**Heatbit** is a Delaware-based company founded in April 2020 by Alex Busarov. Its appliances use [Bitcoin](https://iq.wiki/wiki/bitcoin)-mining hardware to generate heat for household space or water heating; some models also purify air. Heatbit presents this approach as a way to make [mining](https://iq.wiki/wiki/mining) part of household energy use rather than relying solely on dedicated mining facilities.[\[5\]](#cite-id-odlg8mf2ze)​[\[1\]](#cite-id-cpktiohgnb)​[\[2\]](#cite-id-zg154clts6)​

## Overview

Heatbit builds household appliances that combine [Bitcoin](https://iq.wiki/wiki/bitcoin)-mining hardware with useful heating. Earlier devices applied this approach to space heating and air purification, while Bitwater uses heat generated by [mining](https://iq.wiki/wiki/mining) chips for electric tank water heating. Heatbit identifies Bitwater as its current announced product and targets first shipments for the first quarter of 2027.[\[8\]](#cite-id-8gykqqyvb2)​[\[1\]](#cite-id-cpktiohgnb)​

## History and Products

Heatbit says it has designed and shipped heating and [mining](https://iq.wiki/wiki/mining) hardware since 2020. Its early products combined [Bitcoin](https://iq.wiki/wiki/bitcoin) mining with space heaters and air purifiers. The company’s Heatbit Maxi is a heater and miner; the Heatbit Trio combines a smart heater, miner, and air purifier; and the Heatbit Canvas is a radiant-heating art piece. Heatbit has also promoted Bitair, a HEPA air purifier containing a Bitcoin miner that the company describes as quiet and suitable for placement around the home.[\[2\]](#cite-id-zg154clts6)​[\[1\]](#cite-id-cpktiohgnb)​

Heatbit’s first space heater containing a miner sold for nearly $700 in 2023. Founder Alex Busarov argued that the device could continue to generate [mining](https://iq.wiki/wiki/mining) revenue while providing heat that a conventional heater would otherwise have to produce. Heatbit’s earlier products received a CES Innovation Award Honoree recognition, and were reviewed by Wired and The New York Times.[\[3\]](#cite-id-d1wdnsyd1a)​[\[2\]](#cite-id-zg154clts6)​[\[1\]](#cite-id-cpktiohgnb)​

Sources report that Heatbit pursued crowdfunding in 2021. In its November 2022 release, Heatbit described a Kickstarter campaign; Entrepreneur reported an initial Indiegogo campaign that raised more than $40,000 in its first week before Indiegogo shut it down.[\[6\]](#cite-id-4234zbxirs)​[\[7\]](#cite-id-zth6izivhr)​

In November 2022, Heatbit said it planned a fundraising campaign aimed at ordinary users. In its December 2024 profile, [Bitcoin](https://iq.wiki/wiki/bitcoin) Magazine described Heatbit as privately held and listed 25 employees.[\[6\]](#cite-id-4234zbxirs)​[\[5\]](#cite-id-odlg8mf2ze)​

## Bitwater

On October 23, 2026, Heatbit introduced Bitwater, a [mining](https://iq.wiki/wiki/mining) device designed to replace the heating element in a compatible electric water-heater tank. The product extends the company’s appliance-based approach from space heating to household hot water.[\[4\]](#cite-id-20wmaztlul)​[\[1\]](#cite-id-cpktiohgnb)​

Heatbit says Bitwater replaces a conventional resistance-wire element with 20 [Bitmain](https://iq.wiki/wiki/bitmain) BM1370 [mining](https://iq.wiki/wiki/mining) chips. The company advertises a maximum hashrate of 34 terahashes per second (TH/s), power draw of up to 600 watts, and mining efficiency starting at 12 joules per terahash. According to Heatbit, the chips’ waste heat warms the tank water, which also cools the chips; the company says this arrangement requires no fans and produces no fan noise.[\[8\]](#cite-id-8gykqqyvb2)​[\[1\]](#cite-id-cpktiohgnb)​[\[4\]](#cite-id-20wmaztlul)​

Heatbit describes Bitwater as designed for 30- to 80-gallon electric tanks in the United States and Canada with a compatible one-inch screw-in element port. The company lists models from A. O. Smith, Rheem, Bradford White, Whirlpool, and GE among compatible tanks. Heatbit says installation involves cutting power at the breaker, draining the tank, removing the existing element, and fitting Bitwater, without plumbing changes or a new circuit. The company says the unit uses a titanium anode rod to limit corrosion and that its water-contacting parts are lead-free and comply with the U.S. Safe Drinking Water Act. NSF/ANSI/CAN 372 addresses lead content in drinking-water system components and specifies lead-content limits and testing methodology; that standard concerns lead content, not lead-leaching criteria.[\[8\]](#cite-id-8gykqqyvb2)​[\[1\]](#cite-id-cpktiohgnb)​[\[9\]](#cite-id-p3bnwhopm4)​[\[10\]](#cite-id-y2czwjj13i)​

Heatbit says Bitwater draws up to 600 watts, compared with the 4,500-watt heating elements common in 240-volt American tanks. The company says it heats water more slowly and for longer periods, while a tank’s existing upper element can still provide backup when demand rises. Heatbit also says the lower operating temperature can reduce limescale buildup.[\[8\]](#cite-id-8gykqqyvb2)​[\[3\]](#cite-id-d1wdnsyd1a)​

Heatbit says a companion app displays water temperature, hashrate, and [mining](https://iq.wiki/wiki/mining) earnings. Owners can choose solo mining or a [mining pool](https://iq.wiki/wiki/mining-pool), with [Bitcoin](https://iq.wiki/wiki/bitcoin) proceeds sent to an address they control. Heatbit offered refundable preorders for its Genesis batch at $899 and said it expected the first units to ship in the first quarter of 2027; the company said later batches could cost up to $1,299.[\[8\]](#cite-id-8gykqqyvb2)​[\[1\]](#cite-id-cpktiohgnb)​[\[4\]](#cite-id-20wmaztlul)​

Heatbit said it tested Bitwater over the winter in households in New York and Florida, including homes with four and five residents. The company said water-heating costs remained the same when Bitwater replaced a previously used element.[\[3\]](#cite-id-d1wdnsyd1a)​[\[1\]](#cite-id-cpktiohgnb)​

## Mining and Decentralization

Both conventional resistance elements and [mining](https://iq.wiki/wiki/mining) chips convert nearly all the electricity they use into heat. In Bitwater, Heatbit’s mining chips use that heat to warm water.[\[1\]](#cite-id-cpktiohgnb)​[\[3\]](#cite-id-d1wdnsyd1a)​

Heatbit argues that household appliances could distribute [mining](https://iq.wiki/wiki/mining) among many homes instead of concentrating hashrate in industrial facilities. The company has contrasted an estimated 300 terawatt-hours of annual household water-heating electricity use with roughly 170 terawatt-hours consumed by the entire [Bitcoin](https://iq.wiki/wiki/bitcoin) network. The potential effect on mining decentralization would depend on household adoption and the resulting share of network hashrate; concentration matters because a [51% attack](https://iq.wiki/wiki/51percent-attack) can enable disruptions such as transaction reordering or censorship.[\[3\]](#cite-id-d1wdnsyd1a)​[\[1\]](#cite-id-cpktiohgnb)​[\[4\]](#cite-id-20wmaztlul)​

Reports described slowing [Bitcoin](https://iq.wiki/wiki/bitcoin) hashrate growth as large miners moved infrastructure toward artificial-intelligence workloads.[\[1\]](#cite-id-cpktiohgnb)​

Bitwater is part of a broader effort to reuse [mining](https://iq.wiki/wiki/mining) heat. MARA Holdings, formerly Marathon Digital Holdings, deployed two [Bitcoin](https://iq.wiki/wiki/bitcoin)-mining heat-recycling projects in Finland that supplied district-heating networks serving communities with nearly 80,000 residents. These projects illustrate heat reuse at district-heating scale, in contrast with Bitwater’s household water-heating use.[\[1\]](#cite-id-cpktiohgnb)​
