System Piping
The Apex is designed to be installed in a variety of configurations. Shown here
are four illustrated examples of how the Apex boiler can be piped into new or
existing heating systems. Examples shown here include heat-only applications,
building heat plus domestic hot water, alternate piping of heat plus domestic
hot water, and a multiple boiler installation incorporating domestic hot
water. The Apex provides outstanding flexibility by providing the capability of
controlling up to three system pumps. In addition, an indirect water heater
can be placed in either the primary or secondary loop, further enhancing the
boiler's ability to accommodate a variety of systems.
These illustrations are intended for informational purposes only, and
are not intended for use as near boiler piping diagrams.
For further information on piping requirements, please see the Apex
Installation & Operations Manual.
