BOOSTHEAT 20kW - Halve energy consumption for space heating, hot water and air-conditioning in households

boostHEAT designs, develops and assembles heat pump boilers based on an innovative thermal compression technology.

boostHEAT has developed the bH 20kW low carbon heat pump boiler to replace old coal and oil heating systems. It uses a thermal compressor, which uses heat from natural gas combustion to efficiently compress a natural coolant (CO2) instead of harmful HFC refrigerants. The unique design of the thermal compressor allows for operation of a high temperature thermal compression cycle, pumping heat with a world-record output of 200% Seasonal Gas Utilisation Efficiency (SGUE). The four-stage thermal compressor, optimized for size and with a hermetically sealed design allowing it to function at high pressure can reduce gas consumption by up to 50%.
