CHG “Condensing, High Efficiency, Gas” Boilers

Today’s lifestyles have created ever increasing demands for abundant supplies of comfortable space heating including radiant
heat, domestic hot water, and snow melting to keep walks and driveways clear – all with the best possible efficiencies available.
A condensing boiler can help ensure that all of these needs are met.

Burnham now offers the best solution for these demanding needs with a ruggedly designed, cast aluminum, condensing boiler
that has efficiency ratings exceeding 94+%. The CHG boiler will meet your family’s heating needs and save you money in energy
operating costs.

94+% Efficiency

Burnham CHG condensing boilers
achieve 94+% efficiency through
our uniquely designed heat engines.
These sectional, cast aluminum
designs use the heat in the exhaust
gases from the boiler’s combustion
process to preheat the water as it
enters the boiler, thus capturing
energy that otherwise would be lost.

Full Modulating Operation

Our CHG boilers are designed to automatically adjust the
firing rate to match your home’s heating needs. With up
to a 5-to-1 turn down ratio, a CHG boiler will continuously
adjust its output to more efficiently and effectively provide
the right amount of heat which further helps conserve fuel
and reduce heating costs.

Potential Annual Fuel Savings

by Increasing Efficiency

Example Savings for:

150,000 Btu Boiler

Gas price at $12.00/Mcf

NOTE - When determining potential savings, all of

these factors must be considered: (1) increased efficiency

rating over previous equipment , (2) new boiler BTU rating,

(3) cost of fuel, and (4) hours per day of full operation.

What is a “condensing” boiler?

When a condensing boiler is working at its peak efficiency,
the water vapor produced in the gas combustion process
condenses back into water – hence the name “condens­ing” boiler. This condensation of exhaust gases releases
the latent heat that is given off when water is vaporized.
Together these two processes, condensation and vaporiza­tion, create the high efficiencies associated with Burnham’s
CHG condensing boilers.

The “Quiet” Boiler

Through its state-of-the-art design, packaging, and unique
combustion process, a CHG boiler operates so quietly
that you may not even “hear” it firing, but you can see its
operating sequence with a digital display mounted on the
top of the boiler.

15-Year Limited Warranty

The aluminum heat engine in our CHG boilers is covered
by a 15-year limited factory warranty. The purchase of an
optional Burnham’s Winter Warmth Assurance program
for your CHG boiler can extend our True Blue Warranty
protection to include parts and labor for the entire boiler
for either 5 or 10 years.

Safety with Increased Efficiency

CHG boilers use a sealed combustion system that isolates
the combustion process in the boiler from the air inside
your home. This design helps save energy dollars by using
outside air, rather than room air you’ve already paid to
heat, and assures that exhaust gases go directly outside.

In addition, the CHG boilers are designed to keep your
heating system running efficiently with Annual Fuel Uti­lization Efficiencies (AFUE) of 94+% which can save you
hundreds of dollars on your annual heating bill.
