[Stoves] Water heating fuel efficiency formula

[Jonathan P Gill]

Lanny,

I concur. You will like my new PDF.  

I remembered your stove from earlier posts, but not it's name nor it's creator. Hats off to you.  We think alike. I do use a bit of draft to suck in clean secondary air, but not to evacuate combustion gases from the closed kettle.

Cheers,

Jock

Extract CO2 from the atmosphere!

The main purpose is to exhaust the fumes up out of the cooking space. Cook space air pollution can be a problem outside as well as inside.
