What people are saying about it…
…It covers very many details which appeared as questions during my two builds and I have not seen addressed anywhere else, covering tools, materials, design, build and finishing. It has excellent quality video and audio. It is a composite of footage shot on site during the build together with a separetely shot and well thought out interview with Erica and Ernie (with excellent quality audio). Inside the DVD case there is a printed page with a list of tools and materials used in the build … superb attention to detail…
I just received my DVD today! I was so excited!!!
I opened it immediately and popped it into my laptop, and grabbed a glass of wine to watch and learn!
… and … WOW! You guys did an absolutely fantastic job! Definitely exceeded my expectations! This is exactly what i was HOPING you would produce! Pure usefulness! (an especially big kudos to your video editor!)
Thank you! THANK YOU! … for all your months/years of effort producing this DVD for us interested amateurs/dreamers! (and I’m a mechanical design engineer, and I approve). You’ve done a really fantastic job, I really love your DVD! Please share my positive feedback with your entire team!
Inspirational! (I’ll be watching this video at least 100 more times, no doubt, as I build my own rocket stove heater!)
A thousand Thank Yous! I feel blessed and grateful to be learning from your experience!
Watched the new RMH DVD from Village Video! It details the process of Ernie and Erica building this (now famous) installation over a hardwood floor. This is the most comprehensive, informative source I’ve seen yet! I now feel much more confident moving forward with my project. Thank you, Calen Kennett for producing this masterpiece. It will help many people realize their dreams of building a sustainable heating source for their homes. I recommend this DVD to anyone who is interested in this technology.
This DVD IS AWESOME. You did a really great job on it. I held a viewing with some friends, and it was strikingly engaging! I was worried it’d be slow, but the editing is great! Visuals were rad, pertinent, and well timed. And Erica is an excellent speaker. I’m sure you’re aware 😉
