Résumé

This article analyses the opportunities of heat pump applications in the refurbishment of existing buildings. The first issue is the temperatures in the heating system. The high original design temperature for the radiator system, mostly incompatible with the heat pump operations, is mainly due to poorly insulated buildings. The improvement of the building envelope insulation during the refurbishment makes it possible to reduce the radiators supply water temperature and improve the COP of heat pump. The second problem is the production of domestic hot water.
