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).
Input
Gas type
How to enter gas consumption
Check the "gas consumption" field on the product spec sheet.
Entering the per-unit rate (per m³) from your bill improves accuracy.
Result
Gas cost for the period (City gas)
$9,600.00
CO2 emissions (period)
133.8 kg
Total gas used (period)
60 m³
Gas cost per day
$320.00
| Item | Per day | Period total |
|---|---|---|
| Gas consumption | 2 m³ | 60 m³ |
| Gas cost | $320.00 | $9,600.00 |
| CO2 emissions | 4.46 kg | 133.8 kg |
Estimated at about 0.4 m³/h gas use and a CO2 factor of 2.23 kg-CO2/m³
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.
