Description
The Antminer S17 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 proven Antminer S17 platform with BM1397 ASIC chips, this machine delivers serious SHA-256 hashpower while converting every watt of electricity into usable heat for your home. No energy is wasted — 100% of the power drawn becomes heat output, making it pound-for-pound as efficient as any electric heater on the market, except this one pays you back in Bitcoin.
D-Central’s custom quiet enclosure replaces the stock industrial fans with silent 120mm cooling, bringing noise levels down from a warehouse-grade roar to something you can live with in your home. Paired with our Space Heater platform and custom firmware tuning, the S17 Space Heater Edition runs undervolted for optimal efficiency — pushing 30-40 TH/s at 1,200-1,800W while outputting 4,100-6,100 BTU/hr of clean, dry heat. That is enough to keep a medium-to-large room warm through a Canadian winter while stacking sats around the clock.
Every unit is reconditioned in our Laval workshop: hashboards are inspected, underperforming chips removed, heatsinks upgraded where needed, and the entire machine stress-tested for 24 hours before it ships. This is not a stock miner in a box — it is a purpose-built heating appliance engineered by the team that has been building Bitcoin Space Heaters since 2018.

Dual-Purpose Value: Heat Your Home, Stack Sats
Traditional electric heaters convert electricity into heat at 100% efficiency. So does a Bitcoin miner. The difference is that the miner also generates Bitcoin while it heats. At 1,200W undervolted, the S17 Space Heater Edition delivers the same heat output as a standard portable heater — roughly 4,100 BTU/hr — while simultaneously mining Bitcoin 24/7. Your heating bill does not increase. You simply redirect electricity that was already being spent on heating into a machine that heats and earns. Over a 6-month Canadian heating season, the Bitcoin earned can substantially offset or even exceed your electricity costs. See our complete 5-year cost comparison for the full breakdown.
Quiet Enough for Your Living Room
Stock Antminer S17 units run at 75+ dB — roughly the volume of a vacuum cleaner. That is unacceptable indoors. D-Central’s Space Heater enclosure replaces all stock fans with Arctic P12 Silent 120mm fans, bringing noise down to approximately 50-55 dB — comparable to a quiet conversation or a standard refrigerator. The custom enclosure is engineered to direct airflow efficiently without trapping heat, so you get optimal cooling performance at a fraction of the noise. Combined with undervolting via BraiinsOS+, many users report the S17 Space Heater Edition blends right into the ambient noise of a busy household.
Undervolting: The Key to Home Mining
Running an ASIC miner at stock settings in your home is impractical — too loud, too hot, too power-hungry. That is why every S17 Space Heater Edition ships with BraiinsOS+ firmware pre-installed, enabling precise undervolting and autotuning. Dial the power down to 1,200W for a quiet, efficient heater that pushes ~30 TH/s. Need more heat on a cold night? Crank it up to 1,800W for ~40 TH/s and ~6,100 BTU/hr. You control the balance between hashrate, power consumption, and heat output based on what your home needs right now. This is what we mean by mining hacking — taking industrial hardware and tuning it for residential life.
Built for Canadian Winters
D-Central is headquartered in Laval, Quebec. We know cold. The S17 Space Heater Edition was designed for the reality of Canadian heating seasons that stretch from October to April. At undervolted settings, this unit comfortably heats a medium-to-large room while mining Bitcoin around the clock. Pair it with Home Assistant for smart thermostat control — set temperature thresholds, schedule mining intensity, and integrate it into your existing smart home setup. Some of our customers run multiple Space Heater Editions across different rooms, replacing traditional baseboard heaters entirely.
Plug-and-Play Setup
The S17 Space Heater Edition ships fully assembled and tested. Connect power, plug in an Ethernet cable, point it at your mining pool, and you are live. No soldering, no firmware flashing, no configuration headaches. BraiinsOS+ is pre-installed and pre-tuned. If you want to adjust settings, the web interface is straightforward. If you need help, D-Central’s support team has repaired and configured thousands of Antminers — we know this hardware inside and out.

Frequently Asked Questions
How much does it cost to run the S17 Space Heater Edition per month?
At 1,200W undervolted running 24/7, the S17 draws about 864 kWh per month. At a Canadian average electricity rate of $0.10/kWh, that is roughly $86/month. At 1,800W, expect around $130/month. Remember — this electricity is not wasted. It heats your home AND mines Bitcoin. During heating season, you would be spending this electricity on heating anyway. The Bitcoin earned offsets or can exceed the cost. Use our Mining Profitability Calculator to estimate returns at your local electricity rate.
How loud is it really? Can I sleep in the same room?
With the Arctic P12 silent fans and undervolted to 1,200W, the S17 Space Heater Edition runs at approximately 50 dB — similar to a quiet conversation or moderate rainfall. Most users find it comfortable in a living room, office, or workshop. For sleeping, it depends on your sensitivity to white noise. Some users sleep fine with it in an adjacent room or even the same room. It is significantly quieter than any stock ASIC miner, but it is not silent.
What room size can this heat?
At 1,200W (~4,100 BTU/hr), the S17 comfortably supplements heating in a 150-200 sq ft room. At 1,800W (~6,100 BTU/hr), it can serve as primary heat for a 300-400 sq ft room in moderate climates or strong supplemental heat in colder regions. At full stock power (2,520W / ~8,600 BTU/hr), it can handle 400-500+ sq ft — but stock power requires 240V and runs louder. Use our BTU Calculator to match your specific room.
Is Bitcoin mining with this unit actually profitable?
Profitability depends on your electricity rate, Bitcoin price, and network difficulty. The key insight is that during heating season, the electricity cost is effectively zero — you would be paying for heating regardless. The Bitcoin mined is pure bonus income. Outside heating season, you can power down or run at minimal settings. D-Central customers in Quebec (with electricity rates around $0.07/kWh) and other low-cost regions see the strongest economics. Check current numbers with our Mining Profitability Calculator.
Do I need 240V or can I use a regular 120V outlet?
It depends on your target power level. At 1,200W undervolted, the S17 can run on a standard 120V/15A circuit (drawing about 10A). At higher power levels (1,500W+), a 240V circuit is recommended for stable operation and to stay within safe amperage limits. At full stock power (2,520W), 240V is required. If you do not have a 240V outlet, an electrician can install one — it is a standard job similar to adding a dryer outlet. See our electrical requirements guide for full details.
How do I set it up?
The S17 Space Heater Edition ships fully assembled with BraiinsOS+ pre-installed. Setup is straightforward: (1) Place the unit where you want heat directed. (2) Connect the power cord to your outlet. (3) Plug in an Ethernet cable to your router. (4) Access the miner’s web interface from your browser to configure your mining pool. (5) Start mining. The whole process takes about 15 minutes. For step-by-step instructions with photos, see our Space Heater Assembly Guide.
What maintenance does it need?
Minimal. Blow out dust every 2-3 months with compressed air (more frequently if you have pets). Check fan operation periodically. The BraiinsOS+ firmware handles autotuning automatically. If a hashboard develops issues, D-Central offers professional ASIC repair services with fast turnaround. Keeping the unit in a clean, low-humidity environment will maximize its lifespan.
How long will this unit last?
The Antminer S17 uses BM1397 chips — a mature, well-understood ASIC design. With proper maintenance (regular dust cleaning, stable power, good ventilation), these units can run for years. D-Central reconditions every unit to 95%+ efficiency and stress-tests for 24 hours before shipping. The custom enclosure also helps extend component life by providing better airflow than stock configurations.
Can I use this in summer or only during heating season?
You can run it year-round, but in summer the heat output becomes a drawback rather than a benefit. Most Space Heater users run their units primarily during the heating season (October-April in Canada) and either power down in summer or reduce to minimal settings. Some creative users vent the hot air outdoors through a window duct or into a garage. The beauty of undervolting is flexibility — run it hard when you need heat, dial it back when you do not.
What is the warranty and return policy?
Every S17 Space Heater Edition includes a 90-day warranty. If any issues arise, D-Central provides prioritized repair service — we know these machines inside and out because we built them. Security seals must remain intact for warranty validation. All sales are final due to cryptocurrency market volatility. Full terms are available in our return and refund policy.
