This seminar will concentrate on hydronic principals such as the point of no pressure change, the universal hydronic formula, calculating head loss, and pipe sizing. We will examine the principals of primary-secondary piping and the similarities to mono-flow piping. The proper technique to calculate water temperature through the system will be illustrated and you will see why the proper placement of equipment in the system is so important. You will learn the correct piping arrangements that work with today’s high efficiency modulating condensing boilers and why piping like a conventional boiler is a mistake. Approved for 3 NORA CEU’s.
