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.

Only issue ever had was shower heads on & off switches can be testy. Make sure to use a pump if you are not using a pressurized hose.. Cheryl. New York. Wed Oct 01 2025

The AHS18-D electric tankless water heater delivers reliable on-demand hot water in a compact, space-saving design. Built for residential and light commercial applications, this 18 kW, 240-volt tankless water heater uses advanced iHeat™ Closed Loop Modulation to automatically adjust power usage based on hot water demand, helping improve efficiency while maintaining consistent outlet temperature. Designed with 3/4-inch NPT water connections, a 0.25 GPM minimum activation flow rate, and a durable stainless steel construction, the AHS18-D is ideal for high-demand point-of-use, multi-fixture, or whole-home applications depending on climate, incoming water temperature, and flow requirements. Its digital controls, integrated flow meter, real-time monitoring, and USB diagnostic capability make it a smart, serviceable upgrade from traditional tank-style water heaters. With no storage tank to refill, the AHS18-D provides continuous hot water when properly sized and installed. Its compact wall-mounted design helps save space, while the stainless steel heat exchanger and enclosure help resist corrosion and support long-lasting performance. Official Drakken specs list this model as 18 kW / 75A, requiring two 40A breakers, with 3/4-inch NPT connections, 150 PSI max pressure, and dimensions of 16" H x 13.5" W x 3.5" D
