But once you set up your device, Heatbit will track and deliver your mining earnings to your phone, even if you don’t have a bitcoin wallet yet. After reaching the minimum transfer amount of 100,000 satoshi, or one thousand bitcoins ($66 at April 2026 prices), you can transfer this to your wallet and, possibly, spend it. Heatbit software is compatible with Lightning networks and major exchanges (Coinbase, Binance, OKX, BitFinex).
Unlike most air purifiers that only turn on when there are air quality problems, the Heatbit continues to pump air through its HEPA filter while the extractor and heater are active. Although Heatbit recommends replacing the filter once every six months, in practice, the software showed that the filter was being used by about 1 percent per day. For whatever reason, my Heatbit app refused to believe I wasn’t in Seattle, and so my outdoor air quality reading was tied to King County, Washington.
Advances aside, the ease of onramp is great for a device not aimed at crypto-enthusiasts. At current prices, if I ran my heater/extractor non-stop, this would save me about $70 to $100 off my heating bills once every two months. Pretty cool, right?
Why the Math on the Heatbit Doesn’t Work with the Pencil

But here’s the problem with that calculation. I would also need to pay at least $1,500 up front (the current discounted price of the Maxi Pro) before I would have access to these savings. This is about $1,350 more than The best space heaters I’ve tried. It’s also about $900 or $1,000 more than the combination purifier-heater from Dyson. So your savings calculation needs to take this upfront cost into account.
At this rate, assuming my energy costs and bitcoin prices stayed constant, it would take me between five and eight years to “make my money back” in bitcoin if I ran this thing 24/7 for four months a year. That is on a device with a one year warranty. (The founders of Heatbit say there has only been a failure rate in the “low numbers” after three years for the first generation. Heatbit Trio.)
These numbers assume I could run the space heater non-stop on full blast for several months as the primary heat source—which is not how most people use space heaters. I only turn on the space heater when I’m in the room, and point it at me. For heating the whole house, natural gas or a heat pump both are the most cost-effective options, if available.
But let’s say you only have thermal electricity. And you would always be running the space heater. And let’s assume Heatbit continues to work with the same efficiency for at least five years. Is Heatbit now the best option, economically? Well, still maybe not.
Every Crypto Miner Is A Heater
Every crypto mining device will heat up your house, whether its developers advertise it as a space heater. Each miner will produce heat at 100 percent efficiency, depending on how much power it uses. That’s because one way or another, all waste energy will eventually be converted into heat.
The best combination space heater and bitcoin miner will always be the one that mines bitcoin the most efficiently. At that time, you can only take it Canaan Avalon Q ($1,900) and get 50 percent of the optimal hash rate and generate the same amount of heat. Newfangled ASIC (Application-Specific Integrated Circuit) miners can give you better performance. Anything you use, at the same power level, will generate a lot of heat.
