Water Heater Controller / Scheduler
Has anyone knowledge of how to build your own second 12V water heating element? A water boiler on 220V consumes a lot and I have got a solar panel. The boiler has a space for a second heating element. That second one can run on 12V. But that one needs a thermostat of its own I guess. Is there any way that these elements and thermostat can be build?
