Obelisk SC1 Immersion
Immersion-Cooled Miner
This miner is designed to operate fully submerged in a dielectric (non-conductive) cooling fluid. Unlike hydro miners that circulate liquid through internal channels, immersion miners have their entire board and chips bathed in engineered coolant inside a specialized tank.
Immersion cooling is the most effective thermal management available for ASIC miners. It eliminates all fan noise (completely silent operation), removes dust and humidity as failure factors, enables maximum overclocking potential, and dramatically extends hardware lifespan by maintaining perfectly even chip temperatures.
The trade-off is infrastructure: immersion requires a tank, dielectric fluid (typically engineered hydrocarbon or synthetic), and a heat exchanger. It is the gold standard for professional mining farms and serious home miners who want maximum performance with zero noise.
Professional-Grade Miner
This miner draws 1,600W and produces 75+ dB of noise — it is designed for dedicated mining environments, not living spaces. Professional-grade miners deliver the highest hashrate and revenue per unit but require proper infrastructure: a 240V circuit, adequate ventilation or exhaust ducting, and a space where noise is not a concern (garage, basement, warehouse, or outdoor enclosure).
For home miners looking for a quieter alternative, consider our Bitcoin Space Heater builds or explore open-source miners like the Bitaxe that are purpose-built for residential environments.
Heater-Class Miner
At 1,600W, this miner outputs approximately 5459 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, the electricity cost of running this miner replaces your heating bill — and you earn Bitcoin on top. In cold climates like Canada, this dual-purpose approach can dramatically improve mining economics. D-Central offers purpose-built Bitcoin Space Heater editions with noise reduction, duct adapters, and heater-mode firmware for seamless home integration.
Profitability Calculator
| Period | Revenue | Electricity Cost | Profit |
|---|---|---|---|
| Daily | $0.07 | $2.69 | $-2.62 |
| Weekly | $0.49 | $18.82 | $-18.32 |
| Monthly | $2.12 | $80.64 | $-78.52 |
| Yearly | $25.78 | $981.12 | $-955.34 |
Heating offset estimates the value of heat replacing an electric space heater during heating season (~6 months/year in Canada). Actual savings depend on your heating setup and climate.

Frequently Asked Questions
Is the Obelisk SC1 Immersion profitable?
At $0.07/kWh, the Obelisk SC1 Immersion currently operates at a daily loss of $2.62. However, profitability can improve with lower electricity rates or rising BTC prices. If used as a space heater, the heating offset may make it economically viable.
Can I mine Bitcoin at home with the Obelisk SC1 Immersion?
The Obelisk SC1 Immersion has a home mining score of 28/100. With 0 dB noise and 1,600W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the Obelisk SC1 Immersion heat my home?
The Obelisk SC1 Immersion outputs approximately 5459 BTU/hr of heat. For reference, a typical space heater produces 5,000-5,500 BTU/hr. All electrical energy consumed by the miner is converted to heat, making it 100% efficient as a heater. D-Central offers Bitcoin Space Heater builds designed specifically for home heating integration.
What power supply does the Obelisk SC1 Immersion need?
The Obelisk SC1 Immersion draws 1,600W of power. You need a power supply rated for at least 1,760W with appropriate voltage (200-240V AC). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect your investment.
