Abstract

The water heating system 1 comprises a thermal store 3 containing a fluid such as water; a first heat exchanger 5 to heat mains water 19 using the fluid; a first pump 7 to circulate the fluid through the first heat exchanger; and a pump speed controller 9. The pump speed controller progressively controls the speed of the pump in response to a flow rate of mains water passing through the heat exchanger, which may be measured by a flow sensor 11. Ideally, the pump speed is proportional to the flow rate of the mains water and the pump speed is additionally controlled based upon the temperature of the heated mains water 21 as measured by a temperature sensor 13, possibly using pulse-width modulation (PWM). The heated mains water can be used for domestic hot water applications such as taps or showers. The thermal store fluid can be indirectly heated by a second heat exchanger 29 having connections 37,39 to a boiler. The system is quicker to respond to pressure variations in the mains water than similar systems that only use temperature measurements to control pump speed.
