Abstract: Sure nevertheless it’s solely a substitute for area heaters and may by no means change an electrical warmth pump as a result of they’re much more environment friendly. In the event you can tolerate the additional work, noise, and trouble, a bitcoin miner could also be a enjoyable technique to generate warmth and bitcoin as a small rebate.
Each winter, I see tons of Fb advertisements for bitcoin miners that may double as area heaters.
However, very like photo voltaic panels, all the pieces they declare is official however the query is whether or not it’s value it for the upfront price and trouble.
I’d like to get photo voltaic panels however we stay in a home surrounded by bushes. Each time I’ve requested photo voltaic panel firms (I’ve solely achieved it twice so it’s a small pattern dimension), they’ve needed to stifle their laughter after they appeared on the maps of our home.
In the event you’re seeing the advertisements, chances are you’ll be questioning, is it value it?

A Bitcoin Miner is a Sponsored Area Heater
A bitcoin miner is an area heater that generates a bit little bit of bitcoin. Nearly all of the electrical energy that goes by a bitcoin miner is generated as warmth so it’s as environment friendly as an area heater for producing warmth.
While you’re fascinated by the kind of warmth you’re getting, it has all the advantages and downsides of an area heater. Good localized warmth, noisy, and much much less environment friendly than a warmth pump.
Area heaters have a coefficient of efficiency (COP) of 1. One unit of electrical energy generates one unit of warmth.
Trendy warmth pumps have a COP better than 1 so that they’re as a lot as 3.5x extra environment friendly relying on the surface temperature (which is the place it attracts warmth):
- 45°F will get you ~3-3.5 COP
- 32°F will get you ~2.5-3 COP
- 25°F will get you ~2 COP
- 15°F will get you ~1.5 COP
- 5°F will get you ~1.2 COP
While you run a bitcoin miner, you’re solely getting 1 COP. You’re higher off operating the warmth pump than the bitcoin miner at nearly each temperature exterior, particularly above 20°F.
💡 Takeaway: Bitcoin miner is an area heater and people are nearly at all times much less environment friendly than a warmth pump, however they do supply localized heating. So if you happen to’re solely going to warmth a small space, a bitcoin miner could also be an excellent various.
Let’s say you purchase a Heatbit Trio miner, you’ll be able to count on a hashrate of 10 TH/s. The Trio provides you 400W of mining warmth and 1100W of normal resistive warmth (it’s additionally air air purifier too). I’m a novice in terms of bitcoin miners however in keeping with Minerstat, 10 TH/s nets you about 38 cents a day.
In the event you run it 24/7 and it’s a 1500 Watt gadget, we’re speaking 36 kWh/day which in Maryland will price me round ~$8.07 (sure, we pay 22.4 cents a kWh all in 😝). The bitcoin makes 38 cents, thus lowering the associated fee by round 4.7% for simply the one miner.
On the time of this writing, bitcoin was $89,027.55 a coin (and mining problem was close to cycle highs).
From an ROI perspective, we’re speaking $139 a 12 months on a $999 gadget, so a return of 13.9% which, to be sincere, isn’t that unhealthy for a mining rig, heater, and air air purifier. It does assume that you’d’ve paid for electrical resistance warmth anyway although and isn’t a standalone return.
And if you happen to actually need to pursue it, you should buy the identical computing energy for much less. Heatbit packages it up properly for finish customers however you may get a increased ROI by constructing one your self.
💡 Takeaway: At present costs, which you’ll monitor through Minerstat for every gadgeta bitcoin miner with 400W of mining warmth will get you 38 cents a day. In the event you pay $999 for a tool, it’s a 13.9% ROI plus 1500W of warmth.
A Bitcoin Miner is Loud
Bitcoin miners are loud as a result of they’ve followers cooling the processors – which is the place you get your warmth. Area heaters are loud too although.
The Heatbit Trio claims it’s about 40 dB, which places it as loud as a fridge. It’s loud sufficient so that you can discover however regular sufficient (no revving up) which you can have it mix in as background noise. You’ll be able to mitigate a few of the noise by placing it on a vibration dampening mat or placing the machine elsewhere and directing the warmth to the place you might be positioned by piping, however the noise will nonetheless be a difficulty.
I’ve a small Lasko area heater beneath my desk and a decibel monitoring app tells me it’s round 40 dB about three ft away. The Heatbit Trio is nearly as loud as your common small area heater.
Extra highly effective miners, like some iPollo or Antminer, are considerably louder. The iPollo V2 model is round 75 dB, which has similarities to a loud vacuum. The house miner model, iPollo V2, is round 50 dB which has similarities to rain or a house fridge.
There Are Quieter Miners
Since noise is a giant subject, there are miners which can be designed to be like baseboard heaters such because the Canaan Avalon Mini3. Right here’s a video reviewing it.
The quick reply is that it’s 800W of mining energy for 37.5 TH/s that will get you round $1.30-$1.60 a day (if you happen to run it 24 hours) earlier than the price of electrical energy. It’s by no means worthwhile, however like Heatbit or others, it subsidizes your electrical energy with bitcoin. It’s additionally round $900.
The right way to Construct Your Personal Bitcoin Heater
In the event you like the concept however don’t need to spend $1,000, you’ll be able to construct your individual.
Essentially the most comparable methodology is go purchase a used Antminer S9k the place 1300-1400W of energy goes totally to mining. This will get you 13-14 TH/s which is nice for ~50 cents a day. It’s loud although, 75 dB, so just like a vacuum cleaner.
However as an alternative of paying $1,000, you should buy a used one on eBay for lower than $250.
Then, spend a couple of extra bucks to purchase Antminer silencer or dampening kits to reduce the noise. You need to be capable of get it to round 50 dB, which makes it akin to the Heatbit Trio. All for lower than $300 or so.
That mentioned, do not forget that an ASIC miner is NOT a UL-listed area heater. It’s worthwhile to take into consideration security, particularly circuit capability, air flow, and fireplace security that you simply wouldn’t with a client area heater.
So you would get three Antminers for the worth of 1 Heatbit. You simply want to determine how you can set it up and hook it as much as generate bitcoin.
A Bitcoin Miner is a Novelty
To be sincere, once I realized that these heater / residence bitcoin miners have been solely producing like 30 cents a day, I misplaced curiosity. 🤣
That degree of ROI isn’t actually well worth the trouble. You could have the up-front price plus the noise air pollution of the miner itself. Even if you happen to went homebrew and bought Antminers, you’re growing the ROI however nonetheless should take care of the noise.
And when the summer season rolls round, it’s important to determine whether or not it is advisable add ducting to pump the warmth out of the house or shut off the gadgets.
For me, the novelty isn’t fairly sufficient to justify the up-front price, noise, and complexity… however I can see why it might scratch that itch for these of you who prefer to tinker. 🤣
