FURNACE INTRODUCTION
Congratulations on your purchase of a new WinterGreen Hydronic Wood Furnace. The Winter-
Green Furnace when properly installed and maintained will give you many years of dependable
wood burning service.
To ensure a safe and proper installation of your WinterGreen Hydronic Furnace, you should:
1) Have your furnace installed by a reputable contractor that has experience with the installation of this
type equipment, has knowledge with Solid Fuel Heating Appliances and be familiar with all local fire
and building codes.
2) Read carefully and use the information that is provided in this manual.
How the WinterGreen Hydronic Wood Furnace Works
Firebox Technology:
As wood burns, it begins boiling out moisture at 100˚C/212˚F. The wood starts to change its chemistry at
400-600˚F and begins releasing volatile gases as it breaks down. Those gases contain 50-70% of avail-
able energy from the wood. Most furnace designs allow those gases to escape out of the stack, wasting
energy. Our Wood Furnaces are manufactured with a refractory fire chamber surrounded by three
inches of high temperature insulation and an airtight stainless steel “skin”. The fire box temperature ex-
ceeds 1500˚F and “skin” temperature is less than 100˚F. The water tube pressure vessel removes both
radiant and convective heat. The heat must travel down past the vessel to the exhaust port, heating the
incoming combustion air on the way. The exhaust temperature is below 300˚F. Once the fluid reaches
the set temperature, the draft is closed and the fire is completely extinguished; it does not smolder. Be-
cause the thermal mass in the refractory stays above the flash point the fire always re-ignites when the
furnace calls for heat again.
Combustion Chamber:
These Wood Furnaces have several unique features that enable them to achieve higher efficiency and
cleaner burns than other wood Furnaces. The refractory combustion chamber ensures a very high com-
bustion temperature and a long flame path with enough turbulence to complete the burning of all gases.
Once the wood gases are completely burned, the hot gases enter the heat exchange area.
Heat Exchanger:
The heat exchanger is a down draft system where the exhaust exits the unit below the entrances of the
cold water and the draft air supply. Because of the differential between the incoming cold water tem-
perature and the exhaust temperature, thermal transfer is increased. The heat in the exhaust is trans-
ferred to the water and warms it as it enters the unit, while also decreasing the exhaust temperature. As
the exhaust continues downward, the I coming draft air is also heated after all the available heat has
already been put into the water. The heate draft air increases the combustion temperature in the refrac-
tory chamber without taking heat from the combustion process.
Water Tube Design:
The Furnaces have a water tube design (Pressure Vessel) which absorbs much more heat per square
inch than fire tube furnaces, withstands much more pressure, and also holds much less water so it re-
sponds more quickly. Because of limited water storage, water tube furnaces are much safer than fire
tube furnaces.
