The heat pump comprises of an outdoor unit, which can be placed 50 meters from the property, plus a hydrobox and a water tank. The heat is spread in the house using underfloor heating and also provide hot water. An efficient feature of this type of heat pump is the removal of stale air from the airtight, insulated homes through a mechanical heat recovery ventilation, which extracts the waste heat and uses this energy to warm up the fresh air from outside.
