So how I use this for our bathtub because its it’s huge and I have a small water heater so I filled the tub up with lukewarm water to cold about a quarter of the way I let it sit in there for an hour till 98.9 and then I fill my tub up the rest of the way with hot water and it works really really well now it does take a long time I knew that going in. I’ve had one before, but this one’s really big I feel that it works well to me. It warms the water a lot faster, and even still a hour my last one would have cold spots ..I’d recommend this to anyone trying to do a bath tub. The thermometer also works well. I also saw that it didn’t last a long time so I got a three year warranty on it if it crapped out.

Well, I got this device in November and it did wonderful heating the water. The device 4 months later was busted somehow by being in the water so I reached out to the seller and send pictures of how the device looked and got a quick response with them sending me a replacement that will arrive in ten days. Great and speedy customer service. Five stars for their effort.

I have a fairly small in ground pool. I left this heater on over night but it didn't increase the water temperature even one degree. I returned it.

Build quality is good. It works BUT, I have no idea how people are saying it heats a cold bathtub from cold water to 104 degrees in an hour. When I put hot water in (98 degrees according to included thermostat) and set the unit to go up to 103 it takes at least an hour! So, 5 degree increase takes at least an hour in a standard size bathtub. So, it works. It’s just VERY slow.

Very easy to use, works great, and lasts a long time even with weather. Perfect size. Only problem we had was even though it warms the water I suggest getting some type of top to keep the warmth in. If we had a top to keep the heat in it would have been worth the money we spent on it.

Amazing heater for inflatiable hot tub ,really ! The pump on my 14 month old hot tub went out of which the heater went out just a matter of 2 weeks before . So instead of paying another 4-5 hundred dollars to replace it ,I bought this heating e!cement and the temperature probe that regulates it .. It took a few hours to bring it up to the desired temp as it was a cold 58 degrees to start , but at 80 degree it was less then 3 hours at that temperature and the range does go higher then the heater in the inflatiable tub motor . So I set it at 105 and just unplugged the heater from the temperature probe outlet ..I can watch that to see how fast the temp drops and plug the probe in if I need to .So far the temperature has held longer then I thought it would .. Just remember to unplug the probe before enjoying the hot tub ... Note: the probe cools fast after it's unplug and you can take it out and set it aside.. while you get in . I put the cover on and put a couple of blankets on that to help contain the heat ..while it's heating up .
