Mining-as-Heating Savings Calculator: Is Your Bitcoin Miner a Free Space Heater?

Method: An ASIC is a ~100%-efficient resistive heater: every kWh it draws becomes ~1 kWh of heat. During heating season that heat offsets heat you would otherwise buy. The offset value per kWh of mining electricity equals your heating cost per kWh-thermal — for electric resistance that equals your electricity rate (so net winter cost ≈ $0); for a cold-climate heat pump it's your rate ÷ COP (a seasonal COP of ~2.2 makes the pump ~2.2× cheaper per unit of heat, so mining heat is pricier); for gas, oil, propane, pellets and cordwood it's that fuel's delivered per-kWh cost. Pick your province and the electricity rate and current-fuel cost auto-fill from our provincial heating fuel index (single-sourced; you can still override any field). Outside heating season there is no offset. Estimates only — not financial advice. See the heat-reuse glossary entry and D-Central's Bitcoin space heaters.
