Low Mass Piping
When installing low mass systems, additional water mass
may be required to avoid short cycling by the boiler. In
these applications it is recommended that a buffer tank be
installed.
Note
:
• DHW piping not shown for clarity. Reference applicable sections of this
manual for DHW piping details.
