What Are Electric Radiators and How Do They Work?

Electric radiators are a popular heating option that uses electricity to generate heat and distribute it across a room. They come in various designs, but most feature a heating element inside that heats up when powered. The heat is then transferred to the surrounding air or stored in a thermal mass (like ceramic or oil) within the unit, which continues to radiate warmth after the radiator has turned off.

Most modern electric radiators come with built-in thermostats and digital controls, allowing you to set and maintain a specific temperature in your room. Some advanced models even offer Wi-Fi control, meaning you can adjust the temperature from your smartphone or smart home system, ensuring your home is always at the perfect temperature when you need it.

What are Electric Panel Heaters?

A panel heater is a flat, wall-mounted electric heater unit designed to warm up rooms through natural convection currents as the heat rises from its surface. These heaters come in the form of single panels that emit convection heat only.

Panel heaters operate by utilizing heating elements inside the unit that get hot when switched on. This heat is then transferred to the air in the form of convection heat and expelled via the top grill (a bit like a large hair dryer).

Some types of panel heaters incorporate infrared technology, allowing them to absorb and radiate energy as heat more efficiently without losing it through ventilation, although this type of heating can create cold spots in a room.
