How much gas does a gas fireplace consume?

How much gas does a gas fireplace consume? A frequently asked question with no single answer. There is no standard gas consumption for every gas fireplace. The consumption of a gas fire obviously depends on the capacity of the fire, the room to be heated, but also on your heating behaviour. Perhaps you turn your gas fireplace to a low setting every day, while your neighbour's is on full blast every day. Various factors therefore influence the amount of gas a gas fireplace consumes. Of course, we can assume an average.

We will answer the following questions for you:

What is the average gas consumption of a gas fire?

The average consumption of a gas fireplace depends on several factors. To calculate the average gas consumption of a gas fireplace, we must assume an average power. The somewhat smaller fireplaces have a power of about 4kW, while the larger gas fireplaces sometimes have a power of up to 12kW. For a living room of an average size (92m3), a fire with an output of about 7kW is sufficient. A gas fire with this power at full setting consumes about 1 cubic meter of gas per hour.

Gas consumption therefore strongly depends on how many hours you use the fireplace and how you use it. Heating behavior is therefore an important factor in determining the gas consumption of a gas fireplace. And even the insulation of your home affects consumption. To get an average understanding of the gas consumption of a gas fireplace, we use the following calculation.

Cost per hour = (consumption per kWh * 110%) * (0.15m3 * current gas price per m3)
Cost per evening = cost per hour * 4

How do you determine the power of a gas fireplace?

Now you know that the capacity of a gas fireplace determines a large part of the gas consumption. But how do you actually determine what capacity you need to heat your living room? It is important to choose a gas fireplace that meets your heating needs. You can do this in two simple steps.

1. Determine the room's volume
Start by determining the volume (m3) of your living room, or other room you want to heat, of course. The volume is calculated by multiplying the length, width and height. For example: 6*4*3= 72 m3.

2. Determining the degree of insulation
The degree of insulation also plays a big role in determining the capacity of your gas fireplace. Find out whether your home is well insulated. By 'well' insulated homes, we mean homes that have double glazing as well as roof, floor and wall insulation. If your house lacks one of these components, it is moderately well insulated. If none of these components are present, we call your house poorly insulated. In the graph below, you can see on the left what capacity you need, for what level of insulation and for what volume of space to be heated.

A - Well-insulated house
B - Moderately insulated house
C - Badly insulated house

What is the output of a gas fireplace?

Unlike a gas stove, for example, a gas fireplace is not usually the main source of heat in a home. Because gas fireplaces used to serve mainly for atmosphere, the efficiency was a lot lower compared to a gas stove. However, the gas fireplace as a modern mood creator nowadays certainly also provides cosy warmth. The efficiency or yield of gas fires is therefore very high nowadays. Sometimes up to 85%!

An output or efficiency of 85% means that the gas fireplace radiates 85% of the generated heat into the room to be heated. The remaining output dissipates through the flue and is called heat loss. The lower this heat loss, the higher the yield of your gas fireplace.

How does gas consumption affect the energy label?

Modern gas firesplace, like almost all other appliances, have an energy label. With this energy label, you can see at a glance the capacity, efficiency and consumption of the intended gas fireplace. The more efficient the gas fireplace and the lower its gas consumption, the higher the score on the energy label. If gas consumption is an important factor in your choice of gas fire, we recommend that you take a closer look at the energy label of your fire. That way, you can make a conscious choice for your new fire.
