A comfortable temperature for every home

The Mark COMFORT LINE water-supplied air heaters are specially designed for optimal and energy efficient heating of homes.

The COMFORT LINE ensures recirculation , filtering and heated supply of the air in a building or home. This allows all rooms to be heated quickly and comfortably.

In contrast to heating with radiators, a COMFORT LINE air heater will quickly and automatically bring your home to the desired temperature. In addition to homes, the COMFORT LINE can also be used in shopping centers, offices, churches and school buildings.


Every COMFORT LINE is supplied with a Siemens controller as standard. This user-friendly and easy-to-operate control ensures perfect and worry-free operation.

Each Siemens controller is equipped with a return air sensor and a surface contact thermostat. The fan of the COMFORT LINE runs continuously at the minimum setting (adjustable). If the water temperature exceeds the set value, the controller will increase or decrease the fan speed depending on the return temperature of the air.
