Information

1. Purpose of model

Partial model for small gas boilers.

2. Level of detail, physical effects considered, and physical insight

(Purely technical component without physical modeling.)

3. Limits of validity

(Purely technical component without physical modeling.)

4. Interfaces

10. Version History

Model created by Paul Kernstock (paul.kernstock@tu-harburg.de) July 2015

Revised by Lisa Andresen (andresen@tuhh.de), Aug 2015

Modified by Anne Hagemeier (anne.hagemeier@umsicht.fraunhofer.de), July 2021 (added switch to prevent that boiler generates heat when T_return > T_max )
