Best Value for Your Money!
Size: 17000 Gallons
Purchased the 58k BTU model for a 24’ x 54” above ground pool. After much research, this unit appeared to have the best performance, warranty, and value when compared to similar class competitive products. The unit was well packaged and appears very robust and well made with quality materials. It installed easily in a weekend with parts available from your local hardware. It is extremely quiet and can’t be heard over my 1.5HP Hayward filter system. It did leak at first start up. I found the factory installed water adapters were loose. They are designed to seal by o-ring, but I added some thread sealant anyway and torqued them down. No more leaks. Their customer support team is extremely responsive, which helped solidify I made the right decision. So far, the heating performance is as expected. There are many factors that affect how quickly the pool will heat. You also need to be grounded with the right expectation. If you want to heat your pool temp up by 20+ degrees in a cold climate within 4 hours, you’re wasting your money. Go get a gas unit and watch the dollars flows. If you want to be realistic in how much you can heat and how quickly, this is the perfect unit for you. The one thing that could be improved is the app. I would love to see them develop their own app to get similar function as what you get on the unit interface. ... show more

Great heater and even better customer service!
Size: 5000 Gallons
We have a smaller 3500 gallon above ground pool that is shaded, and this heater has done a great job getting our pool to temp. It also indicates when the flow of water isn’t strong enough which clues me in to when I need to clean the filter. About a year in, it stopped working suddenly (would not power on). The customer service for the warranty was fantastic. Prompt and responsive, clear on instructions, and helpful with troubleshooting and getting the problem solved as quickly as possible (the plug from the heater had broken and needed to be replaced). It’s back up and running and I’m really happy with the service! ... show more

Great Quality
Size: 12000 Gallons
I ordered the 40,000 btu heater on a Tuesday at 6:00 pm. It was in my driveway the next day at 1:00 pm! (It shipped from a location 90 miles away, but still impressive!) It was packaged nicely in two heavy cardboard boxes with foam pads on bottom and top. I saw zero shipping damage. The shipper did leave it lying on the end - even though the box is cleary marked with a "THIS SIDE UP". This could be important since it has an oil-filled compressor. Just be sure to let it sit correctly oriented for at least an hour before powering it on. There are two handles built into the cabinet for easy moving, but it's pretty heavy. Not a big factor in my choice, but i did like the grey color better than white or black. The fit and finish on the cabinet is very good. It is a very nice-looking unit. It came with two 1.5" pvc adapters, so it was easy to plumb to my existing plumbing. I was also pleased to find that the power cable was already installed and ready to connect. It even had terminals attached but I cut it off to the length I needed. This made wiring to my existing breaker a 5-minute job. There is a control panel (thermostat) mounted to the side with a protective hinged cover. The control panel is backlit but the controls are a little cheap feeling and the icons are tiny. I would give it a 1/2-star knock for this, but overall I'm good with 5-stars. The control panel can be used to change the set point, set the clock, and change modes. You can also program a schedule, but i have yet to do that from the control panel. There also seems to be a troubleshooting menu, but I haven't looked into that. My favorite way to interface with this heater is with the wifi app. It's one of the easiest wifi appliance apps I've set up. You can control most features with the app from anywhere. It also has a query screen where you can see water temps, if the compressor is running, if there is water flow through the unit, etc. This could be a valuable troubleshooting tool. You can set up a schedule from the app, but it's not as full-featured in this department as I'd like. I tried the heater on the first night. The outside temps fell down to about 62F, and the water was 91F the next morning. We kept the solar blanket on overnight as well. By the 10:00 am the water was 93F. The outside temp got up to about 86F at peak. I then tried the cooling and it switched back quickly and started cooling it down. Our pool is in-ground 12,000 gallon, so it will take hours for a heater like this to make significant changes, but it seems to be doing what a 40,000 btu heat pump should do. This heat pump is VERY QUIET! The little noise it makes is a pleasant hum... .mostly just the fan blowing is what you hear. When in heat mode, very cool air is being exhausted from the unit, which could be good or bad depending on its location (vise versa when in cool mode). This isn't a ding, just a heads-up. I solidly recommend this brand. If I have any issues. I will update. ... show more

Not looking promising on day 1
Size: 5000 Gallons
Let me start off by saying I am replacing a 9kw electric heater with this heat pump. While it is 220v and pulls 40amps when heating, I do get a significantly higher temperature rise and I am not required to run my pump or heater 24/7 as I can raise the pools temperature by 20 degrees in just a few hours. I installed this heat pump on an 8’ stock tank. This tank is roughly 600gallons (way below rated water capacity for this heat pump). Initially I was unable to get any temperature rise out of the heat pump so I added valves to the inlet and outlet on the heater to throttle water flow and even then I am only able to get a maximum of a 3 degree rise. The data plate states RLA as 7 amps and some change but I am reading 9-10amps. Add this with the 4-6amps of my variable speed pump running 24/7 and I am having a hard time justifying that this is a more comfortable or efficient option. ... show more

Fantastic to extend the pool season. Heater is a solid piece, arrived within a week. And looks simple to set up.

Extending midwest pool season
Size: 8000 Gallons
This heater has been great for extending our pool season. Had an issue with condenser still running after water reached temp and the seller QUICKLY sent out the replacement part which was super east to replace. I did have to install a valve o reduce pump flow which I knew ahead of purchase. For reference, ours is the 30k btu on an 18’ x 48” round pool. We average 1 degree per hour. Did not notice and change to electricity bill. Very pleased with this purchase and the seller! ... show more

So far so good
Size: 5000 Gallons
I purchased a different brand heat pump for my hottub and I had to return it because of how loud it was (its fan sounded like one of those bounce house blowers, it was obnoxious)...I was pleasantly surprised that this unit was no louder than a small window a/c unit, perhaps even quieter. The fan is basically silent, the only thing you can hear is the compressor but it seems they install a sound blanket around the compressor making the unit run as quiet as possible. The heat it outputs is beyond adequate for my ~200 gallon hottub, when not in use the unit only needs to run for 25-40 minutes every 6-7 hours! When in use, it has more than enough power to keep up even with the lid removed on the coldest of nights (for my location, high 30s-low 40s)...this is exactly what I wanted becuase the original electric heater on my hottub was very weak and the water would become luke warm quickly with the jets on cover off on those cold nights and I would need to get out. The defrost mode seems to work well, only pausing heating for a minute or two to thaw out and then going right back to heating. No doubt this unit is going to save on electricity with how well it heats and how little it needs to run to keep temp on my hottub. I have only two minor gripes. 1. The app control is hit or miss, doesnt connect unless im near the unit despite being paired to my router. But again, this is minor because I dont expect the need to monitor or control my hottub unless im there in person. 2. The default temperature differential was set at 4 degrees from factory. The manual provided gives zero info on how this can be changed. I.E. if its set to 104, it will let the water drop all the way to 100 before restarting to heat back up to 104. Reaching out to the seller, they were able walk me through a secret menu on the display to alter this setting. This secret menu seems to have a long list of different settings that can be adjusted. I asked the seller if they could provide data on what all these other settings do, and they seemed to not want to tell me... asking "what else do you need to adjust". This unit isnt cheap and I paid for and OWN IT. What I want is a list of what all the settings are on something that is now mine, it doesnt matter if I need to change anything else right now. All of these settings should have been outlined in the manual, i shouldnt have to pull teeth to find out what they are. The controller inside the unit looks like its made by some other company, so I might see if I can find more info on it that way. Deducting a star for this headache. Overall a great experience. ... show more

Easy and Effective
Size: 17000 Gallons
Purchased this 58,000 BTU unit (after returning a unit of another Brand) for a 12,000-gal pool. Included plumbing adapters are standard pvc sizes so installation was relatively simple. The control panel is easy to use and hook up to Wi-Fi. North Florida saltwater pool application, installed late February, outside temps starting to climb into the 70's with lows in the 50's. Pool temp went from 68 degrees to 78 degrees in the first overnight 24 hrs and reached 82 by the end of the 2nd day, only daytime heating since. Nice looking unit, sturdy envelope, not too heavy so I was able to position it without assistance. Consistent delta T of 3 degrees when engaged. For a heating unit, I will highly recommend. Waiting on Summer to see how the cooling functions. So Summer has come and almost gone now. The Chiller function worked well here. Unit kept my pool in the low to mid 80's effortlessly for the better part of the season. The pool reached 88 only on the hottest days when temps reached the high 90's for several days in a row and the sun was relentless. Didn't have to run the pump at night or try to shield the pool with my umbrellas. Still very happy with the purchase. ... show more
