Boiler design

Flexible flue connection X
Choose from steplessly adjustable to the left or right – perfect for renovations.
Ideal temperature stratification X
With the MESplus layered loading function, temperatures of up to 80°C are transported to your heat accumulator in a controlled manner.
Filling chamber made of quality steel X
Durable boiler construction with a filling volume of 145 litres for long replenishment intervals.
Automatic ignition (optional) X
Heating material no longer needed with automatic ignition.
Attachable ash trap X
Attachable ash trap prevents ash dust being stirred up during cleaning and keeps the boiler room clean.
Robust combustion chamber X
The patented, divided combustion chamber ensures smooth operation for many years.
LambdaTherm control X
The combination of lambda and thermal sensors with integrated output adjustment ensures clean, efficient combustion and high ember quantity.
