How Do I Prepare My Heat Pump Pool Heater for a Hurricane?
With hurricane season upon us, we have received many questions from customers about protecting their heat pump from the storm. Our systems do not require specific preparation for such weather systems. However, there are steps that can help protect your pool equipment, including your heater, in case of a storm. We will go over some pool preparation steps in this article.
Pool Preparation Before The Storm
- Increase your chlorine level to 10 ppm, the extra chlorine will protect the water. Your filtration and sanitization system will likely be turned off for an extended period of time. This will be dependent on power availability.
- Turn off the electrical power to ALL pool equipment at the circuit breaker.
- To prevent water damage to your pump motor, cover it in plastic bag or any waterproof material you 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 minimize debris and damage to your pool and equipment.
Pool Preparation After The Storm
After receiving clearance to return to your home, or the storm has passed, manually clear out any large debris. Follow these next steps to ensure the area is safe.
First, check for any downed power lines and ensure all electrical equipment and lines are clear, dry, and safe. Before turning on the power to the equipment, uncover the pump motor. The following items in and around your heater should be thoroughly inspected before starting up:
- Inspect the fan grille and fan assembly to ensure debris has not entered the heater. Remove branches, twigs, sticks, and leaves caught in the fan grille assembly. If there is damage to the fan grille assembly, do not restore power to the heat pump. Wait to turn on your heat pump 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. Do not restore power to your pool system if there is any indication of high-water levels. Wait until a qualified technician inspects it to determine if damage to electrical components has occurred.
- If you notice any error codes on your pool heater or other pool equipment, refer to your products operation manual. This will help determine what to check for before calling technical support. If you have any doubts regarding the electrical system, call a pool professional. They can confirm that it is safe to re-start your system.
Once your system is back up and running, it is time to turn your attention to the water chemistry in your pool water, due to all of the rainwater, you might need 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 on some plaster surfaces and vinyl liners.
When the SI (Saturation Index) is too high or low it can also cause damage to the 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 + TH + CF + AF + SC + Saturation Index
Once you have determined your balance levels, take 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:
|Chemical||Ideal Range||Ideal Test Schedule||Effect of Low /High Levels||Corrective Actions|
|Free Chlorine||1 to 3 ppm||Weekly||Low free chlorine: Not enough residual chlorine to safely sanitize pool water. High free chlorine: corrosive to metallic fixtures in pool water. Can bleach swimwear and hair.||Low free chlorine: Check for combined chlorine level and shock as necessary. Increase purifier output to maintain a 1 -3 ppm residual reading. High free chlorine:Decrease purifier output. Let chlorine dissipate normally until 1-3 ppm is achieved. In extreme cases, pool water can be diluted with fresh water or a chlorine neutralizer added. (Diluting will reduce salt and CYA . Check and adjust as needed.)|
|pH||7.2 to 7.8 ppm||Weekly||Low pH: (acidic) Equipment corrosion, eye/skin irritation, plaster etching, rapid chlorine consumption. High pH: (basic) Scale formation, cloudy water, eye/skin irritation, poor chlorine effectiveness||Low pH: Add sodium carbonate or soda ash High pH: Add muriatic acid or sodium bisulfate|
|Total Alkalinity||80 to 100 ppm||Monthly||Low TA: Eye irritation, pH "bounce" stained/etched plaster and metal corrosion. High TA: Constant acid demand, difficulty in maintaining pH, and contrinutes to scale formation or cloudy water conditions||Low TA: Add sodium Bicarbonate. High TA: Add muriatic acid often, a little at a time (may take a week or more to lower the TA)|
|Salt||3000 to 3500 ppm||Monthly||Low Salt: Below 2,500 ppm causes premature cell failure and reduces chlorine production High Salt: Above 6,00 ppm can cause corrosion of metallic fixtures and will taste salty. Note: DIG-220 can safely operate with salt levels up to 35,000||Low Salt: Add salt according to digital display on Pool Pilot® unit or salt chart. High Salt: If undesirably high, partially drain and refill the pool with fresh water. (Diluting will reduce CYA. Check and adjust as needed.)|
|Calcium Hardness||200 to 400 ppm||Monthly||Low CH: Etching of plaster, equipment corrosion |
High CH: Scale formation, cloudy water. Rapid buildup of scale may exceed the system's self-cleaning capability and require manual cleaning of the SuperCell
|Low CH: Add calcium chloride flakes. High CH: Partially drain and refill pool with fresh water to dilute. (Diluting will reduce salt and CYA. Check and adjust as needed) Please note - in some areas there may be higher than recommended calcium levels in the tap water. If this level is seen, call the factory for advice on this condition.|
|Cyanuric Acid (CYA) -Stabilizer -||60 to 80 ppm|
30 to 50 ppm
|Monthly||Low CYA: destruction of clorine by the UV rays from the sun |
High CYA: Requires more clorine to maintain proper sanitizer levels. Note: CYA not needed for indoor or bromine pool. CYA can be reduced to 30 - 50 ppm for DIG-220 in colder climate regions.
|Low CYA: Add cyanuric acid (1lb/5000 gallons increases CYA 25 ppm)
High CYA: Partially drain and refill pool with fresh water to dilute. (Diluting will reduce salt. Check and adjust as needed)

Really, Great article
Preparing a pool heater is not an easy job specially in tropical storm so we should care more while preparing pool heater.
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.

Thank you Linda, appreciate your comment!
Thank you Micky!
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
Thank you Tom!
