At the 13th IEA Heat Pump Conference it is expected as in Rotterdam that there will a great number of presentations on Heat Pump Water Heaters.  Under the Task 3 for the Annex we have been active to make an overview of Modelling of Heat Pump Water Heaters with a focus on storage size, heat exchangers, stratification and refrigerants. Many models are used worldwide, also related to Solar Thermal and Photovoltaics.

It is envisaged, dependent on available manpower that at the Heat Pump Conference there will a half-day workshop to bring together experts and discuss how to exchange idezs on the road ahead.
