How Does Portable Heater Work?

Heater uses convection ceramic heating technology to deliver targeted, personalized heat wherever you point the device. It’s angled up for comfortable use when you place it on a desk or floor.

Another important thing I want to point out in this review is that it’s safe for kids and pets. The power button is actually located on the back of the heater. None of the other buttons on the device will work unless the power button has been activated.

The next step in the heating process depends on whether or not the heater has a built-in electric fan or not. If there is a fan, it will help draw cold air into the heater. The air passes over the heating elements and then is pushed out into the room — this is similar to how hair dryers work. This is also known as convection heating because the warmth is transferred through the air. Convection heaters are a good way to warm a space quickly by getting hot air to circulate around the room

If there is no fan in the heater, air enters the unit from below. The air flow passes over the coils, is heated and finally finds its way out through the top of the device. This style of electric heating is known as radiant heating — think of a conventional electric stove with a heating element. It’s a good choice for small spaces and areas where you can be near the heat source while it’s in use. Electric baseboards are radiant heaters and provide an effective way of introducing thermal energy to a room without changing the infrastructure of your home.
