What Are HVAC Unit Heaters?
HVAC unit heaters are compact, high-performance systems designed to provide reliable heat to commercial or industrial spaces. Typically installed on walls or ceilings, they deliver warm air directly into the space using a fan-driven system. Unit heaters are ideal for warehouses, garages, workshops, distribution centers, and other large open areas where ducted systems may not be practical.
Types of Unit Heaters
There are several types of unit heaters available, each suited to different building needs and fuel sources:
Gas-Fired Unit Heaters: These use natural gas or propane to generate heat. They’re powerful and commonly used in large industrial settings.
Electric Unit Heaters: Best for areas where gas isn’t available, these heaters are easy to install and require minimal maintenance.
Hydronic Unit Heaters: These systems use hot water or steam from a boiler to provide radiant or fan-forced heat. Ideal for facilities with existing hydronic heating infrastructure.
Infrared Unit Heaters: These use radiant heat rather than blowing air, making them efficient in areas with high ceilings or frequently open doors.
Signs You May Need a New Unit Heater
Replacing an outdated or underperforming unit heater can improve comfort, reduce energy costs, and enhance workplace safety. Business owners should look out for:
Uneven or Inadequate Heating: If certain areas remain cold despite the unit running, it may be losing effectiveness.
Increased Utility Bills: A spike in heating costs may indicate your unit is operating inefficiently.
Unusual Noises or Vibrations: These could be signs of worn components or failing fans.
Age of Equipment: Most unit heaters have a lifespan of 10–20 years. If yours is approaching this range, it may be time to consider a replacement.
Frequent Breakdowns: Regular service calls can add up—upgrading may save money in the long run.
What’s Included in Unit Heater Maintenance Plans
Routine maintenance keeps your unit heater running efficiently, reduces downtime, and helps avoid unexpected repairs. A professional HVAC maintenance plan typically includes:
- Seasonal Tune-Ups: Pre-winter checkups ensure your heater is ready before cold weather hits.
- Filter Changes and Cleaning: Dust and debris can reduce airflow and efficiency—regular cleaning keeps performance high.
- Heat Exchanger Inspection: Prevents issues like carbon monoxide leaks or reduced heat output.
- Fan and Motor Checks: Ensures all moving parts are lubricated and functioning properly.
- Burner and Ignition Testing (for gas models): Verifies safe and efficient fuel combustion.
- Thermostat and Safety Control Testing: Keeps your system operating reliably and within safe limits.
