If you have access to wood, you can have "free" heat right in your backyard.  A safe, efficient outdoor wood furnace that can provide 100% of your heating needs. Central Boiler is the industry leader in the manufacture, sale and distribution of clean burning, EPA-certified outdoor furnaces.  These outdoor hydronic heaters can be used to heat homes (including domestic water), workshops, pools, hot tubs, greenhouses, and more.   It can even heat multiple buildings.

A Central Boiler outdoor furnace, with patented 4th-generation gasification technology, eliminates the problems associated with indoor burning and allows you to get even more benefits from heating with wood.   A Central Boiler outdoor wood furnace can improve the indoor environment in your home or business, while saving money over non-renewable heating sources like, propane, home heating oil or natural gas whose cost increases when you need it most. 
Classic Edge Titanium Series
  • Provides superior firebox corrosion resistance
  • Allows for longer burn time
  • Extends life of the furnace
Titanium Series stainless models offer the same great features and benefits of non-stainless models with the added benefit of a stainless steel firebox.

Bottom line...Wood Heat: Good For You, Good For Our Environment --- An EPA-certified wood heating system is the right choice for the increasing number of people who are concerned about our environment. Unlike systems that rely on fossil fuels, wood is a renewable resource, which, when burned, results in no net carbon dioxide increase and helps reduce your carbon footprint. Carbon dioxide is part of the natural plant-growth cycle and occurs naturally when trees rot on the forest floor. On the other hand, fossil fuels, when burned, release carbon dioxide which otherwise would stay trapped in the earth. The burning of fossil fuels causes a net increase in carbon dioxide, which is believed to be responsible for the heat-trapping greenhouse effect. In addition, harvesting firewood has a pruning effect on forests, which allows new growth to flourish. And the wood you burn most likely comes from your local area -- it's not imported, as is the case with oil.

Outdoor Furnace Best Burn Practices --- Central Boiler, in partnership with our industry association, the Hearth, Patio and Barbeque Association (HPBA), recommends following the Outdoor Furnace Best Burn Practices.
