Convective heat transfer often referred to simply as convection is the transfer of heat from one place to another by the movement of fluids.
Convection floor heating.
The advantages of radiant heating over convection.
Heat transferred watts metre second grows exponentially with temperature rise.
If your house has two floors you often end up with the bottom floor being cooler than the top floor.
Air is blown over a heating element and then the warm air circulates through the room.
Tapping into a natural phenomenon known as convection air inside a convector is heated becoming less dense than the surrounding cool air enabling it to rise due to buoyancy.
Convection heating occurs when a warm object is placed in a fluid medium like water or air.
In most cases convection heaters are silent.
With convection heaters of any kind the temperature of each room can be controlled individually.
For example your gas boiler central heating system is a perfect example of a predominantly convection based system.
You can apply heat only where you need it you don t need to heat the whole room.
The thin layer of molecules in direct physical contact with the object heat up through the process of conduction and causes them to expand.
Find the right space heater for your needs with our expert advice.
In substances where convection is free to take place that is in gases and liquids hotter material naturally ends up on top and cooler material ends up on the bottom because of the higher buoyancy of the hotter material.
Convection heaters can also be recessed into the floor which means they can be placed directly in front of a stairway or floor to ceiling windows.
As the heated air rises the cooler air on the floor is drawn into the convector creating a constant flow.
You require less installed capacity in a radiant heating system.
Convection heat transfer grows only linearly with temperature.
This general sensation of comfort is further enhanced through conduction feet on floor and through convection by the surface s influence on air density.
Most space heaters are convection heaters meaning they rely on the circulation of air to heat a room.
You don t need to run it as long.
Although often discussed as a distinct method of heat transfer convective heat transfer involves the combined processes of unknown conduction and advection.
Convection heaters heat the air and then transfer the heat throughout that space to warm up people and physical objects.
These are the best space heaters you can buy according to consumer reports exhaustive tests.
Convection is usually the dominant form of heat transfer in liquids and gases.
The main benefit to convection heaters is that they are good at heating an entire room for an extended period of time.
