Safety, efficiency, and cleanliness are still the three keywords to choose a well-vented propane heater. In fact, this traditional instrument has not changed much in terms of technology in recent years and is still the cheapest way of heating a room in all places where natural gas does not arrive.

Buyer Guide to Choose the Best Vented Propane Heaters

Safety First

Any buying guide for a vented propane heater can only begin with the safety chapter. Unfortunately, this tool is still far from the infrequent cause of fatal accidents, linked more than to the risk of fire or explosion, to the emission of lethal carbon monoxide.

It is, therefore, useful not only to scrupulously follow the manufacturer’s instructions regarding the necessary maintenance but also to inquire about the precautions to be taken during use by the health authority, since the ASLs often issue-specific practical guides.

We also point out that today’s models are generally equipped with sensors that detect poisonous fumes and gases. The device turns off automatically, and an alarm is triggered. In our ranking of the best products, we have highlighted the presence in every case in which we found it.

Light to Move

On the market, you will find devices of variable weight, and the best brand models are equipped with wheels. Remember that just because it does not need to be connected to a chimney,

The gas stove is ideal for heating rooms in which you do not live or live all day (for example, a workshop) or where there is ‘is already a fixed heating system. It is, therefore, a good idea that it is easily movable, that is, light, and with the jet of hot air swiveling, so that it can be directed to the area you want to heat.

There are also outdoor heaters that serve to keep you warm in particular situations, for example, when you go fishing. They are obviously tiny and light, equipped with a comfortable carrying handle, and very functional for the use for which they were designed.

If you compare the prices with the others, you will find that they are quite cheap, although obviously of much more limited scope.


It doesn’t look like it, but fans and burners produce decibels. Quietness is, therefore, a criterion to consider when deciding on the purchase of a gas stove. You can easily verify this by checking the various consumer reviews when you read the specifications of the model you are interested in.

Another aspect to consider is the emission of bad odors, which unfortunately is often an indication of a malfunction of the appliance.

Finally, we conclude this guide by remembering the importance of purchasing products according to the standard, i.e., that exhibit the CE mark, and also to install a carbon monoxide detector in the environments in which you intend to use the appliance. It will be an extra scruple, but you can’t mess with gas.

How to Use a Vented Propane Heater

In the past, the vented propane heater did not enjoy great popularity compared to much more traditional systems such as the fireplace. In fact, it was considered very dangerous and was chosen as a heating tool only by those who could not use others.

Efficient Stoves

Today, of course, technological progress has led to the construction of ever safer and more efficient gas stoves, minimizing structural problems that would cause leaks and similar accidents.

Operating through gas, just like the stove, it is, however, essential to have some care in handling it and above all, you must never forget it on because, if it is in a closed environment, after consuming the oxygen necessary for combustion, it will produce carbon, a poisonous, odorless and tasteless gas.

There are several types on the market; they all have in common; however, the use of a gas cylinder for operation.

New Products

Our advice is to choose new and reliable products since stoves that already have a few years behind them may not be equipped with cutting-edge safety tools.

After getting your stove, you will need to purchase a gas cylinder. Usually, there are home delivery services that you can count on if you have no way to move around independently to obtain fuel.

Position the Cylinder

To position the cylinder in the appropriate rear compartment, you usually need to remove a panel that acts as a protection for it. For some models, just move it upwards and pull the board towards you, releasing it from the stove.

The procedure usually takes a few seconds. However, we recommend that you also take a look at the instruction manual to understand what type of closure the product you have purchased has.

Now gently place the cylinder in the internal compartment and connect the gas pipe and the fitting to the cylinder using a wrench. Alternatively, if you do not have these tools, you can request installation at the gas home delivery service.


When the time comes to turn off the stove, always remember to close the gas knob by turning it clockwise. For your own safety and that of the other inhabitants of the house, also equip yourself with a gas detector that warns with audible alarms if the limit of the carbon monoxide tolerance threshold in the air is reached.

Other small measures include not placing the stove near flammable materials such as sofas, fabrics, curtains, and the like.

Frequently Asked Questions

Who Fixes the Vented Propane Heater?

Periodic repair and maintenance of the stove must be entrusted to competent and attentive personnel. For example, not everyone knows that the pipes that connect the cylinder to the furnace must be replaced periodically because they are subject to expiration.

This information is reported on the same tube, printed in plain sight, to indicate the moment of replacement.

Usually, those who sell the same LPG cylinders that feed them also take care of the maintenance of gas stoves. Otherwise, other specialized professionals to turn to are the same ones who take care of installing boilers and gas cookers in a safe way.

Why Does the Vented Propane Heater Turn Off?

Again the answer is not one. The reasons can be different, and it is essential to take into account the different manufacturing characteristics of the different models.

Mostly the stove switches off when the gas in the cylinder has run out. But it is good to check that there are no problems with the tube, with a possible leak, or that it has expired and therefore less performing.

If, on the other hand, the stove is connected to the flue and is a new generation, it is necessary to consider the possibility that the CO2 sensor has detected an excessive presence in the house.

So the chimney is clogged. Or that a thermocouple failure has occurred. In any case, it is good to ascertain the specific causes by consulting the technician who installed it.

Why Doesn’t the Vented Propane Heater Turn On?

Continuous exposure to heat, expansion of materials, and wear and tear can lead to a displacement of the glow plug of the piezoelectric element. For this reason, the gas that comes out is unable to come into contact with the spark emitted, which should ignite the flame.

Trying to approach this element with great delicacy towards the nozzle from which the gas comes out, you should be able to start the stove.
