Annex 37 aims to expand acceptance of heat pumping technology and to increase take-up in new markets. The intention is to demonstrate energy and environmental potentials of heat
pumping technology, using existing field performance measurements, and with the emphasis on best available technology. It should be possible to predict the most suitable heat source
and heat pump system for particular applications. In order to ensure reliable results, it is most important that the quality of the measurements should be assured, and so the criteria for good and assured quality will be defined in the Annex. As the results will also be used to compare given heat pump systems with alternative heating systems, it is therefore important to define measuring conditions such as measuring points and system boundaries that influence energy savings and CO2 reduction. An important outcome of Annex 37 will be a data base of existing field measurements, using a common method to express performance values such as seasonal efficiency and energy
savings. The data base will be linked to the IEA Heat Pump Centre’s website.
