Things to Consider Before Buying a Propane Wall Heater

As we have mentioned above, it’s critical to buy propane wall heaters from reliable brands. But something ls and you risk setting your homes in flames. 

Here are some factors to consider when buying propane wall heaters.

1. Safety features

These safety features will render ventless heaters safe for indoor use.

  • Oxygen depletion sensor

Ventless propane heaters have a risk of combustion due to the lower oxygen and increased carbon dioxide and monoxide levels. So to avoid this, you have to buy propane heaters that have an automatic oxygen depletion sensor. This safety feature will automatically turn off the heater once it senses that oxygen is dropping. 

  • Tip-over protection

Smaller ventless propane heaters have a risk of tipping over. And these supplemental heat solutions often come with legs to make them more stable.

  • Covers or caged wires

Another safety feature that you have to look for is the cover or cage wires. Vent free heaters should have either one of these. This will ensure that your clothes or anything else won’t catch fire. It avoids items from getting into contact with the heating element too. 

  • Overheat protection

Some units can produce high heat. An overheat protection will ensure that your homes won’t be caught in flames once propane wall heaters get too hot. 

2. Restrictions

Some ventless heaters such as Mr. Heater are banned in some countries like Canada. So before making a purchase, make sure that your country or location allows the use of ventless propane wall heaters. 

3. Btu

The BTU measures the heat output of these heating systems. A higher btu is capable of heating a large space. Ideally 30 000 btu is better for a large room.

4. Accessories

Not all vent free heaters come with all the necessary hardware and accessories that you need for the setup. Some may lack legs or a fuel hose. And when buying these fittings, you also have to buy from reputable dealers. 

5. Features 

A vent free propane wall heater with a thermostat ensures that you can enjoy consistent heating options. If you have kids and pets, go for ventless heaters that have surfaces that are still cool to touch.

So you have to read the labels carefully to see what features are included. 

6. Price

Whatever your budget is, you have a choice from premium to budget vent free heaters. More often, the higher the price, the higher the btu.

Vented vs Ventless Propane Wall Heaters

Vented Propane Wall Heaters

  • Vented propane heaters are more popular than the ventless models. Vented propane heaters vents gas to the outside of your homes via vent pipe.  
  • A major advantage of this model is that it prevents harmful gases from entering your home. 
  • But the downside is, you can also lose heat through the vents. 
  • And this can cause a spike in your utility bills.  
  • And since you’re throwing out gases into the outside air, it’s less eco friendly. 
  • It also involves laborious installation. It involves boring a hole into your walls.

  •  That means there is also no heat loss.
  • So it is more economical and can save you on utility bills.
