I still haven't replaced mine even though that was part of the reason I sold some gold and silver. I reached out to them to find out more. Hopefully they ship to Canada and if they do it doesn't cost almost as much as the water heater. Haha

I'm sure I'll want to do this whenever we're looking for a new water heater, just because it's so cool.

I think on the website it estimates that the water heater would offset 80% of the electricity costs. That would be pretty great even if Bitcoin's price didn't appreciate much.
