What Are Propane Heaters?

Propane heaters are heaters that use pressurized propane gas as a fuel source to heat an area. An igniter starts the burning process of the gas and there is an element, usually porcelain bricks, that heats up and spread the warmth. This causes the element to give off a faint glow that is visible in the dark.

The reason that propane is used is because it is the most environment-friendly gas to burn. It is also the best heater to use during hunting because propane is an odorless gas so it has no smell when it is burned. If there is a smell, it is because there is a leak in the propane gas which causes a chemical compound known as mercaptan to be released. This gives off a rooting egg smell and allows the user to know that there is a leak in their propane heater.

With the fuel inside the heater, you will not be able to smell the mercaptan as it mixes well with fuel such as propane. It is also added to alert users of a possible leak, even if the leak is very small.

Can Deer Smell Propane Heaters?

Due to their keen sense of smell, a deer can definitely smell the fumes from the propane heater. While it may be odorless, deer have a sense of smell so strong it can detect if there is propane gas being burned. What’s more, deer can see the faint glow of the propane heater, especially in the dark. And if you have a broken propane heater or it breaks during your hunt, a deer can smell the leak even more.

Another thing, deer have a good sense of hearing as well. A propane heater low on fuel or on the point of breaking down will make a lot of noise. And this noise can definitely alert a deer and make them not approach an area. But can the smell alone scare the deer away?

Can The Smell of Propane Scare Deer Away?

In short, the smell of propane won’t scare the deer away. But it is a little more complicated than that. Deer that are accustomed to the smell of gas being burned, for example near farms, will not be scared away. But there are other factors that you might need to consider when you are burning propane in a heater, some good and some bad.

Good

  • The heat generated by propane heaters causes the air around them to rise. This is good because your scent will be carried along with the heated air and this could be used as an advantage against deer.
  • A good propane heater will not give off a smell that will scare away deer. The fumes from a propane heater are too small for a deer to take notice of. Even though they have a very good sense of smell, they will be more careful around the smell of hunters and predators than the smell of propane burning.

Bad

  • Propane can leak, and the smell from the leak will scare deer away. The mercaptan added to fuel is to alert the user of a leak, but deer can smell this rotting egg smell from miles away.
  • Heat amplifies your smell. The problem with heat is it makes your scent more noticeable. And if you are set up in a position where the deer are downwind of you, then your they can definitely smell you.

As always, it comes down to your positioning more than anything else during a hunt. Propane heaters can mask your smell by carrying it upwards with the heated air. However, be on the wrong side of the wind and a deer coming downwind of you will be able to smell you because the heat is amplifying your smell.

And of course, you would want to make sure that your propane heater is in the best condition possible. An old propane heater will be more likely to leak than one that is new or well-maintained.

  • Setting up blinds: More than the smell, you want to block the light that the heater will give out so you want to set up blinds to block the deer’s visions. Be sure to the blind away from places that the deer use as their paths as it might spook them.
  • Making sure that the heater is not low on fuel: A propane heater low on fuel will start to make a lot of noise. So always make sure that the propane heater has sufficient fuel before going out on your hunt.
  • Size of the heater: For a longer session, you would obviously want a larger heater so you can be warmer for longer. But a larger heater produces more heat and glows brighter. So choose accordingly.
  • Indoor propane heater: Check if your propane heater can be used indoors without any problems. An enclosed space while hunting can keep you warmer for longer and also make your propane less noticeable.
