Electricity generated heat from your servers is incredibly inefficient compared to a heat pump.
Conversely it's exactly as efficient as a resistive heater, which lots of people still use.
Interesting thought experiment - is a pc exactly as efficient as a resistive space heater? In a pc some tiny amount of electricity is converted to light and sound and kinetic energy instead of heat. But then again, don't those other forms of energy just eventually just turn back into heat again? Hmmm...
I would think actually more efficient because heat is the waste product not the expected product like a stand alone heater. Unless you are specifically running your PC at max just to create heat then just using your PC as intended and gaining "free" heat is a bonus.
