This study identifies new developments since the publication of the results of the IEA HPC Analysis “The impact of heat pumps on the greenhouse effect” in 1992. It reviews 21 new studies and provides extensive emission data on heating and space conditioning equipment. One study deals with the energy impact of heat pumping technologies (heat pumps and refrigeration), six examine the effect of heat pumps on greenhouse gas emissions in general, fifteen examine the effect of alternative heating technologies and four compare heat pumps with district heating for cogeneration.
This in-depth study of emissions from heat pumps, gas- and oil-fired boilers, reversible air conditioners, and cooling equipment render this report an excellent data source for policy makers, environmentalists, and all those involved in heat pump promotion. The HPC believes that this report constitutes a valuable and timely contribution to the knowledge and insight into the benefits of heat pumps in reducing global warming due to energy use.
