Our central heating is switched off, hot water comes on once a day for 1 hour.

Hi , can you tell me what boiler you have , if you have a room stat, a hot water tank , a cylinder thermostat, and if you have any motorised valves?. If you google motorised valve you will be able to see what they look like

Hi, It;'s a Worcester greenstar combi boiler, yes there is a room stat situated in the kitchen, water tank is situated in bathroom it has a sticker which says "Hercal Coil Indirect Cylinder", no motorised valves. Hope this info ok

Hi . it will be a problem with the diverter valve . it should move completely over to the hot water side , but must not be . thgevalve itself might be stuck or just the diverter valve motorised head. Take off the diverter valve head and check that it is moving when heating is put on and moves the other way when a hot tap is turned on
