Classic Edge Titanium HDX Outdoor Wood Furnace

Heat Your Entire Home, Domestic Water and More with Less Wood

Introducing the Classic Edge Titanium HDX outdoor wood furnace, the most efficient outdoor wood furnace that is EPA 2020 Step 2 Certified. High efficiency means less wood is needed to heat your entire home, domestic hot water and more. The titanium-enhanced stainless steel firebox is impervious to corrosion and designed to last a lifetime. Thousands of families rely on their Central Boiler furnace to provide warmth, safety and comfort while eliminating their high heating bill and giving them a better quality of life.

The Most Efficient EPA-Certified Stick Wood Burning Appliances

Others might claim to be the best, but there’s a reason Central Boiler is the #1 manufacturer of the best-selling outdoor wood furnaces.  Central Boiler is the largest manufacturer of outdoor furnaces in the world, due largely to its commitment to make peoples’ lives better by providing innovative, economical and safer heating products.


Cruise Control for the Furnace

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 for any kind of firewood, 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:

  • Easy Refire – saves the coal bed for quick, easy restarts
  • Burn Time Monitor – helps to estimate when you need to add wood
  • Clean Reload – Reduces smoke when you open the firebox door to add wood
  • Text Alerts – 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. With features like Easy Refire and the Burn Time Monitor, burn any kind of firewood.

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.

The Classic Edge HDX is EPA-certified clean-burning and is one of 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.

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

Air control is imperative for the cleanest, most efficient burn. When the fire needs a lot of air (such as during startup or when burning higher moisture wood), FireStar instructs the stepper motors to open the air regulating discs precisely to deliver the amount of air needed. Stepper motors use less power than other air control methods and never need adjustment or replacement due to wear.

Easy Access

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.
