RMH Ponttouuni efficent clean high capacity batch box wood stoves by hastyheat
This Finnish/Nordic style Pönttöuuni RMH wood stove contains a huge thermal mass of stone within the bell heat exchanger that is heated by the clean burning rapid conflagration combustion chamber flue gasses to as high as 700f storing over 50 kWh of heat that is slowly released over many hours. Eliminating the need to try and smolder a fire all night long. In contrast this Finnish/Nordic style rocket mass heater wood stove is burned with a quick intense clean burning fire that is safely burned out before bed, allowing the thermal mass to do the heating overnight. Retaining the majority of the heat from the flue gasses in the thermal mass reduces and lowers the exhaust temperature to 100-200f. This keeps the heat energy of your firewood in your home where you want it without the high emissions of unburnt smoke wood gasses that would otherwise go up the chimney and pollute the neighborhood.
Able to heat a 1100sq ft home on one bucket or about 30# of wood per day at below -15f temperatures!

This prototype shippable Pönttöuuni I built has blown me away with its performance. I have been testing it all winter north of Helsinki at -25. By winter 2024 we will be manufacturing them to ship from both Finland and USA covering the needs of both hemispheres...
Most notably its operation is to just pack the firebox full of logs, open the air vents and chimney damper 100%, ignite and walk away. No tending no stoking. Let it burn hot, clean, and fast. When it burns most of the coals up shut the damper and let it radiate from the stone for hours overnight. Rinse and repeat in the morning. In extreme cold maybe enjoy a mid day fire 🔥...
Air quality in the house is better without constant stoking and fire door opening. Burning the fire hot and fast you make less pollution and get twice the heat from the same kg of firewood. No unattended overnight smoldering fire hazards. Just one bucket of split firewood a day keeps my family cozy.
