Home energy
Could a Bitcoin miner heat your home for less?
A miner turns essentially all of the electricity it draws into heat, just like an electric radiator — except it also earns Bitcoin while doing it. Pick your town, describe your home, and see how the numbers compare with gas, a heat pump, reverse-cycle air conditioning and other options.

Heating sources to compare against
Bitcoin network
Difficulty is assumed constant for a year. It has historically risen, which reduces future revenue.
Methodology and assumptions
Heat demand
Daily mean temperatures come from the ECMWF ERA5 reanalysis via Open-Meteo and are averaged over three years. Heating degree days use max(0, base − mean temperature). Building heat loss is estimated from floor area and insulation, then calculated as UA × degree days × 24 ÷ 1000 kWh.
Miner heat and revenue
A miner converts effectively all electrical input into heat. Heat-led mode runs only when that heat can be absorbed; always-on mode counts surplus heat as wasted. Expected BTC earnings use hashrate, network difficulty, block subsidy, recent fees, uptime and pool fee. Price, difficulty and fee data come from mempool.space.
Energy prices and comparisons
Eurostat household averages prefill electricity and gas where available. Other locations and fuels require your own tariff. Each reference cost divides annual heat demand by efficiency or seasonal COP, then applies the fuel price. The miner scenario subtracts mining revenue and adds any backup heat cost.
Not modelled
The estimate excludes installation, noise mitigation, ventilation, time-of-use tariffs, hardware failure, maintenance, resale value, tax treatment and future changes in Bitcoin price or difficulty. Treat it as an order-of-magnitude comparison, not financial or engineering advice.
