Does this make sense ?
This is a standard open-vent, pumped heating, gravity h/w system with feed and expansion pipes each side of h/w cylinder.
The measured water expansion (in header tank) is approx' 4 litres. ie. the level in the header tank rises by 4 litres as the system heats up. The volume of water in feed pipe is approx' 0.5 litres (3m x 15mm pipe).
Does this mean that every time the system cools down then 3.5 litres of aerated water enters the system ?. If so, how much air might this produce ?
Thanks, pcr.
