Majorca Gloworm back Boiler with Radiant Convector Fire, boiler thermostat set at 160C - Randall 4033 Control unit under stair - Honewell thermostat in hall. Hot water tank upstairs. Electric pump.

When the hot water becomes hot the heating of the radiators stops, bolier burner switches off. Turning up/on/off thermostat in hall does not start heating of the radiators . If I run off some of the hot water then the boiler kicks in and starts heating the radiators.? :confused:
