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： A controller interface (B12) between a hot water tank controller (B13) and a heat pump controller (B2) in a heating system is provided. The controller interface (B12) comprises a response module configured to receive, from the hot water tank controller (B13), a first signal indicative of a temperature. The response module provides a response signal based on the first signal and a temperature response characteristic and communicates the response signal to the heat pump controller (B2). The controller interface (B12) enables interoperability of a heat pump controller (B2) and a legacy hot water tank system and hot water tank controller (B13).
