Date Nov. 12, 1981.A heat recovery device comprising a heat pump (1) the vaporizer of which receives heat from the exhaust air (P1) of a building and the condenser (6) of which delivers heat to the water in a container (2) for hot consumption water. A circulation circuit (14,11,12,9) for the recovery of excess heat from the container (2) to the building is arranged in heat transferring contact with the water in a lower part (Z1) of the container (2), the condenser (6) and a supply connection (9) for cold water being likewise situated in the lower part of the container. This arrangement results in separation of the water temperature in the container (2) and increased efficiency of the heat pump (1). |
