You can turn work into heat with friction or turbulence. You don't need electrical thingamajigs. But even "small" amounts of heat involve huge amounts of energy. If I haven't just made a mistake, it takes 40 MJ to raise a bathtub full of water from room temperature to bathwater temperature.
Better to use trees and wood for heat: The original solar power system.
