We haven't used the tub much this winter due to bitter cold and wind. We're finally getting some moderation in the weather, so we've used it more lately. We have a Jacuzzi J345, and I normally have the temp set at 100 or 101. This has happened a couple of times recently, and I'm confused. We get all ready for a soak, head out to the tub, lift the cover off, and the temp reading is high...106-110 degrees. When I hit the temp button, it reads 100 or 101...normal. I felt the water just to check that the temperature control is not reading incorrectly...sure enough...hotter than I like. So tonight I even put a thermometer in it because I just didn't believe it was 110 degrees, but sure enough it was. Hot enough that we shrugged and went back in the house disappointed. I left the cover off to let it breathe a while. I've owned the tub 2 years, and this has happened two or three times since we've had it.
The air temp here was 35 degrees and sunny, and it's now down in the high 20's. Either I have a damn good insulating cover, or something else is going on. Is this normal...do other Jacuzzi owners find this same thing happens?
