The Economics of Heat-Producing Crypto Mining
The appeal of heating with crypto mining is simple: you pay for electricity you were going to spend on heat anyway, and the mining runs on top and earns revenue that offsets the cost. What follows is how that economics actually works — and what moves it.
One kilowatt, two outputs
Almost all the electricity a mining machine draws leaves as heat, so one kilowatt of power gives roughly one kilowatt of heat — about 24 kWh over a day. The same kilowatt also runs the mining. This is not two kilowatts from one: the electricity is used once, and you capture two forms of value from it — the heat you would have bought anyway, and mining revenue on top.
What drives the return
Two levers move the economics. The first is your power price: cheaper, more renewable electricity leaves more of the mining revenue as net gain. The second is the hardware: a larger upfront investment buys more efficient machines that earn more per kilowatt, so they offset more of the energy cost. Because of that second lever, even where power is not especially cheap, the right configuration can still bring the effective cost of your heat down.
A scale reference
As an illustrative reference, 100 kW of current Scrypt machines produces on the order of 0.35% of one Bitcoin per day at the July 2026 hashprice, settled in Bitcoin. That figure scales with the size of the installation and tracks the market continuously, so it is a snapshot rather than a fixed rate.
Honest caveats
The return is not guaranteed. Mining revenue depends on the live hashprice and the Bitcoin price, both of which change continuously, so any figure is a point in time. That is exactly why we model the exact numbers for each site — power price, heat demand and hardware together. See the full picture on our combined heat & compute page.
Frequently asked questions
Does the return depend only on the power price?
No. Hardware matters too: a larger upfront investment in more efficient machines earns more per kilowatt and offsets more of the energy cost, so even higher-power-price sites can benefit.
Is it a guaranteed return?
No. Mining revenue tracks the live hashprice and Bitcoin price and changes continuously, so any figure is illustrative. We model the exact numbers per site.
How is the mining settled?
In Bitcoin. The mining output is paid out in BTC, which you can hold, convert or reinvest.
