Ah, do alot of the newer ones have 4.5bar pressure relief valves?

Ah, be interesting to see what bar most unvented cylinders are these days.

Is this while it appears most manufacturers are supplying/specifing bigger expansion vessels now. As the cylinders are rated to a lower pressure?

Excellent answer explains it well!

Thanks I think it said on the cylinder rated to 10 bar.

So if 250litres of water will only have an expansion volume of 5 litres. Why are some manufacturers asking for a 25litre vessel on an 250 litre cylinder?

On that one they have tee'd in for the expansion on the balanced cold.

The expansion is tee'd in after the pressure reducing valve

Could I not just renew the pressure relief on it?

Which I now believe have been taken over by kingspan Albion

The cylinder make is RMC group ultrasteel cylinders
