Roquetinho is an application of the Batch Rocket design, that has proven to be outstanding efficient and incredibly clean. Initially it was meant for Portugal, where wood burning is a common form of space heating but technology is poor – with many inefficient and dirty wood burning appliances.

But also in other countries the Roquetinho design is very well applicable. It is relatively simple, cheap, and very efficient. The hope is to make Batch Rocket technology available to as many people as possible and for the lowest possible price.

 


Update 2025:


A new update is on its way. Most important adjustments are:

  1. -the exhaust of the flue gases becomes symmetrical;

  2. -the outlet is now centered;

  3. -also the core is centered.


For now you can already find a pdf of the changes, and the new SketchUp file.


Update 2024:

The firebox sits now flush with the front of the bell and is a little easier to build. The door and frame have been adapted, and also the air inlet has been improved.


Update 2023:

The 2023 version is somewhat larger and more powerful. The riser is now constructed from 230 x 114 x 57 mm insulating firebricks, thus making it much easier to build. Concrete tiles as you find them everywhere in gardens are used to construct the bell. See the renewed Building description page.
