A new Annex 38 in the Heat Pump Programme of the International Energy Agency started in 2010 and will last until end of 2013. “Solar and heat pump systems” Annex aims at understanding the best combinations of a heat pump and solar collectors for a one family house. The heat pump can be of any type. Several countries participate in this Annex and bring their experience and projects together to get the most of the international collaborative work.
