Thanks guys, you have answered my queries. Hot water flow is important to me so I think I'll go with a conventional Vaillant combi. New boiler installs aren't cheap so it was worth asking before we installed and later regretted!

Pressure drop is relative to flow rate though, so it must be given against a flow rate or with a curve

Thanks for the replies. The graph shows pressure drop across the boiler which will affect the resultant flow rate as you need pressure at the outlet to get some flow. Essentially dropping 2 bar across the hx would leave you with 1 bar in the pipe which would be as poor a flow rate as just having...

I've been looking into getting an Intergas 36/30 fitted at my house by a local installer, however I am an engineer so naturally interested in the specs and workings of these things. Now the questions I cannot find an answer to is this: Intergas's datasheet shown a pressure drop curve for...
