Description

With an output of 20,000 BTU, WOPOLTOP pool heat pump is specially designed for above-ground pools up to 6000 gallons or in-ground pools up to 4000 gallons, hot tubs, spas, etc. The operation only requires very limited electric input, hence its high efficiency and heat conversion rate can reach a score of COP 5.0. Air 78.8℉, Humidity 80%, Water Heated to 78.8℉ Air 59℉ Humidity 70%, Water Heated to 78.8℉ Common Error Code Explanation: E20: Water flow failure. When the machine senses that the water flow through is insufficient, it will report an error, and it can be manually/automatically restored after determining that the water flow is sufficient. If you come across other code, feel free to come to us and we'll help you solve it. Temperature control system can keep the pool temperature at a consistent level. Easy to set up digital panels provide quick access to unit controls. Child locks and advanced protection systems make use of the pool more convenient. This heat pump model is designed for 120V/60hz, easy to operate standard 3-pin, 120V plug, can be used for US electric, direct plug operation. Equipped with fuses, varistors and strong electromagnetic compatibility protection. Designed for heating above/underground swimming pools and small indoor swimming pools. The steel chassis is designed to withstand year after year. The waterproof profile is designed to accommodate a variety of placement options. How to set the temperature difference are as follows: 1. Look at the LOCK light on the panel first. If the LOCK light is on, press and hold the switch key until the LOCK key blinks and then release. If the LOCK indicator is not on, skip this step 2. Then press and hold the M key until the SET key blinks quickly and then release it (the SET key blinks slowly when it starts blinking). 3. When d1 appears, press M to display the temperature difference. After adjusting the temperature difference value, press the M key to confirm, and then press the M key for 3 seconds to exit 1. Keep the pump upright for more than 24 hours before using it to wait for the contents to settle, because it is maybe upside down or on the side during shipping. 2. Each pump is tested with water and electricity at manufacturing before the sale, so there will be little water, which doesn't represent it is used. 3. You need to confirm your water pump, and the advised water flow of our mini heat pump is 600 - 850 gal/h. 4. When the pump works properly, there is a temperature difference between the fan outlet and the back air inlet, and also a temperature difference between the water inlet and the outlet. 5. If you want your pool's temperature to rise quickly, having a solar cover covering the pool at night is helpful. 6. It is helpful to take some photos or videos when you have any usage issues. In order to ensure the continuous, stable and efficient operation of the products, WOPOLTOP goes through long-term rigorous field testing.

  • It works fantastic.
As a Michigan resident, this is going to extend my pool time! Works great. Relatively easy to install.

  • Don't waste your money
Very disappointed in this product. Problems from day one. Constant error codes, customer support is nonexistent.

  • So far so good.
Water temperature went for 60 to 72 degrees in lest than 24 hours. 14 foot summer waves pool. Kids can't wait to swim. Would definitely recommend.

  • Wouldn’t even start!
Was really excited about this pool heater. However when it was turned on we only got clicking sounds, so we couldn’t even trouble shoot. It should be noted we sent it back and Amazon was fabulous! The delivery company was not! We told them it was heavy to use a hand truck. The driver “dropped the unit twice” which caused my packing to come undone which was screwed into the wood packing base. If this is how pick up goes, it may have been more damaged before delivery! Very sad! ... show more

  • good choice for summer
For me, it was a good investment for the summer. It does not come with a hose, and also has to prepare a small flow rate of water pump to use, of course, these are not a problem. Even if I am not a professional, the installation can be completed very well, it needs to be noted that the connection should be fixed in place, otherwise it will leak. It's a bit heavy though, and needs to be dragged to my yard somehow. Everything went smoothly after getting started and operation was simple, it automatically heated and turned off to maintain the temperature I needed, and it was really great for my 5000gal pool! ... show more
