What to Consider When Choosing the Best Vented Propane Heater

There are various things you need to look at when selecting the best vented propane heater. These include:


As you go shopping for a vented propane heater, its capacity or the British Thermal Unit (BTU) is one crucial factor you should consider. This measures the unit’s power.

It helps the user to determine the ability of the heater to provide enough heat for the room. The standard rule is that the heater you pick should be able to deliver 40 BTUs to heat a single square foot.

Method of Ignition

Some of the vented propane heaters come with automatic ignition, while others are manually ignited. The automatic option is easy to use for everyone.

However, it does not mean they are the best since the ignition for this option does not last long. The heaters that are ignited manually last long and are a good option if you want to save money.

Model and Size

The market offers vented propane heaters in different sizes and weights. All you need to look for is the pros and cons of each and your personal needs to pick the best one. Usually, a vented propane heater is suitable for small spaces because then it will provide enough heat.

Also, in small areas like bathrooms or bedrooms, vented propane heaters will not take much space. Moreover, they allow the user to move quickly and freely in the shower and tub area.

Safety Features

Although these products can come with many benefits, they can be dangerous as well, especially when they are in a household with kids and pets. This is why it is recommended that one chooses a heater with a safety guard in front to reduce the risks of burning oneself or other family members.

Furthermore, look for a device with a guard that is cool when touched or a casing that is cool to ensure and improve safety around your home.

A good propane heater is supposed to produce carbon dioxide gas and not carbon monoxide. However, in cases where the oxygen or combustion levels come down, the heater can start producing a toxic, colorless, and odorless carbon monoxide gas, which is dangerous.

The good news for you is that some heaters turn off automatically whenever the oxygen levels fall. Therefore, it is vital to check for the heater’s safety certification to know the safety levels of the heater.

If the vented propane heater is certified by the CSA meets the needed safety standards. Safety is an essential factor, especially if you have children and pets in your home.

The overheat safety feature ensures that the heater automatically disconnects whenever the heater gets too hot. This helps prevent the breaking of a fire. Other vented propane heaters have an exterior that is cool to touch to prevent burns.


This is important because nobody would want to overspend on something, especially when they do not have that kind of money. So go for a heater that is within your budget. But be cautious of cheap options because most of them do not include safety features thus can be inefficient.

Frequently Asked Questions

How Much Ventilation Do You Need for a Propane Heater?

Ventilation is essential if you use a propane heater because it reduces the risk of poisoning from carbon monoxide. Usually, the amount of ventilation you will need will depend on the type of room you are using.

The product should come with instructions on how much ventilation you will need if you are using the model you got.

Do Indoor Propane Heaters Need to be Vented?

Yes. Indoor propane heaters need to be vented for a few reasons. One, any overheating in your home or building could cause combustible damage.

Two, if the product’s carbon monoxide (CO) output is not properly vented out of the home, a build-up will occur. This means that CO itself is a poisonous gas that can be lethal at higher concentrations over time.

Hence, it is important that indoor propane heaters are properly vented for safety reasons.

Can You Get Carbon Monoxide Poisoning From a Propane Heater?

A good propane heater will produce what is known as ideal burn, which means that only carbon dioxide is released. Therefore, this will not present any dangers from carbon monoxide poisoning.

However, if a propane heater does not automatically shut off whenever the oxygen level is low, or combustion is low, the heater will start producing carbon monoxide, which poses a threat to the users.

Can I Run a Propane Heater in a Closed Garage?

No, you can never run a propane heater in a closed garage. A closed garage is not recommended for use because there is usually carbon monoxide produced by incomplete combustion of gases.

This toxic gas could be life-threatening if left unattended and can do long-term health problems such as dizziness, nausea and headaches.

Can I Run a Propane Heater in My House?

Yes, you can run a propane heater in your house. The vented propane heaters are ideal for a house because they can direct any dangerous gases outside, keeping your family safe.

As you think of running a propane heater in a house, ensure that you pick the one with safety features to help you keep your kids and pets safe.

You can also install carbon monoxide detectors in your home to be alerted whenever this gas is released and always ensure that the propane heater is attended to or turned off if you are leaving the house.

Can You Leave a Propane Heater on All Night?

If you have ever thought about running your propane heater overnight, you may be wondering if it is safe to leave it on.

While leaving your heater on for days at a time is not advisable, propane heaters can be left on for some hours without harming the environment or your health.

Are Fumes From Propane Heaters Dangerous?

The fume produced by the propane heater is carbon monoxide which is a dangerous gas. This occurs when there is incomplete combustion of gases or low oxygen levels and generally in poor quality heaters. However, if you have good equipment, you will never experience such dangers.

Do Indoor Propane Heaters Smell?

Propane gas does not produce a bad smell, but any heater, when it is first fired up, produces a smell but not a bad one. However, some people complain of a strong odor when using this heater.

This is because of the gas leak and the chemical present in it called ethyl mercaptan, responsible for detecting leaks. It smells like rotten eggs.

How Long Can You Run a Propane Heater in a Garage?

The amount of time you should run a propane heater in your garage depends on the size and the number of BTUs available in the heater.

For instance, a pound generates approximately 21548 BTUs. This means that if you are using a 20-pound propane tank to heat your garage, you can run it for more than 10 hours.

Can Propane Heaters Explode?

Heaters that use propane as fuel are among the best heaters to use. This is because propane tanks hardly explode, and under normal circumstances, a vented propane heater uses the safety valve to vent any excess pressure that could cause an explosion, thus ensuring safety.

The heaters do not explode, but tanks can. This does not happen frequently, though.
