Going above 104 deg.

[patorhank]

Hi, and thanks for lots of help in the past.  We were searching the forum for help with an error message on our Jacuzzi J350 (FLO2 message- we found we could shake the flow switch and it started working again) and we came across some references to jumping the temperature limiter and being able to go to 108 deg.  We don't want to go that hot, but would like to be able to set the temp at 105 or 106, especially in the winter. I contacted my local spa repair guy (and authorized Jacuzzi tech ) and he didn't know anything about this mod. He called the Jacuzzi Rep. and was told it is possible, but they were not allowed to reveal how to do it.  So can anyone here share with us how I can do this modification myself?  Thanks

Don't know about Jacuzzi but there were a couple of threads on the subject recently.

Maybe that will be helpful? Others here may have more detailed info on raising the temp. Haven't had my own spa above 102 yet and don't know that I need it any higher, at least not now with the warmer weather already here.

Be carefull, there is a reason why U.L. specifies 104 degrees as the max.  If you sit deep in the water for long enough, your temperature will be the same as the water.  If you go over 104 you are hurting yourself.  The higher the temp - the shorter the soak.

I live in Iowa and as you can imagine winter temps get pretty cold.  I think changing your temp above 104 is bad news.  I have mine wired as a 110 and I have not seen any reason to go above 104.

I think you are messing with something you don't need to.

Free country though......... :-/

I've done 110^o for > 1 HR in one sitting.

True, it was 27^o out with a 20 MPH wind and ice was forming in my hair (along with the 4 other people in my tub), BUT what a soak!

I wasn't really "HOT," after all 50% of body heat is lost through your head, but when I got out my muscles were like jelly. When I hit the bed, I couldn't even feel my body. The next morning, I woke up so refreshed I couldn't believe it.

Unfortunately, this winter didn't get cold enough to go to 110^o. 107^o was as high as I got it. I'd be careful going over 106^o anytime it's above 50^o outside. With cold air, I've found you can generally tolerate higher tub temperatures.  If you try it, EASE into it gradually and drink plenty of water....

I had mine set at 102 degress,but it had to be around 108-110 because of a bad switch.....I would not go over 104......Anything over you will be burning in a pot of soup ...JT

[patorhank]

We are aware of the dangers of soaking TOO long in TOO hot water. We don't intend to run the temp up to 108, but would like to be able to go to just 105 or 106 on some occasions. Or previous tub was an older Cal Spa and we could run it up to 110 easily, or even higher. When I would be particullarly sore after a very physical day, a few minutes at 108 or so sure did loosen up my sore muscles.

So is anyone willing to share the secret of jumping the temp limiter? Please...

[johnnythunders]

Hummmm if yea have your spa up at  108 -110 I would think somebody should put a little salt and pepper in your spa and in 30 mins you will be done.......JohnnyT

I wish I could remember how it was done.  I know it involves tripping the breakers on the circuit board.  

In the cold of winter i had my tub at 107 and I loved it.  It was really hot but very nice in the cold canadian climate.

The other day I dropped the tub down to 100 with the nicer weather

I just brought a J315 jacuzzi and asked the dealer about raising the temperature... they said it could be done but because of liabiliy, I would have to have a Doctors Rx... then I would have to contact Jacuzzi home office to sign liability papers and then it would be very costly.... Geez... And I LOVE it about 106....   Surely SOMEBODY on this board must know how to do it..

Can anyone refer me to any actual studies, documented medical studies (not opinions), showing the dangers of soaking in water above 104 degrees?

[Gomboman]

Doc, doesn't your friend Bob Lowry have some info on this?

Here is a link to an article on the website of the CPSC.

http://www.cpsc.gov/CPSCPUB/PREREL/prhtml79/79071.html

It is an old article, but I believe it is still relevant.  An excerpt from the article:

"Soaking in a hot tub with water heated to 106 degrees Fahrenheit, for example, can raise human body temperature to the point of heat stroke (or impairment of the body's ability to regulate its internal temperature). These conditions can be fatal even to fully healthy adults."

I ironically , I had a nice 20 minute soak at 106 today. Somebody accidently bumped the panel getting out of the tub and turned the filtration up to 24 hours, so it was running overnight continously.  Since it was in the high 30s this morning it felt great for my short soak.

 I'm fine with the limit of 104 on the Optima, but it makes you wonder why that's such a big deal when anyone with access to their water heater could easily crank it up and fill their bathtub with 140+ degree water.  Sure, it'd gradually cool down, but I bet you'd get a nice long soak at temperatures well in excess of 104.  No warnings on the tub, and the only warning on the water heater are about scalding.

There has been plenty posted about the way to adjust the jumper on some Sundance tubs to get the temperature above 104, but I don't recall anything specific to Jacuzzi.  If they have similar control boards, maybe the process is the same?
