A lot of houses come with water "barrels" and resistance wire inside. How hard would it be to disconnect your hot water tank circuit and tap into that?
Not hard at all. The only issue is that the thermostat and safety overtemperature cutout are only AC rated. They can not safely interrupt high voltage DC.
However, it is pretty easy to wire them to control a contactor that *is* DC rated for the appropriate voltage and current.
If so inclined, a snubber circuit may be possible to allow the stock thermostats to work. However, this would require careful testing. You do NOT want to find out the hard way that the safety overtemperature thermostat can't stop the heat!
