Heating a private house with electricity: advantages and disadvantages. For any residential building, no matter whether it is a large apartment building or a simple household with 1-2 floors, the creation of effective heating will be of great importance. Today there are enough options for heating, but due to the technical nature, not every house can be connected to gas, and it is not always possible to supply it with the required amount of fuel for a solid fuel / liquid fuel boiler. In this case, heating your home with electricity will be the easiest and most profitable way for you.
Already when designing a heating system on electricity, it will be possible to conclude that this method of heating will be more economical and simpler, especially if we compare the installation speed of electrical equipment with the laying and installation of other types of heating systems.
In some cases, efficiency is a decisive factor in choosing a heating system. Despite the fact that now electricity is constantly becoming more expensive, special technologies make it possible to use heating devices efficiently. For this reason, we propose to consider how to choose a heating boiler for a house on electricity and talk about all the connection features.
The concept of "electric heating" should be understood as a wide range of possibilities and technical means. Electrical energy is a unique type of energy obtained by artificial means, and it can be used for domestic purposes.
Electric heating is of two types:
If we talk about an intermediate heat carrier, then this is a system based on an electric boiler, which heats the heat carrier and helps to distribute it through the pipeline system. If we talk about direct heat transfer, then we are talking about independent heating elements / devices that are powered by electricity. Convectors, heat fans, infrared and spiral heaters are often used to heat a home, like other premises.
This heating method is much easier when it comes to the technical side of the issue. The only drawback is that you will have a large waste of electrical energy, which you will have to pay for in any case. Separately, it is worth talking about warm floors - this is a technology due to which it is possible to fully achieve comfort when heating a living space.
When considering the balance of advantages and opportunities that you will receive when using heating a house with electricity with other types of heating, the former will be preferable. The main advantage is high efficiency (efficiency).
Other points include:
An economic effect will be achieved by installing special thermostats on the devices, due to which the power is automatically connected and disconnected from the mains. All of the above advantages are leveled by one single drawback - to install a sufficiently powerful heating device in a private house, as well as an electric boiler, you will need to additionally equip the house with electrical distribution devices and appliances.
Please note that the wiring in the house must be able to withstand heavy loads, especially during the cold season. Also in addition to this, the electrical switchboard should be equipped with a new, multi-tariff meter, which will help to use the night, cheaper tariff correctly. The main task when installing heating systems on electricity is to optimize the operation of the complex as a whole.
From a technological point of view, an electric boiler is the most advantageous option in terms of price-quality ratio ... Before you buy a device for heating, you should carefully study all the characteristics and capabilities of the device and models separately that are presented on the electrical market. When assessing the capabilities of the boiler, one should also take into account the amount of work that the new device will have to cope with.
In order to heat a house with an area of 150 m 2 , you will need at least 150 kW of electrical energy per day. Believe me, not every boiler model will be able to cope with such a volume, and not all electrical transmission lines will be able to withstand such a load. The boiler is connected to a standard water heating system, while heating the coolant in the process.
Each model has its own control unit, which allows the owners to choose a comfortable temperature for them. The use of automation has its own advantages - it itself can regulate the power according to the specified parameters, while no human participation is required, which helps to save electrical energy.
The water supply is regulated in the same way as the built-in pump, so there is no need to worry about normal pressure. When using additional equipment for heating a private house on electricity, you can reduce electricity consumption, which will save you money.
When optimizing the operation of the heating system, it is extremely important to take into account the heat losses that are inherent in the room. This indicator will directly depend on how thick the wall is, as well as whether there is insulation, how many window openings and doors.The main heat loss occurs precisely through doors and windows.
Heating efficiency not least depends on the parameters of the selected boiler model. There are classic boilers in which a heating element is used as a heating element, and there are improved and more modern versions - electrode (i.e. ionic) and induction. Moreover, their efficiency is only 90%.
Note! Most often, manufacturers in the accompanying documentation for the boiler write the efficiency of the model from 95 to 98%. While the numbers look impressive, the data actually showed a ratio of 90 to 92% maximum.
So that a large number of electrical appliances can be used at the same time, the temperature in the coolant of the heating system can be reduced, thereby saving electrical energy. Each case has its own ways of saving, in contrast to the use of other heating systems. for example, in order to heat a house with an area of 50 m 2 , an electric boiler is needed with a power of 3 kW.
If you have all the required data at hand, it will be easy to calculate how many kW per month you will consume during continuous operation of the device.
For example, the area of the house is 50 m 2 , and the boiler power is 3 kW. It turns out such a calculation - 3 * 24 * 30, where 24 is the number of hours in a day, 30 is the number of days in a month, and as a result we get 2160 kW per month with a continuously operating boiler, and then multiply this figure by the electricity tariff that is installed in your region. The calculation is approximate, since the actual volume spent will be noticeable only later. Only after that it will be possible to make adjustments to the heating system, select auxiliary devices that will be advisable to use for savings, and so on.
If you need to heat your home, but do not lay highways and install a huge number of devices, you can use a convector. Unlike water electric heating in a convector, the main principle of operation is to heat the air and release it into the environment. The system is almost autonomous, compact enough and can heat a room with a small area. Convectors have temperature controls, with which you can set the heating parameters that are optimal for yourself. In the presence of automation, you will be provided with full on / off of the device, depending on which temperature mode is selected.
To install this type of heater, you must have good outlets and good wiring.
The convector can be installed both on the wall and on the floor. The cooled air will go down, and then come under the influence of the heating element, once again heat up and rise, and so on in a circle. This is how the process of convection of air masses is achieved. The operating mode of heating the convector ranges from 60 to 100 degrees.
The additional room can be equipped with fans to help speed up the air exchange.Despite the fact that the design and principle of operation of the convector seem simple, heating with their help is uneven. The air under the ceiling will be warmer, and cold below will be felt.
If you use a convector instead of a boiler for heating a house with electricity, and you want to save money when using it, it is enough to carry out a simple calculation that will determine how many appliances are required for normal heating. As practice shows, convectors are really effective when used in residential and domestic buildings made of wood, but in a house with a large area it is impractical.
Large volumes of air will quickly cool down, the heating time will increase, which means that the consumption of electrical energy will increase.
A boiler and a convector are far from the only options in order to equip your house with a good system heating, which is powered by electricity. Underfloor heating, which has now become fashionable to use in apartments and country houses, can be a good alternative to any other heating options. If we talk about this from the point of view of physics, then a warm floor will not give a noticeable effect, but compared to the work of other heating electrical devices, it is due to the floor that you can reduce electricity consumption.
The effect is achieved due to the rational distribution of heat.
Floors, as we know, represent the coldest part of any room. Due to the warm floor, the coldest part of the house will become a source of thermal energy and will no longer play the role of a cooler. The floor, evenly heated from below, heats the air and it rises in streams upwards. For residential premises, underfloor heating helps to save up to 40%, for heating other premises, savings up to 50%, and sometimes even more.
Using the temperature regulator, you can set the optimum values for heating.
It is not difficult to determine the temperature regime on your own, and after that you can achieve great savings in electrical energy.
Advantages of underfloor heating:
Against the background of the advantages that the warm floor has, the only drawback is not so terrible. The problem lies in the difficulty of installing such a home heating system with electricity, since this is due to the need to reorganize the flooring. A preliminary calculation should be made. Approximate wattage for standard household models. Equal to 1.
5 kW / 10 m 2 . It calculates the average consumption and we get a figure of 360 kW / month. For the rest of the premises, we also carry out the calculation, the power will change in direct proportion to the area.
Today there are a huge number of options for how to achieve comfort inside your home using electric heating. Each of us can choose which heating option suits him best.
Underfloor heating, an electric boiler or other appliances are options that will help solve various problems. You can approach this issue globally and create a whole heating system, or solve the problem locally. In any case, there are all ways to save money if you equip the house with additional elements that will help reduce heat losses in the home and improve the operation of the entire system in the house.
