For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

Electric water heater + water-based heat distribution & radiators
Voila
What I was thinking, was using an AC in my office and using the waste heat to heat up the water in my boiler
The HVAC technician I talked about that laughed at me and said, that's science fiction
But I don't really get why.
Wouldn't that be just a heat pump from the perspective of the boiler and an AC for my office?
Edit: to clarify, I'm aware, that I can't heat up the water to the level I want with that, but I could pre-heat it, so I don't need so much power to heat it the rest of the way
