Welcome to the Rocket Stove Institute

This is the video from the Beloved Festival 2018 showing the SR100 rocket stove heating water to do dishes for 3,000 people for four days. I have updated the text narrative below the video which tells the current history and future plans for the SR100.
The above video shows the SR100 rocket stove configuration. It includes the SR100 Rocket Stove with three 24 inch sections of double layer stainless steel insulated 8 inch ID chimney sections, a coil in the chimney in direct contact with the chimney heat made from 60 feet of 3/8 inch ID copper tubing bent into a 48 inch long coil to fit into the chimney. The pump is mounted at the bottom of the tank and pumps the water through high heat PEX tubing up into the top of the coil winding to the bottom of the coil and then straight up to the top of the chimney and then returning to the tank. This configuration was able to heat 125 gallons to 155 degrees F in 2.5 hours and we reproduced this in several burns. We were able to heat the water at a rate of 39,000 btu per hour and we feel we can double this rate with the improvements we are making.
This is the video of the burning SR100 Rocket Stove with long chimney and copper coil.
Notice the speed of the flames.

Turn the volume up and listen carefully to the sound that the rocket stove is making as it draws air into the combustion chamber directly into the fire to get a kinesthetic feeling for the burning process.

Notice the heat level.

The SR100 is designed to burn at this rate continuously 24 hours per day for six months


The creation of the SR100 rocket stove was inspired by the courage of those in the Standing Rock 2016 effort to safeguard the purity of our water. The purpose of the SR100 rocket stove is to provide continuous heat to keep people warm in their homes, to heat greenhouses and workspaces, and provide hot water, in winters that last up to six months with temperatures down to minus 17 degrees. “SR100” refers to a rocket stove engineering specification for the combustion chamber which states: The SR100 Rocket Stove shall be capable of producing 100,000 btu per hour 24 hours a day continuously for six months without failure. The “SR100” specification was written by, and the prototype SR100 rocket stove, seen in this video, was designed and built by John Robert Zielinski under the mentorship of Dr. Larry Winiarski, ten year best friend and inventor of the rocket stove and author of the “Ten Principles of Combustion”. Nick Moses, formerly of the Instove Corporation, rendered the SR100 design in Autocad and CNC cut and formed the stainless steel exoskeleton to hold the firebricks to create a combustion chamber similar to a forge. After the Beloved Festival the pot was replaced by a long chimney with a copper coil inside. Several measured burns confirmed that the SR100 is capable of heating a large tank of water, which stores the heat, and then the water can be pumped to heat a house, a greenhouse, a workshop and a hot tub, thereby demonstrating that the SR100 can function as a central component of a homestead allowing it to be more sustainable and more capable of off-the-grid living. Special thanks to the staff at the Oregon Country Fair Ritz Sauna for guidance in choosing to develop the copper coil technology which is several times more effective than using a pot.

The Rocket Stove Institute is in the process of refining the design and finalizing a real-time demonstration system. We are creating an Indiegogo campaign to be launched mid to late summer 2019 with a second video showing the full potential of the SR100 to fund the development of new features that will include:

  • a hopper that will burn wood pellets or chips continuously for up to four hours or longer with one filling
  • a microprocessor controller run by solar energy which will maintain the proper ratio of air-to-fuel for the cleanest and hottest burn
  • a new technique to manufacture stoves quickly by casting them out of a cellular refractory which would bring the costs way down to around $10 and allow for multiple stoves to heat a tank several times faster.
  • a pioneering new method to create water tanks made on site quickly and inexpensively which are insulated with cellular cement.
  • This size of a rocket stove has been laboratory tested to emit 90% less pollution and use up to 90% less wood (biomass) than an open fire.

    This video was independently produced by the Rocket Stove Institute.

    All interested parties, people who want to help the world, and lovers of the rocket stove are invited to contact us for more information, apprenticeships, employment, products and opportunities.

    Stay tuned for the launch of the Indiegogo campaign.
