Wall Heaters 101: Your Complete Guide

Electric Wall Heater in Bathroom

Wall heaters are heating units that are installed in or attached directly to a wall. They are most commonly used in studio apartments, compact living spaces and smaller offices, because they generate a good amount of heat suitable for keeping small areas warm, yet don’t take up any valuable floor space. In the early 1950s, wall-mounted heaters became a common alternative to baseboard heaters and portable space heaters in apartment buildings and home designs.

Let’s take a closer look at how an electric wall-mounted heater can keep you warm, and save your money at the same time.

The Evolution of the Wall Heater

The wall heater was derived from the radiator. Radiators used boilers to heat water that flowed through the pipes of homes and apartment buildings. The water pipes led to radiator units made from cast iron, in turn heating the space. While there are many buildings and homes that still use radiators today, their popularity declined with the introduction of the gas heater.

Gas heaters are installed directly on the walls, allowing for free-flowing heat. Gas heaters are lit from the bottom using a pilot light. They are a low-cost alternative to electric wall heaters. Early gas wall heaters required a ventilation system, but the ventless gas wall heater was invented later to eliminate the additional ventilation that posed problems for some people.

Electric wall heaters followed the gas heater and continue to be a front runner in space-heating options. They consist of a metal body and an internal heating element. Early heating elements consisted of porcelain bricks, and as the designs evolved, tubes or heating coils replaced the traditional methods. The heating element is heated through the electrical current, and heat is expelled into your living space via the wall unit.
