The Vitotherm Duo-Block burner is a real workhorse. If you have special requirements concerning sound, NOx or power, the Duo-Block is there to take care of it. Our Duo-block burners are composed out of two units, connected by an air duct to transport the combustion air preheated in the burner unit towards the fan unit.

Key benefits of this setup are that the fan can be installed flexibly, which helps to significantly reduce noise levels in the boiler room. The burners are designed in close cooperation with the boiler or drum manufacture to ensure a perfect fit.
