Load sharing to reduce total load??

[jmanson]

I'm doing a renovation to an exsiting 2500 sq ft house with gas heat (and water). It has an existing 100 amp service that would be difficult to upgrade to 200 amp, although it could be done.

I have an electric hot tub (35 amps?), and I'd like to add an attached workshop with gas heat. Might want to add a suite as well, but I'd probably go with a gas stove. Looks like I can stay under 100 amps if I do some creative load sharing - say putting in a device which doesn't allow the electric range and hot tub to come one at the same time. Are these devices allowed under the code (BC), and do I get to reduce the demand by the lower load of the two in calculating service size??

I would update that 100 amp service to a 200 amp in that big a house.
