Put in a propane stove. I removed electric stove and water heater when I bought the house and piped it myself with the yellow gas pipe. Bought online with all the fittings from a place in Florida. I also removed the central furnace and put wall gas heaters in rooms saved a ton. Yes, you can put a smaller one in a bedroom as long as the air flow volume through the room is sufficient and it has an auto off low O2, tip over on it and put a CO2 alarm in the room
My cabin up north has a gas stove and fridge. Can't recommend strongly enough to go that route. Up north I use both smaller size tanks and they run good with the large RV tanks especially easy to move around. Use an automatic switch over and you will be good
