There are several types of portable heaters available, including convection heaters, radiant heaters, oil-filled radiators, ceramic heaters, and infrared heaters, each offering different heating methods and efficiencies for various spaces and needs.
Portable heaters offer flexible heating solutions for homes, offices, and outdoor spaces. With various technologies available, choosing the right one depends on your space size, safety needs, and energy efficiency goals.
1. Ceramic Heaters
Ceramic heaters use a ceramic plate with aluminum fins to generate heat. A fan blows air across these heated surfaces, distributing warmth quickly.
Key Features:
- Fast heating – reaches desired temperature in minutes
- Lightweight and portable
- Cool-to-touch exteriors on most models
Best for: Small offices, bedrooms, or personal spaces. Learn more about ceramic vs radiant heating to determine which suits your needs.
2. Infrared Heaters
Infrared heaters emit electromagnetic radiation that directly warms objects and people rather than heating the air.
Types of Infrared Heaters:
| Type | Heat Range | Best Use |
|---|---|---|
| Near-infrared | Short range | Spot heating |
| Far-infrared | Long range | Whole room heating |
According to Energy.gov, infrared heaters can be 25-50% more efficient than conventional heaters for zone heating.
3. Oil-Filled Radiators
These heaters use electricity to heat diathermic oil sealed in metal columns. The oil retains heat well, providing consistent warmth.
Advantages:
- Silent operation – no fans
- Long heat retention after turning off
- Good for medium-sized rooms
Compare oil-filled vs electric heaters to understand which works better for your situation.
4. Propane Heaters
Propane heaters burn liquefied petroleum gas to produce heat, making them ideal for power outages or outdoor use.
Safety Considerations:
- Require proper ventilation
- Need carbon monoxide detectors
- Follow manufacturer’s clearance guidelines
The CPSC recommends keeping all flammable materials at least 3 feet from propane heaters.
5. Fan-Forced Heaters
These electric heaters use a heating element and fan to circulate warm air quickly throughout a space.
Ideal Uses:
- Quickly warming small to medium rooms
- Workshops or garages (with proper safety precautions)
- Areas needing temporary heat
6. Micathermic Heaters
Micathermic heaters combine convection and radiant heating using mica-covered panels.
Unique Benefits:
- Thin, lightweight design
- Heats up quickly like radiant heaters
- Continues warming after shutoff like convection heaters
7. Baseboard Heaters
These low-profile units mount along walls and provide steady, quiet heat through convection currents.
Installation Tips:
- Leave at least 3/4″ clearance from floor
- Don’t place furniture directly in front
- Consider adding a programmable thermostat for better control
8. Kerosene Heaters
These fuel-burning heaters provide substantial heat output but require careful handling.
Important Notes:
- Only use 1-K grade kerosene
- Always refuel outdoors when unit is cool
- Maintain proper ventilation
Choosing the Right Portable Heater
Consider these factors when selecting a heater:
Room Size
Measure your space and match the heater’s BTU rating. As a general rule:
- Small rooms (150 sq ft): 5,000 BTU
- Medium rooms (250 sq ft): 8,000 BTU
- Large rooms (400 sq ft): 12,000 BTU
Energy Efficiency
Look for Energy Star certified models when available. Infrared and oil-filled heaters typically offer the best efficiency.
Safety Features
Essential safety components include:
- Tip-over switch
- Overheat protection
- Cool-touch housing
- Child lock (for families)
