Hi All -
Having an issue with my NCB 240 combi boiler that I'm hoping someone can help with.
The boiler is not recognizing a call for hot water from our kitchen sink however this only happens when we have the radiant heat in the basement turned on and both sides of the boiler active. The strange thing is if I go to the basement and turn on the hot water in the laundry room sink (which is only a few feet from the boiler) the hot water will work there but then will also work in the kitchen sink afterwards. Also the kitchen issue seems to happen most frequently first thing in the morning after we wake up and haven't been running water in the house for several hours.
I'm fairly handy and would like to address this myself before paying for someone to come out if possible. I'm guessing it's either a pressure issue at the kitchen sink (although the water pressure is perfectly fine) or there is a part in the boiler which is supposed to recognize/prioritize DHW that is going bad.
Any help here would be very much appreciated.
Thanks!
Charlie
