Hot Spring Heater Replacements

Hot Springs replacement heaters for all 1995-now spa models.

In 1995 Watkins introduced the first No-Fault heater. The name "No-Fault" means that there is no longer any mention of  negligent water chemistry voiding the warranty. In 1997 the second version of the " No Fault" heater was introduced and remained in production until late 2003. The third version of the "No-Fault" was utilized in the Tiger River spa line with some Hot Spring dealers using it as a replacement heater in both Hot Spring and Tiger River spas. The fourth version of the "No-Fault" was introduced in 2004 and has proven to be the most solid design we've seen to date. This PDR (power down reset) Titanium heater style is used in all Hot Spring & Limelight spas rolling off the assembly line today.

Your 1995-2004 original spa heater should look like one of the three heaters shown below.
