Buying Guide

Most natural gas wall heaters look the same, but there are several factors that differentiate them. You should check those points before investing in any them. Some of these factors are mentioned and briefly discussed below.


How much are you willing to invest in a wall heater? Make a decision and filter your search options. Match the quality and features of a wall heater with its price. You do not have to overspend on a heating machine that has less BTUs or coverage area.


There are two types of natural gas wall heaters, blue flame or infrared, they dissipate convection and radiant heat respectively. A wall heater with blue flame will warm the air, which in turn moves up and slowly the entire room will be heated. On the other hand, a radiant heater heats the objects in the surrounding, which in turn heats the air. As per our experts, blue flame wall heaters are fast and efficient. So, make your choice putting into consideration this factor.

Safety Certification

You must have noticed that in most of the descriptions we used CSA certification. Well, it’s a Canadian Standards Association that tests and certifies a product only if it meets the US safety and performance standards. So, make sure you purchase a CSA certified product, which in our case is wall heaters.

British Thermal Unit (BTU)

The amount of heat a device can produce in one hour is measured in BTU. If you are willing to heat a large area, then you should look for a wall heater with high BTU. Similarly, for a smaller room, you can choose a heater with low BTU.


You can install a natural gas wall heater on the floor as well. For that, you will need the included legs or an option to add them. We suggest that you look for a wall heater with legs included so that you don’t have to invest extra on a separate item.

With the given guidelines, we are sure you will be able to find an appropriate and useful natural gas wall heater for your house.
