I understand.

This is in no way meant to be an alternative to a thermal mass rocket heater with cob and masonry mass. It is a a good cheap shop heater.
any other concerns ? I am new at this.

thanks for the feedback.

Snow and sleet here in Ga. All day. A buddy and I made a rocket heater out of an old well tank and 4 inch channel. Worked like a champ.
