BUDERUS
Cast Iron Boilers
G215 – G315 Series
Domestic hot water tanks
The Buderus indirect fired domestic hot water tanks are designed to fit any
specialized need. To maximize space, you are able to pair the LT-tanks with the G215
stacked on top. For greater recovery rates, you have the option of pairing the boilers
with vertical model tanks. These tanks increase boiler efficiency, system longevity
and minimize the need of service calls, when paired with a Buderus boiler. The tanks
are designed with many features to aid in maintenance, such as easy access ports
for cleaning the tank’s interior, extra thick Magnesium anode rods and Thermoglaze
®
interior tank coating to protect against corrosion and aid in cleaning. To help maximize
efficiency our tanks are extremely well insulated to minimize stand-by heat loss.
Convenient Logamatic Control
The Buderus Logamatic Controls, designed to work with all Buderus boilers,
significantly increase the efficiency of your heating system. The Controls maintain a
comfortable environment by measuring indoor and outdoor temperatures in order to
automatically and effectively regulate the temperature of the boiler. This allows the
boiler to use less fuel while keeping your home exactly as warm as you want it. The
Logamatic Controls also include the convenience of a setback feature for nighttime as
well as a domestic hot water priority option. So, no matter how hard the heating has
to work on a cold day, there will always be hot water for showers. All control functions
are able to be customized by you. Additionally, the Buderus Logamatic R2107 is
designed with a built-in self diagnostic system to aid in maintenance and reduce
service costs.
Maintenance and service convenience
Stack temperature is easily adjustable with the removable baffles. A full swing
reversible burner door allows maximum accessibility, and allows the boiler to be
located almost anywhere. Buderus boilers are designed to be fully serviced from the
front without disassembly and thus can be serviced in half the time of competitor’s
boilers. The Buderus GL-180 cast iron breaching helps ensure a long, trouble-free life.

How it works
The flame fires into the first chamber.
Then the flue products flow through
the second pass to the front of
the boiler. From there they reverse
direction again—moving through the
third pass to the back, and finally
exiting via the flue connection into the
chimney. Because the gases are held
in the boiler longer this allows the cast
iron to absorb the maximum amount
of heat, resulting in a lower stack
temperature and a higher efficiency.

The three-pass boiler is designed for
❚ Optimized combustion with
positive pressure-fired boilers
and tailored chamber geometry—
no need for a heat-consuming
refractory or target wall eliminating
the need for costly repairs.
❚ Minimal stack losses with the
modified three-pass flue design’s
large heat transfer areas.
❚ Low standby losses with a full 3½"
to 4" jacket of thermal insulation
around the entire block—even
underneath the boiler!
