Mxmoonant Pool Heater 11KW 220V, Electric Swimming Pool Heaters Hot Tub Water Thermostat with Touchscreeen for Above Ground Inground Pool, Spa, Bathtub,

Works great

Wiring instructions for 110 vs 220/240 are the same which makes no sense. Had mine wired to 240 @ 60A breaker with 6 gauge wiring with 1.5hp pump and 1.5” pipes. Output of heater no different than the input water temperature. (Ambient air temp is about 75f and set water to get to 82f. After two days running water started at 69f and stayed at 69f). Wasted almost $1000 just for electrician and plumber (with their supplies) and this thing is of no value. Removing and returning it.

No issues besides the flow rate. Heats up my hot tub takes about 15 min

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.

UPDATE. 1 year later (May 2026)........it worked great for a year, then died. from what I can tell the heating elements went bad. ORiginal review from 2025: 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.

Brought this to our home in Isla Mujeres Mex works incredibly well! So happy with this heater.

Wonderful for our small pool.

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 bought this heater for my Jacuzzi back in October. When it arrived the Display stopped working right away but they quickly sent me another one and that fixed the problem. It worked for about a month and the heating element failed. Jenny once again quickly sent me a complete new unit this time and so far it's working great and it's been a few weeks. Great customer service and I recommend this heater as it really does heat the jacuzzi nice. Compré este calentador para mi jacuzzi en octubre. Cuando llegó, la pantalla dejó de funcionar de inmediato, pero rápidamente me enviaron otro y eso solucionó el problema. Funcionó durante aproximadamente un mes y el elemento calefactor falló. Jenny una vez más me envió rápidamente una unidad completamente nueva esta vez y hasta ahora está funcionando muy bien y han pasado algunas semanas. Excelente servicio al cliente y recomiendo este calentador porque realmente calienta muy bien el jacuzzi.

Hice la instalación eléctrica de acuerdo a especificaciones, comprando la bomba tubería de la medida, funciona el panel, pero el agua no sale caliente,

excelente funciona super bien

Compré este producto y desde un inicio botaba las pastillas se le puso una pastilla de bastante capacidad la que lleva ahorita no recuerdo el número exactamente es la de más aperaje que venden en una casa eléctrica. Resulto que ya no prende compré la garantía extendida pero es digital la mandan por email no aparece nada, aquí en Amazon es difícil dar con el vendedor o alguna atencion a clientes por eso opto por escribir aquí ver la manera de resolver un cambio o alguna devolución.
