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 effi cient

? Today, with those questions still in mind, and a goal of continuous improvement and refi nement, Central Boiler is the largest manufacturer in North America of the best-selling, industryleading outdoor wood furnaces available.

PEACE OF MIND Keep the fi re outside and it eliminates the traditional indoor wood stove hazards. Burning wood indoors is inherently dangerous as there is a threat of a fi 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 fl 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 fi re prevention.

PRESERVES WILDLIFE HABITAT SOIL AND WATER QUALITY

Harvesting wood has a pruning eff ect on forests – planting new trees ensures wildlife will have a healthy habitat.

Reforestation reduces erosion risks and protects watersheds that are a source of the water we drink and use.

AESTHETICS AND RECREATION

Sustainable forestry makes more room for new and healthier growth through reforestation.

REDUCES FOREST FIRES

By harvesting old and dead trees that can easily burn, it can significantly reduce the risks of costly wildfires.

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 firebox and heat exchanger. This heated water is circulated to buildings through insulated underground pipes which is a highly efficient 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 floor 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 off.

HEAT MULTIPLE BUILDINGS Unlike an indoor wood stove, a Central Boiler outdoor wood furnace has the ability to heat multiple buildings such as a 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.

Ultimate Control

The

FireStar™ II Electronic Controller

automatically adjusts the primary and secondary air which optimizes the gasifi cation process allowing the furnace to be more effi cient 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 eff ective R-value of conventional fi berglass batt insulation. Fiberglass batt insulation also settles and compresses over time.

Smart features designed with you in mind.

Convenient operation and choices to fi t your lifestyle.

THE MOST ADVANCED FURNACE

The FireStar II electronic controller comes standard on all E-classic models. The FireStar II electronic controller monitors all functions of the furnace and can store and share operational data. The controller’s technology optimizes the gasifi cation process by automatically adjusting the primary and secondary air for a cleaner and more effi cient burn. Operational data can be utilized with a memory card or on the FireStar™ XP module when connected to the FireStar™ II.

EFFICIENCY MEANS MORE HEAT FROM LESS WOOD

Central Boiler E-Classic outdoor furnaces’ energy effi cient designs maximize the combustion and heat transfer process for better heat delivery. In other words, our outdoor furnaces burn more completely and effi ciently, 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 effi cient 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 fi 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 fi 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 effi cient.

TIME SAVING OPTION

Never start a fi re manually again! The optional Gas-fi red Wood

Ignition Kit is easily installed in minutes without modifi cations 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-fi 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-fi module keeps you in constant contact with your Central Boiler furnace if you’re away. The FireStar

XP wi-fi 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 fi nest wood burning system we have ever had the pleasure of using. The ease of operation, the effi ciency, 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 house and heat water for a family of 6. I haven't used a drop of fuel oil since and have even turned off the breaker to the water heater.

- Lee, 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

The best decision I ever made was

- Matt, MI

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

We purchased our Central Boiler last

December and we love it! I sometimes fi nd myself saying I wish I had it 10 years ago. Thanks.

- Barry, TN

I have been an owner of a Central money saver over these many years.

-Randal, MN

This is my second winter with the that I didn’t buy it sooner.

- David, IL

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 fi 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

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 effi ciency 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.
