Inside an electric convector heater there is a large heating element similar to - but bigger than - one of the elements inside a bread toaster.

When the electricity is switched on the element gets hot and heats up the air that is all around it.

Because hot air is lighter than cold air, the hot air rises up and comes out, into the room, through the grilles at the top of the heater. Cold air from the room moves in through the grilles at the bottom of the heater to take the place of the hot air, and this process continues for as long as the heater is switched on.

Any movement of air in that way - cold air taking the place of hot air moving up - is called "convection", which is why the appliance is called a convection heater.

Electric fan heaters work in a different way: they have a powerful electric fan inside, which sucks in cold air from the room. The fan then blows the air through an electrically heated element and that hot air then comes out of the fan heater into the room.

Where does air flow into a convector heater?

from below the heater

On a convector heater where does the air flow into it?

If there is no fan to pull the air in, fresh air must come into a convector heater from below. It is drawn in because the air heated by the heating element is warmer and therefore lighter than the colder air below it. So the warmer air rises to leave the convector heater from the top.

Why is there a metal grill at the top of a convector heater?

It allows air to circulate through the heater while switched on.

Why is A radiator is not a good name for a heater of that name because?

this is because the major heat transfer in it, is convection.and it is better to name it convector.

Want to install a convector type heater in basement. Only available wall is above a cold air return to furnace. Will the cold air return distrurb the convector functionality or vice versa?

It shouldn't unless they are both drawing air from the same source.

How does a convector heater function?

A convector heater works by using a heating element, usually electric, to warm up the air surrounding it. The warm air rises and creates convection currents, which circulate the heat throughout the room. As the cool air is drawn into the heater, it gets heated and rises, creating a continuous flow of warm air.

Which type of motor is used in heat convector?

The fan in a convector is usually a single-phase induction motor.

What happens inside a convector heater?

A convection heater works on the principle of air convection currents circulating through its body and across its heating element. Heating element heats up the air, causing it to increase in volume and become buoyant. A convection heater can have an electrical heater element, a hot water coil, or a steam coil.

If you fix paper decorations to the wall above a convector heater they flutter when the heater is switched on Why does this happen?

This happens because the heating wires heat up the air around them. This air is less denser than the surrounding, and so it rises up through the top of the heater. If the paper decorations are above the heater, they will definitely flutter because the air is coming through the top.

What is convector?

A heat exchange device that uses the heat in steam, hot water, or an electric resistance element to warm the air in a room; often called inaccurately, a radiator. Essentially, it's a space heater that transfers heat to the surrounding air by convection. And, just as an interesting side fact, in Roman mythology, the god Convector oversaw the bringing in of the crops from the fields.
