Obelisk DCR1
Heater-Class Miner
At 500W, this miner outputs approximately 1706 BTU/hr of heat — equivalent to a standard electric space heater. Every watt consumed by an ASIC miner is converted to heat with 100% efficiency, making it a space heater that also mines Bitcoin.
During heating season, miner heat can offset part of the heat a room would otherwise need from another electric heater. The economics depend on your electricity rate, room heat demand, BTC price, network difficulty, and noise constraints.

Home Mining Assessment
The Obelisk DCR1 is a Blake256r14 cryptocurrency miner manufactured by Obelisk. It delivers a hashrate of 1.2 TH/s with a power consumption of 500W, achieving an efficiency of 416.7 J/TH.
Weighs 9000 kg, measures 200 x 200 x 360mm.
With a home mining score of 34/100, this miner is best suited for dedicated mining spaces for residential use. It produces 1706 BTU/h of heat output, making it suitable for supplemental space heating.
At 416.7 J/TH, the Obelisk DCR1 sits in the legacy efficiency tier, so it is most economical run as a space heater or for hobby and learning setups rather than for pure profit.
Its waste heat (around 1706 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
