So again.. WHY THE HELL ISN'T THIS JUST STANDARD ON AN ELECTRIC WATER HEATER IF ITS BETTER?! Like.. wtf? There's already electricity going to my water heater! It would be *trivial* to install at the factory and seal it up never to even need to be opened again, tbh. And it's shorter and therefore less materials, too. I don't get it. Now I have a power brick *and* a hard wired wire going into my water heater. Just... why? So many appliance and home things are like this - patchwork.
