Great job, but if anyone is new to all of this.... all of these little "Rocket stove nuances" and details aren't necessary. For example, little cut bricks making a V in the firebox and little angle cuts in the riser chimney to make "the vortex", or the insulation around the riser. The secondary air isn't even necessary. All of these little things add only 5%. If you are of limited skill and budget, simply make a firebrick box for the wood with a ceiling of angle irons, connected to a 3 foot "chimney riser" made of firebrick with a verye thin layer of Rutland refractory cement, and build a brick box around it all with a good 10 foot or longer chimney connected to the top of the red brick box. (Firebrick not needed for the outer box. Mortar of 3 sand, to 1 clay, to 1 lime works well. For air,It's easiest to build another box below the wood and have the air come up through a home made grate of cut rebar the wood lays on.

Would love to see this in action. Also, temperature of what is coming out of the chimney.

Wow - that is a nice looking build! Well done!

Thank you!

Why insulate the firebox? Why insulate the riser? Why insulate the brick, thermal mass, when it's that part you want to heat up? A regular brick is "fired" (made) at 1,800 degrees F or hotter. It can take the 600 to 900 degrees of that part of the stove.

i love the way you guys used brick to make it its so beautifull i will make it for mine this way

Very nice job, thanks for sharing 👍

Nice clean design. Better than all the rest I have seen

That is an excellent job, thanks for the video of it, the only thing I would have done differently is to install a oven in it at about 1.2 metres high if it was possible, then you could use it to cook as well, I have not seen one made like this before, the chimney is normally buries in the floor area and then Cobb is used around it to gain a mass that then heats up, your using what looks like refractory bricks to hold the heat and I would imagine it does the same sort of thing. I have a normal style wood burner 15KW inset but I have yet to build the brick surround around it, this summer I used refractory bricks and just laid then on top of one another around the fire to see how well it holds the heat compared to a normal woodburner which is freestanding. The difference is enormous, the lounge is around 23º when we wake up in the morning, Normally it would be about 17º , if I wake up in the night I put one more log on the fire and it's still very hot in the morning and you can just put logs on straight away. If I don't use a log in the night is still very warm and I just need to put some kindling on to restart it. It really keeps it warm. My chimney is 200mm diameter stainless steel. I am amazed how good the refractory bricks are at changing the way the fire holds the heat in both the woodburner and the bricks around it. Next spring I will be building the fire surround completely in Refractory Fire/kiln bricks and filling any spaces behind the bricks and woodburner ( as its in a corner ) with fire cement and more broken firebrick, This way there will be no hollow spaces around the Wood burner, I will just leave a tiny amount of space to allow the expansion of the woodburner so the new bricks do not crack. I think the more material that you can build into the corner of the room where the fire is and the hollow spaces that you fill will create much more mass which will heat up and slowly give off heat, I am then hoping that I do not need to burn so much wood, I can just light a good fire and let the mass heat up and then allow the fire to die down and feel the radiant heat come into the room. I personally do not like the look of the normal style heaters that are made with a 45 gallon oil drum and lots of pipes and cobb to cover it, it sort of looks unfinished whereas yours looks nice and tidy. Thank you for the video, great work.

Good work! What is the reason why the bell in the top has double skin with insulation in between?

@batchrocketmassheaterportu264

4 жыл бұрын

The main purpose is to protect the outer layer from cracking. The inner layer expands and the soft insulation takes the expansion. It also makes for a more homogenous distribution of the heat

wonderful video! thank you for sharing! is the bell taller than usual?? would that effect your ability to add a bench?

The bell is as small as is possible within the specification guidelines provided by Peter vd Berg on his website. This to accommodate an as large as possible heated bench.

Thanks for the video. It’s such a nice build. I am curious, why did you put that white insulating blanket along the entire brick? I would suppose it would prevent the outside bricks from absorbing as much heat. Just wondering.

@batchrocketmassheaterportu264

4 жыл бұрын

Thanks Scott. The blanket sits between two layers of bricks. The inner layer will expand due to the sudden extreme rise in temperatures. The blanket absorbs the expansion without affecting the outer layer plus that it slows down the extreme heat to the outer layer. So its a kind of double protection.

I think that insulation between the layers of bricks is a big mistake that greatly reduces the efficiency of the stove. In this way, even if the outer layer of bricks is protected from intense heat, most of the thermal energy is lost on the chimney ... The point is to heat the house with as little fuel as possible, that's why we call it an ecological stove ... right? ?? Complete combustion = minimum pollution + efficiency, ie good heating with minimum fuel consumption ... The stove made by you heats more outside than in the house .... You better have made it completely from refractory brick and thus, you would be heated the house with a third of the fuel you burn unnecessarily extra ... Even with normal brick, you could make the fire softer so that the brick doesn't crack because you really don't need extreme heat ... it's just a stove to heat the house and not to melt steel ... Also, the bell brick was good to be built in width, so that the wall is thicker and therefore have a higher thermal mass ... The insulation is made only at the hearth and at vertical fire tube, to protect the normal brick ... Anyway in Portugal you don't even need an efficient stove for how hot the winter is there ... No offense, it's just my opinion ... Regards.

Radiation heat higher than a human body is for my opinion relative useless. We do not want to heat the air with this kind of stove. Sorry for my bad english.@@vicoltitus9753

Hi, All the bricks are the same Firebricks with different sizes, or the core and the riser you are using different materials?

We use the same firebricks from the same manufacturer because they are not that expensive here but its really not necessary to use firebricks all over. I would say the only part of the bell that needs firebricks is the part above the riser directly touching the hot gasses. The rest can be normal bricks.

The heat riser opens up into a relatively large space, called the bell, where the gasses slow down to a halt giving the gasses the chance to stratify, hot gasses go to the top and least hot gasses go to the bottom ensuring that only those gasses leave the system.

Missed out on how you capped the bell.

Hi Thomas. We use a number of steel T-profile bars supporting a layer of firebricks, then a layer of Superwool, followed by another layer of bricks. The same process can be seen in Peter van den Berg's video at around 2:50. kzread.info/dash/bejne/i6NpzqSCk9vFaLg.html

Surprisingly, just to be on the level, I contacted my insurance company about my plans and they were cool with the idea as long as my local building inspector would sign off on it. Contacted him and described what I wanted to do. He didn't seem at all vexed with the unusual design, just so long as it was built with refractory materials. He also seemed to insist on calling it a "fireplace", which I think was his tounge in cheek way of giving me the nod without opening a big can of worms. Just thought I'd share.

By adding the insulation blanket on the inside is this preventing the heat penetrating beyond it and radiating through the bricks and heating the room ?

good point - they probably don't want the exhaust to cool off too much up above so that down near the floor it is much cool to condense the exhaust as a negative pressure.

Thank you for your comment. There is no way to inspect the inside of the bell from the top and I don't think its necessary. Buildup of ash happens in the bottom and mainly in points where the direction of airflow changes , in bends, going into the bench and fluepipe exit. This we can all reach. We dont have any plans as of jet.

the concept is the rocket gets above 1200 F. so there is a clean burn with no pollution and then the extra heat is absorbed by all the thermal mass around the "riser tube" (that is the rocket).
