Before choosing an electric boiler for heating a house, it is necessary to determine the power of the heating equipment, given that one kilowatt will be needed per 10 square meters. At the same time, the building should be well insulated, and the ceiling height should not be more than 3 meters.
Choosing a boiler to save
In order to be able to save energy, it is best to purchase a device that will allow you to adjust the power. The selection and installation of electric boilers for heating a house provides for the possibility of acquiring a model with automatic adjustment. In this case, the unit will consume as much energy as is necessary to maintain a certain temperature level. This will reduce costs.
Features of choice
If you want to make the choice of an electric boiler for heating in a private house, then 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 they differ from standard ones, but during operation they pay off due to energy savings. Experts advise when choosing boiler equipment to pay attention to the equipment. Almost all devices are equipped with circulation pumps and an expansion tank, which allows you to use the device not only for heating the room, but also for preparing hot water. The equipment will perform these two functions at the same time.
If you want the device to last as long as possible, you should choose the latest generation models that have different levels of protection against aggressive influences. This includes protective devices against freezing, a filter for cleaning the coolant, as well as the ability to work in winter and summer modes.
How to calculate the power of an electric boiler for heating a 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 thermostat, it allows you to save energy by maintaining different temperatures in individual rooms. The consumer will only have to set a specific value, and the system will track it automatically.
Varieties of boilers for automation
If you need an electric boiler for heating, it is recommended to consider the types of such equipment in advance. Thus, in the market for relevant products, one can find devices that are equipped with different types of automation, namely mechanical or electronic. Mechanical automation provides for the simplest control devices, such as: bimetallic thermostats, thermal relays, contactors of the second, fourth and sixth magnitude. The advantages of such units are low cost, but there are also disadvantages, they are expressed in strong bangs during operation, as well as not too precise control of heating. Most often, units with mechanical automation are used in industrial, warehouse and non-residential premises.
When to choose a boiler with electronic automation
For homeowners who want to save money, electronic automation is the best choice for precise heat control. The noise figure will be about 20% lower, and the thermostat will demonstrate the ability to maintain a certain temperature in automatic mode, taking into account additional heat sources. It is advisable to install a thermostat in those rooms where there are additional sources of heat, this may include the kitchen.
To adjust 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 thermal appliances into the room. This is the main task of temperature regulators. Thermostats have sensors that respond to the smallest changes in air temperature. The device saves up to 20% of thermal energy. The most common today 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 brand "Ray" (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 the indicated area. An excellent example is the Luch model (5 kW), which will be able to heat a maximum area of 70 square meters. This will come in handy if you plan to increase the area of the house. When using this device, the volume of coolant in the system can be equivalent to 100 liters.
The complete set of the device includes a boiler in a protective casing, a coolant temperature sensor, a control unit, as well as an electronic temperature regulator. The owners will be able to reduce heating costs thanks to a correctly selected boiler operation program in time. The package allows you to program the room temperature by periods, as well as control the pump. Before purchasing such an aggregate, it is necessary to take into account its dimensions, because it is important to allocate free space for installation work. Thus, the width, height and depth are 110, 250, 100 millimeters, respectively.
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 aforementioned model, which can be purchased for 13,700 rubles. It is a stationary electric heating device that can be used in domestic, industrial and residential premises. Its operation is possible as a temporary, additional, main and backup heat source, provided sufficient allocated electric power.
Installation of such a unit in designed 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 of 50 square meters. m must be installed by qualified specialists in compliance with electrical safety requirements.
Installation Recommendations
Electric boilers for sale can be wall and floor. The first option does not provide for the arrangement of an additional foundation, while outdoor equipment will need to be mounted on a special stand. The unit must be connected to the mains and ground. The electric boiler is connected to the heating system, from which air must be removed. After it is important to analyze its condition before starting. When carrying out such work, some tools may be needed, namely: a perforator, mounting plate, flanges, pipes for creating a heating system, couplings, and also a cable for connecting devices. A drill or perforator should be prepared when it is necessary to create holes for fasteners. Using anchors or a mounting strip, you can attach the device.
If you purchased an electric boiler for heating your home (50 square meters), and it must be installed on the wall, it is important to check how strong the wall is and whether it will support the weight of the equipment before starting the manipulation. The installation location should be chosen taking into account that there is enough space near the boiler for carrying out preventive and repair work, which will have to be carried out more than once during operation. It is important to position the case of the device so that it does not have distortions and deviations in level.
The nuances of the work
If you have to install an electric boiler on your wall for heating your home (50 square meters), it is important that the surface is made of non-combustible materials. Devices with low power can operate from a 220 volt network, while when choosing more powerful units, connection to a three-phase network will be required. An important point is the correct determination of the cable section: this is necessary so that it can withstand power and has the ability to pass a current of a certain value.
Before connecting the device to the mains, it is necessary to install automatic machines and RCDs of the corresponding ratings in advance. The master must carry out grounding work. The cable is equipped with a switch, which has a distance between the contacts of 3 millimeters.
Conclusion
If you need an electric boiler for heating a house of 100 square meters, then the power of the equipment should be increased by 5 kilowatts. An obligatory requirement in any case for open-type systems is the installation of stop valves, which should be located on the segment of the pipeline after the expansion tank.
