The Superheat H1 is the world’s first Bitcoin-mining water heater, a 50-gallon residential unit that replaces traditional resistive heating elements with ASIC mining chips. Priced at approximately $2,000 USD, it uses the waste heat from Bitcoin mining at 120 TH/s to heat your household water, potentially earning up to $1,000 per year in Bitcoin while consuming roughly the same energy as a standard electric water heater. It debuted at CES 2026 with early shipments beginning in March 2026.
What Is the Superheat H1?
The Superheat H1 is a 50-gallon residential water heater with a built-in Bitcoin mining ASIC. Where a traditional electric water heater uses resistive heating elements to convert electricity into heat, the H1 uses ASIC mining chips instead. The electricity flows through SHA-256 mining hardware, generates heat as a byproduct of computation, and that heat is transferred to the water in the tank through a heat exchanger.
The physics are identical. The economics are different. Both devices convert 100% of their electricity into heat (thermodynamics demands it). But the Superheat H1 also produces Bitcoin while it does so.
Unveiled at CES 2026 in January, the Superheat H1 generated significant press coverage as a novel application of the mining-as-heating concept. The company, Superheat (superheat.xyz), positions itself as “redefining energy infrastructure” by turning consumer appliances into compute-powered thermal systems.
How Bitcoin Water Heating Works
The concept behind Bitcoin-powered water heating is an extension of the same principle that drives Bitcoin space heaters: every watt consumed by an ASIC chip becomes a watt of heat. In a space heater, that heat warms the air. In a water heater, that heat warms water.
The Superheat H1 architecture works as follows:
- ASIC chips mine Bitcoin: Custom mining hardware inside the unit performs SHA-256 computations continuously, drawing power from the home’s electrical system.
- Heat generation: The ASIC chips produce heat as a natural byproduct of computation, exactly like every mining rig on the planet.
- Heat transfer: Instead of exhausting this heat into the air, a heat exchanger captures it and transfers it into the 50-gallon water tank.
- Water heating: The stored water reaches and maintains the target temperature, ready for showers, laundry, dishwashing, and other household use.
- Bitcoin accumulation: Simultaneously, the mining rewards are pooled and credited to the owner’s account, tracked via an app and web console.
The result is a water heater that does everything a traditional electric water heater does, with the same energy consumption, but also generates a Bitcoin revenue stream.

A note on the specs: Superheat has not published complete technical documentation as of this writing. The hashrate, power consumption, and earnings figures come from the company’s CES 2026 presentation and press materials. We have not independently verified these claims. The ASIC chip model used has not been disclosed publicly.
At 3.3 kW and 120 TH/s, the implied efficiency is approximately 27.5 W/TH. For context, a current-generation Antminer S21 achieves roughly 17.5 W/TH. The H1 is less efficient per terahash, but this is expected given the thermal management constraints of operating inside a water tank and the priority on matching standard water heater power consumption.
Why Water Heating Changes the Game
This is where the Superheat H1 addresses the single biggest weakness of every Bitcoin space heater on the market, including the ones we sell at D-Central.
The Seasonality Problem
Space heating is seasonal. In most of North America, you need supplemental heat for 4 to 7 months per year. During summer, running a space heater is counterproductive because you are adding heat to a home you are actively cooling with air conditioning. This means every Bitcoin space heater sits idle, or runs at a net loss, for nearly half the year.
Water heating is year-round. You take hot showers in January and July. You run the dishwasher and washing machine twelve months a year. According to the U.S. Department of Energy, domestic water heating accounts for approximately 20% of the average home’s energy consumption, making it the second-largest energy expense after space heating and cooling.
Year-Round Utility Means Better ROI
A Bitcoin miner that produces useful heat 365 days a year has a fundamentally different economic profile than one that is useful for only 150-200 days. The electricity cost remains a “sunk cost” for water heating year-round because you need hot water regardless. Every Bitcoin mined is pure economic surplus, not offset by the opportunity cost of cooling your home in summer.
This is the core insight that makes the Superheat H1 conceptually compelling: it eliminates the seasonal penalty that limits the ROI of space-heater miners.
The Numbers
Consider a typical household water heating scenario:
- Average annual cost of electric water heating in the US: $400-$600/year
- Superheat H1 annual electricity cost at $0.12/kWh: Approximately $3,470/year (3.3 kW x 24 hours x 365 days x $0.12/kWh)
- Standard 50-gallon electric water heater annual cost: Similar range, depending on usage patterns and standby losses
- Superheat’s claimed Bitcoin revenue: Up to $1,000/year
Wait. Those electricity numbers deserve scrutiny. A standard 50-gallon electric water heater does not run 24/7 at full power. It heats water on demand and maintains temperature, cycling on and off. Actual energy consumption is typically 3,000-4,500 kWh per year, depending on household usage, not the theoretical maximum of 28,908 kWh that continuous 3.3 kW operation would imply.
If the Superheat H1 runs its ASIC miner continuously at 3.3 kW (which is necessary to maintain meaningful hashrate), it would consume significantly more electricity than a traditional water heater that only activates when the tank temperature drops. Superheat claims the H1 “uses about the same amount of energy as a standard electric water heater,” but the mechanism by which 120 TH/s of continuous mining consumes the same energy as intermittent resistive heating needs independent verification.
The more likely scenario: the mining hardware runs continuously, but the net cost is offset by Bitcoin revenue. The claim of “offsetting up to 80% of electricity and water costs” probably factors in Bitcoin earnings as a credit, not a pure energy-equivalence claim.
Current Status: Can You Buy a Superheat H1?
As of February 2026:
- CES 2026 world premiere: January 2026 (completed)
- Early shipments: Superheat states March 2026
- Global rollout: Later in 2026
- Price: ~$2,000 USD
- How to order: Through superheat.xyz
Some reports indicate early units may have shipped as early as late 2025 to select customers, but the broader consumer launch appears to be March 2026. As with any hardware product launching from a startup, we recommend verifying current availability directly on their website before ordering.
Importantly: the Superheat H1 requires professional plumbing installation, similar to any water heater replacement. This is not a plug-and-play device like a Bitcoin space heater. You will likely need a licensed plumber, and potentially an electrician to verify adequate electrical service (3.3 kW at 240V is a standard water heater circuit, but confirm your panel can support it).
How This Fits D-Central’s Vision
At D-Central, we have been pioneering the mining-as-heating concept since before it was a CES headline. Our Bitcoin Space Heaters take Antminer hardware, from the S9 through the S19 and beyond, silence it with premium cooling solutions, enclose it in custom cases, and deliver it as a plug-and-play heating-plus-mining solution. We have shipped thousands of these units from our shop in Laval, Quebec.
The Superheat H1 validates the core thesis we have built our business around: waste heat from Bitcoin mining is not waste at all. It is a resource. Every home has heating needs, and every watt of electricity consumed by a miner produces exactly the same heat as a watt consumed by a resistive element. The only difference is that the miner also produces Bitcoin.
Water heating is the logical next frontier. We are watching the Superheat H1 closely because it addresses the seasonality problem that limits the utility of space-heater miners in warmer months. If the product delivers on its promises, it could complement space heater mining perfectly: run your Bitcoin space heater during the cold months, and let a Bitcoin water heater handle year-round mining duty.
The mining-as-heating ecosystem is growing. That is good for Bitcoin decentralization, good for home miners, and good for anyone who believes that hashrate belongs in homes, not just in industrial warehouses.
What We Are Watching: Concerns and Open Questions
As mining hardware experts who repair ASICs every day, we have some questions and concerns about the Superheat H1 that need answers before we can give it a full endorsement:
Long-Term Reliability
ASIC chips are robust, but they are designed to operate in air-cooled or immersion-cooled environments with controlled conditions. Operating inside a water heater introduces unique thermal cycling, humidity, and potential condensation challenges. Superheat claims a 10-year lifespan, but no one has run this device for 10 years. Traditional water heaters last 8-12 years on average. We want to see real-world reliability data before making longevity claims.
Repairability
When an ASIC chip fails in a standard miner, you pull the hashboard, diagnose the fault, and replace the component. The repair process is well-understood across thousands of repair shops worldwide. What happens when an ASIC chip fails inside a sealed water heater? Can you access the mining hardware without draining the tank? Is the mining module modular and replaceable? Or does a chip failure turn your $2,000 mining water heater into a $2,000 traditional water heater? These are critical questions for a device with a claimed 10-year lifespan.
Plumbing Integration and Code Compliance
Water heaters are subject to local building codes, plumbing codes, and potentially electrical codes. A device that combines high-power computing with potable water storage is novel from a regulatory perspective. We want to see UL listing, NSF certification for potable water contact, and confirmation that the device meets code requirements in major jurisdictions. Superheat has not publicly shared certification details as of this writing.
The Electricity Cost Reality
A standard electric water heater uses 3,000-4,500 kWh per year because it cycles on and off. If the Superheat H1 runs its ASIC miner continuously at 3.3 kW, annual consumption could exceed 28,000 kWh, roughly 6-9x more than a traditional unit. The Bitcoin revenue needs to more than offset this increased electricity consumption for the economics to work. At $0.12/kWh, continuous operation costs ~$3,470/year. If the device earns $1,000/year in Bitcoin, the net cost of water heating is ~$2,470/year, significantly more than a traditional water heater’s $400-$600/year.
The economics only work if you frame it as “I am running a 120 TH/s Bitcoin miner that happens to produce free hot water” rather than “I have a water heater that earns Bitcoin.” The distinction matters for setting expectations.
Noise
Water heaters are typically silent. ASIC miners are not. Superheat describes the H1 as featuring “quiet operation,” but has not published decibel ratings. If the device has fans for ASIC cooling (even if the primary cooling is water-based), the noise profile could be a concern for installation in living spaces. Most water heaters sit in basements, garages, or utility closets where noise is less of an issue, but this still needs to be quantified.
Mining Hardware Obsolescence
Bitcoin mining hardware becomes less competitive as network difficulty increases and newer, more efficient chips are released. A traditional water heater lasts 10 years because resistive heating elements do not become obsolete. ASIC mining chips absolutely do. The 120 TH/s that earns $1,000/year in 2026 may earn significantly less in 2030. Is the mining module upgradeable? This is a critical question for a 10-year appliance.
Frequently Asked Questions
Is the Superheat H1 available for purchase right now?
The Superheat H1 debuted at CES 2026 in January, with early shipments planned for March 2026 and a broader global rollout later in 2026. Check superheat.xyz for current availability and ordering information. Some early units may have shipped to select customers in late 2025.
Can I install a Superheat H1 myself?
The Superheat H1 requires the same plumbing connections as a standard 50-gallon electric water heater, plus a 240V electrical circuit. If you are comfortable replacing a water heater, you can likely handle the installation. However, most jurisdictions require a licensed plumber for water heater installations, and we recommend professional installation to ensure code compliance and warranty protection.
How does the Superheat H1 compare to a Bitcoin space heater?
A Bitcoin space heater warms the air in a room and is most useful during cold months (4-7 months in most climates). A Bitcoin water heater warms water, which is needed year-round. The two are complementary rather than competitive. The ideal setup for a Bitcoin home miner might include both: a space heater for winter heating and a water heater for year-round hot water.
Will the mining hardware in the Superheat H1 become obsolete?
All mining hardware eventually becomes less competitive as network difficulty increases and newer chips are released. The key question is whether the Superheat H1’s mining module is upgradeable. Superheat claims a 10-year lifespan, but the mining economics in year 10 will likely differ substantially from year 1. However, even as mining revenue decreases, the device still functions as a water heater, so it never becomes completely worthless.
Does the Superheat H1 work with solar panels?
In principle, yes. The Superheat H1 draws approximately 3.3 kW, which is within the output range of a modest residential solar array. Pairing a Bitcoin mining water heater with solar power would dramatically improve the economics by reducing or eliminating the electricity cost. Superheat has referenced renewable energy integration in their materials, but specific solar compatibility details have not been published.
The Future of Dual-Purpose Mining
The Superheat H1 represents a meaningful evolution in the mining-as-heating concept. Moving from space heating to water heating solves the seasonality problem and makes the economic case for home mining substantially stronger.
But let us keep perspective. This is a first-generation product from a startup. The device needs to prove itself in real-world installations over real-world timescales. Questions about reliability, repairability, regulatory compliance, and actual electricity consumption need answers that only time and independent testing can provide.
What excites us at D-Central is not any single product. It is the trend. The idea that Bitcoin mining hardware belongs in homes, doing useful work, generating useful heat, and distributing hashrate away from centralized facilities is exactly the vision we have been building toward since 2016. Our Bitcoin Space Heaters pioneered this approach. Products like the Superheat H1 expand the addressable market and validate the thesis.
The future of home mining is not a single device. It is an ecosystem: space heaters for cold months, water heaters for year-round duty, pool heaters for summer, radiant floor systems, hot tubs. Every thermal load in your home is a potential Bitcoin miner. Every watt of heat you need is a watt that could be mining.
We are watching. We are researching. And if the time is right, D-Central will bring our Mining Hacker approach to water heating too: open firmware, repairable hardware, pool freedom, and no compromises on sovereignty.
In the meantime, heating season is here. If you want to start mining Bitcoin with your home heating today, not next March, check out our Bitcoin Space Heaters. They ship from Canada, run on open firmware, and are built to be repaired, not replaced.
