We discovered a problem this morning which hasn't been noticed before. We do not have the central heating on but the boiler is programmed to come on for hot water only for two hours in the morning.
The boiler is situated downstairs, but pump, valves and hot water tank are upstairs. With only the hot water programmed to be on, not the central heating, the upstairs radiators are becoming hot.
Could anyone explain why this should be
Thanks
Ann
