Classic Outdoor Wood Boilers
Constructed of titanium-enhanced stainless steel, the firebox has superior corrosion resistance and excellent heat transfer performance. This allows loading the firebox for longer burn times (in some cases up to 48 hours or more*) and burning some wood that is less than perfectly seasoned.
Central Boiler recommends burning seasoned wood when possible because dry wood burns better and provides more energy for heating your home. You'll burn less wood, saving you more money and time. That is, after all, what you want your outdoor furnace to do. *Actual burn times vary based on wood types, moisture content, heat load and ambient temperature.
Features and Benefits
- More heat from the wood - the RippleTop design maximizes the surface area of the firebox and the HeatLock Baffle traps the heat in the heat collection area.
- Easy to load - the large, insulated steel door is ergonomically designed for easy opening and closing and insulated to lock in the heat.
- Easy to operate - the automatic draft control opens and closes as needed to control the water temperature in the system.
- Durable and long-lasting - steel siding and powder-coating paint provide unequaled fit and finish and withstand the elements of time.
- Dual Fuel Ready option - All Classic models are available as a Dual Fuel Ready model (standard on the CL 7260 and Pallet Burner) that allows the furnace to be fitted with an optional fuel oil, natural gas, or propane burner.
- Vent Cap - design eliminates evaporation.
- High Capacity Water Jacket - is tested multiple times to ensure welding integrity.
- Ripple Top Design - for increased heat transfer area and lower maintenance.
- Large, Insulated Steel Door - ergonomically designed with a large door for easy loading. Door is insulated for maximum efficiency. Door parts are powder-coated for increased paint durability. Central Boiler's Cam Loc® door closure ensures a tight seal each time the door is closed.
- Automatic Draft Control - thermostatically controls the system water temperature.
- Skid Base Framework - makes installation easy with or without cement foundation. Only the CL 7260 and Pallet Burner require a slab.
- Welded Steel Framework - heavy-gauge framework engineered for enhanced strength of side panels and roof.
- Insulated Chimney - the chimney is a Type HT listed, factory-built chimney for wood-burning appliances. Two 4-foot chimney sections are standard.
- Rear Exhaust Outlet - increases efficiency and eliminates leaks and corrosion that competitors experience from chimneys that exit through the roof. Designed for easy inspection. Reduces heat loss by over 50%.
- Water-Filled HeatLock Baffle - creates secondary combustion area and traps heat in the firebox. Will not warp or burn out with extreme heat.
- Urethane Foam Insulation - insulation is sprayed on and forms a 100% airtight seal around the water jacket.
- Rectangular Firebox - engineered with stay pins. Will not collapse like round designs can.
- Ash Pan - 3/8" thick, formed ash pan is durable and easy to clean.
*Fan Draft option available for all models.

In Our Customers' Words
"When we switched to Central Boiler we started saving $500/month on our heating bill." - Maria, Minnesota
Cruise Control for the Furnace
STAY CONNECTED! More than just a controller, the FireStar Combustion Controller features built-in wireless connectivity, giving you the ability to communicate with the furnace without additional equipment or cumbersome ethernet cables.
The FireStar® combustion "cruise" controller takes all the worry and guesswork out of wood heating. It constantly throttles the air to find the optimal burn, meaning you can “load it and forget it.” FireStar constantly monitors how the wood is burning and adds air where and when it’s needed for the cleanest, most efficient combustion. You can even see how it’s operating in real time on your smartphone or set up notifications so you’ll know when it’s time to add wood.
More features you’ll only find with FireStar:
- Reserve Mode - reserves a portion of the previous wood load so you'll never have to relight a fire
- Burning Time Monitor - helps to estimate how much wood is left
- Clean Reload - Can eliminate smoke when you open the firebox door to add wood
- Text Alerts - if you want, be notified when it’s time to add wood

Durability
The titanium-enhanced stainless steel firebox ensures zero corrosion inside the firebox and can last a lifetime.
Value
Use up to 60% less wood compared to other methods of wood heating and deliver more heat to your home. All Central Boiler furnaces are engineered to minimize heat loss, from the construction of the firebox door, panels and pump access area to the airtight, waterproof spray-on urethane foam insulation. The larger firebox allows for longer burn times, saving you even more time.
Classic Edge HDX models are EPA-certified clean-burning and are among the most efficient, best ways available to burn wood.

Engineered to the Highest Standards...Ours
Innovative Design
The Classic Edge’s patented Air Charge Tube directs oxygen into the Fusion Combustor and keeps coals from falling into the Reaction Chamber. Oxygen mixes with the combustion gases and is focused down into the Afterburner. The Air Charge Tube also helps the furnace to relight faster.
CLICK TO VIEW FIREBALL IN ACTION
Performance
Super-heated gases enter the round chamber of the Afterburner and swirl in a turbulent vortex, creating a Fireball and allowing enough time for complete combustion to occur.
Clean and Efficient
Efficient combustion requires precise air. When the fire needs a lot of air (such as during startup), the FireStar Controller instructs the SmartDraft™ system to open the air regulating discs precisely to deliver the exact amount of air needed. The motors in the SmartDraft system are maintenance-free, use less power than other air control methods and never need adjustment or replacement due to wear.
An industry exclusive, the patented vertical Easy View® Heat Exchanger with hinged door provides full access without the use of tools. That makes for quick inspections and easy cleaning from outside the firebox while standing on the ground.
Better Heat Extraction
Turbulators in the heat exchanger cause turbulence of the exhaust gas flow through the heat exchanger. This forces the heated exhaust to better contact the heat exchanger and transfer more of its energy to the surrounding water jacket before exiting out the chimney.

Features and Benefits
Freedom to do more - Tending an indoor wood pellet stove can be labor-intensive and require constant loading and maintenance. With a Maxim outdoor wood pellet furnace, you'll have more time to do the things you want to do because of the large integrated hopper and extended burn times.
Get in your comfort zone - Unlike indoor wood stoves that can only heat one room, the Maxim provides complete comfort. It uses your existing heating system to deliver the heat so you can set the thermostat where you want in different rooms. You can even heat other buildings like a garage.
Easy to operate - the FireStar combustion controller takes the guesswork out of operating (WATCH VIDEO).
Easy to maintain - the firebox design and heat exchanger system make for easy maintenance and cleaning.
Easy to install - installing your Maxim outdoor furnace is easier than you think. Many customers choose to install their own furnace because the installation can easily be completed using the installation manual (WATCH VIDEO).
- Save as much as 75% on current heating costs
- ELECTRIC IGNITION saves fuel - when there is no call for heat the controller stops adding fuel and the fire goes out. When there is a call for heat, the controller automatically relights the fire if needed
- Integrated hopper is easy to load and holds up to 12 bags of wood pellets
- Heat for a week on a single fuel load or longer with an optional hopper
- Heats multiple buildings, pools, hot tubs and water with renewable wood pellets
- Eliminates mess from inside that indoor burning creates
- Can be installed safely outdoors next to the building being heated
