Taco Tuesday: Expansion Tank Design and Sizing / Pumping Away

The most critical element of boiler piping is that short stretch from the boiler outlet to the outlet side of the circulator(s). In this fast-paced, fact-filled hour, Taco will discuss the mystery of residential expansion tank sizing, what makes the Point of No Pressure Change important, and why pumping away from the Point of No Pressure Change can help control air and ensure proper system flow. You’ll also learn why older systems with the circulator on the return side of the boiler work well, even though those circulators do pump toward the Point of No Pressure Change.
