Turn surplus solar, wind, hydro or biogas power into mining income — and put the heat to work where your site can use it. Start with the energy you actually have, then test the numbers.
Different renewables. Different operating patterns.
The strongest starting point is electricity that is genuinely surplus, export-constrained or poorly rewarded, combined with a realistic operating profile. Mining is one option alongside export, storage and other on-site uses.
SOLAR
Make use of the daytime surplus.
Size around usable generation after farm or business demand. Summer power and winter heating rarely line up perfectly; use annual generation data and count storage costs.
WIND & HYDRO
Work with a changing resource.
A controllable load can follow available output. Check seasonal flows, curtailment arrangements and connection limits before choosing how much hardware to install.
BIOGAS & CHP
Add a local electricity customer.
Farm digestion can offer a steadier operating profile. Separate CHP engine heat from miner heat, and assess existing heat uses before adding another system.
ALL MINERS / HIGHEST EARNINGS FIRST
Find a miner that fits your renewable power.
Compare all catalogue miners across algorithms, ordered by highest gross daily earnings for your site inputs. Filter by algorithm, cooling or availability, then select a row to see energy use, its earning asset and the export comparison.

Check the highlighted inputs. Figures are paused until all values are within range.
All catalogue miners, highest gross daily earnings first for your site inputs. Each estimate uses the highest-earning available asset or service for that miner.
A fixed-rate illustration, not a forecast. Annual figures repeat these hours and rates for 365.25 days; use an annual-average operating profile. Excludes tax, financing, depreciation, repairs and any costs you have not entered. No flexibility payments assumed.
Gross p/kWh uses miner electricity only; site kWh and gain include your auxiliary-power allowance. All miner algorithms are included. Each estimate uses the highest-earning available 24-hour asset or service, labelled in its row. Alternative coins are not added together; NiceHash values are labelled as BTC-equivalent. Rows without estimates remain visible. Default order is highest gross £/day for your site inputs; miners outside the power budget have no modelled income. See the calculation method.
AGRICULTURE / RECOVERED HEAT
Let the heat do another job.
From growing spaces to suitable process heat, the opportunity starts with a real demand at the right temperature. Explore the applications and the evidence.
The Lurgan farm and Lent Hill examples show why a local electricity user can matter. Their plant capacities and reported project status are recorded in the archive.
GROWING
Greenhouses and propagation.
Mining heat can supplement greenhouse heating, but crops still need stable temperatures, humidity management and backup heat. Pilots and modelling are labelled separately.
PROCESSING
Drying and low-temperature process heat.
Firewood drying is documented; crop drying and boiler preheating need process-specific design. Food hygiene, airflow and final moisture targets determine whether heat is useful.
DESIGN THE HEAT USE FIRST
Where could the heat work for you?
Start with the receiving process: how much heat it needs, at what temperature, at what time of year and how far it is from the miners. Air, hydro and immersion cooling offer different routes to capture it.

Lent Hill Ag-Grid Digital uses electricity from manure and food-waste digestion to supply a flexible mining container. The operator reports a 300 kW grid-export limit alongside a 1 MW mining unit.
Application lesson. Separate engine output, site demand and permitted export when sizing a flexible load.
Evidence limits. Ag-Grid describes crypto mining without naming the mined asset. The account explains how the electricity is used, but does not establish Bitcoin earnings or recovery of heat from the miners.
Irish Farmers Journal visited Tom Campbell’s anaerobic-digestion site and its Scilling Digital Mining installation. The project uses stranded electricity beside a farm biogas plant.
Application lesson. A farm can add a local electricity buyer where export capacity is constrained.
Evidence limits. This account comes from a December 2022 site visit. The 500 kW figure is the AD plant rating, and the report does not measure heat recovered from the miners.
Bitcoin Brabant describes moving industrial miners into a hydrangea greenhouse where heat was useful. Its retrospective explicitly says the family-run greenhouse operation ceased in 2023.
Application lesson. Cheap electricity and a nearby heat customer must coincide for the business case to work.
Evidence limits. The greenhouse operation ceased in 2023. The retrospective describes an earlier pilot and says that only a few of the enquiries led to worthwhile installations.

Genesis Mining and Swedish research and municipal partners developed a demonstration linking a mining container with a greenhouse. The project explored local food production using recovered heat.
Application lesson. Crop humidity, ventilation and winter design temperatures matter alongside available heat.
Evidence limits. Greenhouse area and scale-up figures are design or modelling claims, not evidence of annual commercial crop yields. Fish, algae and insect farming are discussed as further applications.
Canaan announced a 24-month proof of concept with Bitforest. Heat from liquid cooled Avalon equipment would preheat greenhouse boiler intake water through a separate heat-exchange loop.
Application lesson. Preheating can complement an existing boiler while preserving its ability to meet peak demand.
Evidence limits. Delivery was conditional on notice to proceed. The 90% heat-capture estimate and 95% uptime are targets; the filing says actual performance will be confirmed after full operation.

SAIHEAT’s annual report describes a Bitcoin-mining operation in Marietta and greenhouse and fish-pond facilities heated with recovered hot water. Earlier filings also describe an Ohio demonstration facility.
1 MW computing unit · 5,000 ft² greenhouse (2024 report)
Application lesson. Water loops let heat serve more than one nearby agricultural use.
Evidence limits. The company filing documents the deployment. It does not establish commercial fish yields, crop profits or an entirely renewable electricity supply.
MARA reports supplying heat at 55–78°C into an existing district heating network. At milder times, those temperatures allow direct integration without heat pumps.
Application lesson. Match the heating network’s seasonal flow and return temperatures before selecting equipment.
Evidence limits. Operator-reported output, not an independent measurement by The Mining Shop. Carbon-free electricity is not necessarily all renewable.
Application lesson. Include booster electricity and backup plant in the economics of higher-temperature heating.
Evidence limits. Heat-pump output and miner heat must be accounted for separately. Published figures are a site example, not a temperature guarantee for every hydro miner.
Sazmining describes a 2.5 MW site serving a former hospital converted into a business centre. Separate water loops transfer heat to the building, with backup heating retained.

GDA reports a heat-repurposing collaboration with Muttern Fastigheter that supplies hot air to local buildings using electricity described as hydroelectric.
A Norwegian site report describes Kryptovault directing warm air into containers of firewood for producer Varma. The report identifies a practical drying partnership beside the mining operation.
Application lesson. A nearby drying business can use warm air without needing a higher temperature steam system.
Evidence limits. The January 2022 visit records the arrangement at that time; it does not confirm current operation. Firewood drying conditions cannot be transferred unchanged to food or grain.
MintGreen’s TUMBLER immersion system is designed for Shelter Point Distillery’s whisky barrel-ageing process. Heat can transfer from the cooling fluid to air or a separate fluid circuit.

Gridless describes revenue sharing agreements for otherwise unsold renewable electricity. Its controls reduce mining demand when other customers, such as water pumps or maize mills, need the power.
Application lesson. Give productive local demand priority and use mining as a flexible residual buyer.

Ponderay Industries reported that Merkle Standard began operating a mining data centre at its paper-mill campus in 2022. The mill had entered bankruptcy in 2020 and was acquired in 2021. This is a reuse of industrial land and power infrastructure, rather than evidence of paper waste being converted into mining fuel.
Application lesson. Investigate the value of an existing industrial connection, buildings and heat demand before assuming a new power plant is necessary.
Evidence limits. Mill restart plans, mining operations and later AI infrastructure plans are different activities. Infrastructure ratings and regional hydropower shares do not establish continuous mining demand, direct renewable supply or project profitability.
Terahash says its Genesis site went live on 31 October 2024. The 1 MW installation supplies heat to a district network serving industrial and residential demand, with electricity described by the operator as renewable.
Application lesson. A nearby heat buyer can be as important to site selection as a competitive electricity contract.
Evidence limits. The source does not publish an audited annual heat balance or a complete project cash flow. A town’s population is not the number of homes heated by this installation.
Terahash documents a car wash using a 150 kWp PV canopy and up to 20 kW of water cooled mining. Heat serves wash water and winter floor heating. A 2,000-litre hot-water tank and a secondary heat pump help manage demand.
Application lesson. Year-round washing demand can offer a useful heat destination, while a heat pump covers conditions that do not favour mining.
Evidence limits. The promotional revenue range is not a current price quote or measured annual profit. Solar nameplate capacity does not establish the share of mining electricity supplied by solar over a year.
In November 2024, Deutsche Telekom announced a pilot with Bankhaus Metzler at RIVA Engineering in Backnang. Metis Solutions hosts the container and Telekom MMS operates the miners. RIVA has on site photovoltaic generation. The purpose is to collect field evidence for flexible use of surplus electricity.
Application lesson. Instrument a pilot before scaling: record the surplus, export alternative and actual response of the mining load.
Evidence limits. The announcement is not a published operating-results dataset. It does not establish miner capacity, realised returns, grid-service payments or a heat reuse installation.
SunBit describes a 2024 installation in a 3,000 m² industrial hall. Mining heat works alongside an air-to-water heat pump, reducing reliance on oil. The site also has a 30 kW solar array.
SunBit identifies Lekkum as its first international project in 2025. A local team installed a Bitcoin Boiler to replace gas heating at a commercial property.
Application lesson. A local installer and clear service responsibilities matter when integrating specialist computing equipment with an existing heating system.
Evidence limits. The source does not give the miner capacity at this property, an annual energy balance or an independently verified financial return.
SunBit reports fitting a Bitcoin Boiler alongside the oil boiler in a 200 m² Kotka home. An outdoor unit rejects unwanted summer heat and allows additional use of solar surplus.
Application lesson. Hybrid heating can preserve resilience while allowing mining to run only when heat demand or electricity economics justify it.
Evidence limits. The published reference is not a metered annual cost comparison. Keeping an oil boiler does not establish how often either heat source operates.
Terahash describes a commissioned system at Nebona’s spice factory: a Heatcore HS20 with two Whatsminer M63 units uses surplus rooftop solar power and supplies hot water to a buffer tank. The existing heating system remains available.
Application lesson. Separate useful building heat from production-process requirements, and prioritise the factory’s productive electricity demand.
Evidence limits. The reference describes building and hot-water integration, not proof that mining heat runs every spice-processing stage. Its historical mining-revenue range is guidance, not a guaranteed yield.
Terahash describes Kläger Group’s Hartha energy park with a 1.6 MWp solar array, a 350 kWh battery and a mining container able to absorb up to 500 kW. The container is intended to buy surplus left by industrial production, with storage and grid export also available.
1.6 MWp solar · 350 kWh battery · up to 500 kW mining
Application lesson. Compare mining, storage and export using the value of the same surplus electricity at the same time.
Evidence limits. Power and stored energy are different quantities. The source does not publish a full dispatch dataset, annual profit or an independently verified saving. Heat recovery is not documented in this reference.
Bathhouse says it began a pool-heating mining pilot in 2022. Its technical explanation describes immersion-cooled ASICs, a dielectric-fluid circuit and heat exchangers that transfer heat into pool plumbing. The comparison is with its previous electric resistance heaters.
Application lesson. A steady pool-heating load can use mining heat for longer than seasonal space heating, provided recovery and water-system separation are designed correctly.
Evidence limits. The comparison with resistance heating does not show that mining uses less electricity than a heat pump. The operator’s account concerns its own installation and does not establish a payback period for other pools.

CALCULATION NOTES
Understand the value of a kWh.
Power is kW. Energy is kWh. A 3 kW miner running for six hours uses 18 kWh before external pumps or cooling. Effective hours equal scheduled hours × availability. The power budget includes your auxiliary allowance.
Gain vs export = mining after pool fee + useful heat credit − export forgone − extra energy costs − other entered running costs
Keep the comparison consistent. Export forgone uses all electricity consumed by the installation, including auxiliary loads. The model assumes that energy could earn your entered export rate. For genuinely curtailed electricity with no alternative buyer or curtailment payment, enter zero. Where only part can be exported, model those hours separately.
Heat credit is an avoided cost, not extra electricity. Useful heat is miner electricity × the useful-heat percentage. That percentage includes recovery losses and whether demand exists at the time. Apply the cost of the heating you actually displace; do not count both heat-sale revenue and an avoided fuel bill for the same heat.
Dates and limitations. Earnings reuse the shop’s underlying mining data service across all miner algorithms. For each miner, the highest available 24-hour earning asset or service is selected and labelled; alternative assets are not added together. NiceHash is labelled as a BTC-equivalent valuation. Missing estimates remain unavailable rather than being treated as zero income. The source timestamp is shown for the selected miner. Future coin prices, network difficulty, reward halvings and hardware degradation are not forecast. Stock and listed prices can change. Installed costs and export-contract terms require a site-specific quote.
PRACTICAL QUESTIONS
Before you build.
Does renewable electricity make mining free?
No. Electricity may have an export value, and the installation still has purchase, cooling, maintenance and operating costs. Even genuinely curtailed power does not make the equipment free.
Can the miners follow solar or wind production?
A suitably designed control system can reduce or stop mining when surplus power falls. The table uses an average operating schedule; a real design needs half-hourly or finer generation data, restart behaviour and a site-load priority policy.
Does one kWh of electricity give one useful kWh of heat?
Nearly all miner electricity eventually becomes heat, but less may be delivered usefully. Capture losses, temperature, pipe or duct losses, seasonal demand and backup operation decide the usable share. A miner is an electrical heat source; it does not multiply heat like a heat pump.
Can I replace a farm boiler with mining heat?
Sometimes it can supply a suitable base load or preheat stage. Preserve backup heat for outages and power-limited periods. High-temperature steam, sanitation and specialist processes may need a booster or a separate heat source.
Are these all proven Bitcoin projects?
No. The archive explicitly separates operator accounts, site visits, demonstrations, proposals and research. The Lent Hill source describes crypto mining without naming the asset; that limitation is recorded. Financial outcomes are not guaranteed or copied into the calculator.
What should I send for an assessment?
Your generation and export profile, import and export prices, connection limits, site location, available space, heat demand and temperatures, plus your budget. For seasonal renewables, a full year of half-hourly data is much more useful than a single sunny-day output.
