I would like to see if I can easily build a homemade electric load bank, to test generators. To that end, I would like to buy electric water heating elements, connect them in parallel, with each of them separately switchable, and submerge into a water container. Before power is supplied, I would connect a garden hose and run water through this container (which could even be simply a bucket).
Does this setup make sense?
If so, which heating elements would you suggest?
