How Do You Choose a Propane Heater?

The first and perhaps most important consideration is size. When looking to heat a space, you must know its dimensions first, to understand what capacity the propane heater will need to have. Larger rooms will need a higher BTU (British Thermal Unit) rating than smaller rooms. As a general rule of thumb, you will need around 35 BTU per square foot of space.

Secondly, consider the energy efficiency of the model you are looking at. In particular, choose the right BTU and ensure that it has a temperature control will help to ensure you have a more energy efficient option.

Consider the price of the model you are purchasing. It may come with all the bells and whistles, but is it more than you need? Are you shelling out a lot of money only to realize it is far more than you require for your given space? If this is the case, you’ll end up paying much more in operation than you originally planned.

In terms of safety features, you want to look for two main things: tip-over and overheat shut-off. Tip-over shut-off will kick in, if the heater or gas tank falls over, which can prevent a fire. The overheat shut-off will turn the heater off when it reaches a certain temperature, protecting it from becoming too hot. Having an oxygen measure is a bonus as it can prevent the production of carbon monoxide. Moreover, cool-touch exteriors are important, especially if you have children and pets.

Be aware that some propane heaters need electricity to function as their ignition mechanism can be a continuous electrical ignition. In this sense, it prevents the heater from going out but will need to be plugged in.

How Does a Propane Heater Work?

A propane heater works by burning propane. An ignitor, usually a piezoelectric igniter, sparks the fuel. These are often made of quartz. The fuel passes over an element, often porcelain, which distributes the heat by spreading the flame out into a pattern.

Most often a propane heater will have a pilot light which will be used to relight the fuel if it goes out, instead of having to light it from scratch each time. Most heaters are adjustable in temperature, with many having thermostats for automatic temperature balancing.

Propane Heaters vs. Electric Heaters

Firstly, propane heaters are very reliable. Electrical heaters need a strong power source such as the main electricity grid, which is not always an option for everyone. If you live in rural areas or are traveling in a motorhome, the likelihood is that an electrical heater puts far too much strain on the electricity supply.

Propane is quite energy efficient as it contains a high percentage of energy per pound of fuel. That is why it is relatively cheap to run; far less expensive than electricity. Although electric heaters are less expensive in upfront costs, propane is a more economical fuel in the long run. Equally, propane heaters tend to heat air to a warmer temperature than electricity.

Propane heaters are more environmentally-friendly than electric heaters. Long known as the green energy, propane uses less fuel, and the heater generally lasts longer due to higher durability.

One problem with propane is safety. Propane canisters can prove to be an issue if knocked or pierced. Equally, unvented propane heaters are dangerous inside. So make sure to use a vented propane heater when inside if possible. Carbon monoxide poisoning can be a real risk if propane is not burnt efficiently and with enough oxygen. Ensuring that your propane heater has the mechanisms to detect this, will help to prevent it from occurring.


When choosing your propane heater, it is important to ensure that you have the right heater for your circumstance. If you are looking for something to go inside your home, never choose an external heater as they do not have the safety mechanisms and vents to deal with carbon monoxide.

Equally, you’ll find that indoor heaters are designed to cope with interior spaces better. Always bear in mind your own needs, and find a heater that suits you.

People Also Ask

Propane heaters are characterized by their use of a clean-burning source. Now that you have gone through the top models you can go for, it’s time to clear up any confusion so that you can be confident in your purchase.

Are Propane Heaters Safe for Indoors?

There are specifically designed propane heaters for the indoors. These are not only safe but also come with additional safety features, including low oxygen-level detectors. Despite that, it’s essential to take necessary precautions while using these indoors.  

How Long Will a Propane Heater Last?

A propane heater with a standard 20-pound tank can last for 10 hours. However, the number of hours can vary depending on the BTU of your unit.

Do You Need Ventilation for a Propane Heater?

Since propane heaters work by using up the oxygen in the air, ventilation is necessary if you want to use a propane heater. If not, then the unit will eat up all the oxygen, putting you at risk.

Do Indoor Propane Heaters Need to be Vented?

Yes, indoor propane heaters must be vented. This is because propane heaters can serve to be carbon monoxide hazards if they are used without sufficient ventilation in place.

How Long Will 100 Gallons of Propane Last?

One gallon of propane has roughly 91,500 BTU’s of heat. So, when you do the math, 100 gallons would have roughly 9,150,000 BTU’s. Now, when it comes to how long so much propane will last, it all depends on the BTUs that your unit requires. For instance, if you have a large heater with more BTUs, then 100 gallons of propane will be used up relatively quickly.

Can You Get Carbon Monoxide Poisoning From a Propane Heater?

As they burn, propane heaters release carbon monoxide, which means such units are both fire and health hazards. They can also lead to CO poisoning in just minutes, leading to death in a very short time.

Is it Safe to Use Propane Heater in a Tent?

No, it’s not at all safe to use a propane heater inside a tent, because of several reasons. Firstly, a tent is closed and can easily catch fire. Secondly, it produces an excessive amount of CO, which is dangerous for your health.
