Updated: January 2018

The following teams filled out the letter of interest form, indicating their interest in becoming a finalist in the 2018 Wood Stove Design Challenge. The Organizing Committee selected these eight stoves for the initial round of finalists. More will be selected in early 2018.

New Design Challenge Applications


Institution: University of California Riverside
Location: California, US
Category: thermoelectric
Team Leader: Venkatadriagaram Sundararajan
Other Team Members: Eddy Ayala, Qiyang Sun, Carlos Nunez, James Lawman

The Barrel Burner has a cylindrical combustion chamber with an additional chamber to reduce the moisture content of the wood fuel before placed into the combustion chamber. The stove will be equipped with air flow and chemical sensors placed in strategic locations. These signals would be used to determine the excess air levels required to improve the combustion process for a specific phase.


Company: Unforgettable Fire
Location: Vashon, WA
Category: Thermoelectric
Team Leader: Roger Lehet

The Kd2 is a vertically stacked dual firebox with a patented gasification system. Fuel efficiency is maximized and emissions are minimized by burning the returning gases created in the primary combustion chamber. The “Kd2” wood stove is capable of creating electricity via water-cooled thermoelectric generators attached to the exterior sidewalls of the stove. The stove can also heat water for domestic hot water needs, or for hydronic heating. In addition, the electrical power control center can accept additional electrical input from solar panels and wind generation systems.


Company: HastyHeat
Location: Estacada, Oregon
Category: Thermoelectric and Automated
Team Leader: Brent Hasty

Stove Name: CHP
The CHP stove is an automated and thermoelectric modular pellet stove with a turbine engine style tube in tube can combustor. This stove induces super-heated secondary combustion air forming an intense high-agitation and mixing flame vortex. The CHP's combustion process is designed to conserve both thermal and kinetic energy while providing a long serpentine combustion path for complete combustion. The CHP will include integrated liquid cooled thermal electric generators.

509 Fabrications Inc

Company: 509 Fabrications, Inc.
Location: Post Falls, Idaho
Category: Automated
Team Leader: Dusty Henderson

Stove Name: Optimum
The Optimum is an automated stove that burns Presto Logs. These compressed wood logs have been around since about the 1920's, but until the last 10 years or so, they have been poorly made. The logs now are very dense and contain from 43,500 BTU's to almost 70,000 BTU per log. The logs are gravity fed into the firebox and the Optimum will hold 3 or more logs. The logs burn on their end rather than flat and the stove is verified at 79% efficient.

Vestal EcoSynergy Heat System

Institution: New Clean Earth
Location: Cortland NY
Category: Thermoelectric and automated
Team Leader: David Gower

The Vestal EcoSynergy Heat System is an automated and thermoelectric stove that incorporates flexibility, modularity, and innovative technology to provide synergistic value from the comfortable heat that it produces. The core unit design is based on firebox solutions manufactured by Piazzetta with over 50 years of experience creating highly reliable, high quality stoves and heating systems.

Wiseway Stove

Institution: Hi-Z Technology, Inc and Northwestern University
Location: San Diego, CA
Category: Thermoelectric
Team Leader: Fred Leavitt

The Wiseway stove is a pellet stove that operates using no electricity. It has already been EPA certified as compliant to the 2015 regulations. Hi-Z and Northwestern University will add a water cooled thermoelectric generator (TEG) to the Wiseway stove that can produce up to 100watts of power.


Company: Cygnoides Smart Energy Tech. Co.,
Website:N/A Location: Beijing, China
Category: Thermoelectric and Automated
Team Leader: Min Chen

The ReBao is a thermoelectric and automated stove used in domestic heating, where heat and power can be produced simultaneously in a more efficient manner. The stove uses an MPPT buck/boost converter to manage power from the thermoelectric generator for recharging battery, and powering a pump, fan and WIFI system.

Initial Round of Finalists


Company: MF Fire
Location: Maryland, US
Category: automated
Team Leader: Taylor Myers

Stove: “X”
A highly automated stove making use of machine learning and novel combustion techniques to deliver a clean and unique fire.


Company: Aprovecho Research Center
Location: Oregon, US
Team Leader: Dean Still

Stove: Downdraft Rocket
Designed for heating and cooking in the developing world, this stove uses an improved, low cost TEG to produce 5 watts of power for lighting and charging cellphones. The combustion chamber, catalytic converter, and chimney lower emissions in an attempt to protect the health of biomass users.


Company: Wittus-Fire by Design and HE Energy
Location: New York, US
Category: thermoelectric
Team Leader: Niels Wittus
Other Team Members: Alyce Wittus, Patti Boker Elkon, Sandra Lena, Gail Jankus

Stove: E-Stove
The E-Stove was designed by German company HE Energy GmbH. The e-stove is a living-room-based combined heat and power unit developed for the production of electricity, heat and hot water. An essential element of this new product is the use of thermoelectric generators (TEG), which allows the direct conversion of thermal energy from the wood fire into electric energy.The current yield of 250-watts can cover the basic energy required by pumps and controls for the heating of buildings, hot water, LED home lighting and mobile devices.

KIWI 2.1 VcV

Company: VcV/ Flamekeepers/ Kiwi Stove Company
Location: New Zealand
Category: automated
Team Leader: Brian Gauld
Other Team Members: Eric Schaefer

Stove: Kiwi 2.1 VcV
The Kiwi 2,1 VcV hybrid stove is the first stove certified by the US EPA based upon test results obtained when cord wood was used as the test fuel. The weighted average emission rate was 1.3 g/h and that includes the emissions from a cold start high burn. The overall weighted average efficiency was 77.2%. The Kiwi 2.1 is equipped with the variable choke venturi (VcV) combustion air flow control technology that enhances both emissions reduction and increases overall efficiency. The VcV technology is also very consumer friendly in that a stove can be set to the Low burn setting right after a fuel load is added but the Primary VcV will not close until the stove has achieved a sustainable Low burn operating temperatures.


Institution: Stony Brook University
Location: New York, US
Category: automated
Team Leader: Jake Lindberg
Other Team Members: Aristidis Mihalos and Kevin Riegel

Stove: Lumburnator
The Lumburnator is a research project being undertaken by the Materials Science and Chemical Engineering Department at Stony Brook University, with the aim of building an exceedingly efficient wood burning stove. The Lumburnator is a test stove built symmetrically to operate in either updraft or downdraft configuration. It features a novel firebox design coupled with an electronically controlled air-flow system and exhaust remediation technology.


Institution: Maine Energy Systems
Location:  Maine, US
