our floor heating is an open system not under any pressure just gravity and pumped through the floors with an armstong pump. We are going to put a new bigger BTU boiler in and the contractor wants to pressurize it slightly so its a closed system. The only problem is i still have one bay that has 35 year old steel piping in the floor. To pressurize or not to pressurize. If i do it might spring a leak in that one bay, but it is getting old and probably going to replace soon anyway. any suggestions?
