Abstract (en)

[origin: EP0943877A2] A domestic water heater (1) for use with a domestic water boiler (3) is provided. The heater (1) has usually more than one electrical heating element and preferably three which increase the total heating capacity by forty percent or so. The heater (1) comes into operation when the draw off from the boiler (3) exceeds a flow rate of 8 litres per minute or so and the temperature of the water falls below an acceptable output temperature. It is particularly useful for Combi boilers which are demand draw off combination central heating and domestic hot water supply boilers with relatively little hot water storage capacity. <IMAGE>
