How Do I Prepare My Pool Heater for a Hurricane or Tropical Storm?

With hurricane season upon us, we have received many questions from customers who are inquiring about protecting their heat pump pool heater in case of a hurricane. Our systems do not require specific preparation for such weather systems. However, there are certain steps that can be taken to help protect your pool equipment, including your heater, should your area be subject to a hurricane or tropical storm. We will go over some of those in this article.


  • Turn off the electrical power to ALL pool equipment at the circuit breaker.
  • Increase your chlorine level to 10 ppm as you are going to need the extra chlorine to protect the water. Your filtration and sanitation system may be turned off for an extended period of time, depending on power availability.
  • To prevent water damage to your pump motor, cover the motor in plastic bag or any waterproof material you may have available. Also check that it is properly secured.
  • A pool can float out of the ground when the ground around it becomes over-saturated. To prevent this from happening, DO NOT drain any water from your pool. The weight of the water in the pool will help hold it in place.
  • Prune dying or weak branches around your pool equipment to eliminate/minimize debris and damage to your pool equipment and the pool’s finish.

After you have been given clearance to return to your home, or the storm has passed, you should manually clear out as much large debris as possible.

Before turning on the power to the equipment, uncover the pump motor make sure to check for any downed power lines, make sure all electrical equipment and lines are clear, dry and safe the following items in and around your heater should be thoroughly inspected before start up:

  • Inspect the fan grille and fan assembly to insure debris has not entered into the heater. Branches, twigs, sticks, and leaves caught up in the fan grille assembly should be removed. Should you note damage to the fan grille assembly do not restore power to the heat pump until after an inspection by a qualified technician and repairs have been made.
  • Inspect all plumbing and electrical connections for physical damage.
  • Inspect for evidence of high water levels that have since receded. Should any indications of high water levels be noted, power to your entire swimming pool system should not be restored until after an inspection by a qualified technician to determine if damage to electrical components has occurred.

If during your examination or after you power your system, you notice any error codes in your heat pump pool heater or other swimming pool equipment please refer to your products operation manual for information on what to check for before calling for technical support. If you have any doubts regarding the electrical system, you should consider calling a pool professional to make sure that it is safe to re-start your system.

Water Chemistry:

Once your system is back up and running, it is time to turn your attention to the water chemistry in your pool water, because of all of the rain water you might have to re-balance the chemicals.

Utilizing the chart below, you will be able to determine your pool water balance, water is properly balanced if the SI (Saturation Index) is 0 ± 0.3., If SI is greater than 0.3, scaling and staining will occur. If SI is less than -0.3, then the water could be corrosive to metallic fixtures and aggressive in some plaster surfaces and vinyl liners.

When the SI (Saturation Index) is too high or low it can also cause damage to the cell, pool finish or your swimming pool equipment. The basic rule is, high calcium concentration, total dissolved solids, pH, and alkalinity all promise a greater tendency for scale. Scaling potential also increases with higher temperatures.

(PH+TF+CF+AF-SC= Saturation Index)

Once you have determined your balance levels, the proper corrective actions should be taken to rectify, if necessary. The following chart provides you with the recommended chemistry ranges as well as corrective actions for your reference:

Your family’s safety should always be your number one priority. Planning before a big storm or hurricane, and a thorough visual and manual examination after, combined with balanced water in your pool water will ensure their protection and well-being.

  1. We're lucky we don't get too many hurricanes in the UK – on the other hand though we do have to deal with rain most of the summer. Good article for those who need to prepare. Thanks

  2. The most common harm done to a pool amid a hurricane is with the filter system- -particularly with pumps that get to be submerged in water.In the event that your filter system has any possibility of being 'under water',it's best just to take your pump off of the system and put it away.
