Performance You Can Count On
The UNI Wood Boiler ensures clean combustion with micro air metering in both lower and upper fire chambers, guaranteeing efficiency of 86% or higher. Exhaust gas temperatures remain below 260°F to 300°F, even under heavy load. When combined with a buffer tank, the gasification mode allows for maximum energy extraction from solid fuels.
Built for simplicity, reliability, and power, the UNI is a heat source you can trust for even the most demanding commercial applications.
