With the colder weather incoming we are getting back on the topic of using crypto miners to heat our homes and take advantage of the excess heat that these devices produce while mining your favourite cryptocurrency. The Antminer S9 and or L3-based ASIC Space Heaters are still nice and all, especially if you already own some of those ASIC devices or want to get one pretty cheap, but things are moving further and we are starting to see designs based on newer ASIC hardware such as the BitChimney Space Heater that is based on a single Antminer S19 hashboard and capable of running on both 120V and 240V (US and Europe compatible). A silent and efficient device by Altair Tech that hashes nicely, stays silent and produces enough heat to also help you with heating at home… and it even looks quite nice with a cool 3D printed enclosure. Bit-Chimney Single Hashboard Space Heater is WiFi ready, runs on 110V-240V input Voltage, utilizes the Loki Kit by Pivotal Pleb Tech, runs at 23 TH/s at 750W or 30 TH/s at 1000W and at up to 60 Db noise level, so pretty silent. The first batch is expected to start shipping on October 30th priced at $699 USD. And if you are feeling more DIY-ish you might want to start tinkering around an S19 and make your own design as well.
