sizing a pressure vessel

cristoforo · 13 Dec 2006

Hi guys how do i size a pressure vessel for a combi boiler? I think the one I have now is to small and what would happen if the one i put on was too big?

There are a few simple rules, generally on size of the system, pump head used etc. Normally if you have the MIs to hand or can get them it will state what you require.

thanks gas2air but what would the outcome be if i put one on that was too big?

No downside at all. Put it on the return pipe just before the boiler.

Why do you think its too small, are we having problems

Most combis use 6 or 8 litres.
