For every 1kw of electricity fed into the air source heat pump you could get at least 3kw of heating energy. The heat pumps will provide 55 degrees centigrade of water temperature's If the UK has any hope of meeting its ambitious net-zero targets by 2050, we must make the switch to sustainable heating systems, such as air source heat pumps. Heat pump technology has been used around the world for decades and Mitsubishi Electric have developed this technology to produce Ecodan - one of the most advanced, efficient renewable heating systems available today.
