Extrapolate the Consumption of a Gas Heater
Calculator how much a gas-fired heater consumes approximately depending on the size of the heated room. Around 16 cubic meters of gas are required for heating and hot water per year and square meter of living area. Without hot water it is about 14. Here this value can be converted to a different area and duration and output in litres, cubic metres, kilowatt hours (10 kWh per m³) or kilograms (840 grams per m³). Of course, the consumption depends on other factors such as insulation and outside temperature, so the calculated value is only a rough estimate.
Example: To heat 110 square meters of living space with gas for 5 years, based on the specified 16 cubic meters of gas per square meter per year, a total of 880 cubic meters is needed, which corresponds to 7,392 kilograms.
For heating with gas, often natural gas is used. This is a fossil fuel that contributes to global warming. While natural gas is somewhat better than heating oil in this regard, its use still causes massive environmental damage and should be avoided as much as possible. Even during natural gas extraction, large amounts of methane, a potent greenhouse gas, are released into the atmosphere. Furthermore, natural gas often comes from countries with dictatorial governments, which are financially supported through the purchase of this raw material. Instead of natural gas, some gas heaters can use hydrogen or artificially produced methane, although this only really makes sense if these gases are produced in a climate-neutral way. Gases for combustion, regardless of how they are produced, carry a certain risk of serious accidents due to explosions.
Gas heating systems are hardly sensible for new buildings anymore. Replacing existing gas heating systems with more modern, climate-friendly heating systems such as heat pumps can also make financial sense, especially with older systems. However, expert advice is recommended here.
