Retrofitting with heat pumps in buildings.

Author(s) : BREEMBROEK G.

Summary

The potential market for heat pumps for retrofitting is about 3 times larger than the market for applications in new buildings. However, in most countries the actual market for retrofitting heat pumps is smaller than the market for heat pumps in new buildings. Market barriers include the high temperature distribution systems, the higher challenges on the economy of the systems and other circumstances, such as lack of space. The article discusses the market, the background of the market barriers and ways to solve them. Swiss experience has shown that current retrofitting of heat pumps works well, but have a 10% lower efficiency than applications in new buildings, which is quite favourable considering the 5 °C higher average distribution temperature. The operation experience supports the conclusion that all market players can benefit by targeted action to promote heat pumps in retrofit situations. Most results reported have been gathered as part of the project "Retrofitting with heat pumps in buildings" of the IEA Heat Pump Centre.
