ceiling fansceiling fans conserve energy -------------- ceiling fan

Ceiling fans can reduce heating bills

When air is heated, it becomes less dense and rises. As a result, warm air becomes trapped at ceiling level. Installing ceiling fans to push this warm air back towards floor level can reduce heating bills by up to 30%.

Ceiling fans reduce heating costs by:

Reducing heat loss through the roof and walls
Increasing the temperature at floor level, allowing thermostats to be turned down
Reducing the heat load required, permitting smaller heaters to be used

Ceiling fans are inexpensive to purchase and install, and use negligible amounts of energy (less than a standard light bulb per fan). In most cases, the reduction in heating bills is such that payback is achieved in less than a year.

Ceiling fans in industrial buildings

Ceiling fans are most effective in buildings with ceilings higher than 4.5m. They are widely used in industrial buildings such as factories, warehouses, workshops, etc. Slowly rotating ceiling fans return the hot air in the roof space to the occupied space below, providing draft free even air distribution of warm air throughout the workspace.

Ceiling fans improve summer working conditions

During the summer, ceiling fans run at high speed to create a cooling breeze, for occupants working below.

Determining the number of ceiling fans needed

Ceiling fans should be equally spaced throughout the room to ensure uniform air distribution. They should be installed at least 5m away from the walls.

The number of ceiling fans depends on the mounting height, (ceiling height less the length of the down rod). Use the following table to determine the number required:

Ceiling fan spacing vs. height
Mounting Height  m 4 6 8 10 12
Distance Apart  m 5 7 8 9 10

Safety restrictions

There must be at least 2.3m between the bottom of the fan blades and the floor. Ceiling fans should be installed so that they do not interfere with other equipment.

Ceiling fan and controllers - electricity supply requirements

Our ceiling fans and controllers require a 230V single phase 50Hz electricity supply. They are suitable for use in the UK, most of Europe, Eastern Europe and the Middle East, but not the USA.


Our ceiling fans and electronic controllers are manufactured to the highest standards, and we are confident that they are totally reliable. However, in the unlikely event a fault may occur, they have a full 1 year return to base parts and labour guarantee. Contact our sales dept.

For more information or a quotation on our ceiling fans

Ceiling fans significantly reduce the running costs of all types of warm air heating, especially fan heaters and convectors. Installation and running costs are minimal, often leading to payback within a year. Consideration should be given to installing ceiling fans in any premises where the ceiling height is greater than 4.5m.
