Description
The Antminer T17 Space Heater Edition is a dual-purpose Bitcoin mining rig and home heater, designed and built by D-Central Technologies in Laval, Quebec. Based on Bitmain’s Antminer T17 platform with BM1397 ASIC chips, this machine mines SHA-256 (Bitcoin) while converting every watt of electricity into direct heat for your home. The T17 is the more accessible sibling of the S17 — delivering solid hashrate and reliable heat output at a lower price point, making it an excellent entry into serious dual-purpose mining.
D-Central’s custom quiet enclosure swaps out the stock industrial fans for silent 120mm cooling, dropping noise from an industrial 75+ dB to a home-friendly ~50-55 dB. Running on BraiinsOS+ firmware with undervolting enabled, the T17 Space Heater Edition operates at approximately 1,200W, producing ~26 TH/s of hashrate and ~4,100 BTU/hr of clean, dry heat — enough to comfortably warm a medium-sized room through the coldest months while stacking sats around the clock.
Every unit is reconditioned in our Laval workshop. Hashboards are inspected chip by chip, underperformers are removed until the unit hits 95%+ efficiency, heatsinks are upgraded where needed, and the complete machine is stress-tested for 24 hours before shipping. The T17 Space Heater Edition is not a stock miner stuffed into a case — it is a purpose-built residential heating appliance from the team that pioneered Bitcoin Space Heaters in 2018.

Dual-Purpose Value: Mine Bitcoin While You Heat
Every electric heater converts electricity to heat at 100% efficiency. A Bitcoin miner does the same — except it also produces Bitcoin. The T17 Space Heater Edition running at 1,200W undervolted delivers the same ~4,100 BTU/hr as a standard portable electric heater, but it earns Bitcoin while doing it. During Canada’s 6-month heating season, the electricity you spend on heating is doing double duty. The Bitcoin earned can substantially offset your electricity bill — and in many cases, turn heating from a pure cost into a net-positive operation. See our complete 5-year cost comparison for the detailed math.
Quiet Operation for Real-Life Homes
A stock Antminer T17 runs at 75+ dB — unusable indoors. D-Central’s Space Heater enclosure replaces all stock fans with silent 120mm fans (Arctic P12 or Noctua options), bringing operating noise to approximately 50-55 dB. That is comparable to a quiet conversation or moderate background noise. Combined with undervolting via BraiinsOS+ (which reduces both power draw and heat), the T17 Space Heater Edition operates at a level that most households find unobtrusive in a living room, office, or workshop. The custom enclosure is engineered to optimize airflow without trapping heat — you get effective cooling at a fraction of the noise.
The Budget-Friendly Path to Dual-Purpose Mining
The T17 shares the same BM1397 chip architecture as the S17, but at a more accessible price point. At 1,200W undervolted, the T17 delivers ~26 TH/s — less than the S17’s ~30-40 TH/s at the same wattage — but the heat output is identical at ~4,100 BTU/hr. If your primary goal is heating with Bitcoin as a bonus, the T17 offers the same thermal performance at a lower upfront cost. For miners who want to maximize hashrate per watt, the S17 Space Heater Edition or the S19 Space Heater Edition deliver better efficiency — but the T17 gets you into the game at a lower entry price.
Built for Canadian Winters
D-Central is headquartered in Laval, Quebec. We designed the T17 Space Heater Edition for the same winters we live through — heating seasons that run from October to April with temperatures regularly hitting -20C and below. At 1,200W, this unit comfortably heats a medium-sized room (150-250 sq ft) as supplemental or primary heat. Pair it with Home Assistant for smart thermostat control — set temperature targets, schedule mining intensity by time of day, and integrate it into your existing home automation. Some of our customers run multiple Space Heater Editions across different rooms, replacing traditional electric heaters entirely while earning Bitcoin in every room of the house.
Plug-and-Play Setup
The T17 Space Heater Edition ships fully assembled and tested. No soldering, no firmware flashing, no complex configuration. Setup takes about 15 minutes: connect power, plug in Ethernet, access the web interface from your browser, enter your mining pool details, and start mining. BraiinsOS+ is pre-installed and pre-tuned for undervolted operation. If you want to adjust power levels or switch pools, the web interface makes it straightforward. For step-by-step instructions, see our Space Heater Assembly Guide.

Frequently Asked Questions
How much does it cost to run the T17 Space Heater Edition per month?
At 1,200W undervolted running 24/7, the T17 draws about 864 kWh per month. At a Canadian average of $0.10/kWh, that is roughly $86/month in electricity. But here is the key: during heating season, you would be spending that electricity on heating anyway. The T17 gives you the same heat as a 1,200W electric heater plus Bitcoin earnings on top. Use our Mining Profitability Calculator to estimate your returns at your local electricity rate.
How loud is it? Can I have it in my living room?
With silent fans and undervolted to 1,200W, the T17 Space Heater Edition runs at approximately 50-55 dB — similar to a quiet conversation or the hum of a refrigerator. Most users find this perfectly acceptable for a living room, office, or workshop. It is dramatically quieter than a stock Antminer T17 (75+ dB), which sounds like a vacuum cleaner. The standard edition with capped RPM stock fans runs at about 70 dB; the Noctua or Arctic P12 editions are noticeably quieter.
What room size can the T17 Space Heater heat?
At 1,200W undervolted (~4,100 BTU/hr), the T17 is best suited for medium rooms of 150-250 sq ft — a bedroom, home office, or den. In well-insulated spaces or moderate climates, it can serve as primary heat. In older buildings or extreme cold, use it as supplemental heating alongside your existing system. At stock power (2,200W / ~7,500 BTU/hr with 240V), it can handle rooms up to 300-400 sq ft. Use our BTU Calculator to find the right setting for your space.
How does the T17 compare to the S17 Space Heater Edition?
Both use the same BM1397 chip and share the same D-Central enclosure design. The key differences: the S17 delivers higher hashrate (~30-40 TH/s undervolted vs the T17’s ~26 TH/s), meaning it earns more Bitcoin at similar power levels. The S17 also has more headroom — you can push it to 1,800W for more heat and hashrate, while the T17 is optimized for ~1,200W operation. If you want maximum hashrate flexibility and heating range, the S17 Space Heater Edition is the better choice. If you want a solid, reliable heater at a lower upfront cost, the T17 delivers.
Is mining with the T17 profitable?
During heating season, profitability is almost always positive because the electricity cost is effectively shared with your heating bill — you would be paying to heat anyway. The Bitcoin mined is bonus income on top of heat you already need. Outside heating season, profitability depends on your electricity rate and current Bitcoin price/difficulty. The T17 is not the most efficient miner on the market by J/TH, but when the heat has value, the economics change entirely. Check current numbers with our Mining Profitability Calculator.
Do I need a special electrical outlet?
At 1,200W undervolted, the T17 can run on a standard 120V/15A household circuit (drawing about 10A). At higher power levels or stock settings (2,200W), a 240V circuit is recommended. If you need a 240V outlet installed, any licensed electrician can do it — it is similar to adding a dryer or oven outlet. Never run more than one mining unit per circuit breaker. See our electrical requirements guide for details.
How do I set it up?
The T17 Space Heater Edition arrives fully assembled and pre-configured with BraiinsOS+ firmware. Place the unit, connect power, plug in an Ethernet cable to your router, and access the web interface from any browser on your network. Enter your mining pool credentials and you are mining. Total setup time is about 15 minutes. For a detailed walkthrough, see our Space Heater Assembly Guide.
What maintenance is required?
Bitcoin Space Heaters are low-maintenance. Blow out accumulated dust with compressed air every 2-3 months (more often if you have pets or a dusty environment). Check that fans are spinning freely. BraiinsOS+ handles autotuning automatically. Keep the unit in a low-humidity environment and ensure adequate airflow around the enclosure. If you ever need repairs, D-Central’s ASIC repair team services all Antminer models.
How long will the T17 last?
The BM1397 chips in the T17 are a mature, well-proven design. With proper care — clean power, regular dust removal, low humidity, good ventilation — these units last for years. D-Central reconditions every unit to 95%+ efficiency and runs a full 24-hour stress test before shipping. Undervolted operation also extends component life by reducing thermal and electrical stress compared to running at stock settings.
What is the warranty?
Every T17 Space Heater Edition includes a 90-day warranty. If issues arise, D-Central provides prioritized repair service from our Laval workshop — the same technicians who built your unit will service it. Security seals must remain intact for warranty coverage. All sales are final due to cryptocurrency market volatility. See our return and refund policy for full terms.
