All three let you mine bitcoin at home. The real differences are how much heat you get, where it goes, and how the system installs. Competitor figures below are as their makers list them, checked in November 2026.
| Product | What it heats | Power | Hashrate | Noise | Price | Setup |
|---|---|---|---|---|---|---|
| Heatbit Trio | A room, up to 400 sq ft | Not stated per model | 10 TH/s | 45 dB | $849 | Plug in |
| Heatbit Maxi | A room, up to 400 sq ft | 1,500 W | 35–39 TH/s | 56 dB | $1,249 | Plug in |
| Heatbit Bitwater (preorder, ships Q1 2027) | A water heater tank, as an element | Up to 600 W | Up to 34 TH/s | No fans | $949 first batch, later up to $1,299 | Fits a 1" element port; 110–240 V controller |
| Braiins Mini Miner (BMM 101) | Not a heater: a desktop solo miner | 40 W (80 W overclocked) | 1.0 TH/s | ~40 dB | $299 | Standard outlet |
| Hashrate House Aqueon Hydro | Hot water, radiant floors, forced air | ~4,180 W (rated 5 kW) | ~210 TH/s | 34 dB | $6,000, free U.S. shipping | 240V, 30A outlet; plumber connects it |
| Hashrate House HashTub | A hot tub, or a home's heating | ~4 kW | Pleb (24 J/TH) or Pro (17.5 J/TH) | ~34 dB | $3,895 or $4,395 | 240V circuit; Snorkel tub, retrofit, or home install |
Which fits?
- To warm one room with a plug-in heater: Heatbit's room heaters are built for that. Heatbit listed its room heaters as sold out for the season when we checked.
- To solo mine on your desk for very little power: the Braiins Mini Miner. Braiins OS and Braiins Pool are software and a pool for miners you already own.
- To heat your hot water, floors, or a hot tub with several kilowatts of heat: Hashrate House. The Aqueon and HashTub make roughly three times the heat of a 1,500 W room heater and many times the hashrate of a small heater or desk miner, and they need a 240V circuit to do it.
