Hi Brody, Ist, Never, Never, Never burn pine in a wood stove. Watch for nails while cutting pallets with a skill saw.
I understand the visceral need for wood. At the same time alternative heating and supplemental heating are closely related. An oil radiant heater, electric ceramic forced air heater, inferred heater, etc. It's possible to get these for around $50.00. They will extend the life of propane. My wife and I point the heaters at ourselves. The bedrooms are cooler, but you said you like that. We have gone from 5 to 3 fill-ups in a cold year. 4 to 2 in a warm year. The cost savings for us is one fill up of propane. for cold years, and 1 1/2 fillups in a warm year.
So, wood, electric, oil, candle in small room, what other heat source could one supplement propane with? Might be worth a day to look into it.
Stay warm, stay dry.
