Choosing
a Camping Stove |
|
This page discusses the various types
of camping stoves, and is a guide to choosing the camping stove that best
meets your requirements.
Camping stoves are generally classified by the purpose for
which they are used (family camping, backpacking, or mountain climbing) or the
type of fuel they use (e.g. gas, liquid, solid). We begin with a discussion of
the different types and then move on to how one selects the type which is most
suited for a given use.

Camping
Stoves: Objective |
|
Camping stoves are generally
designed for one of the following purposes:
-
Family camping stoves: These stoves are
easy to use and designed with safety in mind, with the expectation that the
users are typically relatively inexperienced. They are the largest of the
three types, partly because they need to feed a family and partly because
weight is less of an issue than the following two types. As a minimum they
will have a large gas hob (much like one would find on a domestic gas
stove), but it is common to have more than one hob and some even have a
grill attached as well. In addition to the stove itself being relatively
large, the gas canister attached to it will be relatively large as well.
-
Backpacking stoves: These stoves are
designed with the idea that they will be carried substantial distances in a
backpack (e.g. during hiking, rambling, cycling or fishing trips).
Consequently, weight is an important issue, so they tend to be smaller then
family camping stoves and of a lighter construction. To meet this
requirement, they will generally have only one hob, which is of moderate
size. They may be gas, liquid or solid fuel; in any case the fuel container
will be smaller than with a family camping stove (partly to save weight,
partly because the intention is to provide a very basic meal rather than a
standard family meal).
-
Mountain stoves: These stoves are designed
for minimum size and weight (both of which are critical in mountain
climbing), both in terms of the stove itself and the fuel. It also
needs to operate under very cold conditions and in low atmospheric pressure.
Consequently, they are very lightweight and generally use a liquid fuel
(liquid fuels give the best performance under difficult conditions and also
gives the most heat for a given amount of weight). One can also find
mountain stoves that use gas as a fuel, but they are only suitable for
low-level mountain climbing. To save on size and weight they have only a
single, small hob (being the smallest of the three types of stoves). They
may also be more complicated to use, as ease-of-use is also sacrificed to
save weight and space.
As a rough guide:
-
If weight is not a major concern and you want the
convenience of a stove that is easy to use and will cook for multiple people,
you are probably interested in a family camping stove.
-
If size and weight
are more of a concern (e.g. you are carrying it for substantial distances in a
backpack or in a bicycle's saddle bags), then a backpacking stove is
likely more suitable.
-
Finally, if your stove must have minimum size/weight, you will need a
mountain stove.

Fuel
Types |
|
Most modern camping stoves use either gas (e.g. propane) or
liquid fuel (e.g. white gas). However, there are a range of other fuels as well.
Following are the main types:
- Gas Canister:
This consists of a metal container with burnable gas (butane or
propane), much the same as the container for a gas barbeque, except smaller.
Stoves using gas are generally easy to start and to use (like a gas
barbeque); just turn on the gas and light it. However, they are not suitable for high altitudes
(mountains) or very cold conditions. Also, when the container is empty it
may not be possible to refill it, so one must dispose of the canister and
buy a new one, which is wasteful and makes this fuel type more expensive (as
one has to pay not only for the fuel, but each time for the container). The
gas can be Propane, Butane, Isobutane, or a mixture (e.g. butane and
propane). Gas stoves tend to be less expensive than liquid fuel stoves (for
equivalent capacity, quality and features) to buy but have a higher running
cost (as the fuel is more expensive). Consequently, if you use your stove
infrequently a gas stove is probably less expensive but if you use your
stove a lot, then a liquid fuel stove is less expensive.
- Liquid Fuel:
A petroleum based liquid fuel will work in more conditions than gas (e.g. in
very cold conditions and in low atmospheric pressure conditions), so it is
almost always used for serious mountain stoves. It burns hotter than gas
(food cooks quicker) and performs better in windy conditions (see discussion
further down on wind screens). It has a better heating
capacity to weight performance than gas, so it is often preferred in
conditions where weight is important (e.g. backpacking). It also
has a lower running cost (as one simply refills the canister when empty,
rather than buying a new canister). With gas stoves the heating capacity
drops as the gas canister empties (due to a drop in pressure) but with
liquid fuel stoves the heating capacity is unaffected by the amount of fuel
left. However, stoves based on liquid fuel are
somewhat more complicated and take more effort to light. To start the stove
the fuel has to be pressurized (normally by a pump built into the stove) and
priming is needed to pre-heat the fuel and convert it to gas. A liquid fuel
stove also requires more cleaning and maintenance than a gas stove. They are
more complicated and consequently more likely to fail. Unlike a
gas stove, it is difficult to run a liquid fuel stove on very low heat (e.g.
to simmer a pot of water rather than boil it). Consequently,
it lacks the ease-of-use and simplicity of a gas stove.
- Methylated Spirits:
Methylated spirits is a safe fuel as it is less explosive and burns at a
lower temperature. However, the fact that it burns at a lower temperature
means that your stove takes longer to cook your food.
- Solid Fuel and Gels.
Stoves that use solid fuel (tablets) or gels (a thick petroleum-based
semi-liquid) are generally save, inexpensive and lightweight. However the
fuel tends to be a bit messy and it is difficult to regulate the
temperature. Also, stoves based on these fuel types are not as quick to cook
food as gas canisters and liquid fuel.
- Other fuels. There are
a range of stoves which use other fuels, including ones designed for burning
wood that one finds in the forest. Finally, there are solar stoves, which
are very green but have the drawback of being very slow and dependent on the
weather.
Of these types, most people choose a stove which uses gas
(for ease of use) or liquid fuel (for performance and cost effectiveness). There
are also some hybrid stoves, which can use both gas and liquid fuel.
Unfortunately, hybrid stoves tend to be somewhat heavier, more expensive and
more complicated than stoves that use only one type of fuel. As the vast
majority of people find that the most suitable type of stove is either a Gas
stove or a liquid fuel stove, following is a summary comparison of the two.
People new to camping generally prefer a gas stove (for ease of use) whereas
frequent campers often buy a liquid fuel stove (due to the power and compactness
of liquid fuel).

|
Weight |
Liquid fuel stoves weigh
more than gas stoves. However, taking into account the fuel container
weights, gas canisters are at least double the weight of the
corresponding amount of liquid fuel. So, for very small amounts of
cooking a gas stove plus fuel may weigh less overall, but for large
amounts of cooking a liquid fuel stove weighs less overall. |
|
Size |
Gas stoves tend to be
smaller than equivalent liquid fuel stoves. However, liquid fuel is more
compact than the equivalent sized gas canister. Consequently, for small
amounts of cooking a gas stove plus fuel may be more compact but for
large amounts of cooking a liquid fuel stove plus fuel is more compact. |
|
Ease of use |
Gas stoves are easier to
start and to use. It is also easier to regulate the temperature and
easier to run the stove on low. |
|
Maintenance |
Gas stoves require less
maintenance (e.g. cleaning), are less likely to fail and are easier to
repair |

Gas
Camping Stoves: Choosing a type of gas and gas cylinder |
|
If you choose a gas stove, there are several different
types of gas to select from. Following is a summary:
-
Propane burns cleanly and produces a hot,
steady flame. It works well in very cold temperatures and at high altitudes.
However, the gas canisters for propane have thick metal walls, making them
unsuitable for applications where weight is important (e.g. mountain or long
distance backpacking).
-
Butane and Isobutane burn well and
work at high altitudes. However, they are not very hot and do not work well
at low temperatures (under 40º F. or
4º C.) as the gas doesn't vaporize
well. However, the gas canister is lighter than for Propane.
-
Propane & Butane blends combine the
benefits of Propane (work well at cold temperatures) and Butane (relatively
light canister). The higher the percentage of Propane, the better the
performance under cold conditions.
Before purchasing a given type of gas, ensure that your gas
stove accepts that type of gas. Also check that the connection on the gas bottle
fits your stove (there are many different types of gas connections, which vary
by country, manufacturer of gas canister and even type of gas).
With some gas stoves the gas canister connects directly to
the stove whereas with others the gas canister connects via tubes or gas lines.
The former tends to be a lighter and simpler package overall. If the gas
canister connects directly to the stove, the stove may have been designed with a
specific type of canister (and maybe even a specific manufacturer of canister)
in mind; check compatibility before you buy.

Liquid
Fuel Camping Stoves: Choosing a type of fuel |
|
With liquid fuel stoves, in addition to the intended type of liquid fuel (e.g.
white gas or Coleman fuel) the stoves often will burn a variety of different
liquid fuels (e.g. diesel, kerosene, petrol, gasoline, etc.). While these
alternative fuels are generally inferior to the standard liquid fuels (and in
some cases will clog the stove), they are readily available almost anywhere.
Consequently, if travelling in undeveloped countries or remote regions where
standard camping stove fuels are unavailable, the ability to use these backup
fuels may be important to you. Here is a short summary of liquid fuels:
-
White Gas or Coleman fuel. Burns
cleanly and provides a strong heat (allowing fast cooking). It performs well
in most weather conditions. If spilled it evaporates quickly and without
leaving an odour (an important point as it is almost certain that you will
spill some at some time). Widely available in UK and North America but may
be difficult to find in many countries. Coleman fuel is a proprietary
version of white gas which has been (or so it is claimed) specifically for
Coleman stoves.
-
Alcohol. Burns cleanly and is a relatively
safe fuel. If spilled it evaporates quickly and without leaving an odour (an
important point as it is almost certain that you will spill some at some
time). However, if burns cooler than other fuels (cooking takes longer)
and less efficiently (poor heat to weight ratio). It is also relatively
expensive. With clear alcohol it can be difficult to see the flame, which
can be a safety issue.
-
Kerosene. Widely available in almost all
countries and inexpensive. However, it is a dirty fuel and can gum up fuel
lines, requiring more cleaning and maintenance of your stove. The fumes
smell and are toxic. However, somewhat safer
than gasoline (see immediately below).
-
Unleaded gasoline (UK: car petrol). Widely
available and relatively inexpensive, but burns very dirty. It also tends to
gum up fuel lines. If it spills it can ignite easily and under certain
conditions can explode. The fumes smell and are toxic. Consequently, an undesirable fuel which should only
be used if no suitable fuels are available.

General
Tips |
|
If size and weight are not major issues, try to get a stove
with at least two burners. Most meals need a minimum of two burners (e.g. one
for potatoes and one for meat; or one for pasta and one for a sauce). A single
burner stove does mean that you can have something hot, but it is relatively
limited in terms of meal choices compared to 2-hob or 3-hob stoves.
If you are cooking with large (heavy) pots, you will need a
stove with broad hob supports and wide legs in order to prevent the pot tipping
over and to support the weight of the water in the pots. If you are cooking only
with a small pot (e.g. to boil water for coffee), then a smaller and more
light-weight stove is adequate.
The product information for stoves typically specifies the
weight of the stove. However, this weight is usually that of the stove itself
and does not include the weight of the fuel or the fuel container. When
calculating the amount of weight you will be carrying, all three items need to
be included (plus any accessories, such as windscreens, pots and other
cookware).
If you are purchasing a stove which uses gas, consider
buying one with a push-button ignition as this is more convenient than matches.
However, in case the ignition fails (which it can do if it gets wet or breaks),
you should carry some matches as well.
It is preferable to have a stove with an adjustable flame,
so you can control the amount of heat (and the rate of fuel consumption).
If your stove doesn't come with a carrying case, consider
purchasing a padded case which will protect the stove knobs and hoses.
Check if your stove works with standard
fuel canisters, or if you have to use a special fuel canister (e.g. one from the
same manufacturer as the stove). It is preferable that it uses a standard fuel
canister and canister connection, so that replacements are readily available.
A camping stove generally will not work
well in windy conditions, as the wind blows the flame and the heat of the flame.
This means that you will need much more fuel and a much longer time to cook than
in non-windy conditions. To prevent this, the stove must be protected from the
wind by:
-
Build a shelter or take advantage
of existing shelter. Building a lean-to, forming a small windbreak with some
stones, or cooking behind some object (e.g. a boulder) may provide
sufficient shelter.
-
Buy a stove which comes equipped
with a windbreak. Some stoves are equipped with a windscreen. If you
frequently camp in windy areas, they are worth considering. However, while a
useful feature, it adds to the weight and size, so one has to balance
carrying the extra load against the convenience of a built-in windscreen.
-
Cooking inside the tent.
Many people advise that this should never be done, due to safety risks and
also due to the possibility of damage to the tent or contents. However, if
you decide to ignore this advice, ensure
that the stove flame and any other stove surfaces are well away from any items that can
melt or burn (such as your tent walls, roof, sleeping bags, etc.). Also,
ensure that there is some ventilation, to avoid risk of carbon monoxide
poisoning.
Aside from size and weight, it is useful to look at the efficiently rating of
stoves. How hot can they burn? How long do they take to boil a litre of
water? How long can they run (at minimum and at full) on a single fuel tank? How
long on a kilogram (or pound) of fuel?
When purchasing a stove, ask which items are most likely to break or wear
out. Also check what tools you will need to change them (will a standard Swiss
army knife do, or do you need special tools?). It is useful to carry a basic set
of spares along with any tools required to exchange parts, in case your stove
fails while you are camping.
Try using your stove at least a week before you actually go camping. It is
much better to learn how to use it and to correct any possible problems (e.g.
your gas canister has the wrong type of connection for your stove) before you
depart on your camping trip.
For safety reasons, airlines generally do not allow transport of fuel or of
stoves which have been previously used, no matter how carefully they have been
cleaned. Consequently, do not plan on travelling by air with your stove unless
it is brand new and you are buying your fuel after you land (even then, you
still have the issue of the airline not allowing you to transport your stove for
the return trip, as it is now used and consequently contains potentially
dangerous fuel fumes).
