Patented Backup Thermal Protection to Help Prevent Your Spa from Freezing in Winter!
The Spa Dragon monitors the water temperature in your hot tub. If the temperature drops for any reason, The Spa Dragon will activate the heater to warm the interior to help prevent damage from the cold.
You could be on the beach in Mexico, and The Spa Dragon will notify you when activated that you need to call a service tech.
No more asking friends/relatives to babysit your hot tub every day while you're away!
