A month or two? Run a couple of electric construction heaters, may be able to use stove/dryer circuits or do some temp plugs...
Watch out for amperage. Can't recommend running more than 10kw or so (considering there are other loads) on a 100 amp service. think they're 5kw each.
Expect to have high energy costs, but lower than trying to put in some temporary b-vent.
