Information

1. Purpose of model

Controller for the operation of a CHP unit and a boiler. CHP is operated at constant heat output as long as the storage tank is not full.

The boiler will switch on additionally if the storage tank state of charge drops below threshold value. The boiler has a modulating power output so that the storage tank level stays at set point value.
