Jeff Bosch Do you have links for the things you mentioned?
The liberator has UL certification (to my knowledge useful in talking with insurance).
There is an exception in the EPA requirements for Masonary Heaters and some RMH installers have been able to use it for local inspector and insurance approval.
There is a group of Masonary Heater and RMH installers that have been working with the EPA on getting certification, but as most governmental things it is a slow process and even more so over the last couple years.
