Heat Syphon New Way To Save Fuel
Cost of a 20 ft. long unit is $49.17, including the motor. A 30 ft. long unit sells for $61.05 and a 40 ft. unit for $65.95. One Stratotherm Heat Syphon will serve an area up to 1500 sq. ft. (2000 sq. ft. in a multiple installation). A unit placed within 18 in. of the ceiling will continuously force warm air to floor level, through the inflatible plastic tubing, at the rate of 120 cfm. At floor level, warm air from the ceiling is exhausted into the strata of dense cold air. It intermixes and rises, forming a continuous air current which circulates from floor to ceiling. "This continuous mixing and stirring is gentle, with no drafts," Rusth points out.
The Heat Syphon requires no thermostat. "A thermostat would limit the operation to a preset temperature level. Heat will rise, regardless of temperature and should be recirculated," Rusth explains.
A similar unit designed for use in the home is called the Thermocycler. Instead of an inflatible plastic tube, it has a rigid plastic tube finished in beige or walnut. A standard 8 ft. unit sells for $39.95.
