Vented vs Ventless Propane Wall Heaters

One of the first things to consider when choosing a wall-mounted propane heater is whether you want a heater that vents to the outside of your house or one that operates without a vent. Most commonly you will find that propane wall heaters tend to be vented.

It means that they vent the gases from the heater to the outside of the house, usually through a vent pipe. This vent pipe is attached both to the heater and to your home and goes through the wall on which the heater is mounted. It prevents any noxious gases from entering your home, therefore being healthier.

However, the problem with vented propane heaters is that they lose heat through the ventilation, making them less efficient than those without vents. The loss of efficiency means you will need to burn more fuel which is less eco-friendly and costs more.

Moreover, the installation requires a lot more effort, especially if you don’t already have a hole for the ventilation pipe to be fed through. You will need a professional to install the heater, which also raises the costs.

Ventless heaters are far easier to install and are more efficient. However, the lack of vent to the outside means that these types of propane wall heaters vent the gases into the room in which the heater is installed. However, the higher burn efficiency reduces considerably the chances of harmful gases entering the household.

Things to Consider Before Buying a Propane Wall Heater

First and foremost, you need a heater with the capacity to heat the space you choose. With propane wall heaters, you need to look at the BTUs (British Thermal Units) to determine if the heater has enough power to warm a room properly. As a rule of thumb, you need around 40 BTUs per square foot.

Consider how the heater ignites. Some heaters come with automatic ignition as soon as the heater is turned on, which is a very effective tool and extremely easy-to-use. Other models will come with manual ways of igniting. While it may seem less convenient, ignitions tend to wear out over time, and therefore those that can’t be ignited manually become useless.

You need to think about where you will be putting your heater as it will lead to certain choices you make. For example, if you already have a ventilation pipe in your living room, vented options are the most sensible.

However, if you don’t, and if there is no external wall, you will need to consider a ventless option. Moreover, if you are choosing a heater for the exterior of your home, you need to look for outdoor propane heaters. In the same breath, outdoor heaters should never be used inside.

Safety features are also important, especially if you have small children or animals. Overheat protection helps to cut off the heater if it starts to get too hot, preventing a fire. Some propane heaters will have cool-to-touch exteriors that prevent burns if touched.

Moreover, look for one with a safety guard to decrease the chance of getting burned. Think about your budget. While there are cheaper options for propane heaters, they usually sacrifice safety features and tend to be less efficient. Regarding this, consider the cost and look for the best option in your price category, always remembering the additional cost of propane.

Choosing the Right Mounting Location for a Propane Wall Heater

Selecting the right location for your propane wall heater is important so that it works effectively and safely.

The first thing to think about is whether your propane wall heater is vented or ventless. Vented heaters are more limited about where they can be placed as there is the need to access an external wall so that the vent pipe can be run outside. With both options, however, the propane tank needs to be set outside.

With this in mind, you will want to mount your heater as close to the tank as possible, to make it easier to run the piping. That is why, most people will choose to have ventless wall heaters placed on an external wall as well, simply for ease of the process.

Generally, it is better to place your heater low down as heat rises. It will ensure a more consistent temperature as warmth is able to spread more evenly throughout the room.

Safety Features to Consider When Buying Propane Wall Heaters

Propane heaters can be extremely dangerous as gas is highly flammable. It is important to consider the safety features, especially if you have children and pets.

On a basic level, you need to look at propane wall heaters that have a safety guard on the front to reduce the chance of burning yourself. Looking for a heater with a cool-to-touch guard increases the safety level. You can also source propane wall heaters that have cool-to-touch casing as well, which means that the whole heater stays cool despite radiating heat outward.

Secondly, look for a unit with overheat protection. When they get too hot, they run the risk of setting on fire. Overheat protection shuts off the heater if it reaches a certain temperature or if the components get too hot. Efficient propane burners produce carbon dioxide. However, if the oxygen levels drop or the combustion level lowers, the propane can produce carbon monoxide.

It is a toxic gas that is colorless and odorless, posing a huge risk to your health. Some wall propane heaters include a low-oxygen shut-off. It turns the heater off if the oxygen levels get too low or if combustion isn’t happening to the fullest.

Try to look out for safety certifications to verify the safety levels of the heater. Propane wall heaters that are certified by CSA meet all the safety standards necessary for a propane heater to be at a house.
