ABSTRACT:
A central heating system comprising a heat exchanger, heat dissipating means, and a connecting piping circuit for liquid flow, has a pump capable of pumping the liquid around the circuit at a lower or a high flow rate, the flow rate of liquid being sensed to control the means which supplies heat to the heat exchanger so that heat is supplied when the pump means is operating at its higher rate and is not supplied when the pump means is operating at its lower rate. The rate of operation of the pump means is determined by means which senses the temperature of the circulating liquid so that the pump means operates at its lower rate when the temperature of the liquid exceeds a selected value and at its higher rate when the liquid temperature is below a selected value.
