Here is a link you can try. It is Canadian, but hey...demand is demand for a quick reference.

That's a neat calculator. Just for fun I punched in the numbers for a known house and it came back with a demand of 21kW. (Not really relevant as I'm in Europe, but hey demand is demand [Linked Image] ) What kind of service would you use for this in US/Canada?

We'd use a minimum 100 amp service for a 21 Kw (88 amp)house demand load. (Canada)
