I was about to kick myself. Bought a whole house natural gas generator for 8. Around 4500 sq ftNeed to recheck....under 40...and getting closer to 30.
Of course for all the knob and tube guys out there...I can understand if you are still running very inefficient homes!
Edit: Did you include a NG run out to a house sitting 1/2 mile off the road with no NG lines around? Suburbanite!
Edit: K&T is there so Hatin' can get edumacated
