i generally run it with two batches twice a day if its very cold and then once a day when its not so cold. but its Mediterranean climate here so not really that cold
For the first fires, when you have finished your stove, how much load of wood do you put? the same load as you put normally or at the first times you put a lesser load to leave the stove get dry gently? Thanks.
Perhaps leaving the inlet completely open is not so efficient. Burns your wood too quickly…unable to heat the surrounding brick. Just a thought. Blessings
The idea of a rocket heater is to burn hot and intense and then the exhaust gases heat the mass. Not the fire itself. Rather the opposite actually since the core is isolated in most builds.
I certainly do it differently, and for the following reasons: firewood consists of many combustible compounds in a sponge of charcoal. When you heat all the wood at once, you can never feed the fire enough oxygen to burn all these compounds that are exiting the wood as smoke. So you want to build a fire that gradually heats the wood to give limited amounds of gases, and once degassed you have the bonus of burning the remaing charcoal. This method keeps the chimney almost free of soot, prevents grey ashes to swirl and leave through the chimney as fine and hazardous dust, and also is much more economical. It’s the preferred method both in The Alps and Scandinavia, and gaining ground elsewhere.
Thanks for putting this up. I must ask; what makes this a *rocket* mass heater? I'm familiar with the concept, so I'm wondering where the "rockety" aspect is in this build? It does not seem to get the typical super oxygenation to the fire to get the extreme heat - or what am I missing? Again, thank you.
It very much is a rocket stove it creates a double vortex burn and is the most efficient rocket stove or wood stove in general. Even more so than a natural gas stove. This thing puts out a ton of btu's. The heat riser (stove pipe) has temps of over 2000 degrees F. This is why they no longer recommend using a steel heat riser (stove pipe) use only fire brick or ceramic fiber. The idea with a batch box is to burn it's load as fast and hot as possible and load your thermal mass with as much heat as you can. Burn time for a typical load is 45 min. These things are incredible!.
the secondary air channel has replaced the p channel as far as i remember Peter saying. it pops out just infront of the small opening before small opening at the back
Great video. Orbiting giggling toddler is hilarious.
thanks
That’s nice!
How many times a day do you have to run a batch of wood, how much thermal mass do you have as a battery, looks awesome

Boa noite ... Uma carga de lenha durou quantas horas ? 🇧🇷🇧🇷
Hola quedo genial y con banco!!!!. Porque no tiene el umbral el canal de piso, es por algo en particular ?
no es por nada mas que con el fuego se oxida y lo tengo que cambiar cada año, ese año aun no lo habia vuelto a poner
How do you attach the door to the brick box?
Where can I find plans? I clicked through to your website, but it's a blank page.
Mandala, using a go-pro on your forehead to make the video, it seems to be convenient for you, but in my side it is a vomiting making machine.

what makes a rocket heater a rocket heater is the noise...listen😉

So you have to keep filling it every 45 minutes fir how long? 3-5 times then the heat mass should be good for the day or night?
@@maverickgood5204 Only once or twice a day, unless it's extremely cold out.
i'm building one right now...you have no p channel..correct? just secondary air at the bottom? and where does that secondary air pop out? thanks
