Abstract

A heat recovery device recovers heat from a waste water pipe or the like. The device includes an evaporator chamber surrounding a length of the pipe. The chamber contains a refrigerant in both liquid and vapour states. A
wick surrounding the pipe within the evaporator chamber extends into the liquid state refrigerant. A vapour outlet from the evaporator chamber above the liquid refrigerant leads to a condenser chamber around a container for liquid to be heated. The condenser chamber has an outlet connected to the evaporator chamber for delivering liquid refrigerant from the condenser chamber to the evaporator chamber. Heat in the pipe evaporates refrigerant from the wick. The evaporated refrigerant then travels into the condenser chamber where the cold surface of the water chamber extracts heat from the refrigerant and condenses it to be discharged back to the evaporator chamber. The water container in the condenser chamber is connected into the hot water system.
