The required heating time varies according to the environment and water temperature, so it is recommended to fill the bathtub with hot water instead of cold water to reduce the heating time(better with an insulation cover).

If temperature exceed 60C(139oF), reset button will flick out and cut off the power, needing manual reset.

  • Works great for a small pool.
I have a small 12' round pool, about 30" deep and it heats it up nicely. Couple things, Make sure you have a dedicated 20 amp outlet for this as it can draw up to 18 amps. Also make sure your pump has a strong enough flow to activate the switch. Easy way to do this is with an ohm meter. When you have the heater hooked into your system and turned on you should have resistance at the wires, if you don't your flow is not strong enough to trip the switch and you will not get any heat. ... show more

  • worth the money
hi, this is a long details review, mainly the info i couldn't find online when i was searching to buy a pool heater. i have a 16 foot round above ground pool in the NJ area. without heater the water had been very cold and for a past 3 years i have been trying different things to get my pool water to heat up. i tried the solar heater, which only heats about 2 inches of of the water and the remaining water is cold. i tried the solar hating mat and that didn't work. so i wasn't going to put up my pool. when my son gave me the suggestion to use the spa heater for the pool. i did some research and found this heater but no info on if it would heat the 6000 gallon pool. the details state that it won't but i gave a shot anyway. i had to run a new line to the pool. because the existing like was 14 gauge and 15 amp breaker. for this heater plus the pump and light i would need the 30 amp braker. i ran 10 gauge wire with 30 amp braker. i decided to use the sun screen to keep the heat in the pool as it heats up. my starting temperature was around 60-65 degrees. which is cold. i ran my sand pump and the heater for 6 hours a day in starting in the morning and in 2 days the water temperature had reached around 96 which was perfect for kids for enjoying. the heater is small size and the max temperature it will go is around 113 degrees Fahrenheit which is for a spa, but for a pool this size i think if it is able to, it will take it to above 100 degrees Fahrenheit it is perfect. so from my part this device works and i fully recommend. i will add images when i get them. ... show more

  • hot tub heater for indoor
i hooked this up to a 3kw solar inverter with a 48 volt 50ah battery and solar array, it pulls 2200 watts and the pump pulls 400 watts. even with the pump not connected to the solar circuit and limiting to 2200 watts it reboots the inverter after 3 or 4 minutes of use. this is a good idea providing your power source can handle the load. this can’t be ran on typical home wired outlets it trips a 20 amp circuit quickly. of i could find a 1500 watt element i would review and provide my setup. ... show more

  • Heats
This works well for a small pool, around 1200 gallons. It heats well so it can most likely do one slightly larger. Getting the correct fitting combination was a challenge to say the least. Some came from a big box store, others from Intex(leaf filters). The picture shows the combination that works without leaking. The blue is a plumbing thread sealer. This unit requires a 30amp circuit and low pressure to work. Maximum pressure is around 40psi which is double of what most sand filters are so if you keep your pool pump and filter clean there shouldn’t be an issue. I would recommend this for a smaller chilly pool or spa and plan on using this unit for years(extended warranty). The unit has a flow sensor inside so you need a decent pump to trigger the heat. ... show more

  • Great product to keep your pool warm.
When I originally ordered this. I thought it was an inline water heater. And I was going to use it in my RV. But it's not, it's a heater for pools or hot tubs or Bath tubs if you want to kind of make a Bath tub into a hot tub. It has a thermostat that will turn the device on and off when the temperature of the water gets too low and keep it maintained at the temperature that you have preset. It was very easy to install. Didn't take long at all.. It does a really good job keeping the water warm. I do recommend this product. ... show more

  • Really worked
I put this in line with a small sand filter and an 8' diameter 40" tall kid pool . Say pool was 68°f and temperature was 70°f over night this would have the pool up to 84°f by morning and 90°f by end of day so I'm happy and the kid loves it

  • Worked maybe one day!
I had to return it because it may have worked one day I don't think it ever fully worked at all I ran a special cord for it direct wired it in so I know that the voltage was good but it just didn't work properly. They did refund my money sad because I was really hoping that it would work.
