Heat pumps are electrical devices that consume electrical energy, while generating heat and cold for your home. The consumption of electrical energy is 4-5 times less than the consumption of an electric boiler. We get the same savings compared to gas heating. The direct process of heat generation occurs due to the evaporation and compression of freon (a special gas mixture) by a compressor. Actually, the compressor is a consumer of electrical energy. During this process, the temperature of freon rises and heats the coolant through the heat exchanger-condenser. The latter is fed into a conventional water heating system. At the same time, the freon itself cools and turns into a liquid. In order to repeat this process, it is necessary to evaporate (turn into gas) the cooled and condensed freon for further re-compression. But in order for freon to begin to evaporate, it needs to receive a new portion of heat. Due to the low boiling point of freon (even up to -40 C⁰), this heat can be, for example, soil with a temperature of 0 degrees. Even outdoor air with a temperature of -25 degrees is “warm” in relation to the colder freon. It is this effect that allows air/water heat pumps to work even in cold winter conditions.
