PORTAGE & MAIN OUTDOOR WATER FURNACES  DON'T  JUST MEET THE STANDARDS IN THE INDUSTRY

THEY LEAD & SET THE INDUSTRY'S STANDARD

The extra-ordinary quality and superb craftsmanship of this outdoor water furnace is supported by the fact that there are many 10 to 20 year old Portage & Main outdoor furnaces functioning without problems.

Ash pan and the water cooled grates allow the Portage and Main to bring combustion air in under the grates and over the fire just below the vertical baffle to allow for a more complete burn of gases-quick recovery and reduced smoke emissions.    Also because of the water cooled ash grates and the ash pan, the bottom 1/3 of our stove is not full of ash, we are able to radiate heat into the bottom 1/3 of the fire box which is the cold area and best potential for heat transfer.

The one piece roof of the Portage & Main outdoor water furnace is powder-coated  paint for long life.  The roof has no trims to rust and deteriorate.  It will look good in 25 years.  All components of the Portage & Main Outdoor Water Furnace are painted with excellent enduring products.  The multi-pass heat exchange is completed surrounded by the water jacket which increases the efficiency.  The furnace has a high efficiency rating.  The round fire box has all seams double welded (boiler style).  Journeyman Welders will attested to the significance and importance of this.

The fire pot is completely surrounded by water to maximize heat transfer and built in "Johnson Controls"-- digital water temperature controls automatically adjust the damper. W44 cold rolled steel pickled in oil is used for a long lasting low maintenance fire pot  All surfaces are insulated or water cool for safe operation.  Portage & Main even allows you to clean the ash tray safely while the furnace is operating.

Standard Models come with cleaning tool, certified chemical water treatment and standard stainless steel chimney.

BENEFITS OF A PORTAGE & MAIN OUTDOOR WATER FURNACE

• It will give you peace of mind, safety and convenience because:
  •  no fire hazard in your home or building
  • reduces fire insurance premiums
  • no creosote build up that causes chimney fires
  • no fire pot overheating with the continuously circulating water
  • water temperature is automatically controlled
  • all surfaces are insulated or water cooled for safe operation
  • CSA B366.1-M91 approved
  • it is not necessary to split the wood used as fuel
  • it only needs loading once or twice a day
• It has efficient and dependable features:
  •  Portage & Main Outdoor Water Furnace (wood furnace) burns all types of wood.  The Stoker models  burns coal, sawdust, shavings,  wood pellets, bio-fuels, etc efficiently. 
  • Portage & Main Outdoor Water Furnaces use 1/3 to 1/2 less fuel that most conventional stoves of this type. (wood stoves, furnaces, boilers)
  • the built in multi-pass heat exchanger maximizes heat extraction from the flue gases.
  • modulating combustion provides for a complete efficient burn.
  • air injected under the grates and over the fire just below the vertical baffle allows for a more complete burn of gases--quick recovery and reduced smoke emissions.
• It provides societal & environmental benefits:
  •  Portage & Main Outdoor Water Furnaces use a  homegrown renewable fuel helping to keep local money within the community.
  • wood burners do not contribute to global warming and the greenhouse effect as carbon dioxide emissions from either burning or allowing the wood to decompose on forest floors are the same.
  •  use of a Portage & Main Outdoor Water Furnace minimizes the use of expensive fossil fuels such as natural gas and oil, which cause a net increase in carbon-dioxide which is believed to be responsible for the green house effect.
  • they are an efficient use of alternative, sustainable energy.  Burn a tree, plant a tree, ensure sustainable energy for future generations.
