Whole House Comfort System
Add-On Wood/Coal Furnaces

The Woodchuck Add-on furnace line can eliminate the unpleasantries of in-home wood-burning. The Woodchuck is usually placed next to your present Central Heating unit instead of the main living area of your home. This means NO firewood, dirt, or bark to clean up, or hot surfaces to guard from small children. Woodchuck offers the comfort of luxurious, even heat distributed throughout your home. The cost of oil and gas DOES NOT mean you must abandon or replace the central heating system designed for your home. After all, it's the oil and gas consumption we want to reduce, not the system.

How The Nature's Comfort Outdoor Wood Furnace Works!

Simple! The interior workings of the outdoor wood furnace consist of a firebox, and within the firebox is a chimney, a grate with a powered blower that forces air up into the fire for a greater and more efficient burn. Wood is loaded into the firebox the same way as a traditional fireplace.

Surrounding the firebox is at least a 120 gallon water jacket. The wood is burned in the firebox, thereby heating the water in the surrounding water jacket.

A pump at the back of the outdoor boiler sends the heated water on a continuous loop to the house through an insulated PEX line to a heat exchanger on your furnace and the water heater inside your home, then back again for reheating.
