If we want the technology to spread , and Paul's stated goal is to transform the way the world's houses are heated, then no. Placing administrative barriers between learning and doing is going to create less people able to do and learn.
If we want people to experiment, refine, and explore new directions in the technology, no. The gatekeepers of technology always limit innovation.
Any sort of certification is going to make it difficult for DIY's to get the systems approved by the code enforcers and insurance inspectors.
Finally, we must read the zeitgeist and tack if we want to sail the mainstream. We want
RMH to be popular, right? The organizations you listed are unpopular and going to become more so- if they even continue to exist. This tech
should be billed as a ancient one reborn, free to all mankind to be used, a handmade brick in the wall of independent existence, not as something that some department recognizes.
The solution to whatever problems exist with
RMH and masonry stoves is not more government, administration, or other rigmarole.
