Boiler Pressure Problem

It'll be interesting to hear what the W/B have to say about the potential supply to your house if you upgrade your supply pipe - I hope they have this info and it's reliable.

You should be looking at 20lpm min, and in excess of 2 bar. You ideally want MORE than this, tho'. If uncertain, go 'pumped accumulator'. That will give you the best possible results, and should also minimise one of the combi's biggest issues - the way the flow drops when you open another tap/flush a loo...
