Summary

On behalf of the Swiss Federal Office of Energy, the FAWA (Field Analysis of Heat Pump Installations) Project systematically surveyed small heat pumps installed in Switzerland for a period of over five years. The data presently available represent measurements taken on a total of 120 installations. Statistical analysis has led to interesting conclusions on the energy conversion efficiencies of the heat pumps surveyed and successful installation designs: during the period 1994/1995 to 1998, the mean energetic efficiency of heat pumps in Switzerland, taken as a whole, as expressed by the seasonal performance factor, improved from 2.6 to 3.2; systematic measurements taken on individual installations over five years have shown that the value of the seasonal performance factor remained constant over this time frame - in other words ageing was not a significant factor.
