Firstly a big hello! This is my first post on here, not sure how much I can offer in terms of advice...although as my experience with these things grow... Anyway, I was wondering if anyone out there can shed a little light on a problem I am having with the above boiler. We seem to be getting hot water intermitantly - we seem to get plenty of hot water throughout certain times in the day but have noticed, more so on mornings, that the water will run hot for a while and then just run cold... with no further hot water coming through. However we can run, for example, a bath full of hot water at another point without issue(!). Just wondering if there is something I'm missing here on the setup etc. I openly admit I am fairly ignorant with regards gas central heating systems (although I learning fairly rapidly at the moment) , and the house we just moved into a couple of weeks back is our first to have GCH (all electric houses before this with night storage etc) - so I guess the fun and bills begin now (!).
