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.
Solo Mining Estimate
Solo mining is a lottery. There is no guarantee of finding a block. These estimates are based on current network difficulty and your hashrate. Every hash has an equal chance.

Home Mining Assessment
Quad-chip open-source miner running four BM1366 chips at ~1.7 TH/s. Quiet enough for a home office and powered by 12V DC over XT30; a 12V/10A PSU is recommended. The USB port is for flashing only, not power.
The QAxe is a SHA-256 Bitcoin solo miner built on the original open-source Qaxe design from shufps and the wider OSMU (Open Source Miners United) community. It runs four BM1366 ASIC chips for an average hashrate of about 1.7 TH/s, packing meaningful solo-mining odds into a compact, desktop-friendly board.
The four BM1366 chips — the same generation of silicon found in the Antminer S19 XP — are arranged in a single UART daisy chain. The QAxe uses air cooling, runs quietly enough for a home office, and is powered by 12V DC through a standard XT30 connector (the same connector used by the Bitaxe Hex and many other open-source miners). The BM1366 silicon places the QAxe alongside the original NerdQAxe; the later NerdQAxe+ (BM1368) and NerdQAxe++ (BM1370) move to newer chip generations.
At roughly 1.7 TH/s the QAxe produces a modest amount of waste heat that is easy to live with in a home setting, while quadrupling the silicon of a single-chip Bitaxe for proportionally better odds in the solo lottery.
The QAxe is solo-mining capable, so you can point it at your own Bitcoin node or a solo pool such as solo.ckpool.org or public-pool.io for a shot at a full block reward.

Frequently Asked Questions
What are the current mining economics for the QAxe?
At $0.07/kWh, the QAxe currently shows an estimated daily net cost of $0.07 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 QAxe?
Yes, the QAxe scores 100/100 for home mining viability. It produces 40 dB of noise and draws 68W. It is suitable for home environments with appropriate placement considerations.
Can the QAxe heat my home?
The QAxe outputs approximately 232 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.
Does D-Central repair the QAxe?
Yes, D-Central provides professional repair services for the QAxe. Services include hashboard repair, control board diagnostics, fan replacement, and full refurbishment. Ship your miner to our Laval, Quebec facility for diagnosis and repair.
What power supply does the QAxe need?
The QAxe draws 68W of power. You need a power supply rated for at least 75W with appropriate voltage (12V DC (XT30 connector)). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect the miner and wiring.
