This $2,000 Bitcoin mining water heater can pay for itself by slashing your energy bills, company claims — can rake in $1,000 a year in BTC, offset 80% of electricity and water costs

Superheat was at CES 2026 to showcase what it describes as “a water heater that pays for itself.” The new Superheat H1 is a $2,000 water heater that warms up your H2O using waste-heat from its built-in Bitcoin mining ASIC hardware, rather than an immersed resistive heating element.

It is claimed that owners of a Superheat H1 can “offset up to 80% of electricity and water costs” with earnings from cryptomining. Superheat extrapolates these numbers to suggest that a 700-apartment community could raise “up to $980,000 yearly earnings.”

The infographic above shows that a Superheat H1 can earn $1,000 in passive income per year. Therefore, your initial hardware investment should be entirely paid-off in two years, while it reduces your water heater energy spend by 80%. The H1 has a predicted service life of 10 years, very similar to a regular domestic boiler.

Waste not, want not

Cooling data centers that run demanding workloads like cryptocurrency mining is a notoriously expensive business. It is estimated that cooling is the second most costly activity after actually powering the systems to chew through the tasks central to their existence.

But what if the ‘waste’ heat became a benefit? Indeed, some businesses, and most households, spend a lot of their energy budget heating water, for washing and heating systems, and so on, and get nothing else back except a hefty utility bill.

Enter the Superheat H1 with its “dual-value operation.” It requires roughly the same amount of energy as a regular electric water heater, according to the maker. Moreover, it is claimed to be scalable beyond homes, for apartment blocks, hotels, and so on.

“Heat is one of the world’s most overlooked resources,” said Andrew Geng, Co-Founder and CTO of Superheat. “The H1 proves that home appliances can create real economic and environmental value. As we expand into distributed AI and cloud computing, Superheat will redefine how buildings produce, reuse, and monetize heat.”

Bitcoin pricing is rather volatile. In Q3 last year, it nudged over $125,000, but 1BTC is currently valued at around $91,000. Superheat H1 owners should benefit from a higher Bitcoin valuation, but no one really knows which direction, nor how high or low BTC could go in 2026. CNBC recently measured investor and analyst predictions and estimated that Bitcoin valuations of between $75,000 and $225,000 would be seen this year.

Owning a Superheat H1 might be yet another reason for not being able to tune out from watching information feeds and stressing about trends, charts, and valuations. Can I heat water with a heatsink on my forehead?
