Re: [RC] Heaters in trailers - steve lenheim - Sisu West Ranch"...just a miniature version of the furnace our house uses, which uses propane to create that heat..." Actually they are much safer than the ordinary home furnace. The ordinary home furnace, that sits in the basement in cold climates, draws air in from the basement, and burns the propane in the room then allows the combustion products to exit in the chimmney. If the chimney gets plugged, the gasses can excape into the room and you have a problem. RV furnaces, and home through the wall space heaters have a "sealed combustion chamber". This means that the compostion air is drawn from the outside, the propane is burned, and the gasses go outside. The whole thing, topologically speaking, makes sure that the fire and gases are actually outside the RV. That is, there is a sheet of steel between the fire and where you sleep. On RV furnaces, and this is the reason that new camper furnaces require electricty, the blower goes on for a timed interval before the fire starts. This makes sure that if there is a leak the propane does not go boom. In addition, a switch closes when the furnace senses that the minimum combustion air is moving, and then the fire starts. If the fire does not start, as sensed by heat, the furnace shuts down. If the furnace gets over heated, the gas shuts down. About a safe as possible.
