Also, for the two I'm looking at replacing, the lock shield valve is 3/4" and the TRV is 1/2". Would a new rad come with multiple couplings or do I need to buy an adaptor/different coupling for either side? If so, what?
So one pipes 15mm and the other 22mm. Weird way to pipe something. Rads don’t come with valves usually and they are extra. I’d personally reduce the 22 under the floor and make them both 15! Danfoss twin packs although there seems to be mad love for they bloody tado things on here
