20 lb of LP gives about 400,000 BTU of energy. What's this fuel cost? How efficient are these LP heaters?

How much for 120 kwh of elec. energy in your area? Here it's about $18.

Refill around here on 20lb LP is around $17-20 depending on where you go.. not sure about efficiency ratings on them to be honest though. I use one of these in a shed I have on my property, but never really paid much attention to efficiency on it as I only keep the t-stat set around 45*F because I store my diesel tractor in it along with a few other things. I was thinking more along the lines of the portability factor. Granted if the OP is going to basically set it and leave it electric would be fine, but if it get's transported a lot to different area's, you may not always have immediate or feasible access to electric.

Default Yup

The propane is the way to go if your looking for quick heat, and have really cold outside temps. The drawback is gettin the propane filled and you still need some sort of electric ac/dc for a fan to push the air.
Another easy way is to look into the RV A/C heat pumps that run on just electricity. Simple to maintain, and you get a/c. Drawback is they don't heat fast, and don't heat in anything below about 20 degrees, depending on the unit.
This is only a 200 sq ft unit...tiny for any heat you really need, and not worth radiant $$.
Hope this helps.

An average US house takes 6 BTU/(Heating Degree Days x sf) so for CINCINNATI/NORTHERN KY INTERNATIONAL, KY, US (84.67W,39.04N) having 952 HDD for January, this gives you 6 x 952 x 192 = ~ 1 million BTU. At $18 for 400,000 BTU/120 kwh this would be $49 for January.

A tight house might only cost $20.

Ya' oughta' run some tests or get the Manual J calculator off the Web or ask the log cabin people for their guesstimate.
