Been to a job today, what a mess! Can anyone advise me why any1 would put a gas arger on a y plan? Destructions say it needs a permanent feed to pump which it has but once cylinder is satisfied the cylinder becomes a thermal store to the curcs. There is even a rad on the curcs piped like a bypass (after pump/ return in into cylinder return. 
Apart from a s plan has any1 any ideas?
