An apparatus for heating water has a tank for storing water and an air conditioning system that defines a refrigerant flow path through which refrigerant flows. The refrigerant flow path passes through a heat exchanger so that refrigerant heat is contributed to the tank. The heat exchanger houses a phase change material. A controller controls operation of the water heating apparatus.

A system for providing air conditioning to a living space and heating potable water. The system comprising a heat pump circuit comprising a compressor for circulating a refrigerant around the heat pump circuit, a first condenser, a second condenser and an evaporator. The evaporator being adapted to receive a first flow of air from an air inlet to transfer heat from the first flow of air to the refrigerant. The first condenser being adapted to receive a flow of water to transfer heat from the refrigerant to the water. The second condenser being adapted to receive a second flow of air to transfer heat from the refrigerant to the second flow of air. The first flow being provided from the evaporator to a living space by an air outlet.

This invention relates to a heater. A combustion air blower feeds combustion air to a burner device. The burner device burns a gas-air mixture from the combustion air and a fuel and serves for heating air. A circulating air blower discharges heated air from the heater. A control device acts on at least one component of the heater, wherein a night mode parameter set associated with an operation of the heater in a night mode and a default parameter set are stored in a data storage device. After an activation of the night mode, the control device accesses the night mode parameter set and uses the same for acting on the component. The night mode parameter set effects a reduction of background noise generated by the heater.
