Convection heater how does it work
In most cases, convection heaters are silent. Convection heaters save about 10 per cent more in energy costs when compared to electric baseboard heaters. This can be a problem for people with dust allergies. If your home is big, then without a doubt it makes sense to have a central heating system rather than convection heaters in every bedroom.
A central forced air system provides heat quickly and filters the air. The down side is that it can spread dust and odours, such as cooking smells, from room to room. But the most convincing advantage of convection heaters is that they provide a comfortable kind of heat that warms your home quickly. National advertising powered by Mediative.

All about central heating systems. Is it wrong to rejoice in the benefits of heating with oil? In contrast, infrared heaters are mostly quiet. But when they run on full power, they can also produce noise. Infrared heater use infrared heating elements to produce radiant heat. If they run on lots of power, they can start buzzing or humming.
If you need an absolutely quiet heater, oil heaters which belong to the group of convection heaters are always the best idea. Some heaters produce light. Especially infrared radiant heaters. They usually heat using infrared heating tubes. To produce the heat, these heating tubes first have to heat up to a point where they glow red.
Yes, there are some convection heaters where you can see a glowing hot heating coil. But mostly the heating coil is hidden inside the body of the heater. So, if you want to heat overnight, and you prefer to have a dark room, then stick with convection heaters.
Convection heaters make use of the natural movement of hot air. They are, in fact, one of the most intuitive ways to heat. Convection heaters are a very basic approach to heating. They are less prone to errors and they are very cost-effective. Convection heaters also come in all shapes and sizes. From big tower heater that heats entire living spaces to small desk heaters that keep just your hands warm. Daniel is an electrical engineer, blogger, and author.
He studied electrical engineering and information technology and decided to blog about heaters after working in the temperature sensing industry.
How a convection heater works: The Basics Convection heat is not hard to understand. Here are the key differences: Heating speed Radiant heaters work in a completely different way than convection heaters.
Heat Retention Convection heaters heat the air. In contrast, infrared heaters lose their heat nearly immediately after you turn them off. Efficiency Convection heaters and radiant heaters are efficient in different scenarios. Light Some heaters produce light. So, all radiant heaters glow. The two most common space heaters on the market are convection heaters and radiant heaters.
Convection heaters warm the air. There are three ways to heat an object: conductive heating, convection heating, and radiant heating. Conductive heating occurs when objects of different temperatures come into direct, physical contact. Energy is transferred from the warmer object into the colder object until the temperature of both objects is exactly the same.
Convection heating occurs when a warm object is placed in a fluid medium, like water or air. The thin layer of molecules in direct, physical contact with the object heat up through the process of conduction and causes them to expand. As they do, they move up and away from the object, displacing the cooler, denser molecules above them. This is what is known as a convection current. There are five types of convection heaters: oil, ceramic, water, fan heaters, and furnaces.
Each works on the same principle but generates and distributes heat in different ways. When the ambient temperature drops below your pre-set level, it activates the heater.
Several convection heaters also come with timers, so you can program them to begin heating your home, office, or apartment before you arrive. As the name implies, radiant heaters work by generating infrared radiation. All objects radiate energy in some form, at a rate proportional to their temperature. The infrared energy from radiant heaters travels out in the invisible, electromagnetic waves that get absorbed by the objects in their path.
There are several different ways of generating radiant heat, reflected in the different styles of radiant heaters available for your home. Some are ordinary space heaters, while others are built into the house itself. Radiant heaters are also a popular way to heat bathrooms. Rooms with poor insulation, drafts, or high ceilings are very difficult to heat with a convection space heater.
Air is a poor heat conductor. Where radiant heaters struggle is any place where you want to move around comfortably in the same area. All of which makes them an excellent way to heat one or two individuals, but very bad at heating rooms. Convection heaters, though not as efficient, heat enclosed spaces very well, allowing you to move about without feeling cold or chilly. They can even be used outdoors.
