WebIt is normal for your heat pump to cycle on and off depending on the temperature of the home. A good rule of thumb is that it should cycle for about 10-15 minutes before turning off again. When the unit turns on and off too often, it could be indicative of a problem. Why does my heater keep running after it has reached the set temperature? WebThe cooled solution returns to the underground pipes to reheat in a continual cycle, providing heating and hot water for the lifetime of the heat pump. As underground temperatures are pretty constant (between 10-13°C) ground source heat pumps are more consistently efficient than air source heat pumps.
An ideal refrigerator or heat pump can be thought of as an ideal heat engine that is operating in a reverse Carnot cycle. Heat pump cycles and refrigeration cycles can be classified as vapor compression, vapor absorption, gas cycle, or Stirling cycle types.
