Features
- [Efficient Heating Tube]: The electric pool heater is equipped with 304 stainless steel heating tubes, which provides excellent thermal conductivity. This efficient heat transfer through the heating tubes speeds up heating times and lowers energy costs.
- [Touchscreen Display]: Compared to traditional temperature knobs, the upgraded touchscreen display on the 11KW pool heater improves visibility and control. The temperature is visually displayed and can be more accurately controlled with ease.
- [Automatic Circulating Heating]: The swimming pool heaters will cycle on and off based on the preset temperature. When the water temperature reaches or surpasses the preset level, the pool thermostat will automatically shut off. Conversely, if the temperature drops below the preset level, the pool thermostat will automatically turn on again.
- [Professional Wiring Method]: Since a hot tubl heater is a high-powered machine, it is designed to be hardwired rather than plugged in. Therefore, it is important to have a licensed electrician handle the installation process. They can ensure your safety and proper wiring to maximize the efficiency and lifespan of your pool heater.
- [Notice]: 9KW Pool heaters are suitable for pools of around 1000 gallons. In addition, the heating time of a pool heater depends on various factors such as the size of the pool, the desired temperature increase, the power of the pool heaters, and the ambient temperature.

Works great, would definitely buy again. To get it to heat large volumes of water quickly, you need to understand how the controls work. It seems to ramp the temperature up based off temperature difference vs just a simple on/off method. So you have to max out the temperature setting to get it to heat fastest then just turn it down once you hit your set point.

Works perfect. Bought to heat up a 8ft stock tank pool. It will turn 700 gallons into a 100 degree hot tub.

The media could not be loaded. I purchased the Mxmoonant Pool Heater (11K, 220V) back on June 20th, 2025. It had been working fine until recently, when a component in the heater failed (overnight), causing half of my pool water to leak out and the pump to run dry, ultimately causing the pump to fail. Water is still dripping out of the heater. (See video of remaining water leaking out)

I have had this working for a few weeks. It heats ok. Takes my 600 gallon tub about 8 hours to heat up from 50*F to 104 *F. The 9kw requires number 6. The big problem I had was connecting the 6 gage wires to the terminal block in the unit. The terminal block is way too small for number 6 stranded wire. Major hassel.

Update: Seller is very understanding and communicative and has resolved the issue to my satisfaction. Does not heat up to listed temp. Had to have multiple electricians come and finally installed a new Wire connector hub because the metal tabs in the attached hub did not allow the gauge size to fit through. It needs to open up wider or it doesn't grasp the wires properly. Even still, after replacing the connector hub it only heats to around 102 and never reaches full temp before it shuts off the heating process. The services I paid for cost more than the unit itself and not worth returning for the same issue to be met with a new unit. The instructions are not super clear and I am worried that this will not last outdoors so I had to purchase an additional custom cover to fit this with all the placement of the PVC and wires. I cannot say I fully recommend this heater. Hopefully it lasts longer than I expect it to.

Performing admirably. I don’t think you can go wrong with this. The building flow detector is awesome.

The 18kw did not work for pool or hot tub use in the USA based on not having a ground fault that met the requirements in the USA. Maximum amperage for gfi is 60 amps. Manufacturer sent me the correct unit (11kw) free due to this issue. Great customer service.
