Thanks for all the replies.

Some of my misconceptions about combi boilers are from here

http://www.gasman.fsbusiness.co.uk/c...on_boilers.htm

Another question - more than one of the people coming to give a quote
have said that a wall mounted boiler isn't going to work with their
single pipe CH and gravity HW system. They currently have a free
standing one. Any ideas why some quotes are saying that?

Thanks

Peter
