I have been asked to do a workshop

Anyone have advice
The workshop I have been asked to do is here in nz.
Rocket powered outdoor bath. Mine is still far from perfect but I know what needs done to improve it.
I'm pretty good at one on one stuff but dunno bout a group situation.
It's for a local permaculture group.

Play to your strengths. You will probably be the only one in attendance who's actually built and debugged at least one of these things. Sometimes it's good if you can think of more than one way to explain a concept. Hands-on really is the way to go for RMH learning.

Where/when is the workshop? We're getting some demand in our neck of the woods (Manawatu) and may do one around summer/autumn.

Thanks the one I have been asked to do is in manawatu lol.
I am based on Taranaki.
I'm really having trouble finding a way to get building consent to install a rocket masonry heater or rmh in my home do you know anyone that has experience in this

Sorry it will probably be mid to late winter

I haven't tried to run one past a council yet. I suspect that they would treat it like a radioactive cow pat ("I'm not touching it, Trev. How about you?") and that you may need to go the BRANZ route for some certification and standards. A batch box masonry heater might far better than a plain J tube with mass, but that's just my gut.

There is/was a company in Hawkes Bay that was doing something like this and claimed to have a consentable design. I can't find any info or a link now but if I dig it up I'll send it your way.
