Like in my mums house

Nursing homes etc. Or is that exempt as it's not oxygenated in the central heating.

Higher pressure in invented ? CH water isolated from mains ? If secondary return leaks its constant leak ?

I work in loads Simon, and yes they are on a lot, but not 24 hours everyday, maybe the fresh water has an effect too, all I know is what I have seen, not good....

The one round the corner from me do. It's continuous. It's like a bloody oven in there. 9 rooms and 4 flats.

Load of nonsense I've used hep on returns for years with no problems its a lower temp than central heating and the pressure is 3 bar max, another bit of scaremongering about plastic yet again!

Well... No problems until one occurs! Not suggesting that there will be a problem, of course, but if one does, no manufacturer will honour the warranty, and your insurance will be void. It's like any regulation or precaution - it's not there to cover the 99.999% of situations where nothing goes wrong, but the 0.001% of the time when something does...

You make your choice and take the consequences - you're a braver man than me!

Aww maybe I am wrong then, and the manufactures are too, hence why they dont endorse it for this application, must have been the ammonia essence that caused multiple pipe failures......the returns do have to be on 24 hrs a day for this to occur.

I don't hate plastic pipes, indeed it has it merits in some circumstances, but copper all day long for Vern!
