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
electric unit, and we replaced the unit because of these same symptoms. It
is on a 240 line, all by itself. If anyone has any ideas, I would be
Measure the voltage across the 2 wires going into the heater
(should be 240V). If zero, maybe the breaker is failing
or some splice/termination is open.
How is the heater fed and what does the breaker arrangement look like?
Thanks for the quick response. OK this is weird, but i put my AC meter on
the outside of the 240v breaker, and I get nothing. Very weird! The circut
is 240v, nothing else on the line. On the 240 Breaker, there were 2 big
wires on top, and on the bottom, just 2 regular A/C wires, I tried both of
them with my meter, nothing! I think I am going to call PECO now. I set my
AC meter on 500v. The meter is in the garage, I am hoping it is Peco and
not the wiring inside of the house. (Peco is our electric company). Ill keep
you posted, thanks for replying. And, there isnt any A/C to the water heater
Why are you heating , hot water , in the first place?

not know you will fear.

Yes, it is. And guess what? PECO lineman came out, and he checked the 240
line, just like I did, then went to the main. It was on an off-peak meter,
but, the timer was bad. It was on the electric companies side, and not mine
:) He replaced the meter with a digital one, and said that the other ones
are very old and do not work well. Thank you guys for helping! I think when
it got cold, it made the timer act intermittently. Well, there are 2 otehr
meters, and this happens again, i know who to call.
It is fixed now, it was the outside timer (electric companies problem), it
was just hard to troubleshoot, because I don't usually monitor the electric
line on the water heater. Thanks for the reply, the hot water is great now.
