Abstract

Heat pumps are a promising invention for household buildings that deliver extremely high performance compared with the combustion of fossil fuels. A billion thermal pumps have been used worldwide in the field, but they are a very recent technology in many regions considering their maturity. This article offers a description of emerging technology and practical challenges that occur as they are mounted and run. It focuses on actual results, by analyzing reported efficiency data for hundreds of air sources and heat sources of the ground. Pumps and a tool to link the findings of recent field studies in the UK and Germany (ASHP and GSHP) Pumps. It also includes trading facets of technology, typical primary energy savings, decreased carbon dioxide emissions and more widespread consequences of their use.
