Heatbit has introduced Bitwater, a water heater element designed to mine Bitcoin while heating water. The device replaces the standard resistance wire in electric water heaters with 20 Bitmain BM1370 mining chips. It operates at up to 34 terahashes per second and consumes up to 600 watts of power.
The element is compatible with standard one-inch ports on 30- to 80-gallon electric tanks in the U.S. and Canada, including models from brands like Rheem, Whirlpool, and GE. Installation is intended for DIY use, requiring no plumbing modifications or additional circuits. The water serves as a cooling system, eliminating the need for fans.
Users can monitor temperature, hashrate, and earnings via a dedicated app, with options for solo mining or pool participation. Heatbit estimates daily earnings at approximately $1.00 to $1.25, though it notes these figures depend on Bitcoin prices and network difficulty.
Preorders for the initial production run are priced at $899, while subsequent batches will cost up to $1,299. The company expects to begin shipping in the first quarter of 2027. Heatbit previously released a space heater with integrated mining capabilities in 2023.
