This is very interesting. We were considering one of those Esse stoves to replace our old Rayburn in a house we mainly use in the summer - but have decided to wimp out with bottled propane because all range cookers put too much heat in the room in summer. There is also the WAF to consider inside the house... We'll put in a small modern woodburner for quick heat in the winter.
However I've often wondered about retrofitting a rocket engine to the Rayburn; I plan on moving it to an outbuilding to tinker with. The oven is totally shot, paper-thin rusted cast iron. My plan is to remove the Rayburn's grate and boiler and replace it with a rocket heat-riser exhausting just under the hotplate, then ducting the flue gases round the oven and back under the simmering end of the hotplate before exhausting to the flue. It will need considerable modifications to the gas-flow in the Rayburn, the oven is normally only heated by conduction from the fire side. I'm also going to experiment with woodchips as the fuel. We get a lot of brash from the orchard and hedges which usually gets burned in a big bonfire once or twice a year; better to chip it and use it as fuel.
