This 2013 No-Fault PDR Titanium Heater is the newest factory upgrade replacement heater from the makers of Hot Springs spas. Its double-pass sleek design replaces all previously discontinued heater styles. The double-pass feature efficiently heats the water in two stages and oh what a perfect job it does! Now factory approved and warrantied for all 115 volt 1.5kW and 230 volt - 6kW installations for all 1995-now Hot Springs and Tiger River spa models. Your existing 3/4" vinyl tubing will attach to this heater with no worries. The thermistors have different thread sizes to insure they can't accidentally be reversed when re-installing them into this new PDR heater. The also have different tips on the ends of the wire to insure they can't accidentally be plugged into the wrong port on the IQ Control Box.
This replacement heater doesn't have a plug on the end of the power cord like on the 1995-1996 spas. In most applications, the heater is connected directly inside the spas control box. If your existing heater plugs in to the bottom of your control box, you may need the appropriate adapter. Adapters are listed next to your spa model on the chart below.
Note: The 73791 can be used as an alternative to this heater, however, in a 115 volt wired spa the one third less heating capability (only 1000 watts) of the 73791 is inefficient.
Tip: You can also utilize the cord end (plug) from your old No Fault heater and splice it onto this new PDR if needed.

Note#1: This PDR (power-down-reset) heater eliminates the manual reset button, which means that you never need to remove the equipment door to reset the heater. Simply power down the spa for 30 seconds by either tripping off the GFCI breakers in the sub panel (on 230volt models) or unplugging the spa (115volt models). Yay for this massive improvement! There is something about the manual reset circuitry on heaters that causes them to die prematurely. This heater replaces all heaters in all 1995-now Hot Spring, Tiger River and Limelight hot tubs which includes the No Fault 6000 heaters, Watkins No Fault 5500 and the No-Fault 1500 cartridge style heater.
Note#2: The inlet thermistor port on these style heaters require a wrench to thread in the thermistor.
Replacement Hint: It's easier to replace a heater if the spa is drained. However, some folks leave the water in the spa, disconnect the vinyl tubing from their old heater and insert wine corks into the ends of the vinyl tubing. This insures a minimal amount of water loss during the change out. Repair techs use radiator hose pinch off pliers to clamp off the tubing.

Great troubleshooting guide on your website helped me diagnose the problem with the heater relay board in my hot tub. Emailed your tech dept. with results and the tech sent back a confirmation along with a link to the exact part I needed. Very fast shipping and it took ten minutes to fix the problem and get hot tub hot again once I got the part. Definitely keep you folks in my favorites list.

This was without a doubt, my ABSOLUTE BEST online experience EVER!!! Backyard Plus has outdone any other site I have been on with their comprehensive step by step diagnostics with photos on the Backyard Plus website that helped me to debug my hot tub heater issue and narrow the failure down to the specific board I needed. A smooth and speedy ordering process had my part here quicker than I expected and I was easily able to replace the part myself fixing my heating issue & saving me hundreds on what would have been an expensive service call from a local hot tub service company. I am now a loyal customer for life!
Pump was delivered promptly after I placed the order. After pondering the replacement for a week or so, I performed the deed without any significant problems. It has been working perfectly for about 2 weeks now. Thanks!
I love this site. It has exactly what I need for my specific spa and the parts are always delivered fast and correct.
Thank you so much!!Rochester NY is Freezing and my whole family loves to be able to sit outside in the snow and enjoy the Hot tub!! We have an older hot tub, and we are very lucky you still carry the parts.!! Merry Christmas!!!!
My part was easy to find and fit perfectly. Every thing needed was included as were the installation instructions. The check to see if it fits your model is a big plus.
I have purchased spa parts from Backyard Plus for several years. They always have the parts I need at a good price AND they ship fast. I dont want to have that spa down too long. In separate orders in the past several years, I have replaced two different electronic circuit boards, the ozonator and a check valve. Just writing this makes me want to stop and go sit in that nice hot water . . . Thanks Backyard Plus.
I did not know what I was doing with my Hot Tub until I got on Backyard Plus website. This website is AWESOME.. Just enter your model number and they show you what you need. I do not even look at my factory manual anymore, I come to this site. Then to finish, they ship right away. COOL
