Heatbit launches Bitwater, a Bitcoin-mining water heater element priced at $899
Heatbit has introduced Bitwater, a Bitcoin-mining heating element designed to fit into existing electric water heaters in the U.S. and Canada. The first preorder batch is priced at $899, with shipments scheduled for the first quarter of 2027. The company says the unit can deliver up to 34 TH/s at 600 watts and pitches it with a simple line: the same heat, the same electricity, plus Bitcoin. The product replaces the lower heating element in a standard electric tank and uses 20 Bitmain BM1370 chips to transfer mining heat directly into the water. Heatbit says the upper element and thermostat remain in place as backup, and installation should take 30 to 45 minutes without plumbing changes or a new circuit. A $99 live video installation guide will also be offered after shipping. The economics are less straightforward. Based on the figures cited in the source article, Bitwater could generate about $1.25 per day at full speed, or roughly $365 per year at an 80% runtime. That implies a payback period of about two to 3.6 years depending on pricing and usage, while the warranty lasts only one year. The article also notes that if the device is treated purely as a miner, daily electricity costs would exceed mining revenue, making the value proposition heavily dependent on the assumption that the power would have been used for water heating anyway.
