MicroBT WhatsMiner M30S+
Affordable used-market option, good for large-scale deployments
Quick answer
The MicroBT WhatsMiner M30S+ is a Bitcoin miner rated about 100 TH/s at roughly 3,400 W (about 34 J/TH).
Professional-Grade Miner
This miner draws 3,400W, but this profile does not have a verified noise value. Do not substitute a generic dB estimate; verify the exact manufacturer manual and installation requirements before choosing a circuit or location.
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 3,400W, this miner outputs approximately 11,601 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 | $5.39 | $5.71 | $-0.32 |
| Weekly | $37.75 | $39.98 | $-2.23 |
| Monthly | $161.79 | $171.36 | $-9.57 |
| Yearly | $1,968.46 | $2,084.88 | $-116.42 |
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.

The documented M30S+ rating is 100 TH/s, 3400 W, and 34 J/TH. The manufacturer’s launch record and current official shop agree on that operating point.
The current shop SKU lists a 430 × 155 × 226 mm enclosure, P221B/P222B supply, AC 220–240 V input and −5°C to 35°C environment. Those chassis and supply details describe the current shop SKU; they must not be projected backward onto every historical M30S+ unit.
This profile therefore leaves control-board platform, ASIC part, noise, weight and launch price unfilled unless exact-unit evidence is available. Confirm a physical miner’s reported platform before firmware, recovery or parts selection.
