Tankless Electric Water Heater Below an Electrical Panel

tomatobeanFebruary 6, 2013

I posted this in the electrical forum, but I thought that someone over here might have some input as well...

Is there any reason why I can't/shouldn't install a tankless electric water heater directly under my electrical panel. We are in an old house and we are finishing our utility room into a laundry room and this would be the best location for current plumbing, electrical, and aesthetics. Is there anything prohibiting it in electrical codes or in some piece of common sense I am lacking. All of our electrical connections go through the attic (i.e. no connections beneath the panel.) Thanks for your input.

It's prohibited for one. And for two, to actually run an electric tankless will require most of the power that you currently have in your panel. 125-200 amps are needed. If you live in a cold climate, electrical is not really doable at all because of the incoming winter water temperature. Gas tankless is much easier to retrofit, and even it may require new gas service for the home.
