NSW Australia Rocket mass heater. 

I've never seen more confused commenters, but some have a point..... if the video maker was going to do all that showing every single moment for 2 days, 60 seconds of narration explaining a thing or two is not a lot to ask. Here you go, ... the gasses hit the top of the barrel. The gasses exit the barrel and move in all directions, some filling the "hollow" bench with warm air to heat it up and some gasses filling the brick "bell," .....(to our right of the heater with warm air.) The long metal (final) chimney is placed strategically collecting gasses at the bottom to allow gasses to escape the building, hopefully, after warm gasses have moved past most bricks to warm the brick so it can radiate heat for several hours after the fire that heats the upside barrel, is extinguished. The rocket mass heater is made of ceramic fiberboard sold on Amazon.

narration better than repetitive music

Hey, I'm a learner here. And though I have been studying up on these things, I found this really hard to follow and pick up on what was going on, even when slowing down the playback speed. A few words or captions and a better camera angle or close up might help a LOt!

Did you get it passed in aus? Im looking at how to do that in tassy. Also, how long does it hold the heat for?? Thanks for sharing

Гарна робота🇺🇦☺️👍

Thank for useful video. May I ask: Are you using high density fire bricks for bench/bell or regular building bricks? The large mass of bench back looked to be cob filled, does that sufficiently absorb heat from the small surface area it is in contact with hot gasses in bench or does it have some porting/channeling to help this? Sorry for long message.

What method would you use to eliminate the MASS part of the stove. Do not have room for that size of mass. What would you recommend.

Did this method make you save the amount of firewood you usually used, or did it increase?

Why on earth would you block the window with a row of cinder block? Could have thought this through better.

Would love to see a diagram of how the fire exhaust stream enters and exits the bench. I didn't see a run of pipe, so it looks like the bench is a stratification chamber. However, the entry to the bench looks lower than to the masonry bell to the right of the stove (8:40), which is also where the chimney flue is, so wouldn't most of the exhaust stream bypass the bench chamber?

How is it working for you? Does the bench get hot?

I would like to see how those 45 gallon drums are after a few years of being exposed to such heat Rusted burn through possibly But what really puzzles me is the fact that this chimney did not go through the slab to the left and there was no fill put in there to contain the heat

Greets from Finland. Rocket mass heater is OK, but as a ignorant northern dweller I must ask where in Australia you do need heating? According to my TV AUS is jungle or hot desert :)

Why is the riser necessary? Why can't you go straight into the Mass material then flue?

How do you get this passed on building regulations? Keen to build one on a new build house.

but great otherwise

I like the look of the bench but it doesn't do anything

Instead of music say what is done

Not useful as a teaching tool. All this says is: ‘Look what we did!’ This is why time lapse videos are generally a waste of time. Without explanations, tips, warnings, options…why bother?
