If you lose heat to your hot tub in the cold winter months, don’t panic! For a Fully-Foamed hot tub to start to freeze the temperature needs to be below 28 degrees F for at least 36 Hours straight. Even if it does get that cold if your hot tub & pumps are still operating, the water is circulating and will not freeze.
Freeze damage to a hot tub is a costly repair, so to protect your non-heating hot tub from freezing in the winter months, follow these easy instructions put together by George Thomas our service manage, who is one of the brightest in the hot tub industry:
Protect a Hot Tub from Freezing
- DO NOT DRAIN THE SPA! If it has been drained refill it.
- Periodically run the jet pumps to circulate the water. This will add heat generated by pump motors to your water. (If your jets do not operate go to step #3)
- Place submersible pump in center of foot well of your spa (See image below). Plug in the pump and allow to run in the spa without a hose. This will circulate water in spa and transfer heat generated by pump motor to water. NOTE: Pump should be plastic and NOT SMALLER than 1/4 Horse Power!
- Place a small ceramic heater or a 100 watt incandescent light bulb in the equipment area of your hot tub, making sure that the heater or bulb DOES NOT TOUCH any components or plumbing. Re-install front panel to keep heat inside. NOTE: On SUNDANCE SPAS this is to be installed behind Front Right Side Equipment door Not Center Panel.
- KEEP SPA COVER CLOSED AT ALL TIMES TO RETAIN HEAT.
- If these instructions are followed the spa will be in NO DANGER of FREEZING!
