Heatbit offers the Bitwater water-heater element priced at $899. According to the available description, it replaces the usual heating coil in the tank with 20 chips for Bitcoin mining, and the company itself states that the device uses the same electricity to heat water.

The significance of the idea lies in attempting to merge household energy use with computation, but at present the outcome for the owner cannot be assessed: the source provides no data on mining speed, costs, revenue, compatibility with tanks, or safety. The information is based on metadata from Decrypt's publication rather than the full text or independent confirmation.
