It is probably cheaper to use electric to heat with, than propane, depending on your local electric company.
I want to better insulate one of my smaller barns or build an insulated area in one of my larger barns, as soon as I can afford it, for brooding chicks in and keeping quail in.

According to the U.S. Department of Energy, heating a home in the U.S. with a propane heating system in recent years has cost far less than heating with an electric system.
I'm about to add a heat system to my new wood shop and all my research confirmed the Department of Energy's findings; propane is less expensive to heat with than electric. I'm going to be installing a direct vent gas heater, one that draws air from outside as well as exhausting outside. I've been looking at the Modine Hot Dawg® Heaters, they seem like a good option and I'm leaning that way.
I already have propane piped into the house from a fifty gallon tank for cooking only. I heat almost 100% with wood but have a a fuel oil fired/forced air furnace for back-up on days it's not cold enough for the woodstove but to cold for no heat.
I've been thinking about upgrading the old furnace to a propane-fired unit. I've been talking to my supplier as well as others. All will rent or sell me a larger tank and do the tank install and piping to the shop and house for free if I dig the trenches.
I currently pay a little more than a dollar a gallon for propane making it the second best BTU bang for my buck right behind burning wood.
I always tell customers that electric heat is one of the cheapest to install but one of the most expensive to use.
