Fuel can be supplied two ways: from disposable cylinders or through a connection to an outside propane tank.
Some people refill disposable cylinders from larger tanks using an adapter:
Non vented propane heaters can be inexpensive. Many can be mounted on a wall.
Use more than one smoke and oxygen depletion alam when using the Mr. Buddy or similar propane heaters if you plan to use the heater while you sleep.
Direct vent propane heaters use outside air for combustion and such as the Empire DV210, 10,000 BTU, or the Dickson P9000, direct vent, 5500 to 7500 BTU, are available. The Empire direct vent heater must be mounted on an outside wall and does not require the extra expense of a chimney. The Dickson requires a chimney. These heaters do not require electricity.

Rocket Stove Mass Heaters
“This could be the cleanest and most sustainable way to heat a conventional home. Some people have reported that they heat their home with nothing more than the dead branches that fall off the trees in their yard. And they burn so clean, that a lot of sneaky people are using them illegally, in cities, without detection.
When somebody first told me about rocket mass heaters, none of it made sense. The fire burns sideways? No smoke? If a conventional wood stove is 75% efficient, doesn’t that mean the most wood you could possibly save is something like 25%? How do you have a big hole right over the fire and not have the house fill with smoke? I was skeptical.
And then I saw one in action. The fire really does burn sideways. The exhaust is near room temperature – and very clean. The smoke doesn’t come back up because a huge amount of air is getting sucked into the wood hole. Neat! I sat on one that had not had a fire in it for 24 hours – it was still hot!
how it works:”
Kerosene heaters work very well. No electricity required.
Make sure that you purchase an extra wick specifically designed for the heater.
To avoid putting smoke and kerosene odor inside the house:
- Start the heater outside. Bring inside when the flame turns blue.
- Do not let the flame extinguish while inside the house.
- Adjust the wick height for a blue flame.
