Our tradition has been to share what works. We have been using our Big Buddy portable propane heater for many years (7+), in our off grid home in NY, on the road in our camper (we full timed for 2 years), and even here in SC where the heating season is very short. The Ice Storm this winter left us powerless for a week, and the Big Buddy kept us warm!
The Big Buddy takes 1 lb. propane canisters, and although they can be stored pretty much forever, they run out quickly when it’s really cold, and they are expensive. They can be refilled from a larger bottle (20 lb grill bottle), but we find it easier to just use the 20 lb grill bottle with an adapter hose.
Very effective radiant heat, and uses 4 D batteries (I use rechargeable NIMh) for the fan. This one get’s an A+ from us for longevity, ease of use, and effectiveness.
