Erica and Ernie Wisner are coming to NZ in February
The Wisner`s are experts on building RMH`s aka Rocket Mass Heaters.
RMH`s are possibly the most efficient and clean burning wood fired heaters in the world.
They are constructed from cheap, local, recycled and natural materials, and can be built by anyone with basic skills and tools.
The Wisners have been involved in the construction of over 600 RMH`s in America and have got them up to “permit standard ” on suspended wooden floors.
At the moment Grant Steven in Moerewa and Graeme North in Warkworth have committed themselves to holding RMH workshops but the Wisner`s are stopping in NZ on their way to Australia and have said they could come back to NZ after they have finished their Australian Tour
The workshop in Moerewa will probably be in the third week of February but we do not have a definite date yet.
There will be a very intensive and advanced RMH workshop with the Wisners that will be over several days but alongside this will be introductory seminars probably run at Tuna Cafe
