Heat your home with an outdoor wood burning furnace!

Central Boiler traces its roots back to 1984 in a workshop just south of Greenbush, Minnesota. There, a single idea and some welded pieces of metal would grow into a company that is recognized today as North America’s largest manufacturer of outdoor furnaces, and one of the largest manufacturers in northwestern Minnesota. The company’s innovations and patents come from people who take a little more time, pay a little more attention and go a little further to make sure that every Central Boiler product is ready to meet the demands of the real world.
True to their goal of providing the finest outdoor wood furnaces available anywhere, engineers at Central Boiler have developed the FireStar II electronic controller, E-Link Technology and the FireStar XP wi-fi module. These advancements provide a sophisticated method for controlling the outdoor furnace, sharing operational information and for remotely viewing and controlling it. They represent the most technologically-advanced way to heat with wood ever offered by Central Boiler.

​Thousands of these quality heating systems are in use today in a variety of heating applications, in businesses and in homes. Central Boiler outdoor furnaces are available from hundreds of authorized dealers in the United States and Canada. In addition, Central Boiler offers a variety of heating-related products and accessories.

How it works

While a Central Boiler outdoor wood furnace itself is one of the most technologically advanced ways available to heat with wood, how it delivers heat is a pretty simple and neat idea.

Central Boiler outdoor furnaces burn wood to heat water that is circulated through insulated pipes. Water can transfer its heat by direct circulation or by moving through one or more heat exchangers, or both. Of course, your situation is unique, so it’s important you talk to a Central Boiler dealer to make sure you select the right model for your application.

​The Central Boiler outdoor furnace is located outside, typically 30 to 200 feet (but as far as 500 feet) away from your home or building, and works with any existing heating system.
  • A water jacket surrounds the furnace firebox and heat exchanger, and heated water is circulated to your home or building through insulated underground pipes -- an efficient way to move heat over distances.
  • The outdoor furnace is designed to work with any existing heating system. Water-to-air or water-to-water heat exchangers or direct circulation conveys the heat into the structure's forced-air furnace, radiant baseboard or radiant floor heating system. This allows you normal thermostatic temperature control.
  • The outdoor furnace can provide heat for all your domestic hot water by adding a water-to-water heat exchanger. You can turn off your hot water heater and save even more money!
  • The outdoor furnace has the ability to heat multiple buildings, such as a garage, workshop, shed, greenhouse, or barn -- without using other heating sources. It can even be used to heat a swimming pool or hot tub.
