Rocket Stove!

[one_rod]

Anyone else made or used one?

There’s plans and instructions for building the things all over the net, from tiny backpacker versions to monsters big enough to heat a building. And they really do work.

Produce an incredible amount of heat from a small amount of fuel. In the video below I really did cook that pan full of sausages and then boiled a pint of water for a brew up on those few sticks. Even then it was nowhere near burned out, there was plenty of life left in it.

The pics should show how I built mine, from junk, basically. A big tin can and some bits of old extractor ducting. Only took a couple of hours.

And that’s all there is to it!
So here it is in action.

Brilliant video ,,, well made stove ....

[zorro]

:lol: That's brilliant Mick. :D

Are you bringing it to Hillholt? :)

[Damascene]

With one of these and a haybox you can cook a meal using no gas or leccy at all. :)

[rapidboy]

Brilliant :D

[HPFlashman]

hmm, interesting... Thumbs up and all that... :)

[davidwatson]

I like that,might just have a go.

[pippyd]

Great stuff Mick, brilliant as always :)

What's the purpose of this piece exactly?

These stoves are all about air flow. That's why the lagging is so important. Creates very high temperature in the vertical chimney, so maximum convection and max combustion efficiency.

That little plate creates a gap under the fuel in the horizontal section, stops you filling it completely with sticks and strangling the air flow.

excellent device.

[ArkAngel]

Fantastic bit of recycling, great job!

[pippyd]

Makes sense :) Any plans to make a mini one?!

I'll have a look around for some tiny bits of scrap metal. ;)

:D. What sort of sizes have you seen people make them?

I made one from a three gallon size grease tub with a handle, I used 75mmx75mm trunking for the fire tube. For the insulation I bought a small bag of vermiculie from the garden centre(the only bit I had to buy). It works brilliantly for boiling the kettle, havent tried it for cooking on yet but would think it will perform well because you can very easily control the heat by moving sticks in or out of the combustiojn area. Its not the most lightweight stove at the size I made it, it definately has advantages over the large Kelly Kettle I have as you can keep it burning for a longer time and move the kettle about on the stove just to keep it simmering. A great little project which can be built from scrap metal

[TallNHairyDave]

Nicely done one_rod mate!

Mmmm sausages

[northern787]

The book to read if you are serious about these as a heating solution is "rocket mass heaters" by Ianto Evans and Leslie Jackson.

[emardesig]

Very nice any plans to make a mini one...

[isherwood]

my dad had made quite alot of these they are very very good and you can make them to be reasonably disposable or brick built go great with a brick built bbq!

[Brian Sheehan]

Have loads of empty gas canisters in my back garden , wonder if I could make a stove for the sitting room using similar ideas , hmmmm

Rocket type heaters for inside the house are usually made from brick and tile. Northern787's book suggestion above would be a good place to start. They can be incredibly efficient in terms of fuel usage and heat output.

Simple solid fuel stoves can certainly be made from empty gas canisters. There are hundreds of designs out there. If you are looking for some design inspiration then I think THIS (http://www.hotpod.co.uk/hotpod-multifuel-stoves-form-and-function.asp) takes some beating. ;)

Cheers One Rod , will check it out

I keep meaning to try one of these having doen a few wood gas stoves

Do you think Al pipe would survive? I think I have some 60mm (internal) lying around, might make a good mini-rocket.

I also have a 150mm SS elbow from a flue.

[one_rod]

Do you think Al pipe would survive?

I don't think it would. Burning it for a while gets gets the steel pipe in mine glowing red. Well above the melting point of Ali.
Thin wall steel would be a much better bet.

we are getting our chimney lined with a flexible double wall stainless liner its then backfilled with vermiculite so i might have to make sure i get half a bag and see if they have any 4-5" stainless tube to make a patio burner ;)
