Learning methods and outcomes

We will work as a group and construct this fine example of a rocket mass heater which will heat our a farmed cabin building and as such be used as an example of this sustainable energy generation system. We will be able to light it and experience it in action. The course will give you an introduction to the world of mass heaters, and perhaps be a jumpstart to explore mass heaters and rocket stoves in more depth.

Course Instructor

Sara Tommerup: Sara is a trained natural builder and has built many rocket stoves along the way. Although there are many ways of heating your home, the rocket stove has a special place in her heart. Sara learned to build the rocket stove from its inventor, Ianto Evans.


Coed Talylan is a 70 acre woodland on the western edge of the Brecon Beacons. Nestled below the iron age hill fort of Garn Goch in the foothills of the Black Mountain it offers a secluded and peaceful location for our course participants to learn and explore the potential of applying agroecology within a co-sufficient community settlement.

Accommodation is available for camping around our guest lodge, an A-frame wooden cabin with kitchen and dining/living space. We have running filtered spring water throughout the site, compost toilets and wash facilities.

We will email directions when you sign up to a course.


We endeavour to make our courses and events affordable to all. Unfortunately, we do not receive any external funding and rely on large amounts of voluntary input. Concessions are available for pensioners, unemployed and full-time students only.
