Are there oil-backup HP available? I live in the Wash DC area, and it likely gets cold enough around here (for a month or so...) that i'd need some backup.
And.... how much power do these things draw? About the same as the AC units? We can bust up to $300/month in the summer on the AC
Huh. Obviously, i need to get some solid numbers and do some math.
thanks for the provocation!
