Types of Indoor Space Heaters
1. Infrared Heaters
Infrared heaters work by emitting electromagnetic waves that directly warm people and objects, similar to sunlight. They’re highly efficient, as they don’t waste energy heating the air. These heaters are perfect for spot heating—think living rooms or home offices. Plus, they operate silently, making them ideal for noise-sensitive spaces.

2. Oil-Filled Radiators
These heaters use thermal oil to retain heat, providing consistent warmth even after being turned off. They’re excellent for overnight use in bedrooms since they don’t dry out the air. While they take longer to warm up, their energy efficiency makes them a cost-effective choice for long-term heating.
3. Ceramic Heaters
Ceramic space heaters use a ceramic heating element and a fan to distribute warm air quickly. They’re lightweight, portable, and often come with adjustable thermostats. Their cool-to-touch exteriors make them safer for homes with kids or pets.
4. Micathermic Heaters
A hybrid between convection and radiant heaters, micathermic heaters combine quick heating with energy efficiency. They’re slim and lightweight, making them easy to move around. However, they can get hot to the touch, so placement matters.
How to Choose the Best Heater for Your Needs
Room Size & Heating Capacity
Match your heater’s wattage to your room size:
| Room Size (sq. ft.) | Recommended Wattage |
|---|---|
| Up to 100 | 750W |
| 100–200 | 1,000–1,500W |
| 200+ | 1,500W+ |
Energy Efficiency
Look for heaters with programmable thermostats and eco-modes to reduce energy consumption. Infrared and oil-filled models tend to be the most efficient.
Safety Features
- Tip-over protection: Shuts off if knocked over.
- Overheat protection: Prevents internal damage.
- Cool-touch housing: Reduces burn risks.
