What is a wall heater?

Wall heaters, as you may have guessed, are units that are installed inside the wall of a room. Unlike traditional gas furnaces, wall heaters can be easily installed as there is no blower motor or ducting involved.

• More Facts about Wall Heaters
  • Installation of Wall Furnaces
    • Wall furnaces are typically installed by licensed furnace specialists due to the potential risks associated with gas units.
    • Installation of a wall furnace does not require ductwork, making it a simpler process compared to traditional forced-air furnaces.
    • Wall furnaces can be mounted on any inside or outside wall, fitting between any standard 16” center stud space.
    • Installation by non-certified persons is strictly prohibited and can void all warranties.
  • Safety Measures for Wall Furnaces
    • Modern, properly-installed wall furnaces are remarkably safe, but like all heat sources, they come with risks.
    • It’s recommended to have a furnace technician do annual inspections of your unit to ensure it’s functioning properly.
    • Furnaces have safety features such as a Flame Rollout Sensor, a Flame Proving Sensor, a High Temperature Limit Control, a Flue Exhaust Pressure Sensor, and a Fan Limit Sensor.
    • Gas units involve more risk than electric, because there is the possibility of gas leaks and carbon monoxide poisoning.
  • Efficiency of Wall Furnaces
    • Wall furnaces are energy-efficient, with some new models achieving thermal efficiencies of 80-94%.
    • They are much more powerful units than common electric portable space heaters, and they can be used as a primary source of heating in energy efficient homes, even in cold climates.
    • The oldest existing furnaces have thermal efficiencies of 50% while today’s standard replacement wall furnaces have thermal efficiencies of 70%.
    • Advanced technology drives these clean-burning wall furnaces to more than 80% efficiency (AFUE).
  • Types of Wall Furnaces
    • Wall furnaces can generate heat from one of three sources: an internal electric element, the home’s natural gas line, or a liquid propane gas tank stored on the property.
    • There are vented wall furnaces that use room air to support combustion and exhaust their flue products to the outdoors via a single pipe.
    • Direct-Vent systems mount on an outside wall and have a vent-within-a-vent system to draw in outdoor air to support combustion and exhaust flue products to the outdoors.
    • Gravity Wall Furnaces mount on any inside or outside wall, providing both circulated and radiant heat in an economical package
