No Gas, No Wood — This DIY Stove Heats a British Home All Winter for FREE

I uncover how a rough rocket mass heater turned a freezing Brecon Beacons barn into a warm space using salvaged materials and small pieces of dry wood. I break down the burn chamber, feed tube, heat riser, steel barrel, cob and thermal mass, explaining how the design burns wood cleanly and stores heat long after the fire goes out. I also cover which materials and fuels to use, how to light it safely, and why dry wood matters. I finish with running advice, UK Building Regulations, HETAS certification, carbon monoxide precautions and the flue detail that determines whether the whole build is safe. 0:00 Graham’s barn and the heat that lasts 2:04 Salvaged materials and the burn chamber 4:21 The heat riser and complete combustion 6:45 Thermal mass that stores heat 10:28 Free fuel and the right wood 13:55 Lighting the heater safely 16:15 Running it and meeting UK rules 18:39 The flue and essential safety
