Wood Heat That’s Convenient

There is no easier way to heat with wood. Watch it operate in real time on your smartphone. Set up notifications so you know when to add wood. It’s that easy.

Imagine No More…These Are The Facts

Outdoor wood furnaces are what WoodMaster does, and we do them best. Here are just some of the reasons why WoodMaster products have been a leader in the industry since 1989.

We Have What You Need
We offer our furnaces in many sizes, so you’re sure to find one perfect for your heating needs. We also offer a full line of parts and accessories, and the best dealers to ensure your project goes smoothly.

Cord wood or Wood Pellets?
We’ve got you covered. WoodMaster offers a variety of cord wood models for both residential and commercial use, and also the Maxim wood pellet furnace.

Worry Free Times Ahead
Using a WoodMaster outdoor furnace means no longer having to worry about the rising and fluctuating prices of fossil fuels and electric heat.

Say Farewell to “Cold” Heat
Wood heat is the coziest type of heat. Happy and warm WoodMaster customer, Scott, says: Nothing beats the heat from wood. And we couldn’t agree more.

We’re Number One
In efficiency, among another things. CleanFire models are in the top 5 for efficiency of all stick-cord wood heating appliances certified for sale for residential heating in the USA. The CleanFire 900 is on top of the podium among stick-wood burning appliances with a maximum output greater than 300,000 Btu/hr.

Less Wood = Less Work
Our CleanFire is so efficient you’ll use way less wood. 60% less wood compared to other methods of wood heating–giving you more warmth for less effort. That’s a win-win in our book!

Watch Your CleanFire Operate…From Anywhere
Whether you’re on a trip, at work, or just too busy to go outside to check on your furnace…you’re still connected. Keeping an eye on your CleanFire furnace is easy with FireStar – the industry exclusive remote monitoring system.

Convenience Comes Standard
Our CleanFire and Maxim models are equipped with the FireStar Combustion Controller. The Firestar constantly monitors how the wood is burning and adds air where and when it’s needed for the cleanest, most efficient combustion.

No Longer Get Smoked Out
Clean Reload is an optional feature of the FireStar controller that can be used to “tell the furnace to idle for awhile.” This helps reduce the amount of heat and smoke coming from the firebox when reloading with wood or performing maintenance.

Top Performance, Complete Combustion
Super-heated gases enter the round chamber of the Afterburner and swirl in a turbulent vortex, creating a Fireball. This unique effect allows more time for complete combustion to occur.

Maximum Use of Heat
Turbulators in the CleanFire heat exchanger force the heated exhaust to “bounce around” and better contact the heat exchanger. This action transfers more of the heat energy into the surrounding water jacket before exiting out the chimney.

Built to Last a Lifetime
The CleanFire’s titanium-enhanced stainless steel firebox is impervious to corrosion from high moisture wood, creosote or condensation.

Quick, Easy Maintenance
The patented Easy View Heat Exchanger with hinged door provides full access to the CleanFire without the use of tools. Simply open the door for a quick inspection and easily clean from outside the firebox while keeping your feet planted firmly on the ground.
