I started researching about efficient wood burning stoves when the gas and electricity prices shot through the roof. I also had some cheap source of 'scrap' wood from some furniture makers.

Surprisingly I found a lot of info on the internet.

After toying with a variety of ideas, I decided to make a stove out of a retired 'cooker'. In brief: The excess parts were removed. The L-shape of the "rocket" concept was put in place using sheet metal. And the inbuilt insulation of the cooker was left in place.
