Frequently Asked Questions About Hybrid Technology

As you read through our literature you will find that we refer to the burn system in a Kuma stove as a hybrid burn system. So what does that mean? Our stoves combine 2 distinct burn systems into the firebox each with their own unique advantages. The first is the thermal combustion system (burn tubes). Burn tubes work great at temperatures above 1000° delivering secondary combustion air to incinerate most of the smoke. The second is the catalytic combustor system which lowers the temperature at which wood smoke will burn down to 500° so on medium and low burn rates, hybrid stoves will continue to burn super clean and efficient. Our entire line of low emission hybrid stoves and inserts comply with EPA 2020 requirements and qualify for the 26% Federal Tax Credit.
