Unit Heaters – Electric, Gas & Hydronic Heating Solutions
Unit heaters are self-contained heating systems that deliver powerful, targeted warmth without requiring extensive ductwork. Perfect for warehouses, garages, workshops, and industrial facilities, these versatile heaters combine heating elements with fans to circulate warm air efficiently throughout large spaces.
What Are Unit Heaters?
Unit heaters are compact, standalone heating systems designed to heat specific areas directly. Unlike central heating systems, these heaters mount on walls or ceilings and deliver immediate warmth where you need it most. They're ideal for spaces with high ceilings, frequent door openings, or areas that need occasional heating.

How to Choose the Right Unit Heater Size
Step 1: Calculate your space volume (Length × Width × Height)
Step 2: Consider insulation quality:
- Good insulation: multiply by 4
- Average insulation: multiply by 5
- Poor insulation: multiply by 7
Step 3: Account for special conditions:
- Frequent door openings
- High ceilings
- Outdoor exposure
Example: A 30' × 30' × 10' garage (9,000 cubic feet) with average insulation needs approximately 45,000 BTU/hr.

Can I use a unit heater in a residential garage without ductwork?
Yes, unit heaters are self-contained and don't require ductwork. They mount easily to walls or ceilings and provide direct heating.
What's the difference between a unit heater and a space heater?
Unit heaters are mounted permanently and designed for larger spaces with powerful blowers. Space heaters are portable and better for smaller, enclosed rooms.
