A heating system is provided. The heating system includes a heat pump to provide heat. The heating system includes a circuit of heat transfer fluid to transfer heat to or from the heat pump. The heating system includes a space heating system configured to transfer heat from the heat transfer fluid to an environment. The heating system includes a water heating system comprising a water tank for storing hot water to be provided to a user, a cold water inlet, a hot water outlet for drawing off hot water for supply to a user, and a heat exchanger configured to exchange heat between the heat transfer fluid and water from the cold water inlet. The heating system includes a means of sensing a tank status, the tank status being indicative of a quantity of thermal energy stored in the tank. The heating system includes a controller adapted to control the transfer of heat to and from the tank in dependence on the tank status.
