Installing a heating boiler is an important stage in home improvement.If the equipment is selected correctly, then regardless of weather conditions, a comfortable temperature regime will be maintained in the rooms.
Electric heating boilers are often installed in private homes. The devices are safe, easy to use, and their performance depends on the choice of model.
In this material, we will understand the operating features of these devices, outline the criteria for choosing heating equipment, and announce the TOP 12 best manufacturers according to users.

Features of the electric boiler
The main design elements of an electric heating boiler are a tank and a heating element. The devices are equipped with monitoring and automatic control systems.
Also, various models may include expansion tanks and circulation pumps.
Electric boilers have several advantages:
- Fire safety. Thanks to automatic control systems and the absence of open flames, the devices are safe. They do not emit toxic substances or combustion products and are not capable of exploding.
- Ease of installation. Electrical equipment requires no flue or ventilation, making installation easy.
- High efficiency. Regardless of the type of heating device, all electric boilers are highly efficient.
- Compactness. Electrical appliances, especially wall-mounted ones, take up little space.
- Nice design. Most modern models are stylistically versatile and look good in the interior.
Electric boilers are almost ideal - easy to use and safe. Their only serious drawback is the high cost of electricity. One more nuance: for residents of regions where there are frequent interruptions in the power grid, it is better to choose boilers that operate from other energy sources, or take care of purchasing additional heating devices.
Criteria for classification of heating devices
The variety of electric boilers has a huge advantage: you can find a model that is ideal for specific operating conditions. At the same time, in order not to make a mistake, the buyer has to understand the nuances.
Electric heating equipment is classified according to several criteria, the main of which are:
- type of coolant heating: heating elements, electrode, induction;
- method of arrangement: mounted (wall-mounted), floor-mounted;
- design: one-, double-circuit.
Electric heating boilers may differ in other parameters. For example, some manufacturers produce not only single-phase models (220 V), but also three-phase (380 V).
There are also combi boilers, in which, in addition to electricity, other energy sources (wood or gas) can be used.
Heating element and electrode boilers are time-tested, reliable and will suit those home owners who are trying to find a model of decent quality at an affordable price.
Induction appliances are more suitable for people who value highly efficient technology and cutting-edge design. Their advantage is freedom of choice coolant: boilers can be connected to heating systems with non-freezing liquid.
When choosing between wall-mounted and floor-standing boilers, you should decide on the space in which you can place the device.
If you need a powerful boiler and the room is spacious, you should give preference to a floor-standing model, and for houses up to 100 sq.m. you can choose wall-mounted.
Any type of hot water electric boiler has advantages and limitations in use, so devices should be selected based on your own needs, priorities and operating characteristics of heating equipment.
The nuances of choosing the right model
Electricity is an expensive energy resource. If the boiler is selected incorrectly, you will have to pay huge electricity bills.
Therefore, it makes sense to pay attention to some nuances:
- Functions device. It is necessary to decide what functions the boiler should perform - only heat the house or additionally supply it with hot water.
- Technical indicators boiler Be sure to take into account not only the heated area, but also the degree of its thermal insulation.
- Price. In many ways, the cost of heating devices depends on power, but that’s not all. Additional features can lead to a significant increase in the price of the model. Therefore, you need to clearly understand whether your budget allows you to overpay for convenience.
Even before you start looking for a boiler, you should find out how powerful it should be.
You can calculate the power based on average indicators: 1 kW of electricity is enough to heat a room of 10 square meters. with ceiling heights up to 3 m.It turns out that to heat a small house with an area of 60 m2, a device with a power of 6 kW or more is suitable.
It is advisable to take into account the degree of thermal insulation and buy a boiler with a small power reserve (20%). If the house is poorly insulated, it is better to choose gas or solid fuel model, since heating with electricity will be too expensive.
What will help you save on heating?
There are several devices that help reduce energy consumption and reduce the cost of heating a home:
- Thermostats. Heating boilers equipped with thermostats do not overheat the rooms, but at the same time maintain the set temperature.
- Programmers. “Smart” boilers regulate the room temperature according to a specific schedule. Although the boiler itself is constantly running, the heating element consumes electricity only 34% of the time. Read more about installing a heating system in a smart home Here.
- Multi-stage power regulators. Thanks to automatic regulators, energy resources can be used extremely rationally.
- Microprocessors. The devices smoothly regulate the power of boilers, and some devices can even be controlled remotely - from smartphones or other gadgets. Such models are expensive, but worth the money spent.
The energy consumption of an electric boiler is significantly affected by the presence or absence of a circulation pump.
If it is not included in the model, it is advisable to purchase it separately and connect it to the heating system.
When purchasing a boiler for a country house or cottage, you should pay attention to antifreeze protection systems for the coolant.

I have my own house, I use a NAVIEN EQB single-circuit electric boiler. I connect an indirect boiler to it and heat the water. I set the water temperature on the boiler remote control, as well as other settings. It hangs on the wall in the kitchen, doesn’t get in the way, and makes no noise. Works like a clock. I have been using the boiler for the second year now, no complaints. There is a warranty from the manufacturer.
Heating with an electric boiler is expensive, but it saves money when there is no way to supply gas to the house. That's how it is with us. It’s a long way from the nearest highway; no one is planning to supply gas to the village yet. We bought a wall-mounted boiler and it hangs in the kitchen. A floor-standing one, of course, would be better, it is more reliable, but there is not enough space, and it is not possible to allocate space for it. One of the advantages I would like to highlight is that it is absolutely silent, you can adjust the temperature in the room, in terms of cost it is not the most profitable option, but it is of very high quality.On the downside, it really does consume a lot of electricity!
As for energy costs, here I can tell you a few tricks. They are not technical, but will still allow you to save money. Not many people know that you can get a discount if you design a home heating project exclusively using electricity, plus install a two-zone day/night meter. In this case, from 23:00 to 08:00 you will pay a reduced rate.
The next trick is technical: I advise you to get a thermostat, a thermostat; an advanced model costs about $10, which will make it possible to program the operation of the boiler even remotely by phone.
What does this give: for example, you are leaving somewhere on business or on vacation for a couple of days, so you can set the boiler operation to a minimum temperature of 16-18 degrees when no one is at home. You can also regulate the operation of the boiler on weekdays when everyone is at work. In combination with new tariffs, a meter and a thermostat, you can save up to 40% on your current energy costs.
