Hashrate House Aqueon Hydro System

A round black cabinet, 24 in (610 mm) across and 10 in (254 mm) tall, that sits under a home water heater and holds a water-cooled Whatsminer M64 bitcoin miner (210 TH/s at about 4.2 kW). Two built-in heat exchangers pass its heat to the hot-water tank and, if wanted, to a radiant-floor or furnace-coil loop at up to 176 °F (80 °C); it plugs into a 240 V NEMA L6-30 socket and is run from a web control page. Hashrate House lists it at $6,000 with the miner and free shipping in the contiguous US, but Buy Now takes a $3,000 deposit for a unit built in 2-4 weeks, and it is sold as an experimental product that is not UL listed.

*What a pool would pay on average at today's difficulty, block reward and bitcoin price, before pool fees. Solo miners usually earn nothing, and very rarely a whole block. A plain electric heater turns the same electricity into the same heat, so the mining income is what makes the difference.

Payback is how long the bitcoin a device earns takes to add up to its price. It leaves out electricity, which buys the heat: compare earnings per kWh with your electricity price to see whether mining alone covers it. It uses the average of the last 3 months, to 12 Nov 2026: bitcoin at $79,558, 969 EH/s on the network and 3.15 BTC a block, less a 2% pool fee, for the hours you set. It cuts the block subsidy in half at each halving, the next around Apr 2028, and otherwise assumes those carry on unchanged, which they won't. Income at today's difficulty and price is about 17% below that average. Hashrate usually rises, though miners that stop paying after a halving may switch off, which leaves more for the rest. How we work it out.

Sources and data notes

Not yet confirmed from the maker's own documents: hashrate (210 TH/s is the maker's 'tested' figure; MicroBT rates the M64 at 180–206 TH/s ±10%, and the maker's customer-install screenshot shows 202.6 TH/s at 4,131 W); power (about 4,180 W is simply 210 TH/s × 19.9 J/TH, so it seems to cover the miner alone, not the pump and controller; the unit is rated 5,000 W, the support FAQ quotes '19.9 J/TH at 5,000 W', and the checkout says '3–5 kW thermal output'); hashrate versions (the M74 upgrade is priced only 'at market'; the calculator names it an M74S+ and estimates $8,000, and the support FAQ says 'closer to 12 J/TH'); heat modes (no hashrate is published for high-power mode, whose draw depends on the supply voltage); dimensions (the photos show the port stubs sticking out of the side, which the 24 in figure may not include); weight (not published, empty or filled; the load rating is given only as 'a full water heater'); noise (the support FAQ says the maker's hydro and immersion systems run below 30 dB; a general claim, not a measured Aqueon figure); operating temperature (the manual asks only for an indoor, conditioned or freeze-protected space); frequency (not published); where it's made (designed and assembled in the USA per the maker; the M64 miner is made by MicroBT of Shenzhen, China); production status (set to in-production, as for the made-to-order HashTub: the terms say every system is built to order, the checkout promises ship-out about 2-4 weeks after the deposit, and the maker shows a customer install; but Buy Now is titled 'Pre-Order Deposit Payment', the manual is an initial release dated 29 October 2026, and the number of units shipped is not published); launch date (not published; the manual is an initial release dated 29 October 2026 and maker blog posts mention the Aqueon from 13 October 2026); store listings (the $6,000 is the listed full price; the checkout charges a $3,000 deposit, and the terms say the balance is due before production and shipping costs may vary, although the product pages promise free shipping in the contiguous US); images (value-basement-install.webp and installation.webp look like computer-generated scenes rather than photos of real installs; only customer-install-ui.webp is captioned as a customer install); colours (black, from the maker's photos; no colour options are published); SKU (none published).
