Same results for different nominal thermal efficiency of a gas boiler in Ironbug

Dear Ladybug community,

I would like to change the nominal thermal efficiency of a gas boiler from 0.8 (default value) to 0.7 as shown below:

The results on the heating demand and EUI remain the same for both 0.7 and 0.8 efficiency:

Is there something I missed?

Thank you!

No one experienced this before?

There are a million of reasons that could affect building’s heating.

To verify if your setting works expected, you will need to check the hourly heating energy directly from boiler. That’s the direct output that affected by boiler’s input settings.
