Who honestly sits on plumbing forums at 8am on a Saturday morning making sarcastic comments? *rolls eyes*

Yes that's a fair point I hadn't considered. Of it did blow up. How likely is that though?

Yes I know it invalidates the warranty. And I know the recommended operating pressure is 3 bar. But on a large unvented system (3 showers, 4 toilets, 4 storey house), if I was to fit a pressure reducing / fluctuations valve with a return / bypass and PVR and set it to 4 bar to match the mains...

I've also investigated a Stuart Turner flomate pump but I would still be restricted by the operating pressure in the cylinder. The problem is the height of the house. The water has to travel 4 floors so my understanding would be more pressure would help increase flow rate to the showers on 2nd...

Thanks will do

So will a Tempest steel cylinder not operate at 4.5 bar even though it's been pressure tested at 15 bar? I ain't moving my whole set up upstairs but cheers for the advice!

The cellar has steps going up to the garden so the pipe for the safety relief discharge is drilled through the wall into a drain outside. Boiler, tank and expansion vessel are all in the cellar (which is tanked etc).
