Irish rocket heater cooker plans FREE

I made this 5 years ago and it is still working great. Ive modified the firebox but the basics are unchanged. It works great in my 32 foot trailer.

Here is the video of its construction

Nice video, this forum has many hundreds of post stating that steel wont last in a rocket stove so your video is an interesting one.
As far as I can work out, if you insulate the fire box and heat riser the temperature will get so hot the metal will quickly deteriorate but if you don’t insulate then the fire will not burn very cleanly.
However it seems to me that metal rocket stoves have a strong presence and are by far the most popular.
Yours is a good example of how a metal rocket stove can be used successfully for many years.

The riser is insulated only. It works well for me but i am planning to make 'the most perfect rocket stove' some time soon...🤣😲🤓
This year will be my 5th winter.
Thanks for the considered response.

The metal thing is for rocket mass heaters that are burning 24/7.
Rocket ovens don't get the same use and extremes of temperature.
But one could just measure the temperatures to see if they are at a level that the steel is going to spall.
