Many people assume that a ceiling fan is only really of use for a few hot weeks in the Summer. However, almost all ceiling fans have a reverse function that makes them useful in Winter too.

Warm air rises.
That’s the end of the science bit.
Your central heating warming the air in your various rooms and that air wants to go to the ceiling. In a conservatory with a pitched roof this warm air movement is more pronounced than in a room with a flat ceiling.
So, we have a lot of rooms that are warmed from the top down. This is inefficient.
A ceiling fan running slowly in reverse can redistribute this warm air at ceiling level, pushing it back down the wall and towards the lower part of the room where it is much more useful to you.
