The device integrates ASIC miners with a 50-gallon water heater, using the same energy as standard models while potentially offsetting heating costs through mining revenue.
A Bitcoin mining water heater was featured at the CES 2026 show floor, combining ASIC (Application-Specific Integrated Circuit) Bitcoin miners with a 50-gallon water heater. The device consumes the same amount of energy as a standard electric water heater while simultaneously mining Bitcoin. According to the presentation, mining revenue generated by the device could fully offset water-heating expenses, offering a dual-purpose solution for households.
