Quick question, I had a combi boiler installed in replacement for a back boiler a few years ago, in addition to that work the plumbers installed an additional rad in the living room, using the grey speedfit parts then copper pipe when the piping went visible.
I'm going to move the radiator now and so i'll be changing a few things on it.
what i was thinking though was could i add 2 isolation valves on this plactic speedfit so in future if i need to remove/move anything below it, i can isolated it without having to drain the whole system.

but i've been checking plastic isolation type fittings and they all say only suitable upto 65 degrees
but as far as i'm aware the standard flow of a central heating system is 75 out 65 return?
can anyone provide a link to a suitable isolation valve
