| have a Baxi Combi 80Eco when the hot water tap is turned on it takes a while for the boiler to fire up and give hot water .
I have increased the mains pressure, and reset the boiler pressure to the correct bar. But it is still the same. All sugestions to cure this problem gratefully received.
Regards
Traced the problem to a split diaphram in the Pressure Differencial Assembly. Replaced the diaphram only, not the whole assembly. The assembly £55 diaphram £2, not bad eh !!
