## How long does a gas cartridge burn?

In preparation for a longer hike, perhaps with a tent, the crucial question arises: How long does a gas cartridge burn? On the relevant question-answer portals such as gutefrage.net or YahooAnswers! Unfortunately, there is little that is helpful in this regard. For example, it says “3 to 4 hours”. You can't do anything with such an answer, because there is usually no information about the size of the cartridge.

The stove comparison on outdoorseiten.net is better. But even this really practical list does not answer the question asked at the beginning. Because I wanted to know exactly, I quickly put the test to the test and determined the burning time or the service life of a gas cartridge myself with the help of a test run.

If you haven't had enough time to travel through the Internet, the answer will now follow. If you are interested in the experimental setup and the overall conditions, just read on.

#### How long does a gas cartridge burn? The answer is:

 A standard screw cartridge with 230 grams of gas holds around 19 to 20 firing processes of 3:48 minutes each. Converted to approx. 71 to 76 minutes burn time. The basis for this is to heat 1 liter of water to boiling point. Such a cartridge is sufficient for three similar burning processes per day 6 to 7 days. In any case, this is the result of the test run described below.

This is just ONE answer to the question of how long you can cook with a gas cartridge because:

Changed conditions have a direct effect on the burning time and consumption.

• The stronger the wind, the longer the burning time per burning process and the higher the consumption.
• The colder the water (e.g. from a stream instead of tap water), the longer the burning time per burning process and the higher the consumption.
• When the amount of water is reduced from 1 liter to 0.5 liter, the burning time also decreases, but not by exactly the same factor. Example: If only 0.5 liters of water (sufficient for most dry food meals) are heated, the MicronStove gas cooker burns 6 grams of gas. In this case, the burning process takes about 2:15 minutes.

#### Thus, in summary, it can also be said

 If you heat 0.5 liters of water 3 times a day, you can get by with a 230-gram gas cartridge for around 12 to 14 days.
As I said: the on-site conditions may lead to a change in the burning time and a change in consumption. All values ​​shown here are only approximate values!

### The test process in detail

After I gave an initial answer about how long you can cook with a gas cartridge, now something about the methodology of the test run.

To name the lifespan of a gas cartridge, I brought 1 liter of water to the boil. Before the burning process, I determined the weight of the cartridge in order to compare it with the weight that could be determined after the burning process. With the help of the consumption per burning process, which is defined in grams, the service life of a gas cartridge can be wonderfully determined, regardless of its size or volume.

A total of three firing processes were carried out, two with a gas stove each and one with the Trangia spirit stove, the classic among stoves. The experimental set-up and conditions were identical in each case.

• 1 liter of water (tap water)
• Outside temperature 22 degrees (° C)
• little wind
• Valve fully open
• The lid remains on the pot until it simmered
• The balance used determines an accuracy of 0.01 units; all gram values ​​are rounded to even numbers

### Comparison of consumption

(Bring 1 liter of water to the boil)

producttimeconsumption
Test 1: MicronStove Ti 2.5 (Primus) gas cooker3:48 min.12 grams
Test 2: Spirit stove (Trangia)10:14 min.26 grams
Test 2: Markill gas cooker (Vaude)4:47 min.14 grams

The comparison shows that the small MicronStove Ti 2.5 gas cooker from Primus is the most effective solution in this test environment for heating 1 liter of water. Effective both in terms of burning time and weight.
