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.

Great Pool heat pump. I have a 15X48 round pool thats approximately 5000 gallons. Setup was easy and quick. I started the pool heater when the air temperature was 70 degrees and the water temperature was 64 degrees. The heater brought the pool to 90 degrees in a day and a half. I always use a solar cover on my pool and that helped to prevent heat loss. For me the cover not only helps heat the pool passively but keeps it cleaner when we aren't using it. Ive heated the pool several times since the first time and its very quick to get the pool nice and warm. I did see an increase in the electricity bill but very little and as it gets into summer I wont be needing to heat the pool. It let us start enjoying the pool in April instead of June and We'll be able to swim later in the year also. For me its a great heat pump and well worth the money. The model I purchased was the WARMBLU H5 hooked up to an Intex 2800SX sand filter.

Bought a WARMBLU H18. Unit arrived in well packaged box with no damage. Delivery was quick via Amazon. I bought this for my 18,000 gallons pool so that I could swim sooner and longer. Unit is able to increase water temperature by 1 degree every 2 hrs of running. It comes in 220V with attached cable. I already have a Pentair Pool controller box so wiring was easy after installed a GFCI 20amp circuit breaker following instruction. Running noise was minimal. Plumbing was also easy with a 3 way and 2 way valves and 1-1/2” PVC pipe. Need multi purposes cement due to both ABS connectors and PVC pipe. There was a price reduction after I bought the unit so I contacted WARMBLU customer service and through the customer representative, I was able to get a price reduction within 24hrs.

I got the 120k BTU . Delivery was fast (2days) this thing is heavy like 220lbs, need 2 person to move around, came in double boxed,very well. Very easy installation straight forward just connected between pool filter and salt cell, it came with 10 gage wire already attached. Once everything connected and secured took me 5 minutes to program and start heating the pool. Dowload the app so I can see the heating progress on my phone. It took 24 hours to heat from 73°f to 92°f very quiet when was running on full speed. Very satisfied. My pool is inground 15k gallons so I bought well oversize so it heat quick and done, it was worth it 24 hours went almost 20 degrees I'm in central Fl so nights in here still around high 50's and low 60s this will keep nice until summer comes and then if it gets too hot this unit chill water too. And the best part the price for the size and quality and finish, great.

the WARMBLU heat pump water heater for the pool, it's quite, and provided with a very good application, through it, easy to turns this device on or off, controlling the settings temperature also shows the detail of the functions, like inlet and outlet of water temperature, amperage of compressor, the speed of the fan, and other functions.

I'm very satisfied with my WARMBLU H10 unit. We had a few very cold days and the unit maintained our pool water reasonably warm. We have a 18 foot round above ground pool. About 8500 gallons. Combined with a pool thermal cover this unit does the job.
