American startup Superheat introduced a household water heater with cryptocurrency mining function at CES 2026. The development aims to increase energy efficiency by reusing heat from computing processes, CNet reported.
The Superheat H1 model combines a 190 liter storage boiler and a dedicated ASIC computer for Bitcoin mining. The heat generated by the chip during calculation will be sent to the heat exchanger and used to heat water.
According to the developers, the owner's electricity costs are comparable to the costs of a conventional electric boiler, while mining income can partially or fully offset the cost of water heating. The price of the device is about 2000 USD, 30–40% higher than traditional similar devices.
At the current stage, the system only supports Bitcoin mining, but the company is considering using this technology more widely. Superheat COO Julie Xu said such devices could eventually be used for distributed cloud computing and AI. The concept involves connecting thousands of household devices into a decentralized computer network that can reduce the load on large data centers.
