  • Great baptismal heater. It gets HOT!
This heater and a cheap bubble thermal cover is all you need...and a 240v outlet! I searched for a baptismal heater for our church and I didn't want to drop $500 for an advertised drop in "baptismal heater." We used a 120v bucket heater for about a 2 yrs until it died. That one would go on at 6pm Sat eve and would basically take the chill of the water by Sun 12 noon. (Florida ground water usually around 72°) This 240v heater goes on at 6am Sun and is like bath water by 12 noon! You need 240/220v to make it work that good. It comes with a 120v adapter plug, but will heat a lot slower. Baptistry is 90"x40" and about 40" deep. If you have a smaller baptistry, it will heat faster and hotter. It does make noise because the element gots hot enough to boil. ... show more

  • PassOn This One
This item is useless. I purchased it to heat water in my whirlpool tub, but after over an hour of submersion, there was no discernible change in the water temperature.

  • A MUST FOR BIG BATH TUBS. Easy to use.
I just had my bathroom remodeled after 30 years. The most important thing for me is bathtub as I soak almost daily. Unfortunatley, I run out of warm water before the tub fills. I found this on Amazon and was skeptical but went for it. Its AMAZING! I fill the tub about three inches, put it in and wait for tub to fill. Once tub is full it takes about 20-30 minutes to be pretty hot. If you keep it in the hour, you’ll cook yourself so be careful. It’s a powerful device! I love it! ... show more

  • Not strong enough
It is not strong enough to heat up a jaccuzzi 120 gallon... I also wasn't strong enough to warm up a 50gallon Bath tub in 6hours.

  • No issues
Definitely wish I had this a loooooooooong time ago. The ease of use, simplicity of it and how it does what is needed to do. I was definitely impressed when my gas was off for a few days…a diva has to have her bath💜

  • Portable heater
I used to heat a portable hot tub. Although it heated the water just fine. It started to rust and corrode within one month.
