Superheat Bitcoin-Mining Water Heater

Your water heater has been costing you money for decades, but Superheat thinks it is time for it to start paying you back. The H1 is a smart water heater that mines Bitcoin in the background during everyday use, redirecting the heat its processors generate to warm your water, so the energy that was always going to be spent is now pulling double-duty. Earnings can offset up to 80% of your electricity and water costs, generating up to $1,000 a year in BTC, all managed through a companion app that tracks usage and allows withdrawals from anywhere in the world. Debuted at CES 2026, the H1 works for a single household or scales across an entire commercial property, turning one of the most overlooked appliances into a passive income source.
