Fire MAPS continuously monitors performance of key combustion indicators in the wood stove and delivers real-time user guidance and burn status to the user. In turn, the user interactively learns how to properly control the wood stove throughout the lifecycle of a fire. Stove users, equipped with timely guidance based on real stove performance data, can optimally operate the wood stove as it was intended, thus resulting in lower emissions and increased efficiency, saving on fuel costs while improving the environment and air quality.
