It seems as though my water heater stops working when it gets cold out
(40-55 degrees). The unit is new, and it is inside of the house. This is an

separate 240v lines coming in as well as 110v.

Also, the timer went totally bad, the problem was not just because the timer
was off from 1-8pm. I forgot to mention that, I am going to have to follow

bushes, so I didnt get a close look when the electric company was replacing
