Heatbit introduces Bitwater Bitcoin mining water heater element

Heatbit, a Delaware-based company, has announced Bitwater, a replacement heating element designed for electric water heaters that doubles as a Bitcoin mining device. Instead of using traditional resistance wire, the unit incorporates twenty Bitmain BM1370 mining chips to generate heat while performing computations.

The system is designed to screw into existing 30- to 80-gallon electric water tanks commonly used in the United States and Canada, including brands such as A. O. Smith, Rheem, Bradford White, Whirlpool, and GE. The water in the tank serves as a direct cooling mechanism for the chips, which eliminates the need for noisy cooling fans.

Technical specifications include a maximum power draw of 600 watts and a hashrate of up to 34 terahashes per second (TH/s). A companion app allows users to monitor water temperature, hashrate, and mining earnings. The company has opened refundable preorders for the first production batch at $899, with shipments expected to begin in the first quarter of 2027. Subsequent batches are expected to cost up to $1,299.
