Loading group

Loading group

Temperature security

The loading group serves as return flow maintenance before the boiler and protects it from getting demaged by condensation or corrosion, that is caused by too low return temperatures.

The loading group is available in two basic designs:
Design „electric“ to be used for Eder boilers with integrated loading group control (e.g. Biovent C/SLC/XLC, Pellevent M, Kombipell, Unit OM/OD). Design „ther mostatic“ for geral utilisation without loading group control (e.g. ECO NZ, Elko-therm Eder HW, natural draught boilers, etc.)

Designs: electric (left picture); thermostatic (right picture with manometer)
