The Convection Heaters

To understand convection heaters better, let me walk you through an overview. We’ll cover how convection heaters work along with the advantages and disadvantages they offer. In terms of functionality, convection heaters utilize the principle of air circulation to heat the room. Stay tuned to learn about the benefits and drawbacks of these heaters.

How Convection Heaters Work

Convection heaters use convection currents to spread the heat around a room. They have an electric heating element that warms up the air. This air gets less dense and rises, creating a natural circulation of warm air.

The heating element is turned on and heat is emitted. This warm air rises towards the ceiling. As it reaches the ceiling, it cools and falls back to the floor. This cooled air gets drawn back to the heating element and reheated. This cycle of warm air rising and cool air descending creates a convection current. This spreads the heat around the room.

Convection heaters are great because they heat an entire room. Unlike radiant heaters, convection heaters warm the air around them. This means the heat is evenly spread throughout the space.

To make the most of these heaters, you should consider insulation and positioning. Insulation helps keep the heat in, and you can place the heater near drafts or colder areas. This will help balance the temperature in the room.

Advantages of Convection Heaters
