Time-dependent solutions to temperature change across a gradient are exponential decay functions that solve diff eqs based on Newton's law of cooling. It depends mostly on the insulation and the temperature difference.

While it is 10 F outside, the central heating system for my apartment in a 6-story building cannot maintain temperature. It is 66 F and gradually falling. I would guess it would be 2.5kW running 24/7.

25KW more likely

Probably closer to this than 2.5kw. 2.5kw on a decently modern heat pump should be providing 25k btu. About enough to heat a 2000sqft house ~50f over ambient.

I have a 2.4kW heater in my bedroom...

Just in case anyone is about to miss this detail:

That heater probably doesn't run continously.

For a well designed shared system you can get away with less than n x what an individual unit needs.

(That said, I too guess 2.5kW is too small for what GP mentioned.)
