  • Excellent Pool Heating & Cooling Unit
Size: 21000 Gallons
I already knew inverter technology is superior to standard single stage heat pumps but I was concerned at the companies claim this pool heater could heat up to 21,000 gallons. I installed myself, actually very simple. Running the a new electric circuit through the attic was challenging at 70 yrs old but I survived. Making the concrete pad was no fun either but I prefer to do things my way. The re-piping of the pool pump to the heater was easy enough but you should draw out what you need and make certain you enough fittings (mainly 90 degree), Tees and valves. The valves are critical because depending on the pump revolutions per minutes (RPMs) you may to reduce the water flow coming out of the heater. Each model has a different gallons per minute (gpm) requirement. The unit comes with an MPa gauge, is a type of pressure gauge that measures pressure in megapascals (MPa) on the back and you want the water pressure to stay in the Green zone. Lower the number on the gauge means high water flow but less heat transfer on the water discharge. It means if the water flow is to high/fast the is moving too fast to absorb the heat, so valve is needed on the heater discharge water line to slow the water flow down. See picture. When re-piping your system, you want to install a 3-way valve to the line coming out of your filter. This valve will do 2-things: 1- allow you divert water to the pool and to the heater, 2- allow you to isolate the heater and maintain water flow to the pool. I installed a second 3-way vale on the water line going into the heater to allow me to drain water out of the pool. Then installed a standard valve on the water discharge of the heater to adjust the water flow. If your water flow is too high the heater will produce a lot of condensation and drain out of the bottom. The unit comes with a key pad but the Smart Life App makes it a lot easier. Setting up the App was frustrating. You have to link your phone with the Heater and it uses WiFi (not Bluetooth). The heater becomes a Network and you have to connect your phone to that network, then you open the Smart Life App, Add a new device, select smart heat pump, it will ask for network, you will select your home Wifi, enter your password and it will download the heater. What's really nice about this heater, it also cools down the water temperature, yes heating & cooling. Here in Florida that's important because the pool water can go into the low 90 degrees. For my pool (13,000 gallons) it only took 24 hours to reach 86 degrees from 70 degrees. When the heater is running, it only uses 6-amps of energy or 1,300 watts = 1.3 kW which how your electric bill is charged. Using $.06 per kW, .06x1.3= $.078 per hour. If you run your pump 8 hours a day, that's $.62 a day or $18.72 per month. Also, when installing the PVC pipe and fittings, especially the 3-way valves make certain you have them going the right direction and install Unions in you piping to make it easier in the future to work on your system. ... show more

  • Swimming Pool Heat Pump
Size: 5500 Gallons
It is not something that I turn on for a few minutes and then expect the pool to be ready right away by the time I do so. It is most effective when I prepare ahead and allow it to run in a steady manner. As soon as I became used to that beat, it became simple for me to handle. Depending on the weather and the time of day that we want to go swimming, I often begin the process of cleaning our pool either earlier in the day or the evening before. When we finally get around to using the pool, the water has a quality that is far more appealing and consistent than it had previously. Among the components that have proven to be the most helpful in day-to-day usage is the smart WiFi control. In spite of the fact that I did not anticipate relying on it as often as I do, the fact that I am able to monitor and adjust the unit without having to go outside every time is quite useful. Even when I am occupied with other things within the home, I am still able to keep an eye on the setting and make little adjustments as required. Especially when the amount of time spent in the pool varies from day to day, this makes the heat pump seem more manageable to live with. The size of our pool is within the range that is specified, and the heat pump has been able to manage it well while the weather outside is rather pleasant. My expectations were met, despite the fact that it takes longer to make a perceptible impact on days when the temperature is lower or the wind is stronger. We are more inclined to utilize the pool on days when the temperature is moderate since the water is pleasant enough for us to occupy it rather than avoiding it. It is precisely in this area that we have found this product to be of great value. Because of this, the pool may be used for many practical purposes, and swimming will seem less reliant on the weather being ideal. ... show more

  • Junk
Size: 5500 Gallons
Junk! We had one and it worked for about a week. Husband called technical support and they were very helpful and sent a replacement. Husband spent 5 hours setting the new one up and it doesn’t work. Goes immediately to 3e which is an error message. Don’t waste your time or money!

  • Works well, worth the money!!
Size: 5500 Gallons
Delivery was quick and set up was easy. I set the unit up on Wednesday at 8 PM and set it to 80°. It said to allow 48 to 72 hours, but surprisingly 24 hours later my pool was already very warm! As of Thursday at 5 PM my pool is currently 81°! My pool is filled with well water which is very cold!! Before the heater my pool was 70°! I am beyond impressed and excited! I am ready to swim on these cool Iowa days! ... show more

  • Super quiet and great customer service
Size: 21000 Gallons
Great customer service and economical heat pump. More efficient than traditional heaters since it’s a heat pump. Heats the water fast! 4 degrees in couple hours!! So quiet I can’t even hear it! Love this unit and the WiFi app makes it so easy to monitor.

  • Works great, don't buy if you want app control
Size: 5500 Gallons
We've had this for about 2 months now. It has done everything we want for it to. At the beginning of the season it got the pool up to temp in around a day. Now that it is peak season it normally takes about 3-4 hours. We have gotten to use the pool every day this summer, which is a huge difference from years past. The biggest con is the app never works. It's not a huge deal to walk down to it, but when I'm sitting on the deck, I don't always want to walk down into the yard. We have it set on the pool pump timer and plug, so that helps as well. 4 starts because the heater works great, but the app never works. ... show more

  • Great product - worth the cost!
Size: 21000 Gallons
The pump arrived as expected. It has been working very well in our 12,000 gallon above ground. Surprisingly, our electric bill went up slightly, much less than we expected! It has been a wonderful treat to keep our pool at just the right swimming temp all the time. Well worth the money! Would definitely buy again. ... show more
