely converting it into heat. This is also the reason for its economy.
Convectors are easily regulated and do not heat up above 100 ºС. Many models have a security system that turns off the device if air access is closed.
Such a heating system is quite simple to install and use. All you need to do after purchase is to install it on a wall or on a stand and plug it in.
Convectors are much cheaper than electric boilers.
Since one convector will not be enough to heat the whole house, you need to purchase more devices. However, this can be done gradually, depending on the need or the availability of funds.
Such a heating system does not respond to possible power surges and continues to work properly.

The choice of a convector depends, first of all, on the estimated price. However, it is best to buy the device from leading manufacturers, since the issue here is about home security. It is important to pay attention to the restart function after turning off the device. If in this case the convector requires human intervention, then this will create some problems in its use, including the risk of great damage from freezing the house. Efficient and profitable alternative heating according to new technologies.

Installation of electric heating of a private house

Installing an electric heating system is very easy. Therefore, you can do it yourself. This will save you money as you don't have to call a professional.

Installation consists of three stages:

Planning;
Installation;
Launch.

At the beginning, it is necessary to prepare a heating scheme and appliances, taking into account the way it is used. In order to carry out an economical heat calculation, choose an electric boiler for a private house, for this you can call a specialist, or use ready-made programs.

Further, shields are equipped with separate machines for each room and the wiring is bred. You need to consider how many boilers and other equipment you need to purchase. You will need automation, ceramic or other pipes. An electric battery that will heat, with an electricity consumption like a light bulb, is everyone's dream. To save some fuel, modular energy-saving gas elements for the premises of country houses will help.

After the electrical wiring is ready, you can proceed with the installation of equipment that will help heat the room (energy or economy radiators). It is important to pay attention to the temperature regime. At first, the device will work hard. So the room warms up very quickly. And then the system will switch to normal mode and will turn on to maintain the set temperature level, like a drip device.

However, using only electric heating can cost a pretty penny. Therefore, other means of heating the house should be used to increase the comfort of living.

Methods for additional thermal insulation:

Insulation of loggias, balconies and verandas will close the penetration of cold street air into the house. Thus, heating the house will be much more efficient.
Replacing old windows with plastic ones. This will eliminate the occurrence of drafts, which is also good for heating in bad weather. If it is not possible to install new windows, then you can insulate the old ones. To do this, it is necessary to coat the places between the frame and the opening with sealant and seal with electrical tape.
By the same principle, old doors are replaced with new ones.
You can insulate the walls both outside and inside. Internal insulation reduces the size of the room, so experts recommend insulating the walls from the outside. For this, heat insulators are used.
Ceiling insulation is most often carried out in the attic. In this case, mats are used, under which a vapor barrier is placed, and a hydrobarrier is placed on the mats.
You should pay attention to the insulation of the floor. This is important because most often the floor warms up poorly, which causes some discomfort.

According to the laws of physics, warm air rises, giving way to cold air. Therefore, it is important to insulate the roof so that the heated air does not leave the house at all. The method of roof insulation depends on its type. If it is a pitched roof, then the insulation is done inside the house using mineral wool. If the roof is flat, then rigid materials are used from the outside, which are not subjected to various negative influences for them. Homemade products (convection, autonomous, innovative heating in an apartment) are also possible, the panels will save money, but the equipment should be thought through thoroughly.

Heating residential premises with the help of electricity is a modern, environmentally safe and convenient type of heating an apartment or a private house. The main factor that prevents the widespread use of this heating method is the rather high cost of the energy carrier and the mandatory modernization of old electrical wiring.

Naturally, today gas remains the most efficient type of heating. But what to do if there is no central gas pipeline in the summer cottage or in the village to which you can connect? Properly use the energy resources that are available - electricity or solid fuel. At the same time, the latter fuel, despite its availability, requires special storage conditions.

Why is electric heating popular?

The reasons that make a person opt for an electric energy carrier for heating a house are as follows:

in the private or suburban residential sector simply no centralized gas supply;
cost of electrical equipment for heating residential premises is an order of magnitude lower than gas analogues;
Huge range of heating systems using electricity as energy resources;
P ease of use and installation of electric heating.

However, not everything is as perfect as it might seem at first glance - the electric space heating system requires powerful electrical wiring, the parameters of which will depend on the area of \u200b\u200bthe heated house. If the room was built without taking into account the installation of an electric heating system, it is imperative that the power line be upgraded.

The main types of electric heating systems

Heating an apartment is always associated with old cast-iron radiators under the windowsills and a feeling of discomfort, since often the heat supplied from the central heating network not enough to create an optimal indoor climate in severe winter frosts. However, the use of electrical energy made it possible to erase the prevailing stereotypes through the use of the following heat sources:

electric heating boilers;
convection heaters;
infrared heat sources;
underfloor heating powered by electricity.

But in order to figure out which electric heating is the most economical, you need to study all the features of each individual method of heating houses.

Home heating with an electric boiler

By its principle, such a heating system is similar to a centralized heat supply with the only distinguishing feature, which is in the placement of a heat source indoors. Thanks to this, the homeowner gets the opportunity to adjust the temperature in a wide range.

Such a heating system is much more economical than a central heating supply. Although it was not spared by the common disadvantages of water heating:

electric heating boiler provides for the presence of piping to the batteries;
the cost of the boiler, although less than the gas counterpart, is still quite large;
if using a system with natural circulation coolant, then you need to observe the slope of the pipes during installation and monitor the absence of air pockets.

In addition, if we take into account the ever-increasing cost of energy resources, an electric boiler in a home heating system can hardly be called the most economical heating option. Plus, scale is deposited on the main heating elements, which leads to a sharp decrease in the efficiency of the boiler.

Convection type heater

The electric convector can rightfully be attributed to one of the progressive heating devices. This area of space heating is presented in the widest range of forms, power indicators and methods of fixing electric heaters. The consumer is given the opportunity to choose a miniature wall-mounted product or a high-power floor electric convector. There is no need for any preparation to install the device.

If we consider the principle of operation of the convector, then it can be both using a coolant and air. In the case of using liquid heating occurs due to tubular heating elements, after which the thermal energy is distributed along the fins of the device and heats the room. To speed up heat transfer, some convector models are additionally equipped with a fan. Air units provide direct heating of metal fins with further heat transfer to the environment.

The main advantage of such a heater is its ease of installation, which is limited to mounting two brackets into the wall if it is a wall-mounted convector. In turn, the installation of all other models of convection-type electric heaters comes down to the banal inclusion of the device in a socket.

Underfloor heating system

It is difficult to find a person who has never heard of warm floors. Based on the name, this floor heating system b. At the same time, the main features of such heating devices the following criteria can be included:

the complexity of the installation work, due to the installation of the heating element in the floor;
high level of efficiency - temperature indicators practically do not differ anywhere in the room.

If we consider the types of underfloor heating, then usually these are electrical cables with a high coefficient of resistance or film heating elements, which are foil metal.

Electric heater with infrared heat source

Recently, low-temperature infrared panels with a wall mounting method have become very popular. A feature of such heating is not the radiation of heat by the device, but heating of all surfaces that fall into the zone of action of infrared radiation. In addition, such heaters operating on electricity have the following advantages:

Infrared panel in most cases is used as a zonal heat source. Simply put, infrared rays are directly directed at a person and the area in which he is located. Thanks to this, a comfortable temperature is created in a single part of the room. At the same time, the remaining zones in the room have a lower temperature regime.

What is better not to use in heating with electricity?

Despite the fact that most heating electrical devices are economical, among them there are models that not advisable to use in everyday life due to high energy consumption. At the top of the ranking of losers is located oil radiator. Such devices have high power, which simply devours electrical energy, which affects utility bills.

In addition to the fact that such heaters consume a huge amount of electricity, they are inefficient and warm the room very slowly. For example, and infrared emitter with much lower power consumption heats up the room many times faster the same area. At the same time, due to the peculiarity of placing such a device on the ceiling or wall, it does not occupy usable space in the room, unlike an oil cooler.

Another less recommended option for space heating is a fan heater. Besides the fact that it burns oxygen and drives dust around the room, the fan heater makes an annoying noise. At the same time, they cannot be attributed to economical and efficient heaters, despite the high power of the device.

The most economical electric heating

The question of which is the most economical electric heating does not have an exact answer. Someone will give preference electric boilers capable of heating large areas. Some prefer to use infrared wall panels that create a comfortable microclimate in a certain area, someone likes an electric convector, and some create a system of warm floors in the house.

The use of electric energy for heating residential premises is a good, although not the most economical alternative to gas. Very often, due to the lack of a central gas pipeline near the house, electric heating is the only option to keep warm in winter. But before the homeowner makes the final choice, he needs to learn how to understand design features and efficiency different types electric heating of residential premises.

On the map of our homeland there are places where gas supply is not available. In this case, use alternative sources heat. What are the ways and options for heating a country house without gas?

Furnaces

Firewood and coal effective method heating for the countryside. They have long been used to heat village houses. The advantages of the option are affordable raw materials at low prices. Disadvantages - the need to regularly maintain the fire, free place for storing firewood, the need to purchase and install a stove, boiler, and other consumables.

Electric heating

Electric heating has a number of advantages and disadvantages. Economical heating of a private house without gas is possible only with proper design and installation of equipment.

Note. To determine how effective the technology is for a particular facility, it is necessary to carry out preliminary calculations of heating and resource consumption in accordance with SNiP standards.

The advantages of the method include: minimal costs for installing appliances, no chimney and boiler room are needed. When heating rooms in this way, carbon monoxide is not formed, there is no risk of harmful emissions if the system breaks down. Despite all the advantages of the technology, it cannot be said that the method is the best way to heat a house without gas.

What is known about the cons. Electricity costs vary by region. The option may not be economically viable. An important drawback is the complete dependence on power sources. When the electricity goes out, the system stops heating the house.

Alternative energy sources

Heat pump

The equipment allows to receive low-grade heat from air, soil, rocks and reservoirs. The technology has been used in Europe for decades.

The advantages of the option are free heat sources. The use of technology allows to reduce heating costs. For every 2-3 kW of electricity spent on the operation of a heat pump, up to 6 kW of thermal energy is released. Savings are especially relevant, with the regular increase in tariffs, which is observed in the housing and communal services industry.

And yet, it cannot be said that this is the best option for how to heat a house without gas and electricity. An important drawback of the technology is the high cost of equipment. The cost of a heat pump is from 100 to 400 thousand rubles. Another unpleasant feature of the equipment is a decrease in efficiency at temperatures below -10º C. In addition, the area for feeding the equipment cannot be planted with plants, and its area should be several times more sizes the building itself.

Solar collectors

The equipment works autonomously. This is a big advantage over dependent technologies. Collector converts to thermal energy sunny. This is one of the best ways to heat your home cheaply without gas. During the operation of the equipment you will not have to pay.

Cons of technology

1. high cost of the collector $500-1000;
2. water heating only up to 60º C;
3. periodic replacement of the storage tank;
4. failure to provide 100% heat.

Note. A complete transition to heating a house without gas and electricity using a collector is impossible. The equipment is used as an additional source of heat to reduce heating costs by 40-60%. With the onset of cold weather or in windy weather, you will additionally need a water pump to disperse the water in the pipes. When the climate worsens, the collector stops working at full capacity.

Water heating

Popular technology allows you to effectively heat the premises of a private house. Are you considering how to heat a house if there is no gas? Take a look at hot water. Heating bills can turn out to be small, however, you will have to spend money on installing equipment, pipes, batteries, a tank, a pump. The technology allows the use of several energy sources:

The disadvantage of panels is expensive fuel (electricity).

How to save on heating?

A simple solution will significantly reduce heat loss. We are talking about high-quality insulation of walls, door blocks and window openings. This will reduce heat costs by up to 50%.

Of all the ways to heat a house, the most economical is gas. In places where there are no appropriate communications, other options are chosen. By clicking on it, readers will find out how cheaper and more profitable it is to heat a house with gas or electricity. Today it is economical to heat cottages with coal. Fuel is available. It is inexpensive. There are automated coal-fired equipment for sale. Its price is 1.5-2 times cheaper than heat generators.

What is the best way to heat a house if there is no gas? If the room is used as temporary housing, on short visits, a heater can be used. Among famous models more often choose oil specimens. A fairly economical and safe option is an infrared heater. The method is suitable for heating one room, not the whole house.

For each residential building, whether it is a large multi-apartment building, or we are talking about a private household of one and two-story type, the organization of efficient heating is of great importance. There are a lot of existing heating options today, however, due to technical capabilities, not every house can be connected to gas. It is not always possible to supply solid fuel or liquid fuel boilers with the required amount of fuel. In such situations, home heating will become electricity.

Already at the stage of designing an electric heating system, it can be concluded that this method of heating will be much cheaper and more economical. Especially if we compare the speed of installation of electrical equipment with the laying and installation of heating systems of other types. Economic efficiency in some cases is a decisive factor when choosing a heating system. Despite the fact that today electricity is constantly becoming more expensive, new technologies allow the use of electric heaters with high efficiency.

The concept of electric heating should be understood as a fairly wide range of technical means and capabilities. Electricity is a unique type of artificially produced energy that can be successfully used for domestic purposes. Electric heating can be of two types:

with an intermediate coolant;
with direct heat transfer.

In the first case, we are talking about a system based on an electric boiler that heats up the coolant and distributes it through the pipeline system. In the second case, we are talking about independent heating elements and appliances powered by an electrical network. To heat the house, like any other room, convectors, thermal electric fans, spiral and infrared heaters. This method of heating is much simpler from a technical point of view. The only negative is a significant overspending of electricity, which will have to be paid. A separate discussion deserves a warm floor, a technology thanks to which you can truly achieve comfort in heating residential premises.

If we consider the ratio of opportunities and benefits obtained from the use of electric heating with other types of heating, then electricity will look preferable. Main advantage electrical systems heating - high efficiency. Other positive points include:

durability of operating systems;
ease of maintenance and operation;
reasonable costs for the purchase of equipment, installation and connection.
silent operation and high level of safety of modern electric heating installations;
lack of permits for the installation of electric heating systems.

The economic effect is achieved through the installation of thermostats on electric heaters, due to which automatic switching on and off of the power supply occurs.

Do not forget about heating apartments with electricity.

The listed pluses are leveled by one minus. To install sufficiently powerful electrical heating appliances in the house, an electric boiler, it will be necessary to additionally equip the residential building with electrical distribution devices and devices.

Important! Wiring in the house must be able to withstand significant loads, especially in the cold season. In addition to everything, the electrical switchboard must be equipped with a multi-tariff meter, which allows intensive use of the nightly cheap tariff. The main task in the installation of electric heating systems is to optimize the operation of the entire complex.

Electric boiler or convector - what's the difference? What to pay attention to?

From a technological point of view, an electric boiler is the most profitable in terms of price-quality ratio. Before making a purchase, you should carefully study the technical capabilities and characteristics of the models on the market. Assessing the capabilities of the boiler, it is necessary to take into account the amount of work that new equipment has to cope with. In order to heat a house with an area of 150 m 2, according to approximate calculations, at least 150 kW of electricity per day will be required. Not every boiler is able to cope with such a volume, and not all power lines are able to withstand such a load.

The boiler is connected to the usual standard water heating system, heating the coolant during its operation.

Each model is equipped, which allows residents to independently choose the temperature regime. Automation itself regulates the power of the boiler based on the specified parameters, without requiring human intervention, providing the necessary savings in electricity. The water supply is also regulated using the built-in pump, so there is no reason to worry about the normal pressure in the system. Additional equipment, which is equipped with most today modern models electric boilers, increases the functionality of the system and aims to reduce electricity consumption, saving you money.

In the process of optimizing the operation of the heating system, it is important to consider heat loss that are characteristic of the room. This indicator depends directly on the thickness of the walls, the presence of insulation, the number of doors and window openings. The main heat loss occurs through windows and doors.

Last but not least, the heating efficiency depends on the parameters of the selected electric boiler model. There are classic boilers with heating elements, as well as more efficient modern options- induction and electrode (ionic). Moreover, all of them have an efficiency of 90%.

For reference: Often, manufacturers in the accompanying documents for the goods write the efficiency of the model - 95-98%. The figures look impressive, although in reality the figures are much lower, in the range of 90-92%.

With the simultaneous use of a large number of electrical household appliances, the temperature of the coolant in the electric heating system can be reduced, saving on a balanced consumption of electricity. Each specific case provides different options for savings, in contrast to the use of other heating systems. For example, for heating a country house with an area of 50 m 2, an electric boiler with a capacity of 3 kW is required. Having the necessary numbers at hand, it is not at all difficult to calculate the number of kilowatts that will be consumed during the month with the continuous operation of the boiler.

For instance:

house area - 50 m 2;
electric boiler - power 3 kW;

We do arithmetic calculations using the following formula: 3x24x30, where 24 is the number of hours in a day, 30 is the number of days in a month. We get 2160 kW per month with the boiler running, and now we multiply this figure by the electricity tariff that is set in your region.

All calculations are approximate. The real amount of electricity costs will be visible only after some time. Only then can you make an independent adjustment of the operation of the heating system in the house, determine the appropriateness of using other electrical appliances in everyday life.

If you need to organize heating in your own house without laying highways and installing numerous equipment, you can get by with convectors. Unlike electric water heating in convectors, the basic principle of operation is the convection of warm air. Due to the operation of the heating elements, the ambient air is heated. The system is almost completely self-contained, compact and able to quickly heat up small interior spaces.

Convectors are equipped with temperature controllers, with which you can set the optimal heating parameters. The presence of automation provides automatic switching on / off of the device, depending on the temperature regime inside the room. To install heaters of this type, you must have high-quality sockets and reliable wiring.

Convectors can be installed both on walls and on the floor. The cooled air goes down, getting into the field of action of the heating elements, heats up again and rises up, and so on in a vicious circle. Thus, the process of convection of air masses is achieved. The operating mode of heating convectors is 60-100 0 C. Additionally, the room can be equipped with fans, the operation of which will accelerate the air exchange of the air mass. Despite the apparent simplicity of the design and the elementary principle of operation, the heating of the room with the help of convectors is carried out unevenly. Under the ceiling, the air will be warmer, while cool air masses will be felt below.

In order to achieve savings when using convectors, it is enough to carry out a simple mathematical calculation that allows you to determine the required number of devices for normal space heating. Practice shows that convectors are effective in heating wooden residential and household buildings of a small area. In capital, stone buildings with premises of a large area, it is not advisable to use convectors. Large volumes of air quickly cool down, the time for heating the room by convection of air masses increases significantly. Consequently, the energy consumption of the heating system increases.

Underfloor heating - economical heating of a private house

Electric boiler, convectors are not the only options to equip private house efficient heating system operating from the mains. Underfloor heating, which today has become fashionable to mount in country houses and in apartments it can be a good alternative to any other heating option. From the point of view of physics, a warm floor does not give a noticeable effect in heating residential premises, however, in comparison with the operation of other electric heating devices, thanks to a warm floor, it is possible to reduce energy costs for heating.

The desired effect is achieved through rational distribution of heat. Floors are known to be the coolest part of any room. Thanks to warm floors the coldest part of the room is automatically re-profiled from the cooler to the source of heat energy. The air heated from below over the entire area of \u200b\u200bthe room rises in uniform flows. For residential premises, underfloor heating saves 30-40%, for heating other premises, the savings can be 50% or more.

With the help of temperature controllers, optimal heating parameters are achieved. Having independently determined the temperature regime inside the room, it is really possible to achieve significant savings in energy consumption.

The benefits of underfloor heating are:

an effective way to quickly warm up the premises;
acceptable economic indicators;
a comfortable indoor climate is maintained (oxygen is not burned);
simplicity and reliability in operation.

Against the background of the advantages that underfloor heating has, the only drawback of this electric heating option seems insignificant. The problem lies in the complexity of installing such a heating system, associated with the need to reorganize the flooring.

The preliminary calculation of the cost of heating costs in this case is as follows:

The approximate power of standard models used in everyday life is 1.5 kW per 10 m 2. We consider the average daily consumption and get a figure of 360 kW. For rooms of other sizes, calculations are made according to the same principle, the power varies in proportion to the area.

For reference: 360 kW x 2.5 (tariff 2.5 rubles, approximately) we get 900 rubles. And now we multiply the resulting figure by real square meters, for example 50 m 2. As a result, we have a figure of 4500 rubles.

Today, there is a wide range of options to achieve the necessary comfort inside a residential building using electric heating.

Each of us has the right to choose which heating option suits him best. An electric boiler, underfloor heating or electric heaters are options that solve certain problems. You can solve the problem globally by creating a capital heating system or solve issues locally. In any case, you can achieve savings if you rationally equip your house with heating elements, reduce heat loss in the room and optimize the operation of the entire energy system in the house.
