We have recently had a problem with the Central Heating system, the Rads are now working perfectly, the boiler comes on the timer, however we have lost our hot water. The boiler is set to Heating & Hot Water, but we have to switch the immersion heater on in the airing cupboard to obtain hot water. Any ideas?

I think this question gets asked on almost a daily basis, you have a problem with motorised valve or your cylinder thermostat.
