I have a 7500W dual-fuel generator but haven't gotten around to installing a transfer switch yet. I have a well pump and a gas boiler that I really miss when the power is out :) Radiant in-floor heat is pretty efficient (and it's nice not to have an ice-cold floor first thing in the morning), just need power for the circulation pumps and the boiler. My back up heat is a wood-burning stove - and we have lost power for several hours when the temps are -20F or so...
