Bladder math ... is 4 % expansion on water 65-180f the right math? I have 185 gallons total in system and that works out to 7.4 gallon expansion
at 65f I have a empty bladder and at 170f its almost full . It says in book tire tube ( bladder hold 8 gallons ) .. Is that 4% expansion.
Right ? The bad part at start up in fall I can not tell where the water level is because bladders empty at 65f .. How does everyone else do it ? I can fire it to 100f and make sure there's water in bladder . Must be the way to do it. my old 200css Did not have as much water so it always had water in bladder at 65 f . :thumbup:

I close bladder and top boiler off, then open bladder and fire up.
