Welcome to the best way to heat with wood.
Welcome to Central Boiler.
Your reasons for heating with wood are likely the same reasons
Central Boiler was founded in 1984. But rather than just develop
another way to heat with wood, Central Boiler set out to develop
better ways to heat with wood. They dared ask the tough questions:
can heating with wood be safer, less time-consuming, cleaner
and more ecient? Today, with those questions still in mind, and a
goal of continuous improvement and renement, Central Boiler is the
largest manufacturer in North America of the best-selling, industry-
leading outdoor wood furnaces available.
PEACE OF MIND Keep the re outside and it
eliminates the traditional indoor wood stove
hazards. Burning wood indoors is inherently
dangerous as there is a threat of a re and
carbon monoxide buildup.
IMPROVED INDOOR ENVIRONMENT The mess stays
outside with a Central Boiler outdoor wood furnace.
Anyone that has burned wood inside is familiar with
the smoke, ashes, odors and soot that often occur. In
addition, bringing wood indoors can bring unwanted
bugs, bark and dirt.
FREEDOM TO DO MORE Those that choose to heat
with wood often do so because of the cost savings.
With a Central Boiler outdoor wood furnace, it can
take less wood to heat more space, so no matter what
your costs and time are associated with acquiring your
wood supply, using less wood means you’ll have more
time (plus save more money!) to do other things.
STABILITY Wood is usually sourced locally.
Conventional heat sources like propane, natural
gas and fuel oil will always be susceptible to price
uctuations and are irreplaceable fossil fuels.
Historically, the price of electricity trends only upward.
SUSTAINABILITY Harvesting wood with sustainable
forestry practices helps to maintain a healthy
ecosystem for wildlife habitats, aesthetics, soil and
water quality, native biological diversity, recreational
opportunities and re prevention.
PRESERVES WILDLIFE HABITAT AESTHETICS AND RECREATIONSOIL AND WATER QUALITY REDUCES FOREST FIRES
Harvesting wood has a pruning eect
on forests – planting new trees ensures
wildlife will have a healthy habitat.
Sustainable forestry makes more room
for new and healthier growth through
reforestation.
By harvesting old and dead trees that can
easily burn, it can signicantly reduce the
risks of costly wildres.
Reforestation reduces erosion risks and
protects watersheds that are a source of
the water we drink and use.
“It’s the right thing to do!”

Installing your Central Boiler outdoor furnace
is easier than you might think. Many customers
choose to install their own furnace because the
installation can be easily completed using the
installation manual. Authorized Central Boiler
dealers have all the supplies and accessories
you need for installation and maintenance. All
of our dealers can provide you with information
regarding your installation, and most dealers can
even handle the entire installation for you.

Sophisticated, yet simple.
How a Central Boiler outdoor wood
furnace works.
While a Central Boiler outdoor wood furnace is one of the most
sophisticated, technologically advanced ways to heat with wood,
how it heats is a pretty simple idea. A Central Boiler outdoor wood
furnace burns wood to heat water. The heated water is circulated
through insulated underground pipes called ThermoPEX to the
buildings being heated. Heated water can transfer its heat energy
by direct circulation or by moving through one or more heat
exchangers, or both.
LOCATION The Central Boiler outdoor wood furnace is located
outside, typically 30 to 200 feet (but as far as 500 feet) away.
CIRCULATION The furnace contains a high volume of water that
surrounds the furnace rebox and heat exchanger. This heated
water is circulated to buildings through insulated underground
pipes which is a highly ecient way to move heat over distances.
INTEGRATION Central Boiler outdoor wood furnaces are
designed to work with your existing heating system. Water-to-air
or water-to-water heat exchangers or direct circulation conveys
the heat into the structure’s forced-air furnace, radiant baseboard
or radiant oor heating system. This allows you to control the heat
simply with your thermostat.
UNLIMITED HOT WATER When you install a heat exchanger on
your domestic water heater, you can enjoy unlimited hot water
and the savings from turning your water heater o.
HEAT MULTIPLE BUILDINGS Unlike an indoor wood stove,
a Central Boiler outdoor wood furnace has the ability to heat
multiple buildings such as a house, garage, workshop, shed,
greenhouse or barn. It can even be used to heat a swimming pool
or hot tub.
Installation is a breeze.
Connect the piping and heat exchangers to your existing heating
system and the E-Classic is ready to go to work.

E High Eciency
Final combustion takes place as these gases move downward
through the Fusion Combustor to the Reaction Chamber where
extremely high temperatures aid in complete combustion. This entire
process results in high eciency and extremely low emissions.
F Operational Convenience
Bypass Door allows you to redirect the exhaust before
opening the rebox door. The Bypass Door Alarm reminds
you to close the bypass door after you have closed the
rebox door for ecient operation of your furnace.
G Easy Loading
This triple insulated rebox door is just the right height and
features a large opening for easy loading, making your job much
easier. The ergonomically designed, lockable door features a
Cam Loc door closure that secures the door at all four corners and
provides a tight seal each time the door is closed. Its triple insulation
keeps the heat in and the cold out for maximum eciency.
H LED Lights
( Photo Electronic Controlled)
The long-lasting, energy ecient LED lights save money
and enhance safety. They illuminate the inside of the rebox
and the front and sides of the outdoor furnace and can be
set to conveniently, automatically turn on at night.
I Easy Ignition Option
The optional gas-red wood ignition takes the work and worry out of
lighting a re. With just the push of a button, the power ignition will light
the re. It will also automatically relight the re if needed, even when you
are away from home. It is just that easy.
A Ultimate Control
The FireStar™ II Electronic Controller automatically adjusts
the primary and secondary air which optimizes the gasication
process allowing the furnace to be more ecient and cleaner
burning. It is capable of data collection with the ability to
communicate with other devices, and provides the user with
easy operation of the furnace with just the touch of a button.
B Less Maintenance
The Xtract® Heat Exchanger allows you to get the most heat
out of your wood. It is designed to optimize the transfer of heat
from the extremely hot gases to the water. The vertical design of
the heat exchanger allows any small particles in the exhaust to
drop to the bottom. They are easy to clean out from the Reaction
Chamber. This minimizes the amount of maintenance.
C Burns Less Wood
A hallmark of Central Boiler furnaces for over 30 years, spray-on
urethane is the ultimate airtight, waterproof insulation that
locks the heat in to reduce wood usage, even at temperatures
of -35˚F or colder. It provides 2-3 times the eective R-value
of conventional berglass batt insulation. Fiberglass batt
insulation also settles and compresses over time.
D Performance
Patented Air Charge Tube adds air in all the right places
to aid in the combustion process and keeps the coals from
falling through into the lower Reaction Chamber.

EFFICIENCY MEANS MORE HEAT FROM LESS WOOD
Central Boiler E-Classic outdoor furnaces’ energy ecient designs
maximize the combustion and heat transfer process for better heat
delivery. In other words, our outdoor furnaces burn more completely
and eciently, and transfer more of the heat generated to your home.
Current owners of E-Classic outdoor furnaces report that they are using
up to 25% to 70% less wood compared to traditional wood furnaces
or other brands of outdoor wood furnaces. Indoor wood stoves can
be less ecient because heated indoor air used for combustion is
sent out the chimney, causing cold air to be drawn into the house
to replace it. Indoor wood stoves can also overheat the room.
BURN WOOD, NOT YOUR SPARE TIME.
Continuous stoking of wood is a necessary part of replace and
wood stove use. If you don’t have the time or energy to continually
babysit these heat sources, a Central Boiler outdoor furnace is your
low-maintenance alternative. Since Central Boiler outdoor wood
furnaces can burn larger pieces of wood they can dramatically
reduce time spent preparing the wood. The large rebox door
is designed for easy loading of wood and removal of ash.
INSULATED REAR ACCESS PANEL
This panel swings open giving you full
access to the Reaction Chamber door, power
disconnect and pumps, all from one location.
That makes installation and
maintenance convenient and
easy. The insulated panel
keeps the heat in and the
cold out, which preheats the
combustion air and makes
the furnace more ecient.
TIME SAVING OPTION
Never start a re manually again! The optional Gas-red Wood
Ignition Kit is easily installed in minutes without modications and
gives you the convenience of easy push-button lighting of the wood
with the added convenience of automatic relighting if needed. The
propane burner is standard. A natural gas conversion kit is available.
Kit is pre-assembled and easy to install no wiring needed.
Available for all E-Classic Ignition Ready (IR) models, the Gas-red
Wood Ignition Kit is available from your Central Boiler dealer.
STAYING CONNECTED
Stay connected to the furnace that saves you money on your heating bills from
almost anywhere in the world. Adding the FireStar XP wi- module keeps you
in constant contact with your Central Boiler furnace if you’re away. The FireStar
XP wi- module can send you reminders such as when to add wood.

What Central Boiler owners say.
“
Our new Central Boiler system
is without a doubt the nest wood
burning system we have ever had
the pleasure of using. The ease of
operation, the eciency, safety and
the end result of a steady, dependable
heat source provided by our Central
Boiler stove surpass anything we have
encountered in the past 50 years of
wood burning as a heat source.
”
- Justin, MN
“
I installed a Central Boiler 2 years
ago. I heat a 2,500 square foot farm
house and heat water for a family of 6. I
haven't used a drop of fuel oil since and
have even turned o the breaker to the
water heater.
”
- Lee, MI
“
I have been an owner of a Central
Boiler since 1992. It has been a great
money saver over these many years.
”
-Randal, MN
“
I think that the Central Boiler should
be rated a 12 on a 1 out of 10. This is
such a wonderful product, no home
should be without one.
”
- David, OH
“
This is my second winter with the
Central Boiler and my only regret is
that I didn’t buy it sooner.
”
- David, IL
“
This is the fourth year I have owned
my Central Boiler and I have to say, it
may very well be the best investment I
have ever made. The furnace has paid
for itself. I continue to be impressed
with the quality and eciency of the
Central Boiler product, the simplicity
of maintenance, and the excellent
dealer support I receive. I have
recommended your product to many
people and will continue to do so, as
I truly believe it is superior to your
competitors.
”
- John, WV
“
I load it once a day and forget
about it. It is so much more convenient
than having to constantly load the
indoor wood burner and I am using
about half the wood. I am more at ease
with the re outside away from the
house along with the dust, bugs and
ash. It has also been nice not having to
hear the propane hot water heater run
at all. The unit is nicely constructed and
blends in with the surroundings out in
the yard.
”
- Lucas, NC
“
The best decision I ever made was
purchasing my Central Boiler.
”
- Matt, MI
“
I recently bought an E-Classic, when
the heater arrived I was skeptical that it
could heat my entire house! My home is
8,000 plus square feet, well I'm happy to
say I was wrong! This thing is amazing!
I was on heating oil, and in the dead
of winter I was burning about $1,600
a month in heating oil and propane to
heat my house and hot water! I now
have more hot water than I know what
to do with! And my cost savings are
out of this world! I'm going through a
cord of wood a week at $125 a cord so
that's $500 per month compared to
the $1,600 I was spending! I know this
sounds too good to be true but it is!
”
- Thad, AK
“
We purchased our Central Boiler last
December and we love it! I sometimes
nd myself saying I wish I had it 10 years
ago. Thanks.
