Agile said:Although its quite easy to work out the predicted pipe loss with a different gas flow rate I expect only a very few CORGi people will be able to do it.

Agile said:By coincidence I met the proprietor of C & R Plumbing yesterday at the Viessmann boiler company.
He is based in Bath and certainly should know how to do it ! If he doesn't then he will know where to ask.

NickStone said:OK Folks, my plumbing and heating guy came out to look at the property today. He didn't measure any pressures and when I mentioned my concerns to him re the combi he said that the reason BG wouldn't fit one is because their boilers rely on positive pressure. The one he recommended was a Baxi Potterton, which he claims, sucks the gas out through the pipe. This sounded very convincing to me, but of course, I know nothing about gas. What do you experts think? As always, many thanks.
gas4you said:What a load of carp If the gas isn't there to 'suck' how can it suck it in. The only sucking in being done here is that of you by your proposed installer. Dump him fast. Sums him up if he is proposing a Baxi/Potterton anyway.
All new combis need the same inlet pressure to work, they are all set up to work on a 20mbar inlet pressure, whatever make.
