Thermospas hot tub service expert Mike Tierney gives some tips on how to prepare your hot tub for a winter storm:
Do not drain your hot tub.
Draining your hot tub without properly winterizing it can cause serious damage to the pumps and lines – damage that is not covered by your warranty.
Keep your spa running at the max temperature.
If the power goes out, a covered hot tub at 104 degrees can retain its heat for 2-4 days in cold weather. Keeping your hot tub at its maximum temperature will buy you the time you need to have a technician service your spa before it becomes a more serious issue.
Protect your circuit board
If you are experiencing frequent power disruptions, you may want to turn off your circuit breaker temporarily until the power supply becomes more consistent. Significant power surges could damage the circuit board.
If your hot tub breaks down:
If your hot tub stops functioning before or during the storm for non-storm related reasons, there are steps that you can take to prevent damage until it can be serviced. You will want create as much heat and water movement as possible to prevent your spa from freezing.
The worst thing you could do is drain your spa! If you drain your spa without properly winterizing it, there will still be approximately 20 pounds of water left in the plumbing lines of the spa. This water will freeze much faster when the tub is empty, causing serious damage to your hot tub.
Instead, you can generate heat and water movement with the use of a submersible pump. Since we do not want to drain the spa – do not attach a hose to the pump. Simply place the submersible pump in the foot-well of the spa and let it run consistently, 24/7, until your hot tub can be serviced.
By putting the pump in the foot-well of the spa, it will simulate a waterfall effect, creating water movement while at the same time generating heat. It is vital that the hot tub remains at a warm temperature, so keep the hot tub covered while the pump is running to retain as much heat as possible.
