Welcome to our forum.
My wife and I got in last night. The outside temp was around 27. Not quite as cold as the last night. I turned the air off and just ran one pump. THe water temp maintained with no problem at all. I hope we get another few reaaally cold nights so that I can test the air being off and running both pumps in those conditions. I have full year warranty and if there is a problem I might not know till its too late.Jaccuzzi Jim, I'll check this evening to make sure the heat is on with both pumps but I think is was.On another note. And Im sure this has been covered extensively. But is it most cost efficient and better for the tub to keep the temp at 102 or if your going to use it sporadicaly wouldnt it be better to turn it down 10 degrees or so and turn it back up an hour or two before use?
I keep my tub around 98 when I know it won't be used for a while. You don't want to drop your temperature too low in the winter in case you lose electricity or something goes wrong.
