The high-efficiency PRS twig stove β no LPG, no charcoal, no electricity.
Dhoorandar brings field-tested PRS rocket stove technology to Indian homes. Burn 90% less wood than your traditional chulha. Cook faster. Breathe cleaner. Pay nothing for fuel β ever again.
For 70% of rural India, cooking means burning wood, crop residues, and dried dung on open fires or traditional mud chulhas. This isn't just inefficient β it's deadly.
The smoke from these fires is the leading cause of death for women and children in rural India. Not accidents. Not infectious disease. Daily cooking smoke.
Traditional mud stoves burn at only 300β400Β°C and consume enormous amounts of wood β most of it goes unburnt, releasing toxic smoke that fills homes with no ventilation.
Climate scientists call it one of the largest sources of black carbon globally β a potent climate forcer that accelerates Himalayan glacier melt.
The PRS (PΔnval Rocket Stove) is a partial gasification rocket stove developed over 15 years of research and field testing. It's the most thoroughly validated clean cookstove design in India β and it's finally available under the Dhoorandar brand.
No LPG. No kerosene. No charcoal. Just small dry twigs collected from your own backyard or nearby. Free and available everywhere in India.
Lights in seconds. Reaches cooking temperature almost immediately with minimal smoke. No waiting, no frustration β just start cooking.
Engineered airflow creates a powerful draft. Burns at 600β900Β°C β nearly double the temperature of traditional stoves β for maximum heat from minimum fuel.
Partial gasification burns wood gases almost completely, producing far less particulate matter than traditional fires. Better for lungs, better for the planet.
5.5 kg metal construction β take it camping, store for emergencies, use in the kitchen or outdoors. Built to last decades.
No electricity, no blowers, no pressurized fuel, no spare parts to buy. Just steel and fire. Cook for years with no running costs.
The PRS has been independently tested and validated over 15 years. These are measured performance metrics β not marketing estimates.
Thermal efficiency of 28β36% means nearly all the wood's energy goes into cooking food, not into smoke. Compare that to traditional chulhas which waste 85β90% of fuel energy.
Actual field results from PRS users β with exact quantities of twigs needed.
All measurements from field trials. "Twig" = dry stick, ~finger-thick. A typical gathering from a short walk yields enough for one meal.
Gather 10β20 small dry twigs. Takes 2 minutes. Free.
Place twigs in the combustion chamber. No stacking required.
Ignite. Rocket effect starts in seconds. Cook your meal.
Ash settles. Let cool. Wipe clean. Ready for next time.
No LPG cylinder to fill. No charcoal to buy. No electricity needed. Just twigs β and the discipline of an engineered rocket stove.
