Holic H22
Professional-Grade Miner
This miner draws 1,700W 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 1,700W, this miner outputs approximately 5800 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 | $0.78 | $2.86 | $-2.08 |

| Monthly | $23.35 | $85.68 | $-62.33 |
| Yearly | $284.06 | $1,042.44 | $-758.38 |
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 Holic H22 is a SHA-256 cryptocurrency miner manufactured by Holic. It delivers a hashrate of 22 TH/s with a power consumption of 1700W, achieving an efficiency of 77.3 J/TH.
Measures 175 x 189 x 420mm.
With a home mining score of 28/100, this miner is best suited for dedicated mining spaces for residential use. It produces 5800 BTU/h of heat output, making it effective for supplemental space heating.
At 77.3 J/TH, the Holic H22 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 5800 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 Holic H22?
At $0.07/kWh, the Holic H22 currently shows an estimated daily net cost of $2.08 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 Holic H22?
The Holic H22 has a home mining score of 28/100. With 0 dB noise and 1,700W power draw, it may require a dedicated space like a garage, basement, or outdoor enclosure. Consider noise insulation and proper ventilation.
Can the Holic H22 heat my home?
The Holic H22 outputs approximately 5800 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 Holic H22 need?
The Holic H22 draws 1,700W of power. You need a power supply rated for at least 1,870W 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.
