- The water spa heater thermostat stabilizes the water temperature between 0-45ºC (32ºF~113ºF). The thermostat will automatically turn on or off depending on the temperature you set. If the temperature exceeds 60ºC/139ºF, the heater will stop working and the reset button will pop up and cut off the power.

## Customer Reviews

### ⭐ Im confused
*by R***E on May 14, 2025*

220 volt heater with 3 wires: one hot, one neutral, one ground. The neutral is not the second hot. How's that work?

### ⭐⭐⭐⭐⭐ So far so good!
*by A***R on May 1, 2024*

I purchased the 220V pool heater for my 6’ stock tank pool. I insulated with foam board underneath and wrapped it twice with foil insulation. Im using a pump and filter from Doheny so flow is not an issue like similar reviews using the Intex. In a matter of hours my pool increased by 10 degrees. It was very easy to install and so far no issues. Very happy with my purchase so far.

### ⭐⭐⭐ For temperature control, not heating.
*by B***S on January 20, 2025*

This little heater is fine for a small amount of heat input. It is useful for maintaining a constant temperature. If you have a hot tub at 39c it can hold that temp. If you have a hot tub at 25c, it will take days to achieve 39c. 400 gallon tub gained 4 degrees in 10 hours, drawing 14 amps the whole time. We use a propane water heater to get up to temp, then this heater and a 1/4 hp pump to hold the temp.The pump is plugged into a programmable PID to keep the water at ~30c when we don't expect to use the hottub for a while.
