I have done it commercially loads of times .kop

Lovely. Once installed i will force system over 3 bar in a few scenarios to prove it discharges anyway

Thanks again

Crikey that’s was some read!!
I teed in a prv to outside on a system where the boiler was located in a cellar below ground, spoke to vaillant who told me to blank off the boiler prv and install remotely then leave a sign on the front of the boiler.

I can't see any issue either, it's only like Baxi's remote PRV kit they sell. As long as the PRV is on the system and cannot be isolated from the boiler by the means of isolation valves then I don't see any issues.

In answer to the OP, stating the obvious I know, but the boiler is the heat source and should be the perfect point in system for installing a PRV.
On a system or combi boiler the PRV part of the boiler anyhow.
The expansion vessel kits are irrelevant.
