When the hot water switch (on the Honeywell controller (from where the timings for the central heating and hot water are set)) is activated, the pilot light in the boiler burns fully and heats the water up just fine. It is only when the hot water is switched on like this that the central heating will kick in. The central heating DOES NOT work independantly of the hot water and this is my concern.
With winter on the horizon I will be having the central heating on for hours and hours and therefore the hot water will be burning away for hours and hours. Does this sound correct i.e. if the central heating is on for say 5 hours that the flame in the boiler should be burning fully for 5 hours (and therefore be constantly heating the water for 5 hours)? Is there any way to make the central heating and water work independantly. I have read about zone valves? Can they be installed? Any advice would be greatly appreciated. Thank you.
