Wow! This is the first time I hear something like this! I had heard about Bitcoin mining heaters (which we don't need in Florida) but are still pretty cool. Can you imagine a heater that pays itself? Just wow. If you hear about water heaters that do this please share the link.

I also see a lot of potential for animal farm heaters. It would be a great way to generate extra income on farms for energy you are going to spend anyways. Damn, I just came up with a great business idea!
