I looked at it today and it was set on 100 I moved it up to 125 because it seem it took to long to reheat. What is the correct setting? I don't want it so high as to injure someone!
How much does it cost??
Answers:    120 won't do a great errand washing dishes. I set mine at 140. It can make happen burns, but not instantly. I have plenty of time to act in response if I have the hot/cold mix too hot. I enjoy no children living here so burning them is not an issue.
Does anyone know how to store a box...
whatever you want ... most form codes say 120F or below to prevent scalding
