colengine P2
Professional-Grade Miner
This miner draws 1,458W and produces 80 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 1,458W, this miner outputs approximately 4975 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.

| Period | Revenue | Electricity Cost | Profit |
|---|---|---|---|
| Daily | $0.00 | $2.45 | $-2.45 |
| Weekly | $0.01 | $17.15 | $-17.14 |
| Monthly | $0.03 | $73.48 | $-73.45 |
| Yearly | $0.38 | $894.05 | $-893.67 |
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 colengine P2 is a Blake3 cryptocurrency miner manufactured by colengine. It delivers a hashrate of 38 GH/s with a power consumption of 1458W, achieving an efficiency of 38368.4 J/TH.
Operates at 80 dB noise level, weighs 14.75 kg, measures 361*134*271mm.
With a home mining score of 38/100, this miner is best suited for dedicated mining spaces for residential use. It produces 4975 BTU/h of heat output, making it suitable for supplemental space heating.
At 38368.4 J/TH, the colengine P2 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 4975 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 colengine P2?
At $0.07/kWh, the colengine P2 currently shows an estimated daily net cost of $2.45 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 colengine P2?
The colengine P2 has a home mining score of 38/100. With 80 dB noise and 1,458W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the colengine P2 heat my home?
The colengine P2 outputs approximately 4975 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 colengine P2 need?
The colengine P2 draws 1,458W of power. You need a power supply rated for at least 1,604W 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.
