Hi Heatpro, I just want to understand what is the proper amount of air pressure I should have in my bladder type expansion tank for my residential boiler? When you balance the system do you keep the air pressure in the expansion tank the same as the internal pressure of the boiler? I have 12psi in my boiler.
