Air source heat pumps work by transferring heat from one place to another, rather than using fuel to generate heat directly. This makes them as efficient as 300% to 400%, that is, they produce 3 to 4 times more energy than they consume. Radiant heaters, such as furnaces or electric heaters, can reach a maximum efficiency of 80% to 90%.

Main factors affecting the efficiency of air source heat pumps
1. Evaporator
Represents air, floor heating or hot water heating. Daikin and Mitsubishi Electric are well known for their high-efficiency evaporators that can effectively dissipate heat at lower temperatures.
2. Compressor
The process of compressing refrigerant to increase its temperature. Since Copeland (Emerson) compressors are market leaders in energy-saving designs, significant cost savings are achieved.
3. Heat exchanger (condenser)
Transfers the absorbed heat to your living space heating system. Viessmann heat exchangers are highly efficient and have low heat losses.
4. Expansion valve
By measuring the refrigerant pressure, the internal pressure of the cooling system is reduced to prepare for the next cycle. Many manufacturers, such as Sporlan and Danfoss, provide high-quality expansion valves, which play a vital role in ensuring the stable operation of air source heat pumps.
