Rocket Mass Heater Chimney
This video shows the simplicity of my heater chimney, with the little added finishing touches I added to the TOP of the chimney. I use three "T" pipes at the top, forming an H shape which comes in handy when there are down drafts down the side of my house. The H enables the down draft to blow right on down thru the parallel sides of my chimney instead of down the full length of my chimney and into my heater.
