A panel heater, often referred to as a convection heater, is an electric heating appliance designed to efficiently warm indoor spaces primarily by circulating heated air. These modern heaters are known for their slim, discreet design, making them a popular choice for various residential and commercial settings.
How Panel Heaters Work: The Principle of Convection
Panel heaters derive their name as "convection heaters" because they heat a room almost entirely through the process of convection. Inside the heater body, hot metal elements warm the surrounding air. As this air heats up, it becomes less dense and rises, creating a natural air current. Cooler, denser air from the room then sinks to take its place, drawing it into the heater to be warmed in turn. This continuous circulation of air around the room ensures that the warm air spreads evenly, effectively transferring its heat to the occupants and objects within the space. This method of heat distribution provides fast and effective room heating.

Key Characteristics and Benefits
Panel heaters offer several advantages that contribute to their widespread use:
- Rapid Heating: Due to their reliance on convection, panel heaters can quickly raise the ambient temperature of a room, providing almost immediate warmth.
- Efficient Heat Distribution: The continuous air circulation ensures heat is distributed throughout the room, eliminating cold spots more effectively than radiant heaters.
- Sleek Design: Their typically slim profile allows them to blend seamlessly into modern interiors, often mounted unobtrusively on walls.
- Quiet Operation: Unlike heaters with fans, panel heaters operate silently, making them ideal for bedrooms, offices, or other quiet environments.
- Temperature Control: Most panel heaters come equipped with built-in thermostats, allowing users to set and maintain a desired temperature, which can help with energy efficiency. Many also feature timers for scheduled operation.
Where Are Panel Heaters Best Used?
Panel heaters are incredibly versatile and suitable for various applications:
- Supplementary Heating: They are excellent for boosting the temperature in rooms that tend to be colder than the rest of the house, or for providing extra warmth during peak cold periods.
- Bedrooms: Their silent operation and precise temperature control make them ideal for creating a comfortable sleeping environment.
- Home Offices and Studies: They provide focused warmth in individual workspaces without disturbing others or incurring high central heating costs.
- Guest Rooms: Easily switch on for temporary warmth when guests are staying.
- Small to Medium-Sized Rooms: While effective, they are generally best suited as the primary heat source for smaller spaces or as a supplementary source in larger ones.
Understanding Panel Heater Features
To make an informed decision, consider the following common features found in panel heaters:
| Feature | Description | Benefit |
|---|---|---|
| Heating Method | Convection (hot metal elements warm air, which then circulates) | Fast, even heat distribution |
| Installation | Wall-mountable (often with included brackets) or freestanding (with feet) | Flexible placement, space-saving |
| Thermostat | Built-in control to maintain desired room temperature | Energy efficiency, consistent comfort |
| Timer | Allows for pre-setting on/off times (e.g., wake-up, bedtime) | Convenience, energy saving by heating only when needed |
| Safety Features | Overheat protection, tip-over switches, child locks | Enhanced user safety |
| Display | Digital or analogue interface for settings (temperature, modes, timer) | Easy readability and control |
| Power Output | Measured in Watts (W), indicating heating capacity (e.g., 1000W, 2000W) | Match heater size to room size for optimal performance |
| IP Rating | Indicates water resistance (important for bathrooms, e.g., IP24) | Safe use in specific environments |
