Back-up generator selection questions
This may be the wrong place to ask, but I'm betting some of the great minds on this site can help. How does one figure out what size generator to purchase as a back-up for a whole house? Go room to room and add up all outlets and appliances and then figure some percentage of that (since I never run everything at once)? I'd prefer propane, but I would also like to consider diesel as fuel. And are there brands you specifically recommend?
