Heatsource modelling with scalarSemiImplicitSource - room temp keeps increasing

Hello everyone,

I have been trying to model multiple heat sources with different values in a simple room with hvac ON. I am using buoyantBoussinesqSimpleFoam and have added topoSet and fvOptions to integrate the heat source/s.

The simulation is working as expected but my problem is that the temperature of the room keeps rising (attached gif). When I run the room without any heat source the temperature converges to inlet velocity (15°C) so there is certainly a problem in the way I am modelling the heat source.
I have attached the case folder for reference.

Can someone please have a look and help me in figuring out what I might be doing wrong.

Thank you very much!!
Regards
Saket
