Last night I had a warm but not hot shower, this morning the hot tap ran water that was cooler still. There seems to be a slow leak of some sort around the base of the cylinder as the wood it sits on is a little damp (no pools of water). Last power bill was normal so is either a recent event or very slow fault. We turned it off at the mains to slow down any further trouble in the morning, then the landlord came over after lunch and turned it on, and turned it up to see if it would heat. The pipes and the water are now hot again. Am yet to have a shower and see if it can do it again.
What would cause a) a leak by itself in a 5 year old tank and b) the water to not heat in the first place but to work again later or c)both ? Does anyone know about these?
:dunno:
