Heatbit unveils Bitwater, a water heater that mines Bitcoin

What happened

The Delaware-based company has launched Bitwater , a residential heating element that warms water and mines Bitcoin at the same time.

Preorders opened on October 22, 2026, and first shipments are expected in the first quarter of 2027. Instead of a plain resistive coil, the element runs SHA-256 (cryptographic hash function) hashing, the cryptographic puzzle-solving that secures the Bitcoin network.

Bitwater's dual-functionality could decentralize Bitcoin mining, potentially increasing network security while offering homeowners energy cost offsets. 22, 2026 Your water heater spends its whole life turning electricity into heat.

Heatbit thinks it should also be earning Bitcoin while it does that. It is built to fit into the electric water tanks people already own.

What Bitwater actually does Bitwater swaps in as the heating element inside an existing electric water tank. The waste heat from that computation then warms the water.

Heatbit says the device delivers up to 34 TH/s of hashing power. TH/s stands for terahashes per second, a measure of how many guesses a machine makes at the Bitcoin puzzle each second.
