We have a heating system which consists of boiler and hot and cold water tanks. Been working fine for a month now (moved in to new place month ago) and then this morning wake up and only luke warm water coming out of hot tap. Pressure fine on both hot and cold taps but just doesn't get hot. No matter which tap i use. Shower is the same (not an electric shower). Is this an airlock, or is it not because water is actually coming out of the tap?
Thanks
