Domestic heat pumps: Life cycle environmental impacts and potential implications for the UK

Greening, Benjamin; Azapagic, Adisa - In: Energy 39 (2012) 1, pp. 205-217

This paper presents the results of a life cycle assessment of domestic heat pumps in the UK in comparison with gas boilers. The study considers air (ASHP), ground (GSHP) and water (WSHP) source heat pumps. The results show that heat pumps have higher environmental impacts than gas boilers due to...
