No pilot or Jet mechanic but afaik the pressurisation is happening with bleed air from the turbines that is then cooled down to comfortable levels. So there is no "heater" for the cabin so to speak as for a warmer cabin you just cool down the bleed air less. As such without pressurisation there is also no cabin heat.
You just causally knew that offhand, and it's not even your industry??
prolly went down a wikipedia rabbit hole or something
I am weirdly nerdy about planes. Always wanted to be a pilot as a kid.
