So we need a water heater anyway...

A new water heater component aims to turn everyday hot showers into an opportunity to earn cryptocurrency. Developed by Heatbit, the Bitwater replaces a conventional electric water heater element with a built-in Bitcoin mining system that generates heat while attempting to earn digital currency.
The device combines 20 application-specific integrated circuit (ASIC) mining chips with a heating element designed for existing electric water tanks across North America. Heatbit says the system can be installed in a standard 1-inch screw-in port and connected to Wi-Fi to begin mining Bitcoin.
The Bitwater uses BM1370 mining chips that collectively consume up to 600 watts of power and deliver a peak hashrate of 34 terahashes per second. Hashrate measures how many calculations a mining system can perform each second. The chips generate heat during operation, which is transferred to the surrounding water through specially designed Eco Brass heatsinks.
The potential earnings remain uncertain. Heatbit has cited an estimate of $1.35 per day in Bitcoin revenue, but that figure does not account for electricity costs. Actual profitability will depend on local power prices, Bitcoin’s market value, mining difficulty, and the amount of time the system operates.
The price is another consideration. Heatbit plans to sell its first batch for $899, with shipments targeted for the first quarter of 2027. Later batches are expected to cost $1,299. By comparison, conventional water heater elements with powered anode rods can cost considerably less.
