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.
