Gas-driven sorption heat pumps; a potential trend-setting heating technology

Increased efforts to reduce CO2 emissions and continuous increases in fossil energy prices have led to stronger
legislation concerning energy utilisation efficiency in the domestic heating sector. Accordingly, German
gas utilities and the key European manufacturers of gas heating appliances have teamed up to form what is
known as the “Gas Heat Pump Initiative” to introduce new heating technologies, which are capable of achieving
an incremental improvement of gas utilisation efficiency compared to that delivered by gas condensing
technology. This article provides a brief introduction to these innovative heating appliances and a presentation
of the gas heat pump initiative.
