Next Generation of Outdoor Wood Furnace, the Pristine Gasification Series

Up to 60% Less Wood consumption. Using Negative Pressure, our line of Down Draft Gasification furnaces surpasses the strictest laws and are EPA Phase 2 certified.

It’s time to rethink how your home is being heated. This series of outdoor wood furnaces is constructed from 409 Titanium Enhanced Stainless Steel and is one of the most economical and energy efficient models on the market, burning up to 60% less wood, while achieving a 99% combustion efficiency, making it virtually smokeless.

Enjoy the convenience of using readily available, renewable resources, while eliminating the indoor mess by keeping it outside.

Heat Exchanger Cleaners

A Heat Transfer & Cleaning System Unlike any Other

 

Our outdoor wood furnace Heat Exchanger Cleaners are stainless steel twisted tape turbulators that maximize thermal efficiency and heat transfer. Easily accessible from the front of the stove, simply push and pull the Heat Exchanger Cleaner handle to remove any build-up of fly ash from the Heat Exchanger tubes.

Constructed out of 409 Stainless Steel, these Heat Exchanger Cleaners are a snug fit, spiral design, that slow down the flow of hot air moving through heat exchanger. Slower flow means better contact with exchanger walls increasing heat transfer efficiencies.

Flush Mounted Secondary Combustion Chamber Door

 

Utilising the same Roller Bearing Door & Latch system as the Firebox Door, the Secondary Combustion Chamber Door has a large opening making it easy for regular maintenance of the outdoor wood furnace.

afety is the primary goal of the Secondary Combustion Chamber Door design, which is why it is manufactured with three layers of insulation. For added insulation, and safety, a Heat Shield is inserted directly behind the door.

Primary Combustion Air Panel

A Better Air Panel Design

 

Constructed from the same 409 Stainless Steel as the rest of the outdoor wood furnace, the Air Panels of the Pristine Series enhance the air distribution while mitigating wear and tear on the firebox and structure.

The Air Panel Hook is designed to allow each section to expand and contract independently, preventing them from cracking the poured refractory Gasification Manifold or piercing the Water Jacket.

Additionally the Air Panels are designed to be replaceable as they age, drastically increasing the lifespan of the outdoor wood furnace.

gasification manifold

The most advanced Gasification process in any outdoor wood furnace

 

The Gasification Manifold is a uniquely designed, high temperature poured refractory unit, that injects preheated air directly at the combustion zone.

This process drastically increases the burn efficiency, igniting all gases, causing the flame in the second combustion chamber to reach as high as 2,300°F

Outdoor Wood Furnace Negative Pressure Gasification Combustion

 

For the Pristine Gasification Series outdoor wood furnaces to achieve a 99% combustion efficiency we had to take a new approach to air flow.

Instead of “pushing” the air from the top, we decided to “pull” the air from the bottom, creating a Negative Pressure Gasification System.

When the outdoor wood furnace is completely sealed, the air is “pulled” downward, forcing all gasses from the Firebox through the ash bed into the Secondary Combustion Chamber.

This makes the system virtually smokeless, with lower exhaust temperatures at the chimney, and allows wood placement to be more forgiving

the Gasification process explAINED

 

Gasification has been around for decades and is the most efficient way to heat your home. A combination of high temperatures, dry wood, and limited air, create exhaust gases inside the firebox. These exhaust gases are forced downward through the wood fire ash bed into the secondary combustion chamber which burns at temperatures up to 2,300°F with a 99% combustion, this process ignites gasses removing any smoke while the unit is operational.

This heat is then transferred to the heat exchanger tubes which are strategically placed in the water reservoir to transfer heat to the water, assisting in achieving high efficiency and low emissions.

The unburned gases exit the stainless steel flue exhaust at temperatures as low as 300°F. You will notice that our Pristine Gasification Series of outdoor wood furnaces is virtually smokeless, this is due to our Negative Pressure Gasification process. The less smoke you see, the better the efficiency

 

Negative Pressure Gasification

 

  • When the outdoor wood furnace calls for additional heat, the furnace fan is activated.
  • Fresh air is then pulled from the air intake, near the bottom of the furnace, at the rear.
  • The air is then split, and injected, both above the fire and directly at the combustion zone.
  • The furnace fan pulls the air through the entire system, creating a singular, downward / negative air flow.
  • Generated energy then passes from the Secondary Combustion Chamber into the Heat Exchangers.
  • Up to 90% of the generated energy is then transferred to the Water Jacket from the Heat Exchangers.
  • Finally the cooled exhaust exits through the chimney
