PV powered vapour compression heat pumps-news-107

May. 18, 2006 – Sweden – One argument commonly raised by heat pump critics is that heat pumps use electricity, and that marginal production of electricity is based on the use of oil or coal.

A Swedish company, Ekosol, has developed a concept for powering heat pumps from photovoltaic (PV) solar panels, and thus, in theory, eliminating the need for an external power supply.
