Hi All ; Got the bright idea to check some mass temps this morning, 12+ hrs after the last fire.
Outside temps this morning did not get as cold as expected 36 F, nor did the 7" of snow fall...
greenhouse / studio temp this morning at 9 am was 51 F taken at chest high across the room from the mass.
external temp of brick outside of burn tunnel 108 F
temp outside of feed tube 101 F
Cob at mid way on barrel 61.0 F
Top of manifold / transition area 107 F
side of mass near core unit 103.6
Top of mass next to vertical pipe exit 83.7 F
center top of mass 72.1 F
Far end of top of mass 66.9 F
As you can see large mass equals a long hold time on temperatures. I will try to post with more readings on a below zero morning.
