摘要： A heating system (100), a controller (110) for a heating system and a method of controlling a heating system (100) suitable for responding to grid stress events are disclosed. A heating system (100) comprises a tank (104) for holding water; a heat pump (102) arranged to provide heat to the tank (104); an electric heating element (108) disposed in the tank for heating water; and, a controller (110) configured to: control electric power from an electric power grid to the heat pump (102) and the electric heating element (108); detect a grid stress event; determine a heat pump energy penalty for providing heat in response to the grid stress event under a present operating condition; and, vary, in dependence on the determined heat pump energy penalty, a power provided to the electric heating element (108).

摘要： The present invention provides a water heating system (10) comprising: a tank (12) for holding a quantity of water and having a cold-water inlet (14) and a hot water outlet (16) and having a first upper zone (Z1) and a second lower zone (Z2); a heat exchanger (18) having a first side (20) for receiving heat (H) from a heat source (A) and a second side (22) for transmitting heat (H) to water to be stored within the tank (12); wherein said heat exchanger (18) includes an inlet (18a) into said second side (22) of said heat exchanger (18) and an outlet therefrom (18b); and wherein said system (10) further includes a water draw pipe (90) having an inlet (92) within said second zone (Z2) and an outlet (94) connected to said inlet (18a) to the second side (22) of the heat exchanger (18) for supplying water from zone Z2 to the heat exchanger (18) for heating therein; and wherein said heat exchanger (18) is external to the tank (12) and wherein said system (10) further includes a flow director (11) for directing flow of water from said outlet (18b) of second side (22) of said heat exchanger (18) to said second lower zone Z2.

摘要： Systems, kits of parts and methods for heating water are provided. A tank is provided for holding water and a heat pump provides heat to water of the tank via a heat exchanger. A variable speed pump pumps water from the tank to the heat exchanger and back to the tank and a three port valve is arranged to provide a flow path from the heat exchanger either to the top of the tank or to the bottom of the tank depending on a flow rate. A controller controls the variable speed pump depending on a hot water demand.
