    Yes, I know.  It's just that the picture brought it home to me very powerfully; all that water, right on the doorstep!

    Really comes down to how much piping will need to be laid for our 1400 sq foot semi detached

    It's just the kitchen, the living room (pictured) and a toilet but yes, the entire floor run off 3 ports on the manifold. We were just about able to use a 3 port polypipe manifold.

    I wouldn't cover them, I'd lacquer them then add some clip-on temperature guages for the full Steampunk effect :D

    What is the massive shunt between the heating flow and return?

    Part of me wishes that rather than the isolator switch I had put in a plug on the boiler supply into a socket so that I could plug the boiler into the V2L out from the car in the event of a power cut (the viessman has the circulation pump built in)
    I think....
