testing Rocket Mass Heater

Rocket Mass Heater: Heat for your winter garden.

I back in August  tested a small version of a rocket heater using about $20 of fireplace bricks and a metal vent pipe. you can read more about how it works here. My test works, but clearly i need to do some more math with my air intake ratio, to make this work better.

Why make it better. maybe you've heard of my winter strawberry challenge.

Rocket stoves offer some advantages over cast iron stoves:

  • 1/10 the wood needed
  • cleaner air going out (less smoke)
  • less costly to built
