ABSTRACT:
An immersible water heater for burning solid fuel to heat water contained within hot tubs, tanks, and the like. The heater includes a vertically oriented combined air-fuel intake tube by which the fuel is gravity fed through an unobstructed opening at its lowermost end into a laterally placed combustion chamber. The combustion chamber terminates at its upper end into a chimney having a top opening above the top opening of the air-fuel intake tube to provide an air draft which cools fuel within the intake tube while, at the same time, providing oxygen for combustion within the combustion chamber. Brackets engaging the lip and sides of the tank or tub support the heater in spaced relationship to the sides and bottom of the container to prevent heat damage.
