Modern energy-saving electric boilers for a house or apartment are an ideal budget-type heating option. To ensure a balance between temperature and energy consumption, it is necessary to calculate the device, taking into account the area of \ u200b \ u200bthe rooms in combination with the physical properties of the materials from which the walls, floor and ceiling of the room are made.
The required power of the boiler for heating the house
Before choosing and installing a standard energy-saving electric boiler, you need to calculate the operating power of the unit. Correctly selected equipment will be able to maintain the optimal temperature in the room, regardless of external conditions.
For 50 m²
An electric boiler for heating a 50 m² private house must have a total power of no more than 5 kW. The best option would be a model with a quality pump, complemented by an expansion tank with a control panel and display.
For 100 m²
When choosing a boiler for a house with an area of up to 100 m², devices with a capacity of 12 kW or more are considered. This installation must be supplemented with an automatic air vent, thermometer and modular contactor.
For 150 m²
An electric boiler for heating a house of 150 square meters must have a power of 15 kW. It can be single-circuit or double-circuit, wall-mounted or floor-standing. Boilers with such a power are classified as three-phase and are capable of operating at a voltage of 380 Volts.
For 200 m²
In rooms with an area of up to 200 m², it is necessary to install boilers with an output of 25 kW. It can be a modern induction model or a more budgetary standard model.
Types of electric boilers
Electric boilers are divided into several categories, the list of the most popular includes electrode, induction and heating elements. They differ in the set of options, characteristics and design.
Electrode
Heating boilers of the electrode type operate by electric current, the effect on the coolant in them occurs by increasing the resistance level. The list of their advantages includes small dimensions, affordable cost and the ability to install automation. Users note such disadvantages as the need for grounding and high-quality coolant, as well as the lack of protection. There are electrode boilers on the market with a power in the range of 2-10 kW and an efficiency level of 95%.
Heating elements
Devices with heating elements are supplemented with a tubular heating element and work due to the circulation of the heat carrier. They are equipped with a temperature control system with protection against pressure drops. They have a simple design and are quite versatile, but at the same time they are susceptible to corrosion and salt deposits.
Induction
Induction devices work using alternating electromagnetic fields, after connecting to the network, the effect in them is carried out on the coil. A core is located inside them, when electromagnetic fields appear in the device, an eddy current is formed, the metal begins to gradually heat up. The heat carrier cools it down, then heats up, thus the heating process is carried out.
When choosing an electric boiler for heating a private house of 150 m², they pay attention to the main characteristics and additional features. The device must be sold fully equipped, installed according to safety rules, and protected against overheating of water and power outages. It is worth evaluating the design of the device as a whole, taking into account its size and the area of the room that it must heat.
Advantages of electric boilers
An electric boiler has many more advantages than a gas boiler. This list includes:
- no need to constantly be at home during the operation of the unit and monitor its operation;
- no need to create additional specialized communications;
- automatic shutdown in case of problems with the power supply or exceeding the permissible temperature.
An electric boiler for heating a house of 60 square meters or more needs powerful generators. On average, the power of a standard boiler should be at least 8-12 kW, it depends entirely on the area of the heated area. To prevent problems with voltage drops in the network and economical energy consumption, it is advisable to equip such a boiler with a three-phase network if they are installed in houses located in remote areas.
Before installing the boiler, you need to take into account the state of the internal and external power grids, as well as the characteristics of the substation, which is located near the house.
Gas or electric heating
When choosing between gas and electric heating, you need to take into account the quality and type of installed equipment. Users prefer more economical models, but the cost of gas and electric boilers with all components is approximately at the same level. The difference lies in the level of security and service.
Gas appliances need to be monitored by specialists, in contrast to electrical appliances, which are considered more reliable and safer.
Popular boiler models
Some boiler models are considered more priority due to their good technical indicators and characteristics. When choosing them, the equipment, functionality and cost of the device are taken into account.
For heating houses with an area of up to 50 m², experts advise choosing Russian and Italian-made appliances. This includes the ZOTA Balance-4.5 and SOLEN Lite 4.5, which are compact and easy to operate.
To heat a house with an area of up to 100 m², it is better to choose high-power appliances from manufacturers from Germany or Russia. The most suitable option is the ZOTA Balance 6 unit with a high-quality power relay for energy saving and a temperature controller.
When choosing a boiler for a room with an area of more than 150 m², it is necessary to look for a suitable option among installations with a high power level and choose a device with high-quality automation. It can be KOSPEL EKCO A-12 or VAILLANT eloBLOCK VE 12, supplemented by a protection system and innovative automation.
When it comes to a large room up to 200 m², it is better to choose devices such as the PROTHERM TLO 20. This model is supplemented with a piezo ignition and has an optimal power level.
