HVAC system addition (idea)

More of an idea.

A heating system to complement the Aircon unit.

A bigger wall heater with built in fan to push air though.

One thing I miss is the turbine generator they sadly removed as I used to use that as a reference when it spins I knew I had good air flow. So though about having something similar. One powered and one that spins freely.

Not sure if it would work but including ventilation shafts same size as the chutes.
