At the CES 2026 exhibition, the Superheat startup introduced the Superheat H1 water heater, which simultaneously warms water and mines bitcoins. The apparatus utilizes heat from mining for household needs.
At CES 2026, the US company Superheat demonstrated an innovative domestic water heater that permits cryptocurrency mining. The main premise involves leveraging the warmth generated during the operation of computational systems to boost energy efficiency, as reported by CNet.
The Superheat H1 model is a device that combines a large 190-liter hot water tank and a dedicated computer for mining the Bitcoin cryptocurrency. When this computer is running, it produces heat. This heat is directed into a special system that heats the water in the tank. In this manner, the computer’s work aids in warming the water for home utilization.
The unit’s cost is around \$2,000, which is 30-40% greater than the price of conventional counterparts. Nevertheless, the developers contend that this expenditure recoups itself in approximately two years. By their calculations, an owner of a Superheat H1 might offset up to 80% of electricity and hot water expenses through mining profits. On average, the device yields about \$1,000 in passive income yearly. Furthermore, the boiler’s service life is projected at 10 years—on par with standard household water heaters.
The financial benefit becomes even more significant with widespread adoption. For instance, installing these units in a residential complex of 700 apartments could generate up to \$980,000 in annual revenue. It is noteworthy that the Superheat H1’s power consumption stays comparable to a regular electric water heater—all extra advantage is gained via heat reuse.
At this present stage, the device supports only Bitcoin mining, but the firm is already considering enhancing its functionality. Superheat’s Chief Operating Officer, Julie Xu, shared intentions to employ similar setups for distributed cloud computing and artificial intelligence tasks. The concept anticipates linking thousands of household installations into a decentralized computational network that could lessen the strain on major data centers.
Thus, the Superheat H1 showcases a fundamentally new method for energy efficiency: household appliances cease being mere energy consumers and transform into revenue sources, effectively employing resources previously viewed as byproducts of the technological process.
