Sorry for all the questions, I'm just very excited and anxious to learn more on becoming more self sufficient and getting started on this beneficial project.
Thanks in advance for the advice,

Loretta Stuber wrote:The firebricks I purchased are 4.5"×9"×1.25" model #FBP6. They came 6 to a box & are sold for pizza ovens, stoves & outdoor furnaces. I believe they came in the same box I saw on several rocket mass heater videos I've viewed online. So will these work?
Loretta Stuber wrote:I wondered about the rock. I have seen several videos that pile in the base rock layer then add the pipe but I know that hvac is very easily dented so I will be gentle. I have read about the ceramic fiber blankets & will look into building my riser as you suggested. Where do I get those two items? Online or who carries them?
