Nature's Comfort GT & NCB Series Wood Burning Boilers
GT-500 & GT-220 Down Draft Boilers
The GT-500 & GT-220 are three stage down draft wood burning boilers utilizing high temperature gasification and a honeycomb catalyst filter in the burn process.
New! Add the SM-H60 solar heating system to most Nature's Comfort Boilers and boost the efficiency to as much as 100% !!
What this means to you:
- Little or no smoke – clean air!
- High efficiency wood burning – Uses less wood to heat your home.
- Less ash and less cleaning.
- Less time spent loading wood.
- Environmentally friendly
How the GT-220 & GT-500 Work
Stage one burn occurs in the main fire box. The gasses from this stage are forced down into the second stage double secondary burn chamber, where the gasification process occurs at temperatures near 2000°F. The exhaust gasses from the gasification process then pass through the stage three ceramic catalyst filter, which burns any remaining particulates.
Throughout the three stage combustion process heat is efficiently transferred into the water jacket, then transferred to your home, shop or other buildings, providing economical environmentally friendly comfort all winter long.
The GT-220 outdoor wood boiler is now available in a non-sheltered model at a significantly reduced price. Call Greg for availability and pricing.
The GT-220 is one of the most efficient low emission outdoor wood burning boilers on the market today! Just remember always burn well seasoned dry wood for highest efficiency - Greg
