Ok here the dillieo… Looking for aditional Ideas and or advice :
I am in the middle (ok 1/3) of my round house build.
I really want a rocket stove
mass heater in it but no way of getting it approved!
I am going to make the most efficient rocket stove
boiler the world has ever seen! well maybe just my county anyways? Ha!
It will be self circulating, tankless/thermo mass, multi fueled & or chip feed
& it can be manual fed normally when powers not available!
I have my detailed plans
for boiler all figured out! I’ll have time next winter to build it,
I am getting close to putting in the hydronic heated basement floor, Soon! Spring is near!
I want to install a “massive” boiler heated Mass put in the center of my 36’ round floor! My ideas so far;
Dig say a 5’ deep and 10 x 10 ft hole, Would that be big enough
? or even bigger maybe? 3 storey, 3k sq ft
Insulate with ?? heavy straw cob
or Styrofoam or ? Not sure what could handle that much weight? Any suggestions?
Then maybe the bottom (if needed) and all sides with an additional insulation of 4” perlite mix that I’v read you guys talk about! Would that be good enough for a slow drain off a mass of that size, ideally @ 200 degrees?
My biggest question is what would be the best & cheapest materials to “pack” in the mass around the Pex tubing? I’m thinking crushed concrete
(not next to pex), river rocks and & sand maybe? I need typical materials form a gravel pit! My land
is mostly sand…
I do have a pond
down the hill?
