5 Best Vented Propane Heater For Cabin

Cabins, especially log-house cabins, can make a beautiful extension to your home. They add a one-of-a-kind “guest house” to your property and can serve as the perfect getaway whenever you feel bored in the main house.

Unfortunately, the cabin also tends to get quite cold during the cold weather. If yours is a log-house cabin, it can become freezing cold during the winter weather.

A vented propane heater could be just what you need to turn that cabin into an all-year fun spot. Best vented propane heaters are low-cost (compared to other heating options), simple to install & use, and incredibly energy-efficient. They also come in varied styles and designs, adding a degree of charm to any living space.

What is a Vented propane gas heater?

Vented Propane Heater for CabinA vented heater has a venting system (usually in the form of a small pipe) through the back designed to serve as an exit path for exhaust gases. In most cases, the pipe exists through the wall, though sometimes it can vent through a chimney.

The bottom line is that these heaters provide a mechanism for exhaust gases to leave the fire chamber. Vent-free heaters don’t have this mechanism.

Advantages of Vented Propane Gas Heater

There are two main benefits of buying a vented propane heater over an unvented/vent-free propane heater;

  • Safety: This is by far the biggest advantage of vented gas heaters. No gas combustion process is 100% efficient. The process always results in at least a few exhaust gases, some of which are poisonous. In the case of propane heaters, one of the poisonous exhaust gases is carbon monoxide. A venting system provides an exit mechanism for these toxic gases.
  • Meets most code requirements: A quick check will show you that vent-free heaters aren’t allowed in most countries/states because of the inherent safety risk. By contrast, vented heaters are not only allowed but also encouraged by most administrations.

Types of Vented Propane Heaters

There are two main types of best vented propane heaters, i.e., direct vent propane and B vented propane heaters
. Here’s what you need to know about each option.

  • Direct vent heaters

The more popular of the two, direct vent heaters use a venting system designed by the manufacturer. Also, the venting system takes in air, and an exhaust system gets rid of any gaseous by-products. It’s also worth noting that direct vent heaters feature closed cooling systems, meaning that the propane heater won’t use up the home’s air for combustion.

  • B-vent heaters

Also known as natural vent heaters, B-vent heaters require that you manually install a vent pipe running through your home and exiting through the roof. They also depend on the air in your room for combustion. Of the two types, they are less expensive. However, they are also less efficient compared to direct-vent heaters.

Factors to Consider When Buying a Vented Propane Heater

Price is the first thing that comes to mind when shopping. However, don’t forget to consider the following factors too;

  • Power Capacity

The power capacity of a propane heater is measured in British Thermal Units (BTUs). For cabin heating, you’ll need at least 5,000 BUTs, though you’d need more for a larger space. The Department of Energy recommends 20 BTU output of heating energy for every square foot of living space though most experts say you need 40BTU/Sq. Ft.

  • Heating Efficiency

First off, it’s important to understand that vented heaters lose some heat through the venting pipes, thus aren’t as efficient as vented propane heaters
. Despite that, you should aim to get the most efficient propane heaters you can find. Anything above 95% efficiency is considered exceptional.

  • Radiant or Convectional Heating?

Radiant heaters heat objects directly. Convention heaters, on the other hand, heat the space surrounding the heater, then objects (such as you) absorb warmth from the heated air. Radiant heaters are more efficient, but convention heaters are better for warming large spaces.

  • Safety Features

What features has the manufacturer included to make the propane heater safe for use? Does it have an oxygen depletion sensor? What about an automatic shut-off mechanism? Other features to look for include cool-to-touch surfaces and compliance with national/international standards.

Mounting a Vented Propane Heater

There are several types of ventless propane heaters. This installation guide focuses on wall-mounted vented propane heaters
. Proceed as follows;

  • Choose where you want to install the heater: The best place to install a wall-mounted propane cabin heater is on the cabin’s back wall. This way, the heat generated is pushed towards the door. Determine the height where you want to install the propane heater and mark the point for the vent pipe. 
  • Screw the mounting bracket onto the wallHold the bracket against the wall over the area where you marked the vent hole. Then, insert screws and secure the bracket onto the wall.  
  • Drill the vent hole: Use a drill bit to make a hole through the wall. Depending on the size of the wall, this process may require significant effort. 
  • Place the heater into the brackets: As you do this, remember to slip the vent pipe through the hole you drilled earlier. Make sure the setup is secure and level. 
  • Connect the heater to the propane tank: This is accomplished by connecting the hose pipe coming from the heater to the one from the propane tank. You may need an adapter.

Once all the connections are secure, you can turn on the propane tank and then start using the heater by clicking the ignition button as necessary.

Safety Tips when Using a Vented Propane Heater

The safety of vented propane heaters starts with the features we mentioned earlier. Choose a heater that has an oxygen depletion sensor (ODS), automatic overheating shut-off, and that’s approved by ETL, Intertek, and other national/international standard organizations.

For additional safety;

  • Consider professional installation
  • Use standard venting pipes
  • Keep the propane tank outside
