Gas Fan Heater Cost & CO2

Estimate the gas cost and CO2 emissions of a gas fan heater from its consumption and running time. Works with city gas and LPG, and can convert from heating output (kW).

How it works

  • Gas cost is estimated as 'gas consumption (m³/h) × hours per day × days used × gas unit price (per m³)', and CO2 emissions as 'gas used (m³) × CO2 emission factor'.
  • Representative CO2 emission factors are used: about 2.23 kg-CO2/m³ for city gas and about 6.0 kg-CO2/m³ for LPG (propane). Actual factors vary by gas supplier and composition.
  • When heating output (kW) is entered, consumption is converted with 'm³/h = kW × 3.6 ÷ heating value' using representative heating values (city gas 13A about 45 MJ/m³, LPG about 100 MJ/m³).
  • Gas consumption and heating output can be found in the product spec sheet. Entering the per-unit gas rate from your bill improves accuracy.
  • Gas prices, unit rates, and emission factors vary widely by country and region, so enter your local values for a more realistic estimate.
  • Results assume continuous operation at a fixed output. In practice, automatic control adjusts consumption based on room temperature, so treat the figures as a rough guide.
  • All figures are approximate. For exact charges and environmental impact, check the billing information from your gas supplier.
