Abstract

A method of defrosting an evaporator of a heat-driven heat pump is described, where the evaporator is for extracting heat from an ambient heat source outside an entity to be heated when the heat pump is driven using heat from a driving heat source. At least some of the heat from the driving heat source is used to defrost an exterior surface of the evaporator.
