Heatbit has released Bitwater, which is a water heater component equipped with 20 Bitcoin mining chips and can be installed in existing electric water tanks in the United States and Canada.
This component can provide up to 34 TH /s of computing power, with a maximum power consumption of 600 watts; the initial pre-sale price is $899, and subsequent batches will have a maximum price of $1,299.
Heatbit positions it as a decentralized method of Bitcoin mining, and indicates that the electricity consumption for household hot water heating is even higher than that of the entire Bitcoin network.
This company produces space heaters equipped with built-in Bitcoin miners. On Thursday, Heatbit stated in a tweet that the company has launched a water heater component that mines Bitcoin while heating water.
This component, named Bitwater, replaces the resistance wire in a standard electric water heater with 20 Bitmain's BM1370 chips. As a result, the heat emitted by these chips is used to heat the water. Heatbit writes: "The same amount of heat, the same amount of electricity, plus Bitcoin," and adds that "electricity is already used for heating water anyway."
Heatbit wrote in a tweet: "Introducing Bitwater: This water heater component can be used to mine Bitcoin. It can be installed into the electric water heater you already have. Physically decentralized mining will continue to operate regardless of anything. It heats water and mines Bitcoin – all in the same tank."
This component uses 20 Bitmain BM1370 chips, with a rated computing power of up to 34 TH /s and a maximum power consumption of 600 watts. The energy efficiency is 12 joules per TH. The company claims that water is used to cool the chips, so there are no fans and therefore no noise.
Heatbit is described as a task that can be completed independently: first, turn off the circuit breaker, empty the water tank, remove the old components, and then install the Bitwater using the included wrench. The company stated in subsequent tweets that it is suitable for the standard one-inch interfaces of electric water tanks commonly found in the United States and Canada, ranging from 30 to 80 gallons, including models produced by A. O. Smith, Rheem, Bradford White, Whirlpool, and GE. No modifications to the pipes are required, nor is a new electrical circuit needed.
The power consumption of Bitwater can reach up to 600 watts, which is significantly lower than the common 4,500 watt components found in American water tanks. Heatbit explains that the latter types heat up quickly and then shut off, whereas Bitwater heats more slowly but operates for a longer time. When demand surges, the existing upper components of the water tank can still be used as backups.
Users can view water temperature, computing power, and earnings within the application, and they can switch between mining independently or joining a mining pool. The Bitcoin mined will be sent to the user-controlled wallet address.
The first production batch, which is what Heatbit refers to as “Genesis batch”, has a pre-sale price of $899; subsequent batches will have a maximum price of $1,299. Refundable reservations are expected to be shipped in the first quarter of 2027. Heatbit indicates that the company has tested this component throughout the winter in four- and five-person households in New York and Florida, and also announces that products suitable for gas water heater homes will be launched in the future.
Heatbit has not yet announced its own revenue estimates. Instead, the company cited a reply from Grok's chatbot on xAI, stating that the daily revenue is approximately $1 to $1.25, and added that "estimates are not guarantees." This is consistent with Decrypt's own calculations. According to Hashrate Index's data, at the current rate of $36.73 per hashprice per PH, a device running at full capacity for 34 TH per PH could mine about $1.25 in Bitcoin per day, or approximately $455 per year. Heatbit mentioned that this component is designed to operate for over 80% of the time, and the revenue will fluctuate with the price of Bitcoin and the difficulty of mining across the network.
Heatbit's advocacy for home mining
Heatbit is positioning Bitwater as a way to distribute Bitcoin mining among households. The company states that households around the world consume approximately 300 terawatt-hours of electricity each year for heating hot water, whereas the entire Bitcoin network consumes about 170 terawatt-hours.
Heatbit writes: 'Public miners are fleeing to AI and selling tokens to pay the salaries of Wall Street and CEO.' 'Family miners are not under the control of anyone.'
Large listed mining companies have been shifting towards AI. Bernstein previously stated this year that Bitcoin mining companies have signed 17 transactions totaling over $110 billion in two years, outsourcing approximately 6 gigawatts of electricity to companies including Google, Amazon, Microsoft, Nvidia, and CoreWeave. The firm expects the revenue of the mining companies it covers, AI, to grow from $1.2 billion in 2026 to $10.7 billion by 2030, and noted that the planned power capacity of these mining companies exceeds 27 gigawatts, making them important power suppliers in the AI boom.
However, the operating methods of these two businesses are different. Bitcoin miners can shut down to relieve the pressure on the power grid, whereas the AI data centers require power supply around the clock. In March 2025, Shanon Squires from Compass Mining stated to Decrypt: “As Bitcoin miners, we can be interrupted, whereas traditional data centers need to remain operational 100% of the time.”
The company's first product was a space heater with a built-in miner, which was priced at nearly $700 in 2023. Founder Alex Busarov stated at that time to Decrypt, no matter how the economics of mining change, this product would always be able to make some money because the heat it generates replaces that of traditional heaters. “Dyson won’t make you money. This one will,” he said.
