Different types of convection heaters: Convection heaters come in several types, including portable electric convection heaters, wall-mounted convection heaters, oil-filled radiators, and fan-assisted convection heaters, each designed to efficiently circulate warm air in a room, providing consistent heating suitable for various spaces and needs.
Convection heaters warm spaces by circulating heated air, making them ideal for consistent, even heating. Unlike radiant heaters that target objects directly, convection models heat the air itself, creating a comfortable environment for extended periods. This guide explores the various types of convection heaters, their unique features, and best applications.
How Convection Heaters Work
Convection heaters operate on a simple principle: cold air enters the unit, passes over a heating element, and rises as it warms. This creates a continuous cycle of air movement. The heated air gradually displaces cooler air, resulting in uniform temperature distribution. For more details on this process, see our article on how convection heating works.
Key Components
- Heating element (electric coils, oil, or gas burner)
- Air intake vents
- Thermostat for temperature control
- Safety features (tip-over switch, overheat protection)
Main Types of Convection Heaters
1. Electric Panel Heaters
These slim, wall-mounted units use electric coils to heat metal panels. The panels then warm surrounding air through natural convection. Modern versions often include:
- Precise digital thermostats
- 24/7 programming options
- Wi-Fi connectivity for smart home integration
Best for: Bedrooms, home offices, and small living spaces where quiet operation and space-saving design matter.
2. Oil-Filled Radiators
These portable heaters use electricity to heat diathermic oil sealed inside metal columns. The oil retains heat exceptionally well, allowing the unit to continue warming a room even after being turned off. Key features include:
- Silent operation (no fans)
- Excellent heat retention
- Adjustable thermostats
For a detailed comparison, see our guide on oil-filled radiator vs electric heater.
3. Ceramic Heaters
Ceramic heaters use electricity to heat ceramic plates, which then warm passing air. They come in two main configurations:
Natural Convection Models
These rely solely on air movement without fans, making them completely silent.
Fan-Assisted Models
These incorporate fans to accelerate heat distribution, warming rooms faster while generating some noise.

4. Gas-Fired Convection Heaters
These powerful heaters use natural gas or propane to generate heat. Common types include:
| Type | Best For | Venting Required |
|---|---|---|
| Vented | Large spaces, workshops | Yes |
| Ventless | Temporary heating | No |

Specialty Convection Heaters
1. Institutional Convectors
Designed for commercial and industrial use, these heavy-duty units feature:
- Rugged metal construction
- High-capacity heating elements
- Advanced airflow designs
Common applications: Warehouses, factories, and large retail spaces.
2. Baseboard Heaters
These low-profile units install along walls at floor level. They work particularly well as:
- Primary heat sources in well-insulated homes
- Supplemental heating in specific rooms
- Zone heating solutions
For installation guidance, see our baseboard heater installation guide.
Choosing the Right Convection Heater
Key Selection Factors
- Room Size: Match heater capacity (in BTUs or watts) to your space
- Energy Source: Consider availability of electricity, gas, or propane
- Portability Needs: Fixed vs. movable units
- Noise Tolerance: Fan-assisted vs. natural convection models
- Safety Features: Especially important for homes with children or pets
According to U.S. Department of Energy, properly sized electric heaters can be efficient for zone heating.
Safety Considerations
All convection heaters require proper safety measures:
- Maintain at least 3 feet clearance from flammable materials
- Never leave operating heaters unattended
- Install carbon monoxide detectors with gas models
- Use only with properly rated electrical circuits
For more on safe operation, see CPSC space heater safety guidelines.
Maintenance Tips
Regular maintenance ensures optimal performance and longevity:
- Clean air filters monthly (on models that have them)
- Inspect electrical cords for damage
- Wipe down exterior surfaces to prevent dust buildup
- Have gas models professionally serviced annually
Energy Efficiency
Modern convection heaters incorporate several energy-saving features:
- Programmable thermostats
- Eco modes that optimize power usage
- Motion sensors that adjust heating when rooms are unoccupied
- Open window detection (on some premium models)
