I would buy this product again

I purchased the spa heater and am very satisfied with the purchase, delivery, and performance of the heater. Any questions I had were answered by representatives of Spa Depot. Everything went as planned. And heater is performing as it should.


Perfect replacement and easy to install. Was delivered promptly.

Spa repair

Heater works great!

Great service and support.

Heater workd, no problems.

I bought this heater thinking the one in the spa wasnt working. After installing it I realized it was the control panel. But this heater worked just fine once i installed a new control panel.

Robert Gray
Pleased with the service and performance.

As a DIYer I am not overly familiar with the pieces and parts that make up a hot tub. I knew that we needed a heater replacement. I found this one at spa depot. The price was very fair and the shipping was prompt and timely. Our old unit was equipped with a pressure switch. This unit did not come equipped with one and did not have a bypass attachment. It took several more hours of research to figure out that we either needed to add an in-line pressure switch or purchase a pressure switch bypass. This definitely could have been made clearer.

I would definitely buy this

Fast delivery, easy to install. Installed this same heater in two of my Hot Springs Soverien hot tubs and they both work great.

I know where we are buying it at again if we need to

It was fast and came all in one piece works really good heats the water to the right temperature and easy to put in

Great heater replacement

Works great. Easy install
