This is awesome. I would like to make something lie this but really small. I only have 2 small water heaters that hold 1 and 2 gallans. We use them when we need to shower or wash dishes. There has to be a simple way to heat that water with one of my miners. Heating a small space is nice but that is generally needed at night and we are all solar off grid. So this seems more useful. This has my wheels turning. thanks.
