We used the MR BUDDY heaters back in the tent camping days and they worked fine for us but tents are vented to the outside pretty good..
I still have the Mr Buddy single LP canister model here for my backup heat in my OFF-ROAD POPUP setup. I have a top shelf that is situated just under the ceiling mounted FANTASTIC Fan which I open up a tad to vent out the generated fumes as well as probably alot of heat. I also have to open a flap on the other side of the tent trailer to replenish the burned up oxygen inside the trailer as well.
About the only thing we do safety wise is not ever leave it on when we are asleep. We use electric bed covers running off our INVERTER SETUP for sleeping.
About the only safe propane setup that I would sleep with is the Vented CAT PROPANE heater.
We hate our propane furnace big time. It is way too much heat for our OFF-ROAD TRAILER setup (runs us out) and it is also has a very LOUD 12VDC fan setup. This fan to me sounds like sitting in the back row seats of MD80 aircraft. a Real loud GRRRRRR sound. Wakes us up everytime it kicks in. The 12VDC fan is also a big battery drain item (6-8AMps)
We are thinking about yanking out the Propane fired furnace and installing a hydronic water heater system using the spot the old furnace was located for the heat register.
This concept:
The heat register install might look like this google search install.. This also supports hot water baseboard heat registers..
Have no idea if this concept saves any energy cost as BTUs are BTUs whether it comes from propane gas or hot water heated with propane gas or electric. It would be VERY QUIET in operation for sure...
This could be supplemented with the CAT PROPANE heater setup for us if needed.
Always changing something here trying to conserve battery energy when camping off the power grid...
