I drained and refilled my tub this morning. Turned it on at 11am and the water was 55*. At 6pm when I got home, it was 97*. Checked when I got home from TKD a little while ago, and it's at the 101* set point. Outside temp is 37*. I'm heading out for a soak in some nice new, clean water. 8-)
I'm usre you will be enjoying your soak tonight as well. Congrats on the tub!
