Figure 3 - Two Zone Boiler Piping With Zone Valves
NEAR BOILER PIPING
Multi-Zone Systems
Multi-zone systems with two zones are typically piped as
shown in Figures 3 or 4. Multi-zone systems with more than
two zones are likely to have small zones with very low heat
and
fl
ow requirements compared to full heating capacity of
the boiler. This can result in very low
fl
ow in the boiler if
only one small zone is calling for heat.
Primary Secondary Piping is recommended for multi-zone
systems with more than two zones to insure proper water
fl
ow through the boiler at all times. See Figures 5, 6 and 7
for typical primary secondary piping con
fi
gurations.
