Hot Tub Freeze Safety, Quality Found Here! The Spa Guy offers advice on how to protect your spa from cold weather. Note: We don't recommend that you ever stop or down your spa for any reason. The reason is that stopping the spa causes things like pumps not restarting, heater failure and hose crud build-up after extended periods of non-use. During the winter even if you drain the spa you cannot get all of the water out of pumps, plumbing and manifolds. When the water stays in plastic parts and the freezing process starts the water expands and breaks the plastic. These kinds of repairs can be costly and sometimes render the spa unrepairable or a total loss.
If you must stop your spa or if it stops and you can not get it to heat we recommend adding a small plastic space heater ($15-$20 at Lowes, Home Depot or Walmart) inside the motor compartment on Low Speed & Low Heat. You are not trying to make it hot under the tub you are trying to stop it from being below 32 degrees under the tub. After placing the heater under on low speed and low heat reinstall the access panel to hold the heater inside. This also works if your tub is already frozen to thaw it out. If the compartment is really tight you can use a reflective light under the cabinet and reinstall the cabinet side until the concern can be solved. This light can be purchased at places like Lowes, Home Depot or Walmart. Add a 75-100 Watt bulb and plug it into a 115V wall outlet. With enough insulation in the tub and the side panels back in place this will usually keep the spa safe.
Note: The heater is much more safe than the light because the bulb can burn items under the tub and cause damage. Note:The heaters will quit after a short time if the compartment is really tight and it can't move enough air so check on it after a few hours to be sure it is operating.
Note: This advice is not a guarantee that your spa will not freeze even if you take these actions, especially in extremely low temperatures. Making the tub run will always be the best way to protect your hot tub.
NOTE: IF YOU MAKE A HALF HEARTED EFFORT TO SAVE YOUR TUB IT WILL PROBABLY NOT WORK YOU MIGHT AS WELL STAY INSIDE AND START FIGURING OUT HOW TO PAY FOR THE DAMAGE. PULLING A PANEL OFF OR OPENING THE FRONT DOOR AND PUTTING THE HEATER OUTSIDE THE CABINET JUST BLOWING IN WILL NOT SAVE YOUR TUB!!
