TimberLine Wood Water Stoves are an alternate way to heat a hot tub or spa! This 100% Aluminum Water Stoves produce about 100,000 BTU (30Kw) of heating capacity by only using wood. You can now heat a medium-large hot tub in hours! These are ideal for off grid applications or to supplement pool and spa heating costs.
The TimberLine Volcano Wood Water Stove naturally circulates the water using no electricity. Its design is based on Thermosiphon; the hot water rises to the top of the pool. At the same time cold water is drawn to the heater to replace the rising hot water and gets heated forming a continuous cycle.
