Best Indoor Propane Heater – Buying Guide

Sometimes reviews aren’t enough to help you make a choice. You also need to know the essential factors to consider while selecting indoor propane heaters. The right choice can keep your home heated during an unpredicted power cut and on camping trips. 

Ignition type

Propane heaters come with two types of ignition types- manual and automatic. For automatic ignition, you need to push a button. In manual variants, you have to use a match to light the pilot light and create a spark.

Overall heating Capacity

The heating capacity plays a vital role as the sole motive of investing in a heater is to heat the room. Referred to as BTU, the British thermal unit describes the heating capacity of any heater. The higher is the BTU, the better is its heating capacity.

So look out for heaters with higher BTU if you want to heat a large area. For smaller rooms, heaters with lower BTU will suffice.


Portability is an important feature to remember if you plan to carry and use a heater in different places. For example, you can use it in other rooms as required, on your camping trips and even at job sites. 

Heat Settings

Most heaters have two or three types of heat adjustments to regulate the heat levels. For example, the heater may offer 4000 BTU/hour, 8000.BTU/hour and 12000 BTU/hours at low, medium, and high heat settings.

The propane fuel consumption rate is directly related to the heat settings. The higher the heating output, the more propane is consumed. So we suggest using the heater at low heat settings to save fuel and for fuel-efficiency.


The larger the heater, the higher it would clutter the space around the room. So you may have to consider the size if you are buying a heater for smaller rooms. A compact heater can be easy placed in any room irrespective of its size.

But the drawback is that most of the compact heaters lack power.

Hence, you may have to consider large heaters if you are looking for a heater with larger output. We suggest checking your room size and power requirement to decide on the best size.


Many propane heaters come with a caster to enhance portability. It facilitates the easy moving of heaters without lifting and carrying them from one place to another. Casters also facilitate the easy movement of heavy propane heaters.


The heater’s reliability depends on build quality, spare part availability, manufacturer warranty, and safety features. Lack of safety features makes the entire heater incompatible and useless over some time. Similarly, the unavailability of spare parts will make repairs challenging in case of any breakdown.

Manufacturer warranty vouches for the supreme quality of the heater and saves you from additional unnecessary maintenance costs over time. Build quality is significant in the right portable heater because low build quality leads to higher chances of damage.

Safety tips for Propane Heaters

According to the National Fire Protection Association, heating equipment is a leading cause of fire in most US homes. Hence, it is highly recommended to use space heaters to avoid such potential fire risks safely.

We have listed some propane safety tips to keep such accidents at bay:

  • Installing carbon monoxide and smoke alarms releases an alarm to warn you about alarming low oxygen levels. Test them every year to assess their competency.
  • It is worth adding a gas leak detector to your heater to avoid any potential risks associated with gas leaks.
  • Read the warning labels and manufacturer instructions carefully before use
  • Avoid letting children playing around the heater to avoid any mishap.
  • Ensure that the room you install the heater in has around 3 feet kids-free zone space from the heater
  • Propane heaters must not be used to warm beds, dry clothes, or thaw pipes. The heaters should only be used to provide supplemental and emergency heat.
  • Install the heater at the right place without obstructing any way.
  • Avoid using outdoor propane heaters as indoor heaters 
  • Always hire a professional to install the propane heaters properly 
  • Don’t forget to service your indoor propane heaters at least once a year

These tips assure the safe use of indoor propane heaters and lower their maintenance cost.
