What to look for when buying an indoor heater

Before investing your hard-earned money in an indoor propane heater there are several things you should give some thought to. Here they are.

Heat output

The primary consideration is the heat output of the heater. This needs to be in relation to the size of the room that you wish to heat. Larger rooms will require a higher output. With propane heaters, this is measured in BTU or British Thermal Units. 

The logical point is that an indoor propane heater with a higher BTU output will be able to heat a larger area. Take some time to consider the size of the space you wish to heat and purchase one that is capable of heating the area. 

You also want one that is adjustable so that you can dial in the perfect heat for ideal comfort. 


Following on from the above, you do not want to need to constantly turn the heater up or down. An integrated thermostat will make your indoor propane heater more user-friendly as it will automatically shut down or start according to the temperature of the room or area. 

The heater should have a range of settings. On colder evenings you might want a lot of heat and on other occasions, you might simply need a bit of warmth. 


This is another important factor to consider. You are limited by the space available in your room. You do not want the heater to be in the way. A compact heater is often essential if you have limited space. Sometimes, the best propane wall heater is the best solution (link to wall heater article).

If you want to be able to move the heater from room to room, size and weight become even more important. A portable (link to portable propane heater article) propane heater is light and easy to move around.  Some have handles or castors to make them easy to move and position. 

Wall mount option

While most propane house heaters are portable and can be moved from room to room. This is convenient and makes the unit more versatile. Many are light and compact. Some come with an option to wall-mount the heater. While you sacrifice portability this method will take up less space. 

If you do not have a need to move the heater around consider a neat unit that is fixed to the wall. It is safe, neat, and takes up less space. It is normally very easy to mount the heater and most that offer this feature come with the bracket needed.


The style of the heater is important when looking at the best indoor propane heaters. You do not want to have something that looks unpleasant in your home. Some have a sleek modern design while others are more traditional.  You get heaters that look like a natural fire which works in some spaces. 

The style of your home will determine the best look for your needs. 

Energy Efficiency 

The more efficient the propane heater, the less you will spend on running costs. The design, heating technology, and build will determine the energy efficiency of the heater. Some are a lot more efficient than others. The cost of the unit is only one factor. Give some thought to the long-term running costs of the model.  

Naturally, the unit will use more propane on full heat than it would on a lower setting. It also uses more if the ambient temperature is low as it will have to work harder and burn more propane to get to the desired heat. 


Many people have safety concerns when it comes to indoor propane heaters.  Fortunately, this need not be a concern. All quality heaters have multiple safety features that make them perfectly safe to use indoors. 

Features such as an ODS ( oxygen depletion sensor) and tip-over protection ensure that they are safe. Remember that the room still needs to have some form of ventilation. 

If you still have concerns you can always invest in a carbon monoxide sensor. They are inexpensive and will give you an extra layer of protection. 

Follow all the instructions and use the propane heater correctly. Make sure all hoses and connections are correct and in good repair. Have some form of ventilation. If you do this the propane heater is safe to use indoors. 

Durability and reliability

These two go together as both are based on the build quality and the quality of the workmanship. When investing in an indoor propane heater you want to know that it will work when you need it to and not fall apart after a year or two. 

Check out the quality of the heaters as well as the reputation of the company that makes them. A warranty will give you extra assurance that the unit is built to last. 


One always has to consider the budget, particularly if you need to invest in several indoor propane heaters. Prices range from affordable to somewhat expensive. The more costly units will probably have a better design, greater heat, and perhaps more features. 

There are many quality options that do not cost a fortune. Avoid the bargain basement models as they will not perform well and will probably not last very long.  Rather invest in one that will last for a while and deliver the heat necessary, otherwise, you will be disappointed. 


Are there are different types of indoor propane heaters? 

Yes, there are a few. The main types are infrared or radiant heaters, blue flame heaters, and vent-free heaters. Radiant heaters will radiate heat and warm objects which warm the room and those in it. Blue flame heaters make the air warm so that the area is more comfortable.  Vent-free heaters burn efficiently to warm the area. 

Another type of propane heater is a forced air heater although these are not popular for indoor use apart from a garage or workshop. 

Are propane house heaters safe to use indoors? 

Yes, modern propane heaters are perfectly safe to use indoors. They have safety standards and features that make them perfectly safe when used correctly. Remember that you always need some ventilation. Do not run a propane heater in a room with no ventilation. 

The basics that you need are overheating protection, tip-over shutoff, and an oxygen depletion sensor. 

Are propane heaters less expensive to run? 

All other factors being equal it is less expensive to warm a room with a propane heater than an electric heater.  This does depend on the design and style of the heater as well as the nature of the space to be heated but in general, it will cost less to run propane than electricity for heating a room. 

How long will an indoor propane heater run for?

This will depend on several factors. Below is an approximate guide.  

BTU Sq feet Operational Duration

  • 6,000 BTUs 200 1 Hour
  • 12,000 BTUs 400 1 Hour
  • 18,000 BTUs 600 1 Hour
  • 24,000 BTUs 800 1 Hour
  • 30,000 BTUs 100 1 Hour

The usage depends on the insulation of the room. Curtains, carpets, insulated windows all help to retain warmth in increase the operational time. Tiles, skylights, and multiple open windows will reduce performance times. Remember that you must have some ventilation. 

The ambient temperature is another big factor as the heater will have to work harder when it is very cold. However, A good thermostat will help to regulate usage and keep costs down. Nevertheless, Some design and heating technologies also make the unit more energy efficient and this will help to reduce the running costs over time. 

Do I need a carbon monoxide sensor if my heater has ODS?

While ODS is an important feature in all indoor heaters it does not offer full protection. Poor ventilation, a faulty heater or connections, or other causes could still result in an excess of carbon monoxide. For complete peace of mind, a carbon monoxide sensor is not a bad idea. They are not expensive and are easy to use.
