Unit Heater

Definition

A unit heater is a device used to heat a space without the use of ductwork.

Purpose

Unit heaters are designed to provide localized heating in areas where installing a full ductwork system is impractical or unnecessary. They offer efficient and targeted heating for various types of spaces, including commercial, industrial, and residential environments.

Examples of Use

• Warehouses: Installing unit heaters in large open spaces like warehouses to provide efficient heating without extensive ductwork.
• Garages: Using unit heaters in residential or commercial garages to maintain a comfortable temperature during colder months.
• Workshops: Heating small workshops or production areas where specific zones require heating rather than the entire building.

Related Terms

• Space Heater: A portable or fixed heater used to heat a small area or room.
• Radiant Heater: A heater that emits infrared radiation to directly heat objects and people in its path.
• Convection Heater: A heater that warms the air and circulates it through a room.

Notes

Unit heaters come in various fuel types, including electric, gas, and oil. They are often equipped with fans to distribute warm air evenly and can be ceiling-mounted, wall-mounted, or freestanding.
