This won't work for long if everyone in the building starts using the same trick. Better keep that box fan hidden from the neighbors.

That assumes that there's a fixed amount of heat being input into the hot water (steam?) circulation system.

Are there modern boilers that adjust the amount of fuel added and/or the burn rate, based on the incoming water temperature? Did traditional boilers just eject the excess as waste heat (perhaps through a steam pressure relief valve)?
