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

No, the pipes are the same, it just looks like TRVs were added and their connection to the rad is 1/2" where the connection to the lock shield is 3/4". I'm not changing the valves, yet, just the rads. Next time the heating system needs drained I'll look at updating the valves.
Also, Tado does not supply valves, just the sensing head.

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?
