What is a heat pump? A heat pump is a machine that by reversing its refrigeration cycle can provide heating instead of cooling. Because a heat pump uses a refrigerant it can upgrade the heat in air at even -15ºC to a usable heat source to heat buildings. Difficult to understand perhaps but imagine a domestic fridge or freezer‚ reverse its cycle and that black grille on the back will be very cold whilst inside will be very hot. Heat pumps can extract heat from air and water and are nearly always
