made many design improvements to Ianto Evans' original designs, and they have totally abandoned the Horizontal Exhaust Chimney that Ianto Evans was able to make work by
careful site-ing of house building locations, the horizontal exhaust discharge rarely works on retrofits !
I would get the PDF Copies of Rocket Mass Heaters from cobcottage.com, print as many copies as you need, it's all one price! then I would use 'the book' to fill out their
Site planning (Building) Guide and then contact Ernie and/or Erica in person, a set of plans from them will come with the opportunity to check back with them if you become stuck !
