When the water is run anywhere in the house the boiler fires up to heat the hot water, but this also seems to trigger the radiator to heat up but the radiator light on the boiler remains unlit.

Can anyone help, when I switch my boiler to hot water only, water heats up fine but every now and then radiators heat up. I have turned off the timer in case this was causing a problem but still no different. No fault lights displaying. :(
