Best Bitcoin Mining Heaters 2026: Complete Comparison Guide

The best Bitcoin mining heaters in 2026 are the D-Central S9 Space Heater Edition for best overall value, the Heatbit Trio for beginners, and the D-Central S19 Space Heater Edition for maximum heat output. Bitcoin mining heaters convert 100% of electricity into usable heat while simultaneously mining BTC — making your heating bill work double duty. In this guide, we compare 12+ models with real specs, pricing, and honest reviews.

What Is a Bitcoin Mining Heater?

A Bitcoin mining heater is any device that uses ASIC (Application-Specific Integrated Circuit) chips to mine Bitcoin while converting 100% of the electricity it consumes into usable heat. This is not a gimmick — it is thermodynamics.

Every electrical device converts its input energy into heat. Your toaster, your laptop, your traditional space heater — they all produce heat as output. The difference is that a traditional 1,500W electric space heater converts electricity into heat and nothing else. A 1,500W Bitcoin mining heater converts that same electricity into the exact same amount of heat plus Bitcoin.

The physics are straightforward: 1 watt = 3.412 BTU/hr. A 1,500W electric heater produces ~5,118 BTU/hr. A 1,500W Bitcoin miner produces ~5,118 BTU/hr plus Bitcoin. Same heat. Same electricity cost. But one of them pays you back.

Think of it as a rebate on your heating bill. You are going to spend money on electricity for heat regardless. A Bitcoin mining heater lets you recoup a portion — sometimes a significant portion — of that cost in BTC. In cold climates like Canada, where heating season runs 6–8 months, the economics become compelling.

Our Top Picks for 2026

Best Overall: D-Central S9 Space Heater Edition

The S9 Space Heater Edition delivers an unbeatable combination of price, heat output, and simplicity. Starting at just $235 CAD (~$170 USD), it provides up to 4,606 BTU/hr at stock settings — enough to heat a 150–250 sq ft room as a primary heat source. Undervolted to ~800W, it runs on a standard 120V outlet while still producing meaningful hashrate and heat. The 90-day warranty, silent Arctic P14 Max fans, and plug-and-play setup make this the easiest recommendation for anyone exploring Bitcoin heating for the first time at a price point that makes the economics work even in a bear market.

Best for Beginners: Heatbit Trio

If you want the absolute simplest unboxing experience and a device that looks like it belongs in a modern living room, the Heatbit Trio is the answer. It requires zero mining knowledge — plug it in, connect to WiFi, and it handles pool selection, firmware, and payouts automatically. It also doubles as an air purifier with HEPA filtration. The trade-off is significant: at 10 TH/s and 400W, you are paying $849 USD for far less hashrate and heat output than you would get from D-Central alternatives at lower price points. But for someone who values aesthetics and simplicity above all else, the Trio earns its place.

Best Budget: D-Central L3+ Space Heater Edition

At $295 CAD (~$210 USD), the L3+ Space Heater Edition is the quietest pre-built mining heater on this list at 30–38 dB — genuinely whisper-quiet. It mines Scrypt (Litecoin/Dogecoin) instead of SHA-256, providing algorithm diversification. The 800W draw and 2,730 BTU output are ideal for bedrooms and small offices. This is the unit you put in a room where silence matters.

Best Performance: D-Central S19 Space Heater Edition

When you need serious heat and serious hashrate, the S19 Space Heater Edition is unmatched. At full 240V power, it delivers up to 95 TH/s and 11,089 BTU/hr — enough to heat a 400–600 sq ft space as a primary heat source. Even undervolted on 120V, it pushes 50–70 TH/s while producing 5,100–8,190 BTU/hr. Pre-installed BraiinsOS+ firmware gives you granular per-chain power control. This is the choice for dedicated miners in cold climates who want to maximize both their hashrate and their heating capacity.

Most Innovative: Superheat H1

The Superheat H1 is not a space heater — it is a 50-gallon water heater that replaces the resistive heating elements in a standard tank with Bitcoin mining ASICs. Water heating accounts for roughly 20% of residential energy use, and the H1 is the first product to attack this massive slice of the energy pie with proof-of-work. At ~$2,000 USD with claims of $1,000/year in BTC earnings, the payback period could be as short as two years. Full specs are still emerging post-CES 2026, but the concept alone earns this product the innovation award.

Individual Product Reviews

D-Central S9 Space Heater Edition — Best Overall Value

View Product →

The Antminer S9 is the Toyota Corolla of Bitcoin mining — proven, reliable, and everywhere. D-Central takes reconditioned S9 units, replaces the ear-splitting stock fans with silent 140mm Arctic P14 Max or Noctua fans, installs them in a custom 3D-printed enclosure, and pre-configures the firmware for residential use. The result is a plug-and-play heater that runs at 35–40 dB (quieter than a refrigerator) while producing real hashrate.

Pros:

• Unbeatable price point — $235 CAD is the lowest entry price for any pre-built Bitcoin heater on the market
• Proven BM1387 chips with years of field reliability data
• Runs on 120V when undervolted — no electrician needed
• Extensive community support and documentation for the S9 platform

Cons:

• Oldest-generation chips (16nm) means lower efficiency — 98 J/TH vs. modern 20–30 J/TH
• Hashrate-to-dollar earning ratio is the lowest on this list
• Reconditioned hardware — these are used machines given a second life, not brand new

Best For: Budget-conscious buyers, first-time Bitcoin heater owners, anyone who wants to test the concept without significant financial commitment.

D-Central L3+ Space Heater Edition — Quietest Mining Heater

View Product →

The L3+ Space Heater Edition is the stealth option. At 30–38 dB, it is genuinely whisper-quiet — you can run this in a bedroom while sleeping without issue. It mines Scrypt instead of SHA-256, meaning you are mining Litecoin and Dogecoin rather than Bitcoin directly. Some miners prefer this for diversification; others prefer pure BTC exposure.

Pros:

• Quietest pre-built mining heater available at 30–38 dB
• Algorithm diversification (Scrypt vs. SHA-256)
• Affordable at $295 CAD
• Moderate power draw suits smaller spaces

Cons:

• Requires 240V — may need a dedicated outlet in some homes
• Does not mine Bitcoin directly (mines LTC/DOGE, which can be auto-converted)
• Lower heat output — supplemental heating only for larger rooms

Best For: Bedroom use, noise-sensitive environments, miners who want Scrypt algorithm exposure.

D-Central S17 Space Heater Edition — Mid-Range Workhorse

View Product →

The S17 edition sits in the sweet spot between the budget S9 and the flagship S19. With BM1397 chips (a significant generational upgrade over the S9’s BM1387), it delivers far better efficiency while still being available at a reasonable price. At stock 240V settings, it outputs a massive 8,598 BTU/hr — enough to serve as the primary heat source for a living room. Undervolted on 120V, it is still a potent 4,094 BTU/hr heater.

Pros:

• Excellent balance of hashrate, heat output, and price
• BM1397 chips offer significantly better efficiency than the S9
• BraiinsOS+ pre-installed for autotuning and undervolting
• Flexible power profiles from 1,200W to 2,520W

Cons:

• Louder than the S9 and L3+ editions at 50–55 dB
• Full power requires 240V circuit
• Currently out of stock (back-in-stock notifications available)

Best For: Dedicated home miners who want a meaningful hashrate jump over the S9 without the S19’s price premium. Ideal for garages, workshops, and larger living spaces.

D-Central S19 Space Heater Edition — Maximum Performance

View Product →

This is the flagship. The S19 Space Heater Edition packs an Antminer S19 (or S19j Pro, S19k Pro variants) into D-Central’s custom silent enclosure with Arctic P12 Max or Noctua iPPC 3000 fans. At 240V full tilt, it pushes 95 TH/s with 11,089 BTU/hr — that is a legitimate furnace-replacement level of heat output. Even dialed down to 120V, it delivers 50–70 TH/s and 5,100–8,190 BTU/hr.

The BraiinsOS+ firmware provides per-chain power control, meaning you can tune each hashboard individually for the perfect balance of hashrate, power consumption, and heat output. Home Assistant integration lets you control it like a smart thermostat — set target temperatures and let the miner ramp up or down automatically.

Pros:

• Highest hashrate and BTU output of any pre-built Bitcoin heater in this price range
• BM1398 chips with excellent efficiency (~34 J/TH stock, improvable with BraiinsOS+)
• Home Assistant integration for smart thermostat control
• Multiple S19 variants available (S19, S19j Pro, S19k Pro)

Cons:

• Full power mode requires a 240V outlet and dedicated circuit
• At 3,250W stock, it draws significant electricity
• Largest physical footprint of the D-Central lineup at 13.2 kg

Best For: Serious home miners in cold climates. Basements, garages, workshops, and dedicated mining rooms. Anyone who wants their heater to pull meaningful hashrate weight on the network.

D-Central Slim Edition — Apartment-Friendly

View Product →

The Slim Edition is D-Central’s answer to a common problem: most ASICs are too large, loud, and power-hungry for apartments and condos. By using a single hashboard from S19 or S21 series machines in a compact custom chassis, the Slim Edition delivers modern-generation hashrate (up to 44 TH/s with the S21 variant) while staying under 930W — well within any standard 120V outlet’s capacity.

Available in four variants: S19 (26 TH/s), S19j Pro (30 TH/s), S19k Pro (38 TH/s), and S21 (44 TH/s). The S21 variant at 20.9 J/TH is the most efficient option in D-Central’s entire space heater lineup.

Pros:

• Compact form factor designed specifically for apartments
• S21 variant offers best-in-class efficiency at 20.9 J/TH
• Runs on any standard 120V outlet
• VNish firmware pre-configured with Loki control board

Cons:

• Noisier than the S9 or L3+ editions at 55–60 dB
• Single hashboard means lower total heat output
• Uses reconditioned/recycled hashboards

Best For: Apartment dwellers, condo owners, anyone limited to standard 120V outlets who still wants modern-gen hashrate.

D-Central Loki Edition — Dual-Hashboard Power

View Product →

The Loki Edition is the step up from the Slim — it packs two hashboards instead of one, delivering up to 56 TH/s (S19k Pro variant) at 1,100–1,200W. This puts it in a compelling middle ground: more power than the Slim Edition, but still manageable on residential circuits. It runs on both 110V and 240V, with BraiinsOS+ or VNish firmware depending on configuration.

A notable touch: $5 from every Loki Edition sale supports Open Source Miners United (OSMU), the nonprofit promoting open-source mining hardware.

Pros:

• Dual hashboards for double the power of the Slim Edition
• S19k Pro variant pushes 56 TH/s — serious hashrate in a residential package
• Supports both 110V and 240V
• Supports OSMU with every purchase

Cons:

• This is a modded residential machine, not a stock factory unit — set expectations accordingly
• At 1,100–1,200W on 110V, you are near the limit of a standard 15A circuit
• Reduced airflow from silent fans means it should not be enclosed in tight spaces

Best For: Miners who want more hashrate than the Slim Edition without the full S19’s power demands. Good for larger bedrooms, offices, and supplemental basement heating.

BitChimney — Vertical Convection Design

View Product →

The BitChimney takes a different approach to form factor. Its vertical chimney-style enclosure uses natural convection principles — hot air rises through the unit, creating a natural draft that assists the fans. D-Central carries the BitChimney with S19 and S19j Pro hashboards, delivering 21–24 TH/s at a modest 600–650W. It plugs into any standard 120V household outlet.

The vertical design also has a practical advantage: it takes up less floor space than horizontal units. At 45 x 30 x 15 cm, it can sit in a corner or beside furniture without dominating a room.

Pros:

• Unique vertical design maximizes natural convection and minimizes floor space
• Low 600–650W draw runs easily on any 120V outlet
• Quiet at 40–45 dB — comparable to a refrigerator
• Modern S19-generation hashboards for good efficiency

Cons:

• Higher price per TH/s compared to the S9 or Slim Edition
• No WiFi — Ethernet only
• Lower total heat output than multi-hashboard configurations

Best For: Small apartments, offices, and spaces where vertical form factor and quiet operation are priorities.

Heatbit Trio — Consumer-Friendly Entry Point

Heatbit has done something no other company in this space has managed: they made a Bitcoin miner that your spouse would not object to having in the living room. The Trio is a sleek, tower-style device that looks like a premium air purifier, not a mining rig. The companion app handles everything — pool selection, firmware updates, earnings tracking — with zero mining knowledge required.

But here is the reality check: at 10 TH/s and 400W, the Trio produces only 1,365 BTU/hr of heat. For context, that is less heat than a small space heater and about half what the $235 CAD D-Central S9 produces. You are paying a significant premium for the design and simplicity.

The built-in HEPA air filtration is a genuinely unique feature that no competitor offers. If you value air quality alongside heating and mining, this matters.

Pros:

• Best-in-class industrial design and aesthetics
• Zero-knowledge setup via companion app
• Built-in HEPA air purification
• UL safety certified

Cons:

• Extremely low hashrate for the price — 10 TH/s for $849 USD
• Only 1,365 BTU/hr — insufficient as a primary heat source for most rooms
• Closed ecosystem — limited firmware customization
• Repair and servicing tied to Heatbit; no third-party repair option

Best For: Non-technical users who want a plug-and-play experience with premium aesthetics. People who value the air purification feature. Those who prioritize simplicity over hash-per-dollar value.

Heatbit Maxi & Maxi Pro — Consumer Power Play

The Maxi and Maxi Pro are Heatbit’s answer to the “not enough hashrate” criticism of the Trio. The Maxi pushes 39 TH/s at 1,200W, while the Maxi Pro hits 60 TH/s at 1,500W — placing the Pro in the same hashrate and power class as D-Central’s S19 Space Heater Edition at undervolted settings.

Both models retain the HEPA air purification, premium design, and app-controlled simplicity of the Trio. The Maxi Pro at 60 TH/s and 1,500W puts out 5,118 BTU/hr — a meaningful amount of heat for a 200–300 sq ft room.

The pricing comparison is telling, however. The Maxi Pro at $1,499 USD (~$2,100 CAD) delivers 60 TH/s. The D-Central S19 Space Heater Edition starts at $755 CAD (~$540 USD) and delivers 50–95 TH/s. The Heatbit commands a premium for its consumer-friendly design, air purification, and brand positioning. Whether that premium is worth it depends on your priorities.

Important note: The Maxi Pro ships in August 2026. The standard Maxi is available sooner. Check Heatbit’s website for current delivery timelines.

Pros:

• Competitive hashrate (especially Maxi Pro at 60 TH/s)
• Premium consumer design with HEPA filtration
• App-controlled simplicity
• UL safety certified with tip-over protection

Cons:

• Significant price premium over comparable hashrate alternatives
• Closed ecosystem with no third-party firmware support
• Maxi Pro not shipping until August 2026
• Repair servicing limited to Heatbit

Best For: Buyers who want a premium all-in-one package with air purification and are willing to pay a premium for design and simplicity.

Canaan Avalon Mini 3 — OEM Manufacturer Direct

The Avalon Mini 3 is significant because it comes from Canaan — one of the original ASIC chip manufacturers. This is not a repurposed mining rig; it is a purpose-built home mining heater designed from the ground up with 66 advanced 4nm ASIC chips. The 21.3 J/TH efficiency is excellent, and the multiple operating modes (Mining, Heater Eco, Heater Super, Night) give users real flexibility.

At 800W and 2,730 BTU/hr, however, the heating capacity is modest. Canaan claims ~80 sq ft of coverage at full power, which is honest but limited. The Avalon Mini 3 shines as an efficient miner with heating as a secondary benefit, rather than a primary heat source.

Pros:

• Purpose-built by an actual ASIC chip manufacturer — not a retrofit
• Latest 4nm chips with excellent 21.3 J/TH efficiency
• Multiple operating modes including ultra-quiet Night Mode (33 dB)
• Built-in WiFi for wireless operation

Cons:

• $1,119 USD is expensive for 37.5 TH/s compared to D-Central alternatives
• Only ~80 sq ft of effective heating at full power
• Limited repair infrastructure outside of Canaan’s warranty

Best For: Buyers who want a brand-new, purpose-built device from a major manufacturer with the latest chip technology. Those who prioritize mining efficiency over raw heat output.

Superheat H1 — The Water Heater Revolution

The Superheat H1 represents a genuinely new category. Instead of heating air, it heats water — replacing the resistive heating elements in a standard 50-gallon electric water heater tank with Bitcoin mining ASICs. The waste heat from mining is transferred directly into the water, producing domestic hot water while earning BTC.

Why does this matter? Water heating accounts for approximately 18–20% of residential energy consumption in the United States — second only to space heating. The H1 targets a massive energy expenditure that no other Bitcoin mining product has addressed.

Superheat claims the H1 can generate approximately $1,000/year in Bitcoin earnings, potentially offsetting up to 80% of electricity and water heating costs. At a ~$2,000 purchase price, the claimed payback period is roughly two years. These are company projections that depend heavily on Bitcoin price, network difficulty, and electricity costs — but the underlying thermodynamic principle is sound.

Unveiled at CES 2026, the H1 is still in early production. Full technical specifications (hashrate, exact wattage, noise levels) have not been publicly disclosed. Future versions are planned to support distributed AI training workloads in addition to Bitcoin mining.

Pros:

• Targets a massive untapped energy category — domestic water heating
• Year-round utility (you always need hot water, unlike seasonal space heating)
• Projected 2-year payback period
• Could become invisible infrastructure — mine Bitcoin without anyone knowing

Cons:

• Not yet widely available — early production phase
• Full specs not disclosed
• $2,000 USD is a significant investment for an unproven product category
• Professional installation likely required (plumbing + electrical)
• Company earnings projections should be treated with healthy skepticism

Best For: Early adopters who want to be on the cutting edge of Bitcoin mining infrastructure. Homeowners replacing an aging electric water heater. Anyone who wants year-round mining utility beyond seasonal heating.

D-Central Space Heater Lineup: What Makes Them Different

D-Central Technologies has been building Bitcoin space heaters since the concept was still niche. Based in Laval, Quebec, Canada, D-Central does not simply slap a fan on a miner and call it a heater. Every unit goes through a methodical conversion process:

1. Sourcing & Reconditioning: D-Central sources decommissioned ASIC miners from large mining operations. Each unit is fully reconditioned — cleaned, tested, and repaired as needed by experienced ASIC technicians.
2. Silent Fan Conversion: The stock industrial fans (which can hit 75–85 dB on machines like the S9) are replaced with silent 140mm or 120mm fans from Arctic, Noctua, or Gelid. This drops noise levels to 30–55 dB depending on the model.
3. Custom Enclosure: Each unit is housed in a custom 3D-printed PETG enclosure designed for residential use. The enclosures optimize airflow while keeping the unit compact and aesthetically acceptable for a home environment.
4. Firmware Optimization: Units ship with BraiinsOS+, VNish, or other custom firmware pre-configured for residential power profiles. Undervolting settings are dialed in for 120V operation where applicable.
5. 24-Hour Soak Test: Every unit runs for a full 24 hours under load before shipping. Units that fail or show instability are repaired or recycled — they do not ship.
6. Home Assistant Integration: Many D-Central models integrate with Home Assistant, allowing you to control your Bitcoin heater like a smart thermostat — set target temperatures and let the miner scale its power profile automatically.

Every unit ships with a 90-day warranty on D-Central’s conversion work, and the company’s ASIC repair service is available for post-warranty support. This matters: when your Bitcoin heater needs servicing in year two or three, D-Central can repair it. Heatbit customers are locked into Heatbit’s repair pipeline. Canaan customers are dealing with an overseas manufacturer. D-Central’s repair capability is a significant long-term advantage.

All units are assembled and tested in Canada, ship from Laval, Quebec, and are available in multiple colors (Black, Orange, and sometimes White/Gray) to blend with your home decor.

Heatbit: The Mainstream Play (Honest Assessment)

Heatbit deserves credit. They have done more to bring Bitcoin mining heaters into mainstream consumer consciousness than any other company. Their marketing, design language, and consumer-first approach have introduced thousands of people to the concept of dual-purpose mining.

What Heatbit Does Well

• Industrial Design: Heatbit products look like premium consumer electronics. They would not be out of place in a Dyson showroom. This matters enormously for mainstream adoption.
• Simplicity: The app-controlled setup requires zero mining knowledge. No pool configuration, no firmware flashing, no IP scanning. Plug in, connect to WiFi, done.
• Air Purification: The integrated HEPA filter is a unique value-add that no competitor offers. In urban environments or homes with air quality concerns, this is genuinely valuable.
• Safety Certifications: UL certification with tip-over protection gives mainstream consumers confidence.
• Brand Building: Heatbit has successfully positioned Bitcoin mining as a consumer lifestyle product rather than a technical niche hobby.

Where Heatbit Falls Short

• Hash-per-Dollar Value: The Trio at $849 USD delivers 10 TH/s. The D-Central S9 Space Heater at ~$170 USD delivers 13.5 TH/s. The Trio costs roughly 5x more for 26% less hashrate. Even the Maxi Pro at $1,499 USD for 60 TH/s is significantly more expensive than D-Central’s S19 at ~$540–740 USD for 50–95 TH/s.
• Closed Ecosystem: You cannot install third-party firmware, change mining pools beyond what Heatbit offers, or modify the hardware. For Bitcoin maximalists who value sovereignty and self-custody, this is a philosophical problem as much as a practical one.
• Repair Access: If your Heatbit breaks after warranty, you are entirely dependent on Heatbit for repair. There is no third-party repair ecosystem. With D-Central’s open-hardware approach, any qualified ASIC technician — including D-Central’s own repair service — can service the unit.
• BTU Reality: Heatbit’s Trio claims to heat rooms “up to 400 sq ft” but produces only 1,365 BTU/hr. For reference, the US Department of Energy recommends approximately 20 BTU per square foot for primary heating. A 400 sq ft room needs ~8,000 BTU/hr. The Trio delivers 17% of that. The marketing overstates the heating capability.

The Verdict on Heatbit

Heatbit is the right product for the right buyer: someone who values aesthetics, simplicity, and air purification above raw hashrate value. If you are reading this article, you are probably technical enough to set up a D-Central unit and get significantly more hash-per-dollar. But if you are buying this as a gift for a non-technical family member, or your primary criterion is “will my partner complain about how this looks,” Heatbit wins that category hands down.

Superheat H1: The Water Heater That Changes Everything

The Superheat H1, unveiled at CES 2026 in Las Vegas, represents the most significant conceptual leap in Bitcoin mining hardware since the ASIC itself. Here is why.

The Problem It Solves

Space heating is seasonal. In Canada, you need heat for 6–8 months. In Texas, maybe 3–4 months. During summer, your Bitcoin space heater sits idle or becomes an unwanted heat source.

Water heating is year-round. You shower in July just as much as January. A water heater that mines Bitcoin earns 365 days a year, in every climate, with no seasonal downtime.

How It Works

The H1 replaces the traditional resistive heating elements in a 50-gallon electric water heater with ASIC mining hardware. As the ASICs compute hashes, they generate heat. That heat is transferred into the water tank through a heat exchanger, warming the water to standard domestic temperatures. The Bitcoin earned is deposited into the owner’s wallet.

The physics are identical to a space heater miner: every watt of electricity consumed becomes heat. The only difference is the medium (water instead of air) and the delivery mechanism (immersion/heat exchange instead of convection).

The Numbers (As Claimed)

• Price: ~$2,000 USD
• Annual BTC earnings: ~$1,000 (company projection at current BTC prices and difficulty)
• Energy offset: Up to 80% of electricity and water costs (company claim)
• Payback period: ~2 years (company projection)
• Projected lifespan: 10 years

These projections should be treated with caution. Bitcoin mining revenue is a function of BTC price, network difficulty, and electricity cost — all three are volatile. However, even at half the claimed earnings, the economics are compelling for homeowners already running an electric water heater.

Why It Matters for the Industry

If the H1 succeeds, it opens the door to embedding proof-of-work into every heat-producing appliance in a home: water heaters, dryers, ovens, baseboard heaters. Superheat has already announced plans for distributed AI training workloads on future versions. The vision is a network of “micro data centers” embedded within buildings, turning waste heat into infrastructure.

For Bitcoin, it means potentially millions of globally distributed mining units operating invisibly inside water heaters — a decentralization win of enormous proportions.

The DIY Option: Any ASIC Can Be a Heater

Here is a truth the industry sometimes forgets: every ASIC miner is already a heater. The only question is whether you can manage the noise and direct the heat where you want it.

If you already own a miner, or can source one cheaply, you do not necessarily need a pre-built space heater product. You need:

1. A shroud: D-Central’s Universal ASIC Shroud connects your miner’s exhaust to standard 6″ or 8″ ducting, allowing you to route hot air wherever you need it — into a room, through a wall, into a duct system.
2. Silent fans (optional): Replace stock industrial fans with Arctic, Noctua, or Gelid alternatives for residential noise levels. D-Central also sells a SilentMiner Fan Speed Reducer Cable ($4) for a quick noise reduction.
3. A space: A mining closet, utility room, or basement works. Route the hot air duct into the room you want heated, and the cold return air back to the miner.

Popular DIY configurations:

• Mining Closet: Dedicate a closet to your miner, with intake and exhaust ducting to adjacent rooms. See D-Central’s guide: How to Optimize Your Home Mining Space and Layout
• Basement Furnace Supplement: Route miner exhaust into your existing HVAC ducting (consult an HVAC professional first)
• Garage Workshop: An unmodified S19 at 75+ dB is perfectly fine in a detached garage

D-Central offers DIY Space Heater Cases starting at $99.99 CAD for those who want the enclosure without the miner. Bring your own ASIC and build your own heater.

Cost Analysis: Bitcoin Heater vs. Traditional Electric Heater

Let us put real numbers on the central promise of Bitcoin heating. We will compare a standard 1,500W electric space heater against a 1,500W Bitcoin mining heater over 5 years.

Assumptions

• Electricity rate: $0.12/kWh (approximate North American average)
• Usage: 8 hours/day, 6 months/year (180 days — typical for Northern US/Canada)
• Heat output: Identical. Both devices produce ~5,118 BTU/hr at 1,500W. Physics does not play favorites.
• Bitcoin mining revenue: Conservatively estimated at 30–50% electricity cost offset (varies with BTC price and difficulty). We use 40% as our baseline.

The key insight: Over 5 years, the electricity cost is identical because both devices produce identical heat from identical power. The only difference is whether that electricity generates Bitcoin as a byproduct. At a conservative 40% cost offset, a Bitcoin heater pays back $518 over 5 years. A budget model like the S9 Space Heater ($170 USD) achieves full ROI by year 2.

In a bull market with higher BTC prices, the offset can exceed 100% — meaning your heater actually earns more than it costs to run. In a bear market, the offset drops but never reaches zero (as long as Bitcoin has any value at all).

The most important variable is what you do with the Bitcoin earned. If you immediately sell, you realize the fiat value. If you hold (HODL), the future value of those sats is unknowable — but historically, holding Bitcoin over multi-year periods has been extraordinarily rewarding.
