The Dot Lake community is located on the Alaska Highway 50 miles Northwest of Tok and 155 miles Southeast of Fairbanks. In the 1990s the Dot Lake community installed a Garn 3200 boiler to provide supplemental heat to their school, washeteria, and supplemental heat to 10 homes. The system burns slab wood refuse from a sawmill, which is purchased at $35/cd. The system replaces about 50% of the fuel oil used by the community. The boiler uses a heat exchanger and uses a buried heating system to heat various buildings.
