Heat your hot tub when you want to use it with the SUPA Heater, a portable propane-powered system that delivers 105,800 BTU/hr of heat output for home and commercial outdoor spas. Use the supplied self-priming pump and two 10-ft hoses to recirculate and heat the water already in your tub, or connect the system to an outdoor water supply to hot-fill your spa. Under standard conditions, SUPA can heat a typical 265-gallon hot tub in approximately 1 hour. Actual heat-up time varies with water volume, starting and target temperatures, weather, fuel supply and setup.
The wheeled frame makes the 47-lb heater easy to move between backyard hot tubs, vacation rentals, glamping sites and campgrounds. Digital temperature control helps you set and monitor the outlet temperature. The system is compatible with hard-shell acrylic, inflatable, foam and wood-fired tubs.
The package includes the SUPA Heater, self-priming pump, cover, shower head, one 10-ft hot hose, one 10-ft cold hose, QCC-1 Type 1 regulator and gas connection kit. The propane tank is sold separately; a minimum 40-lb tank is recommended.
For safe operation, never enter the hot tub while the heater is running because return water can reach 149°F. Keep the tub temperature at or below 104°F and circulate the water for at least 30 seconds before entering. Limit each operating cycle to 90 minutes, followed by a 15-minute cooldown. Use below 2,000 ft elevation, protect the heat exchanger from freezing and follow all supplied assembly and operating instructions.
