This is all extremely useful, esp. as, if I can afford it, I would
also like to move the boiler in the (unfloored) loft.

I should say that Broag (Remeha) emailed me back within a day with the
details of a local installer that does their range.

It will be interesting when the time comes for me. I think the
challenge is to find a recommended fitter who supports the improved
controls and features (and even more basic things, like combi vs
system), while offering a personal service. In the meanwhile I will
keep collecting information.

Many thanks!
