Mining in the Bathroom: Superheat Unveils Revolutionary Bitcoin Water Heater at CES 2026

Superheat announced at CES 2026 the H1 water heater with a built-in ASIC miner for Bitcoin, which uses the heat from computations to heat water, while simultaneously mining BTC and partially offsetting utility costs.

How Does It Work?

The device is based on a standard 50-gallon (approximately 189-liter) water tank, on which a specialized computer with ASIC chips for Bitcoin mining is installed. During intensive mathematical calculations (hashing), the miner generates heat, which is typically wasted in traditional data centers. Here, this heat is directed towards heating water for showers, dishwashing, or other household needs. Users can monitor water temperature and mining performance through a mobile app.

According to Superheat representatives, the device consumes as much energy as a regular electric water heater but efficiently repurposes waste heat, making the process more environmentally friendly. It is expected that Bitcoin mining (with the current price around $90,000 per coin) could generate up to $1000 per year, offsetting up to 80% of electricity and water costs.

Price, Availability and Environmental Impact

The cost of the Superheat H1 is around $2000, which is slightly more expensive than standard water heaters, but the company claims the device will "pay for itself" through mining profits. The announcement took place at CES 2026, but the exact market release date has not been announced yet. The device is suitable for homes, apartments, and commercial buildings.

From an environmental perspective, this technology helps address the issue of energy consumption in the crypto industry and AI. Instead of building massive data centers with high energy and water usage for cooling, Superheat offers a decentralized approach where heat is used beneficially, reducing the overall carbon footprint.

Future Plans

Superheat is not stopping at Bitcoin. In the future, the company plans to integrate the ability to combine hundreds or thousands of such water heaters into a distributed computing network. This will allow them to be used for processing requests, executing neural network tasks, and cloud computing without the need for new data centers. As noted by Julie Hu, Superheat's head of operations, the ultimate goal is to turn household appliances into decentralized computing power, where large AI companies will pay users for using their devices.

This idea has already attracted attention in the crypto community: on Reddit and Instagram, users are discussing the device's potential, calling it "mining in the bathroom," which could revolutionize both crypto and energy.
