What is the average gas consumption of a gas fire?
The average consumption of a gas fire depends on several factors. To calculate the average gas consumption of a gas fire, we need to take an average power rating. The somewhat smaller fires have a capacity of around 4kW, while the larger gas fires sometimes have a capacity of up to 12kW. For an average-sized living room (92m3), a fire with an output of around 7kW is sufficient. A gas fire with this power at full output consumes about 1 cubic metre of gas per hour.
Gas consumption therefore strongly depends on how many hours you use the fire and how you use it. Heating behaviour is therefore an important factor in determining the gas consumption of a gas fire. And even the insulation of your home affects consumption. To still get an average insight into the gas consumption of a gas fire, we use the following calculation.
How to calculate the gas consumption of a gas fire
You can now calculate for yourself within 1 minute how much a gas fire uses with the gas consumption calculator
We take the following starting points:
- Gas fire: DRU Convexo Eco Wave
- Gas price: € 1.45 per m3 (Based on energy ceiling October 2022)
- 1 kW of heat requires 0.15 m3 of gas.
- Average efficiency of 90%
With this, you arrive at the following sum:
Cost per hour = (consumption per kWh * 110%) * (0.15m3 * current gas price per m3)
Cost per evening = cost per hour * 4
|Consumption per hour
|Cost per hour
|Cost per evening
| 2.1 kW
| € 0,50
| € 2,00
|Eco Wave (recommended)
| 3.4 kW
| € 0,81
| € 3,25
| 4.7 kW
| € 1,12
| € 4,49
The setting naturally affects the flame pattern. At full setting, your consumption is highest but also equals continuous high, full flames and a lot of heat. Because of the good insulation of homes and the local function of a fire, this full setting is often quickly too hot. The Eco Wave function is therefore a perfect alternative to reduce your consumption but continue to enjoy beautiful flames. Want to save completely? In low mode, you consume the least but your flame effect is also limited.
Difference with an electric fire
So stoking your gas fire does not necessarily have to be very expensive. Especially when you compare it with, say, an electric fire. For electricity, you currently pay 0.40 per kW hour. This times a consumption of 2.1 kW, you already come to € 0.84 cents per hour! Note that most electric fires only heat up to max 2 kW per hour, so a gas fire will always be more effective as an efficient local heater because of its capacity.
What is the gas consumption of a propane fire?
Just about all DRU gas fires can also be lit on (BIO) propane
from bottles. The most common propane bottle contains 10.5 kg of gas. Based on the same assumptions as in the above example, the consumption of a propane fire is around 300 cc to 500 cc per hour. Again, you save around 30% to 50% on consumption in EcoWave mode.
