Convection Floor Heating

You require less installed capacity in a radiant heating system.

Convection floor heating.

For example your gas boiler central heating system is a perfect example of a predominantly convection based system. The thin layer of molecules in direct physical contact with the object heat up through the process of conduction and causes them to expand. The main benefit to convection heaters is that they are good at heating an entire room for an extended period of time. If your house has two floors you often end up with the bottom floor being cooler than the top floor.

This general sensation of comfort is further enhanced through conduction feet on floor and through convection by the surface s influence on air density. As they do they move up and away from the object displacing the cooler denser molecules above them. They should be used in closed spaces. In most cases convection heaters are silent.

Find the right space heater for your needs with our expert advice. Convection heaters heat the air and then transfer the heat throughout that space to warm up people and physical objects. You don t need to run it as long. You can apply heat only where you need it you don t need to heat the whole room.

Convection heating occurs when a warm object is placed in a fluid medium like water or air. Convection heat transfer grows only linearly with temperature. With convection heaters of any kind the temperature of each room can be controlled individually. Convective heat transfer often referred to simply as convection is the transfer of heat from one place to another by the movement of fluids.

As the heated air rises the cooler air on the floor is drawn into the convector creating a constant flow. 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. Air is blown over a heating element and then the warm air circulates through the room. Heat transferred watts metre second grows exponentially with temperature rise.

Convection is usually the dominant form of heat transfer in liquids and gases. The heating of the surfaces suppresses body heat loss resulting in a perception of heating comfort. These are the best space heaters you can buy according to consumer reports exhaustive tests. Although often discussed as a distinct method of heat transfer convective heat transfer involves the combined processes of unknown conduction and advection.
