Energy-Efficient King Electric Unit Heaters

King Electric Unit Heaters – Reliable Heating Solutions

King Electric unit heaters deliver reliable, energy-efficient heating for warehouses, garages, shops, and commercial facilities across North America. With over 60 years of manufacturing excellence, King Electric offers CSA-certified electric unit heaters built for demanding environments where consistent performance matters.

What is a Unit Heater?

A unit heater is a self-contained heating system that combines heating elements with a fan to distribute warm air throughout a space. Unlike central heating systems, electric unit heaters mount directly on walls or ceilings, providing targeted heating exactly where needed. They're ideal for large open spaces, workshops, and areas where traditional heating isn't practical.

How to Size Your Unit Heater

Basic Sizing Formula

BTU Required = Square Footage × 30-60 BTU per sq ft

Use 30 BTU/sq ft for well-insulated spaces, 60 BTU/sq ft for poorly insulated areas or high-ceiling applications.

Example Calculations

20' × 30' garage (600 sq ft): 18,000-36,000 BTU required
40' × 60' warehouse (2,400 sq ft): 72,000-144,000 BTU required
50' × 100' facility (5,000 sq ft): 150,000-300,000 BTU required

Professional Sizing Considerations

Ceiling height over 10 feet requires additional capacity
Frequent door openings increase heat loss and require a higher BTU capacity
Poor insulation or extreme climate conditions may also require larger heaters
