Maxim Outdoor Corn and Wood Pellet Furnace

Save on heating bills with a Maxim outdoor wood pellet and corn furnace. Use wood pellets, corn or other types of biomass to heat entire buildings, domestic water and more.


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 and corn 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.

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.

  • 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 or corn
  • Eliminates mess from inside that indoor burning creates
  • Can be installed safely outdoors next to the building being heated
