According to Kesko’s website, the efficiency of an air source heat pump is excellent in early spring, making it a great time for heating. The manager responsible for procurement and business operations of wholesale Onninen’s renewable energy products, Arto Koivisto, explains that the efficiency of an air source heat pump improves as the frost decreases. This is because it takes energy from the outside air and releases it to heat the indoor air of a house.
The efficiency of an air heat pump is measured by its SCOP value, which refers to how much electrical energy it can convert into thermal energy. Koivisto emphasizes that the efficiency of the pump affects its benefit ratio, but it’s important to choose a pump that is suitable for your specific home. In a typical Finnish house and weather conditions, an air source heat pump can provide 40-60 percent of a home’s heating energy needs from outside air. By factoring in household electricity and domestic water heating, it is estimated that a house heated by direct electricity could reduce its electricity bill by up to one third with an air source heat pump. In addition to providing heating in early spring and summer cooling, this versatile device can also be used for year-round comfort in many homes.
