Perfect product, exactly what I wanted! Easy to install

I bought this for my Sundance Spa. I wasn't 100% certain which heater I needed but the representative in the chat was extremely helpful and made sure I got the exact part I needed! Shipping was quick and the product came in perfect condition. Easy to install and worked immediately as expected. I highly recommend purchasing from Spa Depot. I certainly will the next time I need something.

Perfect fit.

I needed a heater for my hot tub. I looked on line and called my local dealer and it was almost twice as much. I understand a mark up but it was about an 85% mark up. The heater works great and looked just like the original. If needed I will be back.

i would recommend this company for spa parts

I recieved this heater in 2 days which for our rural situation is lightning fast. It was easy to change out and heated our tub right out. This price was half of what we found elsewhere.

Easy install...praying it lasts

Product was easy to install and actually heated my tub faster than the last one. I purchased this from a competitor previously and it died at 18 months. This is a different brand and my hope is this one lasts as long as the original (8 years).

Excellent technical help. The product required some tweaking as it was not a direct replacement but your customer support was incredibly helpful. Thank you!

This heater says it has a titanium element, is the housing also titanium or is it Stainless Steel? I am using salt in this tub and the heater housing keeps rusting through

SpaDepot.com

The heater element is Titanium and the housing is Stainless Steel. Corrosion of metal parts with salt systems can be caused by 2 factors: High salt/water ratio (not very common), or too much chlorine generated (very common). Give us a call and we'll be happy to walk you through the finer points of salt water chemistry so you don't have this problem again.

I have a 3/8 fitting that comes out the top as well. Was wondering if I could sent you a picture to verify. Maybe I’ll need to thread a hole for the fitting.
Thank you for your time.

SpaDepot.com

This heater has a threaded port for the fitting you mentioned. Please send us (help@spadepot.com) a photo of your current heater and fitting, and we'll be happy to ensure you get everything you need for a perfect installation in your hot tub.
