A flexible heat pump is a modern version of a heat pump that uses new technology which enables them to operate more efficiently and effectively. Flexible heat pumps basically incorporate a small water tank and copper tube coil to create a heat storage vice.
The water tank takes the extra thermal energy from the pump’s operation and stores it as an extra heat source when the pump is back in use. Furthermore, the recovered heat is a lot warmer than the outdoor air which usually works as the main heat source, and can be re-used as a temporary source of heat, significantly decreasing the amount of energy the pump uses in operation.
As well as this, flexible heat pumps are also able to continue working even whilst defrosting in freezing conditions due to the included water tank holding onto recovered heat, which is far from the case with standard designs that continue to use electricity even when out of use in defrosting.
