Electric boiler for home heating (50 square meters): overview, characteristics, features of choice and installation

Before choosing an electric boiler for heating the house, it is necessary to determine the capacity of the heating equipment, considering that 10 square meters will require one kilowatt. In this case, the building must be well insulated, and the height of the ceiling should not be more than 3 meters.

Choosing a boiler for economy

In order to be able to save electricity, it is best to purchase a device that will allow you to regulate power. Selection and installation of electric boilers for heating the house provides for the possibility of purchasing a model with automatic adjustment. In this case, the unit will consume the amount of energy that is needed to maintain a certain temperature level. This will reduce costs.

Features of choice

If you want to make a choice of an electric boiler for heating in a private house, you can choose a model equipped with a microprocessor control unit. With it, you can adjust the power more smoothly. At a price, such units are more expensive than and differ from the standard ones, but in the process of operation they pay off due to energy savings. Experts advise choosing the boiler equipment to pay attention to the equipment. Almost all devices are equipped with circulating pumps and an expansion tank, which allows the appliance to be used not only for heating the room, but also for the preparation of hot water. These two functions of the equipment will perform simultaneously.

If you want the device to last as long as possible, you should choose the models of the latest generations that have different levels of protection against aggressive influences. These include frost protection devices, a coolant cleaning filter, and the ability to work in winter and summer conditions.

How to calculate the power of the electric boiler for heating the house, has been described above. But this is not the only parameter that needs to be guided. It is important that the device has a thermoregulator, it saves energy by maintaining different temperatures in separate rooms. The consumer will only have to set a certain value, and the system will track it automatically.

Types of boilers for automation

If you need an electric boiler for heating, the types of such equipment should be considered in advance. Thus, in the market of the corresponding goods one can find devices that are equipped with different types of automation, namely mechanical or electronic. Mechanical automation includes the simplest control devices, such as bimetal thermostats, thermal relays, second, fourth and sixth contactors. The advantages of such units are low cost, but there are also disadvantages, they are expressed in strong cotton at work, as well as not very accurate heating control. Most often, units with mechanical automation are used in production, storage and non-residential premises.

When to choose a boiler with electronic automatics

For home owners who wish to save money, electronic automation, which provides precise control of heating, is best suited. The noise figure will be approximately 20% lower, and the thermostat will demonstrate the ability to maintain a certain temperature in the automatic mode, taking into account additional heat sources. It is advisable to install the thermostat in those rooms where there are additional heat sources, here you can include the kitchen.

To regulate the heat transfer of the device in order to save resources, there are automatic thermostats. The heat balance in the room can be restored by changing the amount of heat that comes from the heaters into the room. This is the main task of thermoregulators. In thermostats there are sensors that react to the slightest changes in air temperature. The device saves up to 20% of thermal energy. The most common are liquid thermostats, although they are more expensive. However, their service life is longer and is 20 years.

Overview of the characteristics of the electric boiler "Luch" (5 kW)

If you need an electric boiler for heating a house of 50 square meters, it is important to initially calculate the power using the recommendations presented above. According to them, equipment with a capacity of 5 kilowatts will be needed for this area. An excellent example will be the model "Ray" (5 kW), which will be able to heat the maximum area of 70 square meters. This will come in handy if you plan to increase the area of the house. With the operation of this device, the volume of coolant in the system can be equivalent to 100 liters.

The equipment includes a boiler in a protective casing, a coolant temperature sensor, a control unit, and an electronic temperature controller. To reduce the cost of heating the owners will be able to do it due to the correctly chosen program of boiler operation in time. The kit allows you to program the temperature in the room by periods, and also control the pump. Before purchasing such an aggregate, it is necessary to take into account its dimensions, since it is important to allocate free space for installation works. Thus, the width, height and depth are 110, 250, 100 millimeters, respectively.

The main characteristics of the boiler "Evan Warmos Comfort" (5 kW)

Choosing an electric boiler for heating a house of 50 square meters, you can consider as an option the above model, which you can buy for 13,700 rubles. It is a stationary electric heater that can be used in domestic, industrial and residential environments. Its operation is possible as a temporary, additional, main and reserve heat source provided that sufficient electric power is available.

The installation of such an assembly in the projected or existing water heating systems will not be accompanied by difficulties. Installation does not provide additional measures for the type of chimney device, window openings or foundation. However, this electric boiler for heating a private house at 50 square meters. M must be installed by qualified specialists in compliance with electrical safety requirements.

Installation Recommendations

Electric boilers offered for sale can be wall-mounted and floor-standing. The first option does not provide for the construction of an additional foundation, while the floor equipment will need to be mounted on a special stand. The unit must be connected to the mains and grounded. The electric boiler is connected to the heating system, from which it is necessary to remove air. After that, it's important to analyze its condition before launching. In carrying out such work, some tools may be needed, namely: a perforator, a mounting plate, flanges, pipes for creating a heating system, couplings, and a cable for connecting instruments. Drill or perforator should be prepared in the case when it is necessary to create holes for fasteners. With the help of anchors or a mounting plate, you will be able to attach the device.

If you purchased an electric boiler for heating a house (50 square meters), and its installation should be done on a wall, it is important to check the strength of the wall and whether it will withstand the weight of the equipment before starting the manipulations. The location for installation should be chosen taking into account that near the boiler there was enough space for preventive and repair work, which during the operation will have to be carried out more than once. It is important to locate the body of the device in such a way that it does not have any distortions and deviations in the level.

Nuances of works

If you have to install an electric boiler on the wall for heating the house (50 square meters), it is important that the surface is made of non-combustible materials. Apparatuses with low power can operate from 220 volts, whereas when selecting more powerful units, a connection to a three-phase network is required. An important point is the correct determination of the cable cross-section: this is necessary in order that it can withstand the power and has the ability to pass a current of a certain magnitude.

Before connecting the device to the mains, it is necessary to install in advance the machines and RCDs of the corresponding ratings. The master must perform grounding work. The cable is equipped with a switch that has a contact spacing of 3 millimeters.

Conclusion

If you need an electric boiler for heating a house of 100 square meters, then the capacity of the equipment should be increased by 5 kilowatts. An obligatory requirement in any case for open systems is the installation of shut-off valves, which should be located on the pipeline section after the expansion tank.
