110V 2000W Hot Tub Heater with Digital Thermostat - Temperature Control for 400 Gallon Spas, Inflatable Bathtubs & Above Ground Pools - Perfect for Relaxation, Hydrotherapy & Backyard Leisure

【Intelligent Temperature Control】Easily set and maintain water temperature between 0-45°C (32ºF~113ºF) with the user-friendly temperature adjustment knob. The thermostat automatically turns on or off based on your set temperature. If the temperature exceeds 60ºC/139ºF, the reset button pops up and cuts off power, requiring manual reset to resume operation.

【Requires Adequate Water Flow】The heater must be used with a circulation pump of at least 0.5HP to ensure sufficient water flow for activation and efficient heating. The built-in flow switch ensures the heater only operates when the pump is running, enhancing safety and reliability.

【What You Get】Includes a 110-120V/50-60Hz, 2000W hot tub thermostat and two 1.5-inch PVC pipe connectors (pipe not included). Use a 1.5-inch PVC pipe for proper connection, ensuring consistent water flow and preventing insufficient flow issues from smaller pipes.

【Installation and Usage Tips】Install the hot tub heater horizontally and make sure the water flow direction matches the arrow on the unit. To speed up the heating process, fill the tub with hot water and use an insulation cover to retain heat, ensuring faster and more energy-efficient operation. Suitable for tubs and spas up to 400 gallons.
