Basically, i have a hot water tank up in the loft when its summer the tank gets hot, and i have hot water from the taps. However during colder months i try and turn the water temp on the boiler to the max, i heat it up for 2 hours and it does nothing. However when the heating knob is turned up higher the water gets warmer. Obviously i dont want the heating turned up higher so that the water can heat up. Ive read on a separate forum that valliant made these boilers with both tap and radiator symbols for combi boilers as well. Any suggestions?
Cheers.
