Guide to tent heaters: What is the safest to use?


The appeal of camping is alluring once it catches on, with every camper desiring to maximise their camping season. The cooler months of early spring or late autumn do not dampen this desire. However, the need to remain warm remains paramount, presenting a dilemma for those not keen on braving the chills of these seasons. This makes the role of heaters in extending the camping season crucial.

Using a portable heater is an easy way to extend your camping season. However, introducing heating is not as simple as it is vital to consider how safe each type of heater is.

There are three primary methods to keep a tent warm: electric heaters, wood-burning stoves, and gas tent heaters. Electric heaters present the safest option. Conversely, gas heaters pose potential dangers due to risks of carbon monoxide fumes and fire hazards. Wood-burning stoves, while an option, demand proper fitting and adequate ventilation. Each of these heaters has its own set of pros and cons, specific product examples, and safety precautions which will be further discussed.

How to keep safe when using tent heaters

It does not matter what time of year you use a tent heater; the main priority is safety. Especially if you are camping with children, children often forget the dangers whilst having fun; things can be bumped and knocked over easily, especially in a small tent.

All tent heaters should never be left unattended, placed off the ground and away from the tent walls. Electrical heaters are the safest compared to gas heaters and wood burners.

Why are electrical heaters better for tents?

Electrical heaters are suitable for tents as they do not have open flames or fumes, and they are cheaper than wood-burning stoves or gas butane heaters. Heaters must be maintained correctly.

The only drawback is that you require EHU and the wattage needs to be considered to avoid tripping the electrical supply on-site. If you are unsure of the wattage you can use on a campsite, you need to convert watts into Amps, but the Amps rating needs to include all of your electrical devices.

Even in the absence of standard on-site electricity, warming your tent is still possible through electrical heating. Using a generator can greatly elevate your camping comforts, even in situations lacking EHU (Electric Hook Up). Dive deeper into understanding generators with our article where the nuances and differences amongst the 5 various types of generators are clearly explained. To properly use a generator on a campsite, the requirements are simple – pure energy output and a noise level below 60 dBS.

The average campsite is 16 Amps. We have a chart listing basic electrical equipment, including watts, volts, and amps, which will help you determine what to buy. We have also provided the formula to convert any electrical equipment in the future.

The KW rating on a heater will determine how much heat is transmitted. The higher KW, the greater the heat output. Ideally, heaters should have a couple of KW settings, allowing you to control the heat transmitted. Either a low setting for gentle heating in the background or a burst of high heat for quickness.

Compared to other heaters, electrical fan heaters are less costly. Two recommended fan heaters would be the Warmlite WL44002, boasting two heat settings and featuring a safety cut-out switch triggering an automatic shut-off when the pre-set temperature is reached. Additionally, it offers a fan mode, proving useful during warmer camping seasons. With a modest price tag of under £20 on Amazon, it provides an economical yet dependable heating solution.

The other heater I have is the Kamper Diddy Portable heater sold at Winfield’s and Amazon. This heater is very popular and is often out of stock. The Kampa has a cut-off switch in the event of being knocked over and a thermal heat-protected case. For this reason, I use Kampa during the colder season of camping.

Are wood-burning stoves safe to use in a tent?

Wood-burning stove – Canvas and Polycotton tent heater

Indoor fires pose a considerable risk, considering that most tents are inflammable. However, using wood-burning stoves inside a tent can be a safe alternative, on the condition that they are installed correctly and treated with respect. Canvas or polycotton tents should be your go-to material as nylon or polyester tents risk melting from the heat. Tents that pair well with wood-burning stoves include bell tents, teepee tents, and various shelters.

The following equipment is needed for safe insulation and usage:

  • Flue/vent – Needs to be 6″ above the peak of a tent
  • Spark arrester – Device fitted to the top to prevent embers from leaving the flue, causing fires.
  • Heatshield – Placed on the tent wall behind the stove
  • Aluminium fixing for flue – A section of the tent is cut away for the flue and replaced with a secure aluminium ring
  • Fire-resistant base – Slab or fire-retardant base for the stove to stand on. It must be a flat, solid-level base
  • Space – Must have a clear area around the stove
  • Fire Extinguisher – For emergencies in case any embers escape
  • Heat resist gloves – Use to open/close the stove
  • Safety guard – If children are present, placing a safety guard around the stove will help avoid any burns or other serious injuries.

Before using any wood-burning stove on a camping trip, it must be burnt off first to avoid any fumes during the first usage. However, you must first understand how your wood burner works before installing it for a camping trip. Keep testing until you are fully confident.

Gas tent heaters: Why I will not use them in a tent

Portable gas heater safety controls: Safety features are essential when using portable gas heaters. Examples of these include oxygen depletion sensors, which turn off the unit if oxygen levels drop too low, and tip-over safety switches, which shut off the heater if it is knocked over to prevent a fire.

Gas heaters are dangerous and should not be used inside tents. I do not recommend using them as a heat source inside a tent because of fumes and fire hazards. Especially if you have young children. A tent needs good ventilation, which defeats the reason for using a heater in the first place.

Gas heaters should never be left burning when nobody is present, and you should always have carbon monoxide inside the tent.

The controls are the same, but the only difference is the safety ring on the side of the heater. It needs to be pulled out gently before igniting. It is a good safety switch and stops children from trying to light themselves.

If you are camping without electricity and do not want to use a gas-burning heater, there are other ways you can keep warm. Have you considered heating rocks around the outside of your firepit? They are a great way to heat your sleeping bag. Check out our 21 tips on how to keep warm when camping in cold weather.

Key takeaway

  • Safety first
  • Electrical heating is the safest
  • Fan heaters are the best way to heat a tent quickly and easily
  • Never leave a heater running on its own
  • You don’t need to spend a fortune to keep warm
