Propane wall heaters are a great solution for winter, but it’s not an easy job to find the right one for your needs.

The truth is that all propane wall heaters aren’t made the same – some are made from lower quality materials, have less power, and are far less efficient than you thought they were.

However, there are still some awesome propane wall heaters that you won’t regret buying.

Before you make the right choice, you have to learn what to look for in a propane wall heater.

Important Factors To Consider When Buying Propane Wall Heaters

  • BTU – The power of propane wall heaters is measured in BTUs. The more BTU your heater has, it’s more powerful and it can cover a larger area.
  • Thermostat – This allows you to control the temperature in the room and set it to the exact desired degree. This is a great feature to have, and it’s mostly available on modern units.
  • Easy to operate – The last thing you want is a propane heater that’s hard to operate. Always look for a one-button operation, so you just need to press the button for it to start working.
  • Tip-over safety – Propane heaters are usually very easy to knock down, especially if you have smaller kids or pets. The tip-over sensor immediately cuts off all fuel if knocked down.
  • Oxygen sensor – Having an oxygen sensor can detect dangerous carbon monoxide exposure and most powerful units have this feature.

This is the best propane wall heater you can find on the market.

What’s amazing about Rinnai’s heater is that it includes multiple smart features such as a programmable thermostat display that lets you set the desired temperature of the room.

It’s important to mention that it has self-diagnostics, so you’ll be notified when maintenance is needed.

It’s extremely safe and it even has a flame failure and overheat switch which eliminates any risk of fire. Also, it has oxygen sensors, so the alarm will turn on if the sensors are triggered.

They even have the same model that runs on natural gas instead of propane.

If I had to use one word to describe this heater it would be efficiency.

It’s very efficient and it can heat up to 750 square feet – don’t let the size fool you.

It has a built-in thermostat, so you can always control the desired temperature.

What’s awesome about this device is that you can easily move it from one room to another, and you can also attach it to the wall.

Blue flames create an even cozier feeling and it looks like you got an electric fireplace in your home.

One thing to note, it’s forbidden in Canada.

Of all the propane wall heaters I’ve tested – this one has the most advanced smart features.

If you’re a tech-type guy, you’ll absolutely love this propane wall heater.

It has all the safety features such as oxygen sensors and it has a programmable thermostat – you can set it to always heat your desired room’s temperature.

It has only 10,000 BTUs, so I wouldn’t recommend it for a larger home.

You can install it in offices, homes, apartments – and basically any other interior.

4. Powerful: Mr. Heater Blue Flame

Our Pick
Mr. Heater 30,000 BTU Propane Blue Flame Vent-Free Heater
$299.99

Although this heater is smaller than average units, it’s one of the most powerful propane wall heaters.

It has 30,000 BTU and it’s suitable for larger rooms.

What you’ll love about it is that it can operate without electricity during power outages.

Running on the highest heat settings, a full tank (20lb) will last 2-3 days without any issue.

Mr.Heater produces safe and clean burning heat.

5. Advanced: Dyna-Glo IR18PMDG

This model is available with 2 options: one that runs on propane and another that runs on natural gas.

It can produce up to 18,000 BTUs while heating rooms up to 700 sq. ft.

Infrared technology is radiating heat to warm objects first instead of releasing it into the air – this helps it be much more efficient and faster.

What I advise you to buy separately is a fan that will improve the amount of square footage that heat reaches (without producing any extra noise).

You can add base legs to keep it on the floor or install it on the wall.

6. Budget-friendly: Mr. Heater Vent-Free

This Mr.Heater model is made with a bit cheaper material, so if you’re low on budget – you should definitely get this model.

It has some of the smart features of more expensive models – such as a low oxygen shut-off system.

What’s impressive (considering the price) is that the run time is 43 hours. Some expensive models don’t have such great operation time.

It’s important to mention this is a radiant propane heat burner.

7. Premium: Martin Direct Vent

This Martin model is the most advanced propane wall heater on the market.

You can basically choose from tons of different options – from material type to the power of the heater.

My advice is to buy the 20,000 BTU model as it has the most efficient operation.

What you’ll fall in love with is an exclusive glass ceramic window that lets you watch the flame and give you a more cozy feeling when you’re snuggled on your couch.

It’s made from die-cast aluminum, so you won’t have to worry about performance or durability.

Advantages of Propane Wall Heaters

  • They don’t need gas lines built inside of your home
  • Propane is a lot cheaper than electricity
  • They use clean burning and it’s safe for all households
  • They last up to 10 years more than electric heat pumps
  • More efficient than electric heaters
  • Easy to install
  • No regular maintenance needed
  • Have a built-in thermostat

What Is The Difference Between Direct Vent and Ventless Propane Heaters?

There are two types of propane wall heaters – ventless and vented.

The main difference is that ventless heaters don’t need outside air for operation. They use oxygen from the same room they’re positioned in.

Ventless propane wall heaters usually have oxygen sensors, so they automatically shut off if the limit is reached.

On the other side, we have vented (direct-vent) propane heaters that are safer and work at higher elevations.

Still, I recommend you learn if you can use your propane heater indoors.

You won’t have to worry about carbon monoxide (which you don’t have to worry about with ventless heaters too), but they’re usually a bit harder to install.

It’s hard to tell which one is the best, although I’m an “all about the safety” type of guy – so I’ll usually choose vented before ventless propane wall heaters.
