Modern energy-saving electric boilers for a house or apartment - an ideal option for heating a budget type. To ensure a balance of temperature and energy consumption, it is necessary to calculate the device, taking into account the area of the rooms in combination with the physical properties of the materials from which the walls, floor and ceiling of the room are made.
Necessary boiler power for heating a house
Before you select and install a standard energy-saving electric boiler, you need to calculate the working power of the unit. Properly selected equipment will be able to maintain optimal indoor temperature, regardless of external conditions.
For 50 m²
An electric boiler for heating a private house of 50 m² should have a total power of not more than 5 kW. The best option would be a model with a high-quality pump, complemented by an expansion tank with a control panel and a 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. Such an installation should be supplemented with an automatic type air vent, a thermometer and a modular contactor.
For 150 m²
An electric boiler for heating a house of 150 square meters should have a power of 15 kW. It can be single-circuit or double-circuit, wall or floor. Boilers with this power are classified as three-phase and are capable of operating at voltages of 380 volts.
For 200 m²
In rooms with an area of up to 200 m², it is necessary to install boilers with a capacity of 25 kW or more. It can be a modern induction or more budget standard model.
Types of electric boilers
Electric boilers are divided into several categories, the list of the most popular includes electrode, induction and TEN models. They differ in a set of options, characteristics and design.
Electrode
Electrode-type heating boilers operate due to 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 a high-quality coolant, as well as the lack of protection. There are electrode boilers on the market with a capacity in the range of 2-10 kW and a level of efficiency of 95%.
Heating elements
Devices with a heating element are supplemented by a tubular heating element and operate due to the circulation of the heat carrier. They have a temperature control system with protection against pressure drops. They have a simple design and are quite versatile, but at the same time susceptible to corrosion and salt deposition.
Induction
Induction devices operate using alternating electromagnetic fields, after connecting to the network, the impact in them is carried out on the coil. A core is located inside them, when electromagnetic fields occur, an eddy current is generated in the device, the metal begins to gradually heat up. The heat carrier cools it, then heats up, thus the heating process is carried out.
Choosing an electric boiler for heating a private house of 150 m², pay attention to the main characteristics and additional features. The device must be sold fully loaded, installed in accordance with safety rules, have protection against overheating of water and power outages.It is worth evaluating the design of the device as a whole, given its size and the area of the room that it should be heated.
The advantages of electric boilers
An electric boiler has much more advantages than a gas boiler. This list includes:
- the lack of the need to constantly be at home during the operation of the unit and monitor its operation;
- lack of need to create additional specialized communications;
- automatic shutdown in case of problems with the power supply network 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 completely depends on the area of the heated area. To prevent problems with power surges 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 condition of internal and external power networks, as well as the characteristics of the substation, which is located near the house.
Gas or electric heating
When choosing between gas heating and electric, you need to consider the quality and type of equipment installed. 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 safety and service.
Gas appliances need to be monitored by specialists, unlike electrical units, which are considered more reliable and safe.
Popular boiler models
Some boiler models are considered higher priority due to good technical indicators and characteristics. When choosing them take into account the configuration, functionality and cost of the device.
For heating homes up to 50 m², experts advise choosing appliances of Russian and Italian production. This includes ZOTA Balance-4.5 and SOLEN Lite 4.5, which are compact in size and easy to operate.
To heat a house with an area of up to 100 m², it is better to choose devices of increased power 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 plants 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, complemented by a protection system and innovative automation.
If we are talking about a large room with an area of up to 200 m², it is better to choose devices such as PROTHERM TLO 20. This model is complemented by piezo ignition and has an optimal power level.
