hello - need to bleed the radiators and have some questions please
my system heats a smaller single story home, the boiler pumps hot water out to a "T" where it goes on to feed 4 old cast iron type radiators in series on each side of the house (8 radiators total, 4 on each side, 2 independent legs simultaneously being supplied from the "T") there is also a circulation pump in the system.
1)does the system need to be on and water in circulation during the process?
2)if circulation is not necessary should the system be hot or cold? does it matter?
3)which radiator should be done first? the one farthest from the boiler or the one closest?
4)which leg should be done first? i am assuming based on the system layout it does not matter
To bleed the radiators just make sure the boiler has pressure....you shouldn't need much on a single story home factory set 12psi from reducing valve should be fine....I would have the system off when bleeding the radiators....hot or cold doesn't make a difference....do you always have air problems? And you can start with any radiator.....Paul s
