When choosing suitable equipment for heating a house or cottage, you should pay attention to inverter-type equipment. The operating principle of such devices is based on the conversion of alternating current to bring them to the required parameters.
Among the differences of an inverter heater are efficiency, low noise level and a small range of temperature fluctuations in the room.
The characteristics of the equipment are superior to infrared and water heating. And before buying, you should get acquainted with the selection criteria and the most popular models.
Criteria for choosing an inverter heater
A gas appliance is more profitable, but more dangerous to operate
The first thing people pay attention to when choosing inverter heaters is power. Productivity is calculated using different formulas. The first is the same as for a conventional heating radiator.
It is assumed that for heating 1 sq. m, 100 W of power is enough. For a 10-meter room you need a 1 kW device, for 20 sq. m – 2 kW. The second method of calculation is by volume.
First, the number of cubic meters is determined, then it is multiplied by the appropriate coefficient. For reinforced concrete panel houses it is 41 W/cubic meter. m. for the rest - 34 W per cubic meter. m.
When choosing an inverter type air conditioner, the main criteria are:
- Manufacturer. The Toshiba and Mitsubishi brands belong to the premium class. Timberk – to medium. Ballu and Electrolux - to the budget segment.
- Energy carrier – electricity or gas. Electric models are most often chosen. A gas appliance is more profitable, but more dangerous to operate.
- Energy consumption. Mitsubishi brand models are characterized by high energy consumption. Toshiba products are considered the most energy efficient.
- Availability of a serial number on the device. This is also a sign of quality technology.
Buyers of equipment should check the availability of certificates and marks of conformity. Products that meet international standards and are safe for health must have such documents and symbols. You can find certificates on the websites of consumer electronics stores.
Comparison of an inverter system with heating using an electric boiler
What conclusion can be drawn after six months of operation:
- The heating system based on Electrolux inverter convectors is a complete home heating system. It can automatically regulate the temperature and is convenient to control, including remotely.
- The inverter system is much cheaper in terms of equipment and installation costs.
- The inverter system is much more economical. According to research by the Moscow Energy Institute, such savings reach 40%. This is explained by the high inertia of the heating system according to the “boiler-radiator” scheme while maintaining a given temperature.
- System reliability. If one element of the inverter system breaks down, the house will not freeze, which cannot be said about the heating system on the boiler. If the boiler or pump fails, the entire heating system of the house will stop working. And it is not always possible to quickly solve a problem without the help of a specialist.
- Aesthetics: no white polypropylene pipes on the walls, space saving - no boiler room needed.

Why is it economical
Inverter heaters are considered one of the most cost-effective devices. How does this manifest itself? Let's start with the fact that such systems, having reached the required temperature level, do not completely turn off. The device continues to operate, reducing the speed to a minimum. This process leads to maintaining a comfortable and favorable climate in the room. At the same time, the heater does not waste extra electricity turning it on and off.
In addition, inverter heaters do not use “high current” for starting during their use. This is also beneficial for consumers. When starting the unit, the current does not exceed the rated current. And this has a positive effect on the service life of such devices. In this case, the device is not constantly in the on and off mode. Such cycles significantly reduce the life of the equipment. It is worth noting that, unlike conventional heating devices, inverter heaters can save up to 40% of electricity.

What is
Inverter heaters are able to control the heating process automatically. So, for example, when the set air temperature is reached, the system does not turn off, as in other devices, but switches to a reduced power level. Due to this operating principle, it is possible to maintain the desired level of heat in the room. The heater consumes much less energy, since there is no need to constantly turn the device on and off.
The operating principle of an inverter heater is similar to that of an air conditioner. The main working part in it is a heat pump, the basis of which is the internal and external units. The first contains a heat exchanger, inside of which freon accumulates under high pressure. Freon temperature can reach 80 degrees. After this, it enters the external unit, where lower pressure is observed. Here freon is transformed from liquid to gaseous state. As a result of its transition, a large amount of thermal energy is released.
An inverter heater is very efficient. Even if the room is very cold, the device begins to intensively heat it without reducing its efficiency.
Main characteristics
The operating life of inverter heaters is longer due to the absence of peak loads.
The installation converts the incoming alternating current into direct current, and then again converts the direct current into alternating current, but with different characteristics. As a result, the device does not work with mains electricity, but with current with improved performance. This prevents damage to the device during power surges: the heater lasts longer and operates with greater efficiency.
The work scheme is also changing. A conventional heater, when turned on, heats the air to a specified temperature, and when reached, turns off completely. When the sensor signals a decrease in the temperature in the room, the device turns on again. However, starting the device causes a short-term peak load. This mode contributes to rapid wear of parts.
An inverter heater for a home works differently. When turned on, the heater heats the air to the specified temperature, but after reaching it it does not turn off, but reduces the operating power to 5–10%. When the temperature drops below the marked value, the heater increases power.
In this mode, the power gradually increases and decreases, and there are no peak loads. The temperature also changes more smoothly, which allows you to increase shutdown time and reduce electricity consumption.
How does an inverter heating boiler work?
As a rule, if we consider classic electric boilers, then the principle of operation is that energy is transferred to the coolant using a heating element. So, if the design has a heating element, then it is also necessary to provide a separate place to heat the water, protect the heating element from the corrosion process, and also take into account heat loss.
Inverter (or induction) heating boilers operate on the principle of electromagnetic induction.
Thus, with the help of an alternating magnetic field, an induction current is generated. In order for this process to be implemented, direct current from the electrical network must be converted into alternating current. This is what the inverter does - it can work both from the network and from batteries.
So, an inverter heating boiler has two circuits:
- Magnetic. Generates an alternating magnetic field.
- Heat exchanger. Heats up the coolant.
When alternating current is applied, the coil creates a magnetic field, which heats the water in the pipe system.
Use in heating systems
Today, this device is used in heating systems where the power source is electrical energy, less often gas supply. It can be implemented wherever there is electricity. To use inverter heating, you do not need permits, and installation does not require approval from the relevant services. This device is much cheaper than others. A gas boiler can be easily replaced with an inverter heater.
