Boiler-side piping (continued)

Figure 8 Zoning with circulators — primary/secondary system piping

Notes

Place circulators at begin- nings of zones. Placing them at the ends of zones could result in heating idle zones.

Size manifold piping for total flow of all zone cir- culators.

Locate flow / check valves as close as possible to water heater boiler side connec- tions — to reduce heat loss between cycles.
