WebThe air charge of the tank should be the same as the desired system pressure. Once the air charge is set, open the system isolation valve and the pressure from the system and expansion tank will equalize, filling the bladder with water. Ensure that the pressure reducing fill valve is set for the same pressure as the air charge in the expansion ... WebNov 11, 2014 · First, determine the total system volume, including the heater, the piping, the user and the initial-fill volume of the expansion tank (the amount of thermal fluid required to meet the minimum level in the tank. Combined, these amount to every single drop of thermal fluid in the system.
