Boilers, Heaters, and Furnaces Manufactured by
Alternate Heating Systems, LLC.

Our boilers/heaters and furnaces are the core component of some of the most efficient heating systems in the world.  Whatever you need to heat - a maintenance shop, farm building, greenhouse, commercial building or residence, AHS has a Coal-Wood Boiler, Wood Gasification Boiler, or Waste Oil Boiler to meet your needs.  Our line of boilers/heaters and furnaces includes the following:

  • Coal Gun™ Automatic Stoker Coal Boilers
  • Wood Gun™ clean-burning gasification Wood Boilers (with the option of oil or electric backup and the option for automatic feeding of wood particles)
  • Waste Oil Heaters/Waste Oil Boilers
  • Multi-Fuel Boilers (any combination of wood, coal, gas, or oil)
  • Custom-built products specifically engineered for specialized industries with burnable waste materials which can be used as a fuel source

The quality of our boilers is second to none, and they may be used in both radiant heat and forced air heating systems.  They may also be used to produce process hot water for commercial applications.  When used in a residential heating system, an added benefit is that our boilers may be set up to generate hot water for drinking and washing resulting in savings on electricity costs for producing hot water.  Our boilers may be set up to work as a furnace in a forced air system by adding a hot-air exchanger.  See our page that explains boiler terminology and other heating equipment terminology to understand the difference between a boiler and a furnace and to understand the meanings of various words used in describing heating equipment.  AHS boilers, waste oil heaters and wood furnaces/boilers are designed to function as a primary heating system but may be installed in tandem with an existing boiler or furnace.  The existing unit then becomes a backup unit.

Try an Alternate Heating Systems Coal, Waste Oil, Multi-Fuel, or wood gasification Wood Boiler and experience the difference!
