If you are considering purchasing an outdoor wood furnace, please take a few minutes to read through this information. Central Boiler Classic^®Outdoor Wood Furnaces are unmatched in efficiency, quality, and reputation.

Central Boiler outdoor wood furnaces provide the warmth, comfort and economic advantages of burning wood without the mess, inconvenience and dangers posed by indoor burning.

• Unlike fossil fuels, wood is a totally renewable resource
• Unlike fossil fuels, burning wood results in no net carbon dioxide increase, which is believed to be responsible for the "greenhouse effect."
• Harvesting firewood has a pruning effect on forests, which allows new growth to flourish
• The wood you burn likely comes from your local area--it is not imported as is the case with oil.

• Firewood can be dirty, moldy and riddled with insects--burning remotely keeps the mess out of your home, up to 500 feet away.
• Prevent smoke, ashes, odors, and an eventual buildup of soot on walls and ceilings that is caused by burning wood indoors.
• Alleviate respiratory and allergy problems caused by exposure to moldy firewood, smoke and ash.

• Remove the fire hazard from the home or building being heated -- all burning takes place remotely, up to 500 feet away.
• There is no indoor burning, indoor smoke, and no threat of a devastating chimney fire.
• Eliminate negative affects that indoor burning can have on air quality, including dangerous buildup of carbon monoxide.
• All our models have been tested and listed to UL and CSA standards, except the Pallet Burner which is listed by OMNI.
• The Central Boiler outdoor wood furnaces are non-pressurized systems, which means they are safe and cannot explode.

• Eliminate costly chimney cleaning and upkeep.
• Large wood capacity makes the outdoor wood furnace a low-maintenance alternative to continually stoking your fireplace or wood stove.
• Burn larger pieces of wood -- up to 30 inches in diameter and 72 inches in length -- with no splitting, which dramatically reduces time spent preparing the wood.
• Use soft or hard wood that is seasoned or unseasoned, including junk wood like pine and hemlock and scraps like roots, stumps and pallets -- our furnaces operate efficiently with all of these.
• Load wood and remove ash easily through our large firebox door.
• Simple maintenance requires minutes to perform.

• In addition to being readily available and totally renewable, wood is also very inexpensive compared to other fuel sources.
• Many landscapers and tree services will supply you with FREE wood that they need to dispose of. Call us for local contacts!
• By cutting your own wood, or using waste wood, you can entirely eliminate your heating bills.
• The energy savings realized by heating with one of our outdoor wood furnaces can often pay back the purchase price in the first two years.
• Add a domestic water-to-water heat exchanger, in order to provide all of your hot water. Then turn your water heater off and save big on your electric or gas bill.
• Over a ten-year period, you could save $10,000 to $50,000 or more on heating costs.

• Tests show the Classic is the most efficient outdoor wood furnace, with the fewest emissions. See the results in the left-hand column.
• The water baffle traps heat and gasses in the top of the firebox instead of allowing them to escape through the chimney. (proven by stack temps)
• The Ripple Top^® firebox design creates a high-temperature secondary burn area for more complete combustion.
• It provides optimum heat transfer surface in the most intense heat collection area transferring more heat to the water that is pumped to your home.
• Current owners of our furnaces report that they are using up to 25% to 50% less wood compared to traditional heating alternatives or other brands of outdoor furnaces.
• Indoor wood stoves can be less efficient because heated indoor air used for combustion is sent out the chimney, causing cold air to be drawn into the house to replace it.
