1| Boiler Buddy® Installation Manual
The Boiler Buddy is available
in 18, 30, 80, 50 and 119 gallon
capacities. It is designed to be
used in heating systems with
low-mass boilers, geothermal,
chilled water applications, or
low-mass radiation. Boilers
operating at low loads may
short cycle which can lead to
sooting, premature component
failure (nuisance lockouts) and
ineciency.
The Boiler Buddy tank is a
factory insulated (polyurethane
foam) and jacketed storage tank,
adding mass to the system and
providing the necessary buer
to prevent short cycling. If the
boiler ring cycle is extended for
a minimum of several minutes,
the full eciency of the boiler
can be achieved and nuisance
problems can be avoided.
The Boiler Buddy also creates
a low velocity state within
the system, providing air
elimination, assisting in the
removal of sediment and
debris, and acting as a hydraulic
separator between required
ows from the boiler(s) and the
multiple ow rates needed for
the secondary zones. The ball
drain for sediment removal also
acts as an excellent way to fast
ll the system.
Excessive draining from
the Boiler Buddy is not
recommended, as it introduces
more contaminants into the
system. Routine maintenance
of the closed-loop system
should be performed
once per year, or sooner
as per boiler manufacturer
recommendations.
Note: Boiler Buddy buer tanks
are not for use with potable
water!
