The Bitmain Antminer T17 was the budget-friendly entry point to the 7nm BM1397 chip generation, launched alongside the S17 and S17 Pro in 2019. Delivering 40 TH/s at 2,200W, the T17 offered miners a lower-cost way to access 7nm mining technology at the expense of reduced hashrate and efficiency. At 55 J/TH, the T17 was the least efficient member of the S17 family but still represented a significant upgrade over the S9 generation.
The “T” designation in Bitmain’s naming convention has traditionally indicated a value-tier product — using chips that did not meet the binning requirements for the “S” (standard) or “S Pro” models. The T17 used fewer BM1397 chips per hashboard (30 chips per board, 90 total) compared to the S17’s 144 chips, resulting in a lower hashrate but also lower manufacturing cost. This pricing strategy made the T17 accessible to home miners and small operations that could not justify the premium S17 Pro pricing.
In 2026, the T17 is well past its competitive prime for pure mining. However, its 2,200W power draw and ~7,500 BTU/h heat output position it as a viable space heater candidate. Like all S17-generation miners, the T17 has known reliability concerns that make access to professional repair services important. D-Central Technologies offers full repair and conversion services for the T17 platform.

Performance Analysis
At 55 J/TH, the T17 is the least efficient member of the S17 family: 22% less efficient than the standard S17 (45 J/TH) and 39% less efficient than the S17 Pro (39.5 J/TH). However, it still outperforms the entire S9 generation (93-96 J/TH) by a wide margin. Compared to the S19 (34.2 J/TH) and S21 (17.5 J/TH), the T17 falls well behind modern efficiency standards.
The T17’s value proposition was always about cost, not performance. In 2026, with used T17 units available for minimal cost, the equation is simple: if your electricity is cheap enough and you need the heat, the T17 can serve a purpose.
Daily and Monthly Power Costs
| Electricity Rate | Daily Power Cost | Monthly Power Cost | Viability |
|---|---|---|---|
| $0.05/kWh | $2.64 | $79 | Marginally viable — better as a space heater earning sats |
| $0.08/kWh | $4.22 | $127 | Unprofitable for pure mining — dual-purpose heating recommended |
| $0.10/kWh | $5.28 | $158 | Unprofitable — only viable as a space heater in cold climates |
| $0.12/kWh | $6.34 | $190 | Unprofitable — upgrade to a newer generation miner |
Heat Output
The T17 produces approximately 7,506 BTU/h of heat (2,200W × 3.412 BTU/W). This is a substantial amount of heat — more than many dedicated space heaters. For home miners using the T17 during heating season, this heat output directly offsets conventional heating costs. See our Best Miners for Space Heaters guide for comparisons.
Best Use Cases in 2026
Space Heater Conversion: The T17’s combination of significant heat output (~7,500 BTU/h) and very low acquisition cost makes it a solid choice for space heater conversion. While it earns less Bitcoin per watt than an S19 or S21, the hardware cost is negligible.
Budget Entry Point: For aspiring home miners who want experience with 7nm hardware without the investment of an S19 or S21, the T17 provides hands-on experience with the same chassis design, fan configuration, and firmware ecosystem used by newer Bitmain miners.
Undervolting Practice: The T17 is an excellent candidate for learning undervolting techniques with Braiins OS+ or Vnish. Reducing power to ~1,500-1,800W while maintaining 30-35 TH/s significantly improves efficiency and extends hardware life.
Common Issues & Repair
The T17 shares reliability challenges with the broader S17 generation:
- Hashboard solder cracking: Like all S17-generation miners, the T17 is prone to BM1397 chip solder joint failures from thermal cycling. Professional BGA rework is required.
- PSU failures: The integrated APW9/APW9+ power supply can fail, particularly in units that have experienced power surges or sustained high ambient temperatures. See our APW9 PSU Repair Guide.
- Temperature sensor errors: Faulty readings can trigger nuisance shutdowns. Sensor replacement or firmware-level workarounds may be needed.
- Fan failures: The 4-fan assembly runs at high RPM (6,000) and fans wear out, particularly bearings. Replace failed fans promptly to prevent thermal damage.

Frequently Asked Questions
Is the Antminer T17 still profitable in 2026?
At 55 J/TH, the T17 is not profitable for pure mining at standard electricity rates. Only miners with electricity below $0.05/kWh may see marginal returns. The primary value of the T17 in 2026 is as a space heater that earns Bitcoin, or as a low-cost learning platform.
How much electricity does the Antminer T17 use per day?
The T17 consumes approximately 2,200W continuously, translating to 52.8 kWh per day or about 1,584 kWh per month. At $0.10/kWh, that is $5.28/day or $158/month in electricity costs.
Can the Antminer T17 be used as a space heater?
Yes — the T17 outputs approximately 7,506 BTU/h of heat, which is significant heating capacity. D-Central offers space heater conversions for the T17 platform.
What is the difference between the T17 and S17?
The S17 delivers 56 TH/s at 2,520W (45 J/TH), while the T17 delivers 40 TH/s at 2,200W (55 J/TH). The S17 has 144 chips versus the T17’s 90 chips. The S17 is more efficient but typically costs more on the secondary market. Both share the same chassis, fans, and PSU.
Can the T17 run aftermarket firmware?
Yes, the T17 supports Braiins OS+, Vnish, and LuxOS aftermarket firmware. These allow undervolting, custom fan curves, and improved stability. See our Antminer Firmware Update Guide.
