Bill your not supposed to have it on Celsius...
I matched you. The water is sitting at 42. I hope it will be ready by tonight. It finished refilling at 1:00pm. I will let you know how long it takes to refill
I think I put my heat back on around 10:30am and when we got home from the Bob Seger concert at midnight it was around 97. Thats about the 4 degree per hour norm for this tub.
