Thank you. We can estimate everything except the Infiltration @ 0.4 ACH volume (cu. ft.). Any idea on how to estimate this? We plan to build a well insulated, tight home. 12" in sidewalls and 20" in the attic of spray foam insulation.

Thanks.

We don't have a system designed yet, but are planning to build a home off the grid in the Ark. In the Ozarks. We overestimated somewhat the CUBIC footage as we haven't done the math to get an exact measurement. ( the top floor ceiling peaks at 18' and slopes downward to meet the floor. Bldg is three floors and approx. 40' x 44' external dimensions.

We need to heat 65,000 cubic feet over three stories. What size rocket mass heater should we build (height, width and length) should we build? The Mass Heater will be on the ground floor and the heat will distributed throughout the building through a hood attached to the duct work.

Thanks!
