Space Heater BTU Calculator
Heat Output Formula
Nearly all miner electrical input becomes heat. A practical estimate is watts multiplied by 3.412 to convert to BTU per hour, then adjusted for room size, airflow, insulation, season, and whether the heat offsets another heating source.
Separate Heat From Mining Revenue
Recovered heat can improve a cold-room decision, but it should be modeled separately from mining revenue. The setup still needs safe electrical capacity, ventilation, noise control, and a shutdown plan.

Bitcoin miner cost is electricity only. The miner also earns Bitcoin while heating your space.
Did you know?
All electricity consumed by a miner is converted to heat. A 1,400W miner produces the same heat as a 1,400W space heater — but also mines Bitcoin. Browse our Bitcoin Space Heaters to find a dual-purpose mining heater for your home.
Methodology
This calculator converts electrical power into useful heat output and estimates heating offset.
- Heat output is calculated as watts x 3.412142 BTU/hr.
- Cost and offset estimates use your electricity rate, heating-season assumptions, and entered fuel prices.
- Actual savings depend on insulation, airflow, heating-system efficiency, and local climate.
Data sources: user inputs, network or market data available on the page, manufacturer specifications, and the displayed assumptions. Verify results before making financial or electrical decisions.
Fuel prices vary significantly by region, supplier, and season. Natural gas, oil, and propane conversion factors are industry averages and may differ from your actual heating system efficiency. This calculator provides estimates for comparison purposes only.
