Description
How long does it take to heat a pool? We recommend continuous operation for at least 16–24 hours, especially for first use. For ideal performance, use a properly sized pump and a pool cover during heating to maximize heat retention. How do i maximum heating efficiency? Use a pump with flow rate ≥1188 GPH. Over‑high flow reduces heat exchange; Over‑low flow reduces heating output. A pool cover effectively reduces heat loss for faster heating and steady temperature. What benefits does the inverter technology provide? It automatically switches to low‑power operation once reaching target temperature, avoiding frequent on/off and temperature fluctuations. It delivers stable, quiet, efficient performance with COP up to 12 for maximum energy saving. How to avoid tripping? What is the rated current of the product (in amps)? Has a rated current of 15.5A.It comes with 20A GFCI plug Make Sure Your Breaker is ≥25A Prepair 15A to 20A adapter if you have 15A Outlet. Can it used in saltwater? Is it waterproof?

This heater is awesome. I installed myself, super easy setup (you do need a dedicated 30amp breaker). The app has worked well, it does sometimes become disconnected and you have to trip the breaker for it to connect again. I have a small 11k gallon play pool and it was able to stay heated in the winter nicely when I use a pool cover. It runs very quiet and doesn’t take up a bunch of room. I did get a bigger unit to be able to heat better which also helps a lot during winter. It can heat about 4-6 degrees per day in the winter covered. Once fully heated I just let it run as the biggest expense is the initial heating from cold. My total electric bill is only $3-4 per day so it’s very cheap to run. Would buy again.

LOVE THIS HEATER!!! Wish I got it sooner. Its a great deal! I purchased the one recommend for my pool size. After one day it was warm enough to swim!! Ive been searching for many years and this heater truly works!!! Its so easy to set up! We did end up needing an extra hose. Thats for my particular pool. Its unsure if you will need to. Walmart has pool filter hoses if you do. Water temp starting was 78 degrees fahrenheit and after one day its 82 degrees Fahrenheit!!! Its the perfect size and fit for around your pool. Its 70lbs and very durable and sturdy. This is the best heater for your pool and budget! My video wouldn't load.

I purchased the HEX100 AquaStrong heat pump for my 16’ x 32’ inground pool. I live in Middle Tennessee and plan to open the pool a couple months earlier (Mid April to mid-May) and keep it open until the end of October (before leaves begin to fall). My pool is about 20,000 gallons. The HEX100 unit is rated for up to 26,000 gallons. I received the unit a few days after ordering. The install was fairly straight forward. I installed a 40 AMP breaker at my main panel and a 50 AMP GFCI between the unit and the main panel. All wiring is 8-gauge copper. I placed the unit on 4 – 4” blocks that sit on a concrete pad so the unit is 4” above the ground level which allows for good drainage. The rear of the unit is only 16” from a wood picket fence. I believe there was adequate ventilation but I installed two grills on the fence to make sure there was good ventilation. I used Schedule 40 PVC pipe to connect to the pool filter outlet pipe utilizing the PVC fittings provided with the unit and created a bypass if I need to bypass the heat pump. The unit started up with no issues. The pool temperature was 66 degrees F when I started the unit the evening of April 20. The outside temperature was 60 degrees and the low temperature got down to 46 degrees that night. At startup the inlet temp was 66 degrees and the outlet temp was 68 degrees at the standard mode setting. Tuesday evening April 21 the outside temperature was 77 degrees, inlet temp was 75 degrees and the outlet temp was 80 degrees. Wednesday evening the outside temp was 78 degrees, inlet temp was 82 degrees and outlet temp was 86 degrees. Thursday April 23, I was expecting my grandkids to come swim so I changed the Mode setting to boost mode around noon. The outside temp was 78 degrees, the inlet temp was 85 degrees and the outlet temp was 91 degrees. I had a target temp for the pool set at 90 degrees. By Thursday afternoon it had reached the 90-degree target temp. So overall it took from Monday evening to Thursday afternoon to increase the pool temp 34 degrees (66 to 90) which is not bad. It probably would have been faster if I had started in boost mode. My electric utility company provides me with usage info so I calculated the initial cost to bring the pool temp up 34 degrees within 3 days and it was approximately $70. Going forward the cost to keep it at this temp should not be as much. I am able to control the unit from my iPhone with the app provided. It is very easy to setup and navigate, allows for schedules to control the unit if you want. I am very satisfied with this unit. I know it will accomplish my goal to bring the initial temp to 90 degrees at the beginning of the season (3rd week in April) and keep it there. For middle Tennessee, once the summer months are here (June – August) I don’t expect the unit to run very much as the outside temp along with the full sun will keep the water temp at 90 degrees. The AquaStrong customer service response has been excellent via email. They get back to me within 24 hours with any questions I have. I would buy this unit again and can recommend it to potential customers looking for a way to heat their pool.

I purchased this unit a few months ago, but it took some time to find a technician willing to install it. Several pool service companies declined the job because they were unfamiliar with the brand. Once I found someone willing to take it on, the installation itself proved to be quite straightforward. The instructions provided by the manufacturer are clear and easy to follow. However, despite that, the initial installation was not completed correctly. When the system did not perform as expected, I contacted the manufacturer. Their customer service was exceptional—responsive, cooperative, and genuinely committed to resolving the issue. They even assured me that, despite the time that had passed since purchase, they would be willing to issue a refund if the problem could not be resolved. They requested a video showing the installation and system operation. After reviewing the footage, they quickly identified an installation error. My pool technician returned, corrected the mistake, and the system has worked perfectly ever since. We are now enjoying a comfortably heated pool. The unit operates very quietly and has performed exceptionally well. For our 18,000-gallon pool, it raises the water temperature by approximately 1°F per hour, which has exceeded our expectations.

I installed my HEX075 heat pump in July of 2025. Over the two days prior to installation, for about an hour each day, my 14-year-old son and I reviewed the instructions that came with the heat pump. The instructions were clear and concise, and easy to follow. I am using this heat pump unit in tandem with an 18"/1.5 HP Aquastrong Sand Filter. This sand filter/pump paired perfectly with the HEX075 heat pump, maximizing heat flow by way of a near perfectly matched flow rate. The family is still telling everyone that will listen about how great it is to not have to wait for a string of hot days in Western PA to go swimming; just leave the heat pump fired up and enjoy 88 degree F water all summer long - morning, noon, and night. And as if that wasn't good enough, the filter/pump and heat pump both have internal timers, such that this setup becomes 'set and forget' to a very large degree, aside from the occasional backwashing and rinsing of the filter media. Beautiful! Additionally, and probably most importantly, the ease with which I was able to get any questions answered by way of a few emails to Aquastrong (which were ALWAYS promptly and concisely answered) was second to none. Full stop. For example, I was made aware of a design shortcoming with this heat pump that could possibly result in moisture ingress to the touch screen; I was told that an updated touch screen was being finalized, and upon completion, the updated touch screen would be sent to me. Sure enough, after a fair amount of overnight rainfall, I was seeing that the ingress of moisture was affecting the touch screen performance. I sent an email to Aquastrong, noting this fact, along with our prior correspondence regarding the updated component. When I got home from work a few days later, this updated touch screen was waiting for me on my doorstep. After a quick 10 minute fix to remove the old touch screen and replace it with the redesigned one, I was up and running again. Kudos to Aquastrong for hitting that sweet spot in relation to quality of product, coupled with fantastic technical customer service. We ran this unit for about 4 months, before winterizing it for the season , and it performed flawlessly throughout. It's a breath of fresh air to make a fairly substantial purchase like this, and have NO COMPLAINTS. Great work!

We bought an undersized version (Hex035) of this heat pump for our 24’ pool. We just wanted to be able to have a little temperature boost during the swimming season in Wisconsin, as the pool can easily cool down to 70 degrees if we have a cold spell. The pump has worked great! It adds about 5 degrees per day when temps in the 70’s, and maintains the temp over night (no pool cover) and night time temps into the 50’s. The hose adapters are easily exchangeable (once I figured out you simply unscrew them with a pvc wrench). The rest of the unit seems high quality, and the unit was light enough for my wife and I to carry to the back yard. Support is also incredibly helpful via WhatsApp. You may have to wait for a response overnight, but they do get back to you and are very helpful, even offering to send me a replacement unit for a minor temperature sensor issue I was having, in order to have a working unit in time for a planned party we had quickly coming up. It’s great that we could do this for just $1200. And plug into our existing pool pump outlet, though we needed an adapter plug, which cost about $4. We purchased a gas heater in 2000, which cost $4k, and cost $1/degree of heating. This new unit is MUCH more efficient.

This pool heat pump has changed the way our family uses our pool! Even in South Florida, our pool temps would dip below 80 degrees in the winter, and the kids would say it was too cold!! Now we keep the pool a perfect 86 degrees year round. Once it comes to temp, it holds it so efficiently and effectively The app on my phone makes it super easy to make adjustments whenever needed. Surprised by how quiet the unit is for the size. We oversized a bit to ensure maximum efficiency We haven’t hit the dead heat of summer yet, but I suspect it will help lower the temperature of our inground pool just as well as it has been able to warm it up. I would recommend professional install if you don’t posses the skills needed. I was able to install it myself easily with the included instructions and a little bit of basic know how I’ve already recommended this same unit to a neighbor who was jealous of us swimming in January!

Works great! Nice and quiet. We already had a gas heater but wanted to use electricity since we have solar panels. The Tuya app is adequate but I was able to get it working with Home Assistant using the Tuya Heat Pump integration in HACS (just added a pull request for this model). Supports local or cloud connection.
