Jon S. ; This is not a problem, there are a few people that would like to see all Non-
Rocket Mass Heaters hidden away somewhere else where they would not have to
admit That there actually is more than one way to make an efficient
Wood heater. Sometimes i manage to make a few of them mad at me, but I have always been
saved byour "Play Nice " Rule !
You have just shown that a Masonry Heater can be made ( with
enough help) in the same time it takes to make a
Rocket Mass Heater ! Please continue to show us what
you are doing with both types ! The more knowledgeable voices the better ! Big AL !
