Re:My recommendations (Score 1)

I have a 13 kW for my house and home server room, and it runs everything we own, except the stove and electric dryer shouldn't be on at the same time as the HVAC compressor cycles ;P With every light, fridge, TV, PC and ceiling fan in the house on, ceiling fan, and HVAC running, we draw ~7 kW. The extra 'over size' handles the compressor startups and surges. It draws ~100 CF an hour at max, and I ran it for 4 days w/ no issues when Ike came through. Can't recommend a whole house Nat Gas system w/ an automatic transfer switch highly enough. Runs at a pure 60 Hz, keeps my UPSs happy, and auto-runs every week for 7 minutes. $5-7K fully installed usually, saves its own cost in fuel.
