Heatbit launched the $899 Bitwater component, heating water while mining Bitcoin
Heatbit, which previously launched a heater with a built-in Bitcoin mining machine, has announced the release of a heating element for water heaters named Bitwater. This element replaces the resistance wire in standard electric water heater elements with 20 Bitcoin mining chips, using the heat generated by the chips to directly heat the water in the tank. Heatbit stated that this electricity was originally intended for heating water, "the same heat, the same electricity, plus Bitcoin." The company claims that global households use approximately 300 TWh of electricity annually for heating water, which exceeds the entire Bitcoin network's consumption of about 170 TWh, advocating for the decentralization of mining to households.Bitwater uses 20 Bitmain BM1370 chips, with a maximum hash rate of 34 TH/s, a maximum power consumption of 600 watts, and an energy efficiency of 12 joules/TH. Due to water cooling, this element requires no fans and produces no noise. The installation process is DIY: turn off the circuit breaker, drain the tank, unscrew the old element, and then screw in the Bitwater using the included wrench. It is compatible with the one-inch standard interface of 30 to 80-gallon electric water heaters commonly found in the United States and Canada, including brands such as A. O. Smith, Rheem, Bradford White, Whirlpool, and GE, without the need for plumbing modifications or additional circuits.Users can check water temperature, hash rate, and earnings through an app, and choose to mine individually or join a mining pool, with mined Bitcoin sent to an address controlled by the user. The initial "genesis batch" pre-order price is $899, with subsequent batches priced up to $1,299, and pre-orders are refundable, with plans to ship in the first quarter of 2027. Heatbit claims to have tested the entire winter in four and five-person households in New York and Florida. Based on the current hash price of approximately $36.73/PH/s/day, the full load of 34 TH/s could mine Bitcoin worth about $1.25 per day, totaling approximately $455 annually.
