Goldshell CK5
Professional-Grade Miner
This miner draws 2,400W 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 2,400W, this miner outputs approximately 8189 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.
Profitability Calculator
| Period | Revenue | Electricity Cost | Profit |
|---|---|---|---|
| Daily | $0.33 | $4.03 | $-3.70 |
| Weekly | $2.31 | $28.22 | $-25.92 |
| Monthly | $9.89 | $120.96 | $-111.07 |
| Yearly | $120.28 | $1,471.68 | $-1,351.40 |
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.

Home Mining Assessment
The Goldshell CK5 is a Eaglesong cryptocurrency miner manufactured by Goldshell. It delivers a hashrate of 12 TH/s with a power consumption of 2400W, achieving an efficiency of 200 J/TH.
Weighs 8500 kg, measures 264 x 200 x 290mm.
With a home mining score of 26/100, this miner is best suited for dedicated mining spaces for residential use. It produces 8189 BTU/h of heat output, making it effective for supplemental space heating.
At 200 J/TH, the Goldshell CK5 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 8189 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
