Using Waste Oil to Heat a Greenhouse
During the winter of 1990, Northwoods Nursery (Elk River, ID) purchased a wood-burning system to heat the current greenhouses. This system burned slabs of wood to heat water that was then pumped into the greenhouses. The winter of 1990 was extremely harsh, requiring non-stop operation of the heating system. In order to keep seedlings in the greenhouse from freezing, the burner required stoking every 30 minutes for 24 hours per day, 7 days per week. If the system was allowed to go out, there was no method available to restart the burner, and all water pipes would freeze very quickly.
