A lot of homes around here have electric heat as well (I'm one of them), but still only with 100A supplies. Of course, our homes are smaller on average, with 1500 sq. ft. being considered spacious.
If I have all my storage heaters switched on, it throws a total load of about 14kW (~58 amps) on the service when the contactor closes around midnight.
Paul, please elaborate on the "contactor closing around midnight". Is that some kind of energy management program?
My house is about 3,000 SF, so my electrical requirement would be expected to be twice of yours, but we have a heat pump that does a pretty good job of keeping us warm. Resistance heating (backup) only kicks in when it gets below freezing here.
Talk about a hijack of an original thread. I have turned this thread into a completely different subject. Sorry!
