Thanks. That is pretty technical for me, but maybe I can get an electrician on it.

I would think you are right,no heater in soft tubs so the heat you can get from the elec. motor is probably all you get.Maybe you can rig up a spa heater some how. The older Softubs get up to 115 with a simple modification, so I am sure it has the ability to do it, but has been regulated to stay at 103-104 degrees . Anyone have any ideas other than the woodfire? I little too high mainainance ;-).

Are you a mind reader? I have all the same questions . I used to go to a friend's redwood tub, and he added 10lbs of baking soda and 10 lbs of epsom salts to the water. It was wonderful. Just totally drained any tension from the body. My additional questions would be is there any effect on the motor or the vinyl liner (Softub)?

Hi all. I just got a newer Softub 300 with the Ozonator and digital control pad. I love it, but it only goes up to between 102 and 103 degrees. I am a longtime hot springs guy, and I am used to Harbin Hot Springs hot pool which is between 114 and 117, so this thing is like luke warm to me. Contrary to what the government thinks, many people believe in freedom of choice about tub temperatures. Please no comments about how dangerous higher temps are. In cultures all over the world for hundreds of years humans have been getting into super hot water with no ill effects, and fertility is not something that I am worried about. I have been soaking in 115+ degree water for 25 years. You just stay in shorter time periods. OK, off the soapbox . What I really am looking for is a solution to get my Softub cooking at 10 or more degrees higher than it comes from the factory. I am sure someone has figured out how to do this, but I can't seem to find any info on the web about it. The older models had a screw that could be turned for higher temps, but I cannot find any info for the digital models. Anyone know how I can get this thing hotter?
