For people who use resistive electric heating I've recommended them to run crypto miners on their computer. Same efficiency with regards to heating, but you can earn some extra money as a bonus.

I've done this to heat the small room I use as an office, its far more efficient than the shit electric radiator in there.

Rented house so can't do much about the absolutely useless heating setup.

I lived in a little apartment with resistive wall heaters and I did just that in the 2018 period. Even had some Raspberry Pis mining Aeon, a lightweight offshoot of Monero.
