about 35 gallons (18" diameter, 28" height). Thank you for watching.

Its been Missourah in my family ever since my great great grandfather settled there. I'm the idiot pronouncing it wrong and I am having so much fun being me exactly like I am that you can be right all day and I will just continue doing what I do. Thank you for watching.

The kiln bit is an old electric commercial kiln. They are often cheap or free because the electric elements burn out and can be expensive to replace.

I assume you are asking about the air gap between the top of the barrel and the cob. That is about 5 inches per Paul's preferences. If I was trying to optimize heat capture from the hot spot up top for slow release I would build the cob mullet directly on the barrel top. Paul worries direct contact with the cob would overheat the barrel metal but I'm finding no evidence of that in other installs. If I am trying to capture that heat and direct it some place useful I like having a gap between the barrel and the cob of about an inch both top and sides to encourage thermosophoning, pulling cold air up behind the barrel and over the top and out the front, warming the air and circulating it into the room. The hot cob mullet keeps the heat from radiating up into the ceiling, then continues to heat and circulate warm air after the fire is gone and the barrel is cold.

@@UncleMud . Thanks for sharing about the air gaps or lack thereof. Can you point me towards some of the builds that use the cob directly on the barrel lid? Many builds seem to rely on a firebricks and ceramic fibers for the ceilings of bells, but those materials are relatively expensive. Barrels are a low cost bell , so if they can be made heat retaining and presentable with cob, that would be great. I am interested in using leave in place forms to cast a "cob" bell around and over a steel barrel. This would be kind of like a Paul's pebble bench, except even cheaper . It would be harder to harder to disassemble for repair. Creating a cast earth plug to cover the lid of the barrel might be enough to address this.

It is flat. Thank you for watching.

I like that. Thank you for watching.

Hello. to you too.

If it is cold out the warm air in the house will cause an automatic draft and the heater starts quite easily. If it is cool outside (say 50 degrees F) I will open the cleanout/priming port at the base of the chimney and light a wax fire starter there then close the port and let the heat create a good draft before lighting the fire in the heater. Thank you for watching.

Thanks for sharing the love from Bangladesh!

It is a pity. I also work with Gamera.eu who produces a great product and ships worldwide. Tell them Uncle Mud sent you. Thank you for watching.

The Baby Liberator is sadly no longer in production. If anyone wants to buy my demo unit email me at info@unclemud.com Fired twice for a demo $1200 including shipping. The full sized Liberator is the only one that is UL listed and EPA approved for code install in a regular house. Be aware the big liberator is still a small heater (around 30k BTU per hour) it works well with a mass bench. Gamera.eu produces really great heaters in 3 sizes small to big. They are pollution and safety certified in the EU, but they are not UL listed in the USA.

You're welcome

Thank you for the feedback. That is the way I talk, but I am learning better editing.

Yes. We have tested that. The temperature at the bottom of the riser is hundreds of degrees hotter than it is at the top. We have tested the bell model and found the stratification makes the top way too hot and the bottom way too cold.

pyroceramic glass. Thank you for watching.

The name Wofati stove refers to it being in an underground building called a Wofati. Sorry for the confusion. The stove itself would be a "double shoebox rocket stove" referring to the shape and configuration that encourages a complete burn. The pyroceramic glass top lets you cook on it. thank you for watching.

You could. Absolutely. I wouldn't just out of preference. Concrete, sand and bricks, pretty stones. I do know that when I want to reconfigure the room the cob is going to be a bit of a hassle to remove, but I can oak it and reuse it. Concrete would be a super pain to remove and it would not be reusable.

Thank you for asking. The hot chimney goes right through the middle of the whole mass bench to warm it.

@ so it’s essentially a kink in the chimney that just so happens to warm the mound you put on top of it too on its way out the chimney at the end? I’m planning on putting a long one made from cinder blocks under a hydroponic setup to keep my veggies from freezing during the 2-3 days of freezing we have in SE TX. So basically line up the cinder blocks, seal cracks with concrete and put the chimney at the other end voila rocket mass heater? Thanks for your content. It’s helpful.

The barrel very quickly gets hot enough to make steam when you splash water on it. No stones necessary.

The glass door is just a piece of pyroceramic glass cut to the size of the steel cleanout door with a small notch to hold a wire wrap with a loop in it for a handle to make it easy to open and close. Thank you for watching.

drop me a note at info@unclemud.com and I will try to connect you with the owners.

Very much. I'm using it right now. I've built several greenhouse rockets. Greenhouses require a lot of heat compared to a similar sized house. The larger Gamera or an even bigger CottageRocket would be a better fit for a greenhouse. Drop me an email at info@unclemud.com if you are interested in a design consultation.

I would not trust an electric blower. Wood exhaust tends to wreck those pretty quick. With a mass battery/heat exchanger the exhaust temp tends to be pretty cool so it might work with a pellet heater wall exhaust but I wouldn't chance it. Solid fuel heating appliances should always be connected to their own UL listed double wall insulated stainless steel chimney that goes all the way up to at least two feet above the highest ridge line of the house. Thank you for watching.

No glue, no finishes, just kiln dried hardwood cutoff from the manufacture of hardwood flooring. Thank you for assking.

Thanks for watching!

A primer port is a lovely thing. Thank you for watching.
