There is a large need for reliable statistics for heat pumps. These data are necessary for publications such as those published by the IEA, and also in order to estimate the amount of energy savings and GHG emissions abatement. They should include number of heat pumps installed per year, but also details such as heat pump sizes, Seasonal Performance Factors (SPF), runtimes, lifetimes, and costs, for each heat pump type and country.
We here discuss available heat pump data. We show that heat pump statistics collection needs to be improved. Suggestions for a future statistics collection and evaluation
methodology is presented, taking into account data collection, classification, and quality. Since the Heat Pump Programme is unique in that it has a global coverage, it is well suited to
play a decisive role in this process. The goal is to show the potential of heat pumping technologies for the future energy system.
