Pick,

Great point. Running hours can be an issue and thanks to your math I took it one step further. Using 2.00 per gallon as the propane cost (Prices vary) the Forced Air furnace costs $.76 per hour to run vs. the cat heater at $.13 per hour. Personally I want to sleep warm and cozy, and I bet the forced air furnace will run for fewer hours per night than the cat heater to keep the same temps. Just my $.02 worth. Joan, now you have more info than you may have wanted but an informed desicion is always best.
