Bob’s system uses the wood waste generated by his sawmilling business to heat the kiln, he can dry 6000 BF of lumber in about 100 hours using only the waste from his woodmizer, the system was cheap to build and most of the lumber for it was cut on his sawmill, the basis for the system is a non pressurized boiler.
This boiler consists of a firebox and water jacket, the fire heats the water which is circulated through a very large radiator 36 inches wide by almost 40 feet long
The radiator is made out of heat tube which is easily available at many heating and plumbing suppliers
The hot water is circulated through the radiator with a small pump
As you can see the boiler that powers this system is quite small so Bob intends to replace the boiler with a new one
This boiler will be used to heat Bob’s house his kiln and his hot tub, the capacity is larger than his old one.

The kiln has a set of tracks just like the big kilns do
Tracks and door
The kiln can hold up to 7000 BF of lumber depending on the thickness of the boards
Inside the kiln
The kiln is fed air by 2 furnace blowers mounted to the wall
Several circulating fans keep the air moving
The walls are 8 inches thick made from laminated 2x8 cut on bobs woodmizer
Over all this kiln represents the finest in ingenuity and craftsmanship, cheaply made and smartly designed, the kiln dries wood almost every day including the winter months when it often gets to 30 below.
