About the SR100
Thermal Battery System
The creation of the SR100 rocket stove was inspired by the courage of those involved in the 2016 effort at Standing Rock 2016 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.
During the time of the Standing Rock protests I heard on the news that it was going to be 10 degrees below at Standing Rock. I felt so concerned for the protestors that they would be in this freezing cold weather and it would be so hard for them to survive and keep protesting. When I saw Larry the next time I said, Larry, you and I have been designing stoves for over ten years but we still have not designed a stove that I could send to Standing Rock. I said I wanted to design a stove that would deliver 100.000 btu per hour for 24 hours a day and burn continuously for six months without failure. How would you design this stove, Larry?
Larry said one word: “Firebrick”. I said, “you would design it like a forge?”, Larry said, “Yes”, I said: “I’m on it”.
This is how the SR100 was born. After the Standing Rock effort was over, the SR100 became the name for the rocket stove which met the SR100 specification. By making SR100 the name of the specification the link between the SR100 Rocket Stove and the Standing Rock effort would always be preserved.
SR100 engineering specification
The SR100 Rocket Stove is capable of producing 100,000 btu of heat per hour 24 hours a day, seven days a week, continuously for six months without failure, and cost less than $300. 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.
The specification was written by, and the working prototype SR100 rocket stove as seen in these videos, was designed and built by John Robert Zielinski, under the mentorship of Dr. Larry Winiarski, ten-year best friend, 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.
Space heating and water heating account for nearly two thirds of U.S. home energy use
Space heating and water heating were the top two energy-consuming uses in U.S. homes in 2015, according to EIA’s latest Residential Energy Consumption Survey (RECS). Space heating consumption can vary considerably by climate and building characteristics, while variation in water heating consumption is driven primarily by the number of occupants in a home. Households use a variety of fuels for space heating and water heating, which affects these end-use shares of household energy expenditures.
The above video shows the SR100 rocket stove configuration with a 72 inch chimney and a long copper coil inside the chimney directly in contact with the flames. This configuration 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. The coil is 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 coil configuration was able to heat a 125 gallon tank to 155 degrees F in 2.5 hours and we reproduced this rate of heating water in several different monitored burns. We were able to heat water at a consistent 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 rocket-like sound that the rocket stove is making as it draws air into the combustion chamber directly into the fire and get a kinesthetic feeling for the intensity of the burning process.
Notice the heat level.
The SR100 with its forge-designed combustion chamber is designed to burn at this rate continuously 24 hours per day for six months
To the staff at the Oregon Country Fair Ritz Sauna for guidance in choosing to develop the copper coil technology which can be designed with more surface area to be several times more effective than using a pot. We also understand that a coil may be more effective than a pot with the same surface area and plan to test this.

- A hopper that will burn wood pellets or locally-made chips, for a fire burning continuously for up to four hours or longer with one filling
- a pioneering new method to create water tank/thermal batteries, made quickly and inexpensively and affordably insulated with straw or cellular cement.
- A new technique to manufacture stoves quickly by casting them out of a cellular refractory we are developing which would bring the costs drastically lower.
- Multiple rocket stoves to heat the thermal battery faster just as a car engine has multiple pistons to provide more power.
- A microprocessor controller run by solar energy which will maintain the proper ratio of air-to-fuel for the cleanest and hottest burn
