TL;DR
Heatbit has unveiled Bitwater, a water heater component that uses 20 Bitcoin mining chips to heat water.
The device delivers up to 34 TH/s of mining power while consuming a maximum of 600 watts. Its starting price is $899.
The first units are scheduled to ship in the first quarter of 2027. The company aims to use electricity already needed for hot water to mine Bitcoin.
Heatbit has unveiled Bitwater , a water heater component that replaces traditional electric heating elements with 20 Bitcoin mining chips . The device uses the heat generated by the processors to warm water while simultaneously mining BTC.
The device uses Bitmain BM1370 chips and delivers a maximum hashrate of 34 terahashes per second (TH/s) , consuming up to 600 watts . According to the company, water directly cools the processors, eliminating the need for fans.
Bitwater is designed for installation in conventional 30- to 80-gallon electric water heaters used in the United States and Canada. Heatbit says no plumbing modifications or additional electrical circuits are required.
Introducing Bitwater: the water heater element that mines Bitcoin.
It screws into the electric tank you already have.

Heatbit Enables Bitcoin Mining While Heating Water
Unlike conventional 4,500-watt heating elements, Bitwater operates at lower power and needs to run for longer periods to heat the tank.
The existing upper heating element can provide additional heat when hot water demand increases.
Users will be able to monitor water temperature, mining hashrate, and earnings through an app . They can also choose between solo mining and joining a mining pool , with rewards sent to an address they control.
The first production batch, called Genesis , is available for preorder at approximately $899 . Later batches could cost up to $1,299 , with initial deliveries scheduled for the first quarter of 2027.
Earnings Will Depend on Mining Difficulty
Heatbit has not published its own profitability estimate. According to calculations from external sources, a device operating at 34 TH/s could generate approximately $1.25 per day , equivalent to around $455 annually , under current mining conditions.
This figure does not represent guaranteed net profit and may vary depending on the price of Bitcoin , network difficulty, and operating hours.
The company says Bitwater is designed to operate more than 80% of the time and that it has tested the device in homes in New York and Florida.
Heatbit also aims to expand home-based Bitcoin mining. According to its estimates, households consume approximately 300 TWh annually to heat water, compared with around 170 TWh attributed to the Bitcoin network.
