I bought some kind of stove that works with propane, wood or charcoal and it's supposed to be somewhat efficient. Come to think of it, I haven't seen it since we've moved. Hopefully it's in the garage somewhere.
I can see where heat would not be a big concern. But what is happening in Texas could happen to you next.
And I have been thinking about that - Folks down there (or your way) ain't ready for cold. It ain't the thing you are used to that will put you in a trick bag... I shake in my boots in a high wind - The most I have ever seen is 80mph, other than a tornado we were caught in once. You'd probably sleep right through 80mph.
But I DO know cold. If you ain't ready for cold up in here, you're just dead. End of story. Zero temps ain't nothing to sneeze at, especially where houses ain't made for it. I shudder to think of how many broken pipes there will be down there in Texas when this is done.
Of course, the REAL thing would be a wood stove. Even if you never use it but for ambiance and the odd emergency every now and then. A wood stove will get as hot as you let it. you'll never want for heat, providing you have a supply of wood. But a big propane heater, I figger, is a better investment from a prepping position, since most folks have a propane grill... And if you have a grill, you are likely to have the twenty pound tanks laying around to feed it. So I figger it fits better in what folks already have on hand.
For me it's no nevermind. I am already committed to wood, as is natural up here. But I DO have a Big Buddy and a Little Buddy for overlanding... The convenience is hard to beat, and I already have propane on board for the Coleman stove for cooking. Not the same for up in the woods, where my 4 season tent is heated by a small wood stove I pack in on a polk with the tent. I have been pleasantly comfortable in 15 below zero weather in that tent, and the stove ain't anywhere near cherry hot yet.
Our biggest concern here during hurricane season is flooding. Our attic is about 9 ft. off the ground in the garage and we put stairs in to easily access it. It has enough of a peak to have standing head room. We laid boards across to be able to sit and lay down. We moved off gulf access onto freshwater; but 9 ft. isn't very high if we get storm surge. We've been lucky...in the 30 years we've been down here, we've experienced a Cat. 4, but no storm surge. (Knock on wood).
We don't have any kind of a boat or raft...which I've been thinking about getting.
Keep an axe up in that attic... or an electric chainsaw... Getting up in there, you'd best have a way to get out... And that is going to be chopping through the gable, or through the roof itself.
I am partial to a jon boat. Flat bottom and squared ends. Nice for up in the potholes and sloughs on the river.
I will never flood where I am. Nor will forest fire get to me. If I lose it will be to heavy snow or high wind.
