Water heater Floor standing In production

RY3T ONE

A floor-standing heating module from Swiss start-up RY3T: one or two Whatsminer bitcoin miners sit in a dielectric fluid, and a heat exchanger passes their heat into the house's radiators, floor heating and hot water at up to 62–65 °C. The one-miner 7 kW version is listed at CHF 14,921 and the two-miner 14 kW version at CHF 17,990, before installation; the data sheet gives 190 TH/s at 5.5 kW per miner in normal mode. You reserve with a refundable CHF 1,000 deposit and get a final quote after a site visit; partner firms install it in Switzerland, Germany and Austria.

*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 (data sheet: 190 TH/s per Whatsminer M56S+ in normal mode, and an owner's unit installed in January 2025 had two M56S+; RY3T's Oct 2025 calculator uses 220 TH/s for an M56 at 5.5 kW; the contract names a Whatsminer M56, the 2023 how-it-works page an S19 Pro, and the fitted miner varies); power (data sheet: 5.5 kW per miner in normal mode; the version is sold as '7 kW', its maximum); efficiency (not published as a spec; the data sheet figures give about 29 J/TH, while the Oct 2025 calculator assumes 22.6 J/TH 'with autotuning'); hashrate versions (14 kW figures are twice the data sheet's per-miner values); store listings price (order page lists CHF 14,921, but RY3T's Oct 2025 calculator models CHF 17,910 per unit and CHF 15,000 installation; the contract reserves price changes and the final price is quoted); store listings taxIncluded (contract says 'exkl. MwSt.' in clause 1 and 'inkl. Mehrwertsteuer für die Schweiz' in clause 4.1); store listings shipsFrom (RY3T is based in Wil, CH and says it delivers the unit in person; the first units were built in Romania); weight (80 kg empty; 105 kg filled; both carry a '**' mark with no footnote in the data sheet, which RY3T says may still change); dimensions (from the Jan 2024 data sheet, issued during testing; the unit is hexagonal, so w and d are the stated diameter); noise (sound power level '<40 dB'; no sound pressure figure); operating temperature (only a storage and transport range of -20 to +60 °C is published); features (max flow temperature: data sheet 62 °C, order page 'bis 65°'); where it's made (Romania per the Sept 2024 post on the first production run; later batches not confirmed); production status (the first customer units went online in January 2025, later than the planned October 2024, according to an owner's reports on Stacker News and to startupticker.ch, which counted over 35 orders by then; RY3T says over 40 were installed by Jan 2026, and East Digital (Sept 2026) says more units followed in private homes but gives no number; RY3T AG is still active in the Swiss commercial register; but ry3t.com now redirects to the NOVA product, the ONE is sold only by reservation and quote, and no outside source gives a 2026 delivery figure. The 'August 2026' delivery date on RY3T's site is for the NOVA, not the ONE); colours (renders show brushed metal and black finishes with red LED trim; no colour options listed); SKU; launch date (2024-09 is when RY3T opened pre-orders; the first customer units went online in January 2025, according to an owner report and startupticker.ch); cooling (immersion in Bitcool according to RY3T and an owner's January 2025 photos; a RY3T product lead wrote in 2026 that immersion brought maintenance and leakage risk and that the team later moved toward water cooling for a longer-term design, so later units may differ).
