How To Make A Concrete And Perlite Rocket Stove 4.5

In this video I re-make my DIY concrete rocket stove with the addition of perlite. Many of the improvements to the stove design were suggested via viewer comments. It's hotter and lighter and will burn cleaner.

The perlite adds insulation to the concrete body of the rocket stove, reducing the thermal mass. This makes the stove much more efficient and it should boil water, my primary use for the it, more quickly. An added benefit of using the perlite will be the reduction of the weight of the stove.

Next week I'll be adding a J-tube to the stove, bringing the design closer to the a true rocket stove. Then I'll test the stove's performance with and without the J-tube.

great work. just a suggestion to add more strength to the concrete after drying. water the whole stove twice a day for the next 3 or 5 days. if it rains, let it rain. trust me, that will prolong life and prevent cracks. this is a proven practice in the area Saudi Arabia where i live. thanks again for sharing. i may do this for my desert camping😃

Adam Sandler goes off-grid.

Great video. I want to have a go of this but imbed a copper water coil within the concrete to use as a pool water heater.

Reckon that’ll work?

Just a thought... Instead of rebar, maybe drop in anchors... That way you can use different sized bolts to adjust the height

This is a great channel. My dad would love to watch this channel.

Great video! FYI the standard cure period for maximum strength concrete is 28 days. Although it continues to harden forever it achieves the majority its strength in 28 days. Also, keeping the concrete moist during the curing period is a good thing. Curing is a chemical process that involves the growth of crystalline structures that is aided by moisture.

I am so glad I found you . I have enjoyed watching your second build on this little stove . I myself was thinking about no stick spray from the kitchen. I look forward to more videos. Thanks for sharing

I love this...but a helpful hint from a former concrete contractor...curing doesn't require protection from moisture (i.e. trash can lid) but protection from drying too quickly, so actually the lid is keeping the sunlight away while you allow it to cure...excellent be afraid to grab the garden hose and soak it daily for a few days or even weeks for a stronger oven ....i hope to follow your video and make my rocket stove that i can have on my semi ...thanks for the awesome vid .. a trucker from Wisconsin

You could try some air restriction at the incoming opening for when the fire gets really going. This will calm the burn while maintaining temp. and conserving fuel.

Your video popped up after watching a similar video, never heard of such a stove, thank you for sharing and I appreciated how you used other viewers ideas to improve your design and showing us while doing so. Thank you...

Wow! this is the best rocket stove design that I ever have seen, great job, love the design plan you made, if ok, I like to make one for myself, because you made it so simple. Thank you for sharing. I really enjoy watching your video.

Dude! Just throw a piece of 6" single wall stove pipe in the center and put a grate on it! That works super well!

Awesome content friend!! I love what you did and i need to replicate for myself! One suggestion, id continue with the threaded studs so you can use a coupling to adjust the level difference when not on perfect ground. Either way this is an amazing rocket stove! Thank you

That cordless saw used to cut the firebox hole is amazing and fast! Where can I get one of those?
