Rocket Mass Heater builders in Ireland?

Hi everyone, I recently saw a video on Youtube by Robert Murray Smith explaining the 2022 EU (and UK) change to manufacturing and installing heating systems in homes. The video is his episode 1745 Rocket Stoves and the Law.(Here's a link:  https://www.youtube.com/watch?v=v7RicMVWqQo)

Basically, since 2022 it is illegal to install an unregistered and unlicensed heating system in your own home. RMHs need to be installed by licensed and regulated RMH builders who have passed EU/UK standards. I have found on the Permies site lists of registered and licensed RMH builders in continental Europe and the US, but I can't find anyone in Ireland (or even the UK) yet.

Personally, I think an RMH building business would be a gold mine for any experienced people (alas, I'm not one of them). Does anyone know of anyone in Ireland who is planning to start an RMH company, or who might be interested in doing so?

Yours in hope and eager expectation,

Matthew.

When trying to talk with building inspectors and insurance companies, this stove is called a masonry heater.

Here is one:

 Custom masonry stoves, kachelofen, grundofen, pizza ovens, bread ovens, masonry cookstoves, ceramic stoves, tile stoves and other masonry heaters in the UK and the rest of Europe.

Yes, I am aware of Masonry heaters. But they typically use 50% of the wood that traditional wood burners use, whereas RMHs use as little as 20% of the wood. RMHs are even more environmentally friendly, if the claims are true.

From the site that Anne linked to above

By masonry heaters we mean any individually designed and hand built heat appliance with system of masonry flue ways that stores heat in its mass and warms the living space by radiant heating for 12-24 hours after burning one batch of fuel.

By that definition, a rocket mass heater is a masonry heater. If you call it a masonry heater, a whole load of problems just disappear.

I had a little look at the video (RMH from 9:50 so you don't have to watch the whole lot!) and dug out some legislation (English version see p43: Solid fuel heating systems) and it's not quite as clear cut as Robert Murray Smith makes it sound. I don't think you need a registered installer or device, but it does need to burn compliant fuel (dry wood) and meet efficiency standards. That second point is the one that will be difficult to prove with a one off design. I suspect that there ought to be enough information about, that if you follow a known design (such as Erica and Ernie Wisners') or one of Matt walker's designs) the information has been gathered, and should be clear cut (can be >100% efficient because the standards start with 25% going straight up the chimney!)
There may be more information in the HETAS guide -  I haven't looked into that yet.
