An apparatus (5) for heating water, the apparatus (4) including a non-pressurised tank (14) adapted to contain a heat exchange media, a heat pump (12) in fluid communication with the non-pressurised tank (14), a controller (104) in communication with the heat pump (12) and a temperature sensor (102) in communication with controller (104). The tank (14) includes a first conduit (16) in fluid communication with the heat pump (12) so as to carry a refrigerant, and a second conduit (18) arranged to be communicable with an external water source so as to carry water, the first conduit (16) and the second conduit (18) being arranged relative to one another within the tank (14) such that heat from the refrigerant carried by the first conduit (16) is transferable through the heat exchange media to the second conduit (18) so as to allow heating of the water carried by the second conduit (18). The temperature sensor (102) is arranged relative to the heat exchange media to provide temperature information to the controller (104) indicative of the temperature of the heat exchange media, the controller (104) being configurable to receive the temperature information to thereby allow selective operation of the heat pump (12) to maintain the heat exchange media above pre-determined minimum temperature. A water heating system and a method for heating water is also disclosed. |
