Description
The BitChimney is D-Central’s original chimney-style Bitcoin space heater — a single-hashboard Antminer S19-series miner wrapped inside a vertical 3D-printed chimney enclosure that exploits natural convection to silently heat any room. One hashboard. One standard 120V outlet. Zero wasted energy. Every watt that enters the BitChimney leaves as heat and as SHA-256 hashes securing the Bitcoin network.
This is not a bare miner propped in a corner. D-Central engineered the BitChimney from the ground up: a Loki Kit enables the single hashboard to run on household 120V power, silent 120mm fans replace the industrial blowers, and the chimney form factor lets hot air rise naturally while drawing cool air from below. The result is a conversation piece, a functional space heater, and an active Bitcoin miner — all in one compact, Canadian-made package.
Available in two variants: the BitChimney S19 (~21 TH/s, ~600W) for budget-conscious miners, and the BitChimney S19j Pro (~24 TH/s, ~650W) for those who want more hashrate per watt. Both versions come in your choice of Orange or Black enclosure, with Gelid Gale-01 or Arctic P12 Max fans.

The Chimney Effect: Engineered Airflow, Not Afterthought Airflow
Most Bitcoin space heaters are horizontal boxes that push hot air out the back. The BitChimney is different by design. The vertical chimney form factor exploits a basic principle of physics: hot air rises. Cool room air enters through the lower intake, passes across the hashboard and PSU, absorbs the heat, and exits through the top of the chimney. This natural convection, assisted by four silent 120mm fans, creates a self-reinforcing thermal loop that distributes warmth upward and outward into the room without the turbulence or noise of high-speed industrial blowers.
The chimney enclosure also acts as a sound barrier. The 3D-printed housing dampens mechanical vibration from the fans and isolates the hashboard hum. At 40-45 dB, the BitChimney is quieter than a typical refrigerator. You can run it in a living room, home office, or bedroom without it demanding attention — unless you want to show it off.
Single Hashboard, Maximum Efficiency
The BitChimney runs a single Antminer hashboard with a Loki Kit — D-Central’s proven circuit that enables standard Antminer hashboards to run on 120V household power through an APW3 PSU. One hashboard means the power draw stays under 650W, well within the capacity of a standard 15A household circuit. No electrician. No 240V installation. No dedicated breaker panel. Plug it in and start hashing.
Running on custom firmware (VNish or BraiinsOS+), the hashboard is tuned to a fixed frequency that balances hashrate against thermal output and power consumption. The S19 variant delivers approximately 21 TH/s at 600W; the S19j Pro variant pushes approximately 24 TH/s at 650W with better efficiency (fewer joules per terahash). Both variants mine SHA-256 — you are mining Bitcoin directly, not an altcoin with a Bitcoin payout. Your hashes go straight to your chosen pool, and your sats come straight back.
A Conversation Piece That Earns Sats
The BitChimney does not look like a bare miner. The tall, narrow chimney profile sits naturally beside furniture, in a corner, or next to a bookshelf. Available in Bitcoin Orange or Black, the enclosure is designed to be visible and intentional — a statement piece that says “this home mines Bitcoin.” Guests will ask about it. You will explain the first law of thermodynamics and then show them your mining dashboard. That is the BitChimney experience.
The 3D-printed enclosure is manufactured at D-Central’s facility in Laval, Quebec using industrial-grade filament rated for continuous thermal exposure. Every unit is assembled, wired, tested under load for 24 hours, and inspected before shipping. This is Canadian craftsmanship applied to cypherpunk technology.
Plug-and-Play Setup
The BitChimney ships fully assembled and ready to mine. Setup takes under 10 minutes:
- Place the BitChimney on a flat surface with at least 6 inches of clearance above the chimney opening and clear airflow below
- Plug the power cord into a standard 120V household outlet (dedicated 15A circuit recommended)
- Connect an Ethernet cable from your router to the miner’s RJ45 port
- Access the miner’s web interface from any device on the same network
- Enter your mining pool address and worker credentials
- Save and start hashing
No WiFi built in — the Antminer platform requires wired Ethernet. If running a cable is impractical, D-Central sells Vonets WiFi bridge adapters that plug directly into the miner’s Ethernet port. For detailed step-by-step instructions with photos, see the full BitChimney Installation and Setup Guide.

Frequently Asked Questions
What algorithm does the BitChimney mine?
The BitChimney mines SHA-256, the same algorithm as Bitcoin. Your hashes go directly to your mining pool and you earn Bitcoin (BTC) or satoshis as your payout. This is real Bitcoin mining, not mining an altcoin and auto-converting. Both the S19 and S19j Pro variants use SHA-256 ASIC chips.
Can I plug the BitChimney into a regular household outlet?
Yes. The BitChimney is specifically designed to run on a standard 120V / 15A North American outlet (NEMA 5-15). No electrician, no special wiring, no 240V circuit required. We recommend a dedicated circuit (not shared with other high-draw appliances like microwaves or space heaters) for stable operation. See our Electrical Requirements Guide for full details.
How loud is the BitChimney?
At 40-45 dB with the silent fans, the BitChimney is comparable to a quiet refrigerator or a library environment. The chimney enclosure acts as a sound barrier, dampening fan vibration and hashboard hum. It is designed for living rooms, offices, and bedrooms — spaces where noise matters. It is significantly quieter than a stock Antminer (~75 dB) and quieter than most other space heater editions.
What is the difference between the S19 and S19j Pro variants?
The S19j Pro variant uses a more efficient hashboard that delivers approximately 24 TH/s at 650W compared to the S19’s 21 TH/s at 600W. The S19j Pro produces more hashes per watt (better J/TH efficiency), meaning you earn slightly more Bitcoin for the same electricity cost. Both variants fit the same enclosure and produce similar heat output. If budget allows, the S19j Pro is the better long-term value.
Should I choose Gelid Gale-01 or Arctic P12 Max fans?
Both are premium 120mm silent fans. The Gelid Gale-01 is D-Central’s technician pick — slightly higher static pressure, excellent bearing longevity, and marginally quieter under sustained load. The Arctic P12 Max offers comparable performance at a lower cost. Either choice delivers whisper-quiet operation. If you are unsure, go with the Gelid.
Does the BitChimney have WiFi?
No. The Antminer platform requires a wired Ethernet connection. You will need to run an Ethernet cable from your router to the BitChimney. If that is not practical for your space, D-Central sells Vonets WiFi bridge adapters that plug into the miner’s Ethernet port and connect wirelessly to your home network. They work reliably and are a clean solution for rooms without Ethernet jacks.
How much Bitcoin will the BitChimney earn?
Mining revenue depends on the current Bitcoin price, network difficulty, pool fees, and your electricity cost. At 21-24 TH/s, the BitChimney is a low-hashrate miner — you will not get rich from it. The real value proposition is that you are heating your home anyway. A 600-650W ceramic space heater costs the same to run and earns zero. The BitChimney earns you sats while providing identical heat. Use the D-Central Mining Profitability Calculator to estimate current earnings for your electricity rate.
Is the BitChimney safe to run unattended?
Yes. The BitChimney runs at lower power than a standard kitchen toaster. The 3D-printed enclosure uses industrial filament rated for sustained thermal exposure. The Loki Kit and APW3 PSU include overcurrent protection. The firmware monitors chip temperatures and will throttle or shut down if temperatures exceed safe thresholds. As with any heating device, ensure adequate clearance above the chimney opening (6+ inches minimum) and do not block the lower air intake.
Can I use the BitChimney as my only heat source?
For a small, well-insulated room (100-150 sq ft), the BitChimney can serve as a primary heat source during moderate cold. For Canadian winters in larger spaces, it is best used as supplemental heat — reducing the load on your main heating system while earning Bitcoin. Many customers run a BitChimney in their home office all winter and report a noticeable reduction in their central heating usage. For larger coverage, consider The Urlacher at 1,200W / 4,094 BTU.
What if my BitChimney needs repair?
The BitChimney includes a 90-day warranty. If issues arise, D-Central provides prioritized ASIC repair services from our facility in Laval, Quebec. We built this machine — we know every component intimately. Keep the security seals intact for warranty coverage. After the warranty period, D-Central still offers repair services at standard rates. We do not abandon our products.
Why D-Central
D-Central Technologies assembles and ships every BitChimney from Laval, Quebec, Canada. The Loki Kit that enables 120V single-hashboard operation was pioneered by D-Central. Every unit is assembled, wired, load-tested for 24 hours, and quality-checked by our technicians before it ships.
We have been building Bitcoin mining hardware since 2016. We pioneered the Bitcoin space heater concept for home miners. We created the original Bitaxe Mesh Stand. We repair more ASICs per year than most companies sell. When you buy a BitChimney, you are buying from the people who assembled it, tested it, and will fix it if anything goes wrong.
Every hash counts. The BitChimney is D-Central’s proof that Bitcoin mining belongs in every home — not locked behind industrial power infrastructure and data center walls. Plug it in, point it at a pool, and start heating your room with sats.
Reconditioned Excellence
Every Antminer hashboard inside the BitChimney undergoes D-Central’s full reconditioning process. We do not simply wipe down a used board and ship it. Each board is inspected, tested, and benchmarked. After assembly into the BitChimney enclosure, the complete unit runs under load for 24 hours before packing. What you receive has already proven it can hash.
Shipping, Customs, and Final Sale
- Processing time: Standard is under 24 hours; allow up to 5 business days for testing, packing, and shipping.
- Shipping and customs: Listed price does not include shipping charges, customs fees, or taxes. International buyers should verify local import regulations to avoid unexpected costs.
