You could mine bitcoins too.

If you’re at the temp a heat pump won’t work, resistive heating will likely be tens of thousands a year. A furnace will be more economical.

If you’re somewhere warmer, then a heat pump will be more economical than resistive heating.

The only economical or useful thing about resistive heating is the installation price. But use it for a handful of years and heat pump (even from decades ago) will be better.

Which area is that?

I find it bizarre that places have resistive electrical heating. Like how in this day and age do you have resistive heating instead of a furnace or a newfangled heat pump.

For stuff like this you can get used equipment. Or put new ones together from junked PCs.
