What is a Wall Heater?

Published in Heating System Component 3 mins read

A wall heater is a small electric heater that is installed directly into the wall of a room and used to heat that individual space.

Understanding Wall Heaters

Wall heaters are distinct from portable heaters or central heating systems. As their name suggests, they are designed to be a permanent fixture within a wall. This integration offers a space-saving heating solution, making them particularly popular in rooms where floor space is limited or where supplemental heat is needed.

Based on the provided information, these units are typically:

  • Compact: Often sized around 9-by-12 inches on the front panel.
  • Shallow: Usually about 4 inches deep, allowing them to fit within standard wall cavities.
  • Electric: Rely on electricity to generate heat.

Key Functions and Applications

Wall heaters serve two primary purposes:

  • Primary Heat Source: In smaller homes, apartments, or specific building sections (like additions or garages), they can serve as the sole method for heating individual rooms. Multiple units would be strategically placed throughout the property to provide warmth.
  • Supplemental Heating: In homes already equipped with a central heating system (like a furnace or heat pump), a wall heater can provide additional warmth to a specific room that might feel colder than others. This is useful for drafty rooms, infrequently used spaces, or areas requiring extra comfort without increasing the temperature for the entire house.

Benefits of Wall Heaters

  • Space-Saving: Installed in the wall, they don't occupy valuable floor space.
  • Zoned Heating: Allows you to heat individual rooms independently, potentially saving energy by not heating unused areas.
  • Quick Heat: Often provide quick, direct heat to the immediate area.

Typical Installation Locations

Wall heaters are commonly found in:

  • Bathrooms
  • Bedrooms
  • Living areas
  • Home offices
  • Additions or sunrooms
