It fit my Hot Springs tub and came with new sensors. Quick delivery for our well used hot tub. 18 hours from 55 to 101°f... Yea!

I received this heater as a warranty replacement for the original one that I purchased that failed in the first 2 months while still under warranty, and it failed in less than 2 months and Amazon said they couldn’t send another replacement even though I purchased a 2 year extended service plan. There is obviously some defect in the heaters they are selling. Now I am faced with freezing weather and a bad snow storm approaching and the fear of my hot tub freezing.

This replacement heater has been a great upgrade! I was pleasantly surprised by how fast it heats up and how much of an impact it made on the overall temperature — the difference was noticeable almost immediately. Installation was straightforward, thanks to the clear and detailed instructions provided, making the whole process smooth from start to finish. It’s been working reliably, and we’re really happy with the performance so far. If you’re looking to swap out your old heater, this is definitely a solid option we’d recommend.

Product seemed fine, but the terminal ends do not match my ends for my 2005 caspian hotspring, make sure you get one with the image attached. This one came with two four prong terminals and mine needs 1 4 prong and 1 2 prong like pic attached. It was well packaged and arrived quickly but I had to return for one with the pictured terminals that this one did not have.

This heater only lasted a month. Terrible

Installed this in my hot springs spa. It worked as it should and now I’m up and soaking again.

Replacement heater has worked well. Surprise how quickly it heats up and how much of a difference it has made in the temperature used easy to install. Great instructions. We recommend for replacement of your heater.
