To the free heat pump checklist https://schlau-energiesparen.de/wpc The best air-water heat pump in the world from Ovum achieves a SCOP of 6.02, which means that it produces an annual average of 6.02 kilowatt hours of heat for every kilowatt hour of electricity required for operation. With a heat pump tariff of 20 cents per kilowatt hour, this results in a heat production price of around 3.3 cents per kilowatt hour. The heat pump achieves its efficiency through optimal heat transfer in the finned register, with the air flowing through copper pipes and heat being transferred to the coolant. The phase change from liquid to gaseous in the coolant such as propane extracts energy from the environment, even at sub-zero temperatures. The compressor is the main component of energy consumption, with pressure determining the boiling point and thus the heating output. A carefully coordinated fan and fin package reduces the temperature difference and increases efficiency. The SCOP value is an important indicator that evaluates the efficiency of the device at different outside temperatures and is particularly suitable for unrenovated old buildings. A checklist for avoiding planning errors when buying a heat pump is helpful and is available on our website.
