Piping layouts to avoid in hydronic systems - HPAC Magazine

Properly designed primary/secondary systems work. Still in my opinion there are better options that provide the benefits of primary/secondary piping but with simpler and less expensive piping configurations (as shown in Figure 3).. This system connects the boilers to a header system that leads to a hydraulic separator.

Understanding primary-secondary pumping

Jun 23 2014 · The secondary circulators use the common piping between the primary and secondary circuits as their "compression tank." Always pipe your secondary circulators so they pump away from the primary loop and toward the radiation. On most jobs you'll connect your secondary circuits in a manifold off the two primary-to-secondary tees.
