No I am not, I'm based in Georgia, USA. I am just curious about the heating crisis in the UK and wondering if suggesting the widespread use of Rocket Mass Heaters would be a viable solution.
Generally no. We don't generally have surplus biomass in appropriate quantities. We already have a pretty robust market in firewood sales and wood burning stoves. People already scrounge up pretty much all the available waste wood - pallets, tree trimmings etc... Any that ends up in the waste stream gets burned for energy, not landfilled. There isn't waste material lying around unused.
Most of our housing stock would be inappropriate or impossible for various reasons (terrace houses, rental property, inappropriate construction, flats etc...).
As a starting point, the total land area in the UK amounts to 60m acres. Our population is 67m, so less than 1 acre per person of land area.
The USA has 2430m acres and 329m people - so a bit more than 7 acres per person.
You can see that in comparison land area for growing fuel is MUCH more restricted here, in comparison. Especially when you factor in all the land used for other purposes. Typical plot sizes for a family house are around 1/3rd of an acre or less.

There inevitably will be some people who have the land area, housing, and access to fuel that would make RMH viable for them... but those are exactly the same people who are a) resource rich, and less likely to be struggling right now and b) likely to be already pursuing environmental solutions like RMH.
