The aim of this project was to demonstrate and disseminate the economic, environmental and energy saving potential of heat pumping technology. The focus has been on available technology, and results from existing field measurements have been used to calculate energy savings and CO2 reduction.
The heat pump systems included in this project are the best we have found in our field measurements. The SPF values for the studied heat pump systems range from 2.6 to 4.7. Four ground-source heat pumps and five air-source heat pumps ended up at SPF values above the limits we defined for systems to be regarded as good (2.8-3.2 for air-source heat pumps and 3.3-3.9 for ground-source heat pumps).
