What to look for when buying a propane wall heater

The right propane wall heater will be a comforting asset in any room but they are not all the same. Here are some important considerations to ponder to ensure that you get the very best one for your needs. 

Room size and heating capacity

Some propane heaters produce more heat than others and some are more effective at dispersing it. You have to match the power of the heater to the size of the room you wish to heat. The way heat is measured on propane wall heaters is in BTUs or  British Thermal Units. Larger rooms will require a heater with a higher BTU rating. 

You can use this handy BTU calculator to work out the power you need according to the space you need to keep warm and cozy. 

Do not guess or gamble on this. It will be very disappointing to buy and install a propane wall heater that does not warm the room to the temperature you require. It will be money wasted. Many of them specify the average heating area so be sure to check.  

Design and size

The beauty of a wall propane heater is that they are slim and compact. They take up less space than most cabinet or portable heaters. They should also look good in the space they are to be used. Look at the style and colors of the room and give some thought to what will look good in the space. 

There are many different designs. Some look like a real fireplace which is great in certain environments. Some are sleek and modern while others have a more traditional look. Some are also available in a range of colors to suit your style and taste. 

Also, consider the space available, measure if necessary. Look at the dimensions of the unit to ensure it will fit in snugly and not be in the way. 


Modern propane wall heaters are safe provided they are set up and used correctly. One concern is pets and children. If you are worried about this look for a heater with a safety guard for added protection. Even better is a heater with a cool-touch exterior. This is the best option for homes with small children and pets.  

An oxygen depletion sensor (ODS) will shut the system down if the indoor oxygen levels are low. This is important on any propane heater that is used indoors. Tip-over protection is generally not an issue as these heaters are normally mounted but it is still good to have. 

Overheat protection is another good safety feature to have. 

CSA certification, although not essential, is a good sign that the heater meets all the necessary safety standards. 


Some models give the option of legs for a freestanding “wall” heater. This might be appealing in certain environments. Of these models, some come with the legs while others offer them as an additional purchase. 


There are two main types of ignition, manual and automatic. A manual ignition requires that you actively press the starter button to get the unit going. An automating ignition is much more convenient as the heater will ignite as soon as the heater is turned on. 

Durability and reliability

When investing in a propane wall heater and going to the trouble of positioning it and mounting it, you want to be sure that it will deliver many years of warmth. Avoid the cheap and nasty models as you will simply need to replace them fairly often. 

It is difficult to tell the durability and reliability before making a purchase but there a few things you can look at. Firstly, the reputation of the company. A company that has been going for many years and is popular is always a good sign. That is not to say one should always avoid new companies as many are very good but a company with a good reputation is a sign that they make quality products. 

A warranty is always good and will give you peace of mind. Also, look at the quality of the materials that have been used. 


There are some great propane wall heaters that are affordable and can be purchased even if you are on a tight budget. If you are looking for one with more power, extra features, a special design, or other benefits, expect to pay a bit more. 

You might need more than one heater in the house so consider your budget before making your decision.

Noise output

Most propane wall heaters operate quietly but there are some that have a fan or other features that make them a bit louder. As they are used in the home or office you want one that makes little to no noise.  


As we researched the various leading propane heaters several questions popped up regularly.  You might have some of the same questions or concerns so take a look.

What is the difference between a vented and a ventless propane wall heater?

This is something that puzzles many people, especially if they have not shopped for similar products before. It is important to understand the two options. Fortunately, the answer is quite easy.

A vented propane heater, as the name suggests, has a vent. This takes the gas produced by the heater and expels it outside the house or office. Many believe this to be healthier as there are no gasses in the building. 

The downside to this system is that the process reduces the heat and makes them less efficient. They are therefore more expensive to run. 

The installation is also a lot more time-consuming and generally has to be done by a professional. This will add to the cost of the unit. It also means that you cannot easily relocate the heater if you wish to as it will require that the vent is moved. 

Ventless heaters are much easier to install and can normally be done by anyone with basic DIY skills and minimal tools. This will be quick and easy and save you the cost of getting a professional to install the unit. It can also be moved fairly easily if your needs change. 

A ventless system is more efficient and burns better so you will save on running costs in the long run. This efficiency also means that they burn most of the gasses so there is minimal risk of gasses building up. 

The best propane wall heaters have excellent safety features and are not harmful or dangerous. 

How do I select the correct location to mount a propane wall heater?

This is another critical consideration. For maximum effectiveness, efficiency, and safety, you need to select the ideal spot. 

If you are installing a vented heater, the question is even more complex as you have to think about where the vent pipe will run. They need to be mounted against an external wall allowing the vent pipe to run to the exterior of the building. 

The other consideration, which applies to both vented and ventless models, is the positioning of the propane tanks. In most cases, these will be located outside. The closer you can position the heater to the tanks the better. 

Also, bear in mind that hot air rises so it is best to mount the heater low rather than higher up. 

Final thoughts

So there you have it, the 5 best propane wall heaters. There is something to cater to all tastes and styles, all heating requirements, and all budgets. Take some time to think about the important considerations in the buyer’s guide, evaluate the space you wish to heat and you can confidently select the perfect heater for your needs.
