Abstract: Sure nevertheless it’s solely a alternative for area heaters and may by no means change an electrical warmth pump as a result of they’re way more environment friendly. If you happen to 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 adverts for bitcoin miners that may double as area heaters.
However, very similar to photo voltaic panels, all the things they declare is professional 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 dwell in a home surrounded by timber. Every time I’ve requested photo voltaic panel corporations (I’ve solely carried out it twice so it’s a small pattern measurement), they’ve needed to stifle their laughter after they regarded on the maps of our home.
If you happen to’re seeing the adverts, you might be questioning, is it value it?

A Bitcoin Miner is a Sponsored Area Heater
A bitcoin miner is an area heater that generates somewhat little bit of bitcoin. Virtually all of the electrical energy that goes via a bitcoin miner is generated as warmth so it’s as environment friendly as an area heater for producing warmth.
Once you’re serious about the kind of warmth you’re getting, it has all the advantages and disadvantages 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.
Fashionable 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
Once you run a bitcoin miner, you’re solely getting 1 COP. You’re higher off working the warmth pump than the bitcoin miner at virtually each temperature exterior, particularly above 20°F.
💡 Takeaway: Bitcoin miner is an area heater and people are virtually 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 a superb various.
Let’s say you purchase a Heatbit Trio miner, you may anticipate a hashrate of 10 TH/s. The Trio offers you 400W of mining warmth and 1100W of standard 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.
If you happen to 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 decreasing the 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 issue 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 dangerous 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 wish to pursue it, you should purchase the identical computing energy for much less. Heatbit packages it up properly for finish customers however you will get a increased ROI by constructing one your self.
💡 Takeaway: At present costs, which you’ll monitor by way of Minerstat for every gadget, a bitcoin miner with 400W of mining warmth will get you 38 cents a day. If you happen to 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) that you could 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 via 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 problem, 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 brief 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
If you happen to like the concept however don’t wish to spend $1,000, you may construct your individual.
Probably the most comparable methodology is go purchase a used Antminer S9k the place 1300-1400W of energy goes solely 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 much like a vacuum cleaner.
However as a substitute of paying $1,000, you should purchase a used one on eBay for lower than $250.
Then, spend a number of extra bucks to purchase Antminer silencer or dampening kits to minimize the noise. It is best to have the ability to get it to round 50 dB, which makes it akin to the Heatbit Trio. All for lower than $300 or so.
That mentioned, keep in mind that an ASIC miner is NOT a UL-listed area heater. You have to take into consideration security, particularly circuit capability, air flow, and fireplace security that you simply wouldn’t with a shopper area heater.
So you possibly can 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, after I realized that these heater / residence bitcoin miners had been solely producing like 30 cents a day, I misplaced curiosity. 🤣
That stage of ROI isn’t actually well worth the trouble. You’ve got 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 rising the ROI however nonetheless need to take care of the noise.
And when the summer season rolls round, it’s important to resolve whether or not it’s essential 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 may scratch that itch for these of you who wish to tinker. 🤣
