The Original Wood Doctor Outdoor Furnace.

Wood Doctor Outdoor Wood Furnaces have moved to the next generation.

Wood Doctor also have a shaker grate to prevent moisture being trapped in firebox. Wood Doctors are now certified by both ASME and UL.
Wood Doctors are now certified for burning either wood or coal.

The Original Wood Doctor Outdoor Wood Furnace is now an Indoor wood boiler or Outdoor Wood Boiler. The same boiler is now also certified as Coal Boilers with a shaker grate.

A Wood Doctor Outdoor Boiler is as the name implies - a boiler that usually sits outside. The hot water furnace, looking much like a small utility building, is a well insulated wood-fired or coal fired, water-jacketed stove. The water in the jacket is simply heated and pumped underground through super insulated pipes to the building that needs to be heated. Wood Doctor now also pressurizes the boiler to prevent corrosion. At this point the heat from the water is transferred to either a hot water system or a forced air system. This process is not expensive and adapts easily to all heating systems. The remote furnace concept is very simple, effective, safe and cost-efficient. As a bonus, it also takes care of all your domestic hot water needs; the element in your hot water heater need never kick in. When keeping proper clearances, these Wood Doctor Boilers may also fit inside your shop or woodshed much like any wood stove or boiler.

Benefits of an Outdoor Furnace

Safety. Wood Doctor Boilers have been tested and approved for placement either inside a building or outdoors. Clearances from combustibles should be adhered to, and all local building codes followed as well. If going out through a roof, use an insulated chimney certified for wood, and follow their instructions and all local and federal codes. However, in many installations a Wood Doctor Wood or Coal Boiler is often situated in the yard, away from the house. The usual distance is 3 feet to 150 feet but the boiler can be twice this distance and still do the job. Outdoor furnaces or boilers remove the dangers of wood stove fires in the house. Any fire department that compares the safety of indoor furnaces versus outdoor wood furnaces will have to admit that outdoor furnaces are the winners; this safety feature is often reflected in lower insurance rates.

Convenience. When the Wood Doctor BOILER is located in the yard, it can be situated beside the wood pile or wood shed. This eliminates the mess of sawdust, smoke, ashes, bugs and dirt in the house. Our injection air BOILER cleanly burns any type and quality of wood or coal. The original Wood Doctor has been heating homes with round logs for many years now. Although the Wood Doctor will burn green wood, if you do season the wood you will burn less because when burning wet wood, it takes wood to dry wood. Depending on the size of boiler and the season, most people top up their furnace with wood or coal in the morning and evening in the winter; and once a day in the spring and fall. This can be extended depending on size of unit and demands. As one boiler can heat multiple buildings; there is no need to purchase a heat source for each.

Cost Savings. Homes and commercial buildings, shops, garages, motels, factories, restaurants can all be heated easily with our BOILERS. There is no more need to use oil, gas or electricity to heat domestic water, hot tubs, swimming pools, clothes dryers - our furnaces will do it better and at a fraction of the cost.
