Ensure that the pressure reducing fill valve is set for the same pressure as the air charge in the expansion ...
WebHow to size and select a proper Expansion Tank When water is heated, it expands and its volume increases. Since water is considered non-compressible, in a closed-loop system, this thermal expansion puts an incredible amount of pressure on the piping and components of the entire system. WebFor vented tanks, the pressures are all the same and the dominator limits to 1, so the tank size is simply the volume of expanded water: V t = V e V t = V e Closed Tank (no precharge) For unvented plain steel tanks, the starting pressure is typically atmospheric pressure with the tank empty (no precharge).
