We're in the market for a used or new hot tub. One thing we're
concerned about is the maximum operating temperature. It looks as if
all hot tub thermostats are now capped at 104 degrees for safety
reasons. That would probably be OK for me, but for my wife who likes it
hot, hot, hot, that just won't cut it.
We have an indoor jacuzzi tub now, and she gets that above 110 for her
tubs. Granted, there's no heater, so the water starts cooling off
immediately - but it's still above 104 after 20 minutes of soaking.
We've measured water temps in other tubs and hot tubs and I think
somewhere between 106 and 108 would probably be ideal, but at a max temp
of 104, it won't be worth buying. My wife's parents keep their hot tub
at about 112. Ouch! That's too hot for me. I can last about 5 minutes.
So, my question is not about the health effects of such hot
temperatures, but rather...
Is there a simple way to hack the thermostat on a hot tub to get above
the 104 cutoff? I was thinking of maybe covering the temp sensor with
some kind of insulating material, but I'm not sure if that's feasible.
Since we don't currently have a hot tub, I'm not even sure where the
temp sensor would be located.
Has anyone successfully hacked their hot-tub thermostat, and how did you
do it?
Thanks.

On mine (Gecko controller), you can get to 106 by holding down the temp-up
button after you've set it to max temp. Good luck!
