Re: Natural Homes: techniques, solutions and beautiful images
Yes. The brick masonry heaters/Russian heaters that I've experienced are ones with the horizontal baffles and they work very well.
The interesting correlation between the very fine ash from high efficiency, masonry wood-fueled heaters and the use of volcanic ash in "Roman" concrete is the importance of the use of ash as a soil nutrient for growing healthier crops. Volcanic and Wood ashes both make for more nutrient dense vegetation when compared to the many nutrient depleted soils now in use. Meaning that some very natural materials available to humanity have been lost to the fevered pace of industrialization and modernity.
I've heard of and seen rocket mass heater designs but have never experienced one. I'll look for one when I'm around my building friends to see and feel what it's like. The principles of the design look much like those of the Northern European Heaters.
