    We recently installed some underfloor heating for a customer. I've not done it before so enlisted some help of another plumber friend of mine.

    Problem. Heating only = fine.
    CH and ufh= fine
    Ufh only = brings ch on too and can't be switched off on the room stat and rads get extremely hot.

    I've not had a chance to get back but any ideas? We put a 2 port in for the Ufh as there wasn't one supplied with the pack.

    Morning,

    have you got another 2 port zone valve installed for the CH?

    Thanks,

    Have you zoned the UFH and CH with 2 zone valves, 2 room stats and a 2 channel programmer?
