Can anyone tell me how to size a expansion tank to a typical hot water system?....when should i use a #15,30,60,90 etc.....i am having a problem with a mono-flo system, with a #30 extrol...and at least once a month i will be called to the home and the relief valve has blown.....boiler is piped properly(pumping away)....reducing valve is set to 12 psi....extrol tank pressure is at 12psi. I am going to try to put a #60 extrol, to see if that solves it.......
