Abstract

An unvented water heater (10), the heater (10) including a water tank (12) to store water, the water tank (12) incorporating a heating element (16) to heat the water, a water inlet pipe (25) to admit mains water into the tank (12) and a discharge pipe (22) enabling excess water to be discharged; the heater including an air-gap regeneration device (20) to introduce air into the tank, the device being operably connected to the inlet pipe (25) and the discharge pipe (22) to open and close said pipes (22, 25), pressure determining means to measure the pressure within the tank (12) and transmission means (23a) to pass the pressure data obtained from the pressure determining means to the device (20), the device (20) operating once the tank pressure has exceeded a pre-set pressure, an air inlet valve (24) admitting air into the tank (12).
