Buying Guide

Type

There are two types of natural gas wall heaters, blue flame or infrared, they dissipate convection and radiant heat respectively.

Stand/Legs

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.
