A hot water heating system which includes a storage tank with a specially arranged heat exchanger therein, together with at least one blending valve and a valve for controlling the heat supply to the heat exchanger, and also including a fluid connection whereby a change in demand for blended hot water from the blending valve causes an instantaneous change in the heat supplied to the tank which is proportional to the change in demand and takes place before any material change in the temperature of the water flowing from the tank to the hot water blending valve.
