In 100m depth where the temperature of the earth is constantly around 12°C. you put pipes filled with a special cooling agent and bring it up to the heat pump. Heating The heat pump compresses this liquid pushes its temperature up-to 55°C or even up-to 70°C. for your heating system. Cooling In summer you the heat pump only "heats up" the liquid up-to around 20°C and circulates through the heating system and absorbs the heat from the rooms and brings it down to the earth again. The effect is that your house will always have a delta of 10°C. to the outside temperature. | | |
