Antminer S21 Hydro (Bitcoin Heating)
Bitcoin Appliances
The Bitmain Antminer S21 Hydro is a water-cooled Bitcoin ASIC miner designed for liquid heat recovery applications. Unlike air-cooled models, it pumps hot water (up to 60°C) through a heat exchanger, making it ideal for district heating, swimming pool heating, greenhouse climate control, and industrial hot water systems powered by Bitcoin mining. At 335 TH/s with 5360W power draw, it delivers substantial heat output. Several European and North American deployments use the S21 Hydro to heat buildings while mining Bitcoin commercially.
