My neighbor and I were talking the other day about the frozen pipes in
his shop. This is because he didn't insulate enough the pipes in the
walls and because it's only heated when he is working in it on the
weekends. Now, with the walls covered and with benches permanently
mounted he doesn't even want to consider trying to add more
insulation. As it is just repairing the split pipes will take him at
least 30 hours. He could drain the pipes but he forgot just once hence
the split pipes. He could also leave the water on but that would mean
pumping a lot of water out of the well. So I opened my big mouth and
suggested running a low voltage through the pipes to warm them up.

Let me see if I have this straight.

Electrical code requires metal water pipes to be bonded to the grounding
electrode of the building's electrical system, to ensure that the water piping
is at zero potential with respect to ground and thus eliminate the possibility
of electric shock from touching a water pipe.

And you're proposing deliberately placing a voltage on those pipes.


um... have you ever heard of electrical isolation or transformers?

Not relevant. Run that scheme past the local electrical inspector, and see how
he likes it.
