The Spa Heater works great; delivery was excellent. It's much cheaper to buy it in the US and have it shipped to Canada. ☹️

The original (20-year old!) heater was still working until I installed a temp sensor incorrectly and accidentally dry-fired the heater. So I was very pleased to find this unit with a Hi-Limit Sensor included for the price. The one thing they don't say in the instructions is that the new high-limit sensor isn't supposed to seat all the way in as the old one does. But SpaDepot's support was great. They confirmed that it just needed to be caulked with some silicone to hold it in place. (See pics: old heater/sensor on the left, new units on the right.)
And, many thanks to John Reihing, who described in his review on this site how to keep from dry-firing it. Because of him, I was able to self-install with confidence.

Super fast transaction and best price around

My old heater started tripping my circuit breaker, so I checked the continuity of it and it was bad. So, I shopped around and found that SpaDepot had the best prices, by far, on a replacement.

The replacement arrived in great shape with good instructions. I watched a video on YouTube that helped me better understand how to disconnect the old one and connect the new one. The video was very helpful. I did the installation myself and everything seems to be working well. Overall, very pleased.

Perfect replacement works great.
