Goldshell KD6
Professional-Grade Miner
This miner draws 2,630W 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 2,630W, this miner outputs approximately 8974 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 | $0.80 | $4.42 | $-3.61 |
| Weekly | $5.63 | $30.93 | $-25.30 |
| Monthly | $24.11 | $132.55 | $-108.44 |
| Yearly | $293.35 | $1,612.72 | $-1,319.37 |
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 KD6 is a Blake2s cryptocurrency miner manufactured by Goldshell. It delivers a hashrate of 29.2 TH/s with a power consumption of 2630W, achieving an efficiency of 90.1 J/TH.
Weighs 8500 kg, measures 200 x 264 x 290mm.
With a home mining score of 22/100, this miner is best suited for dedicated mining spaces for residential use. It produces 8974 BTU/h of heat output, making it effective for supplemental space heating.
At 90.1 J/TH, the Goldshell KD6 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 8974 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.

Frequently Asked Questions
What are the current mining economics for the Goldshell KD6?
At $0.07/kWh, the Goldshell KD6 currently shows an estimated daily net cost of $3.61 before pool fees and hardware cost. Lower electricity rates, network changes, BTC price changes, or useful heat recovery can change the result.
Can I mine Bitcoin at home with the Goldshell KD6?
The Goldshell KD6 has a home mining score of 22/100. With 0 dB noise and 2,630W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the Goldshell KD6 heat my home?
The Goldshell KD6 outputs approximately 8974 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 Goldshell KD6 need?
The Goldshell KD6 draws 2,630W of power. You need a power supply rated for at least 2,893W 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 the miner and wiring.
