BIMINI BUDDY
HYDRAULIC SEPARATOR
Designed to be installed with any
wall-mounted Bimini boiler.
Introducing the New Bimini Buddy
The Bimini Buddy is designed to be installed with any
wall-mounted Bimini boiler and includes all near boiler
piping needed for good hydraulic separation and air
elimination in a compact factory assembled package. In
addition, some models include provisions for domestic
hot water production.
The BB100I and BB100C models utilize the circulator
that comes with a Bimini boiler, so a separate circulator
isn’t required. They also include a three way zone valve
for domestic hot water priority that is wired directly to
the Bimini without the use of any additional controls.
All Bimini Buddies come with an attractive jacket and
convenient connections for the boiler system, air vent,
and expansion tank.
Three Bimini Buddy Models
BB100H - For heat only applications.
BB100I - For connection of a Bimini boiler
to a heating system and an indirect water
heater like the Mega-Stor®
BB100C - Combi unit with a plate heat
exchanger and flow switch for domestic
hot water production in tight places.
