  • Easy to clean!  NO BRUSHES NEEDED!

  • 50-80% Less Smoke Than Competitors

  • Separate Ash Door For Easy Clean-Up - No Grates, Augers, or Ash Pans

  • Fewer Welds Make Our Oval Fire Box 40% Stronger Than Traditional Square Fire Box

  • Extra Large Door Allows Easy Loading For All Wood

  • 100% Airtight Insulation

With over 25 years of designing & Manufacturing Wood Burning Furnaces the Johnson Stove translates technology intelligence, and best available quality into the BEST OUTSIDE WOOD BOILER, bar none.  The round design of our fire-box and water jacket were used in boilers over 100 years ago.  This design provides more strength with less welding and uses 1/4" steel throughout the unit. 

      These wood boilers have a large loading door that easily accommodates large blocks of wood.  The fire box is surrounded by a water jacket which is heated by the fire and then is circulated through your home, garage, or shop to provide the same great heat that you want and expect from wood heat. When your water temperatures drop below the temperature you set for them, dual blowers in our outdoor wood stoves kick on to feed the fire until once again the boiler is in action circulating hot water to and from your home.  This is obviously more efficient than stoves which burn wood and then heat escapes.

Circulator Pumps
These are required to keep water moving between the stove and the area you are heating.  The pump you need is determined by the length the water is forced to travel.  Most stoves are placed between 50' and 200' from the area to be heated.

Piping & Insulation:
It is best to install the piping between your stove and home 18"- 24" below ground.  We highly recommend KITEC piping, an aluminum pipe surrounded by plastic on the interior and exterior of the pipe with a very long life expectancy.  You will need both a return and a supply pipe line and these should be insulated and then encased inside PVC pipe.

Heat Exchangers:
Heat exchangers are for use with forced air systems.  When purchasing heat exchangers, you will want to measure the plennum above your furnace and purchase the corresponding fan size that will fit without going below the current furnace BTU rating.  The manifold will remain exposed.
