Key Takeaways
- Heatbit opened preorders for Bitwater, a water heater element with a bitcoin miner inside, on October 22, 2026.
- The $899 price applies only to the Genesis batch. Later batches are listed at up to $1,299.
- Bitwater draws up to 600 watts, about 13% of a regular 4,500-watt element, and, Heatbit's FAQ says, runs steadily rather than in bursts.
- Heatbit says mining income depends on network difficulty (how hard the bitcoin network makes it to find a block, which rises as more miners join) and the bitcoin price, and its product page says projections are not guarantees.
Heatbit opened preorders on October 22, 2026, for the Bitwater water heater element, which mines bitcoin while it heats the tank, at $899 for the Genesis batch. First units go out in Q1 2027, the product page says. Later batches are priced at up to $1,299.
The FAQ compares Bitwater with a regular 4,500-watt element and says Bitwater runs "steadily rather than in bursts." At its 600-watt ceiling, Bitwater draws up to 14.4 kilowatt-hours a day. A kilowatt-hour is the energy of 1,000 watts running for one hour. A 4,500-watt element uses the same 14.4 kilowatt-hours in about 3.2 hours, so Bitwater takes 7.5 times as long to deliver that energy.
Crypto Briefing described Heatbit as a Delaware-based company, and the product page says Bitwater screws into the electric tank you already have. Crypto Briefing reported the launch the same day. The Bitwater product page gives the specifications below.
What the Bitwater Element Replaces and How It Fits
Bitwater screws into the standard 1-inch element port on electric tank water heaters. The product page says it fits by far most electric tanks sold in the United States and Canada. Heatbit's FAQ says it suits tanks from 30 to 80 gallons. On a two-element tank, the lower element is replaced and the upper one stays. The company says the swap can be done within about 30 to 45 minutes.
Heatbit says twenty mining chips sit inside the element, cooled by the water around them. Heatbit rates the unit at up to 34 TH/s (terahashes per second) and from 12 J/TH (joules per terahash), and it lists power of up to 600 W.
The 600-watt figure matters most for household energy use. The FAQ says Bitwater "puts up to 600 W into the tank continuously," and the upper element stays as backup for heavy hot water use.
How 600 Watts Compares With a 4,500-Watt Element
Heatbit says heating water takes the same electricity whether a plain element or Bitwater does the heating. The product page gives no estimate of a household's monthly bill or electricity rate, so the arithmetic shows the scale of the element's power draw, not whether a bill rises or falls.

Who Bitwater Is For and What Heatbit Says About Mining Income
Heatbit's page is written for owners of electric tank water heaters in the United States and Canada, the only countries it lists for shipping. The company says it ran tests through a winter in New York and Florida with households of four and five people, but the page gives no figures for those tests.
Crypto Briefing reported that Alex Busarov founded Heatbit in 2020 after observing how much heat mining equipment threw off. The product page quotes Busarov: "It’s the most efficient miner there could ever be, because the electricity was spent on heating anyway."
The page says Bitwater mines solo on the Heatbit pool out of the box, so a block found is yours, and that it keeps mining at any bitcoin price because households need hot water at any bitcoin price. It also says "anyone quoting you a figure for the year is guessing," because what a unit earns "depends on network difficulty and the bitcoin price."
A disclaimer on the product page adds that "These projections are not guarantees of future earnings." Crypto Briefing listed the open questions as whether Heatbit meets its first-quarter 2027 shipping target and whether real-world units deliver the advertised 34 TH/s and 12 J/TH.
