Heating and cooling are some of the most energy-intensive applications in a home and also the most costly in terms of electricity, gas, oil or even wood consumed.

The cost isn’t just financial. All that energy has to come from somewhere and unless your house is supplied with green energy indirectly or has a substantial solar panel array; heating and cooling often has a substantial environmental impact in terms of greenhouse gas emissions via power generation.

Ceiling fans – summer and winter

While you may be familiar with using a ceiling fan during summer, have you considered using it in winter also?

As heat rises, most of the warmth you want is close to the ceiling during winter. A ceiling fan on a low speed can help push that heat down to where you are. Additionally, it can help reduce the instance of condensation on your windows.

During winter the fan will need to run clockwise, which is the opposite of the direction you want it running in summer. The reason for this is that as cold air is denser, running the ceiling fan clockwise draws that cold air up, pushing the warm air close to the ceiling aside, which then travels down the walls to a lower level of the room.

Using as little as a hundred watts, an ultra-efficient ceiling fan can shave up to 10% off your heating costs.

Ceiling fans really come into their own over summer though and work particularly well in dry areas. By moving the hot air around, it promotes evaporation of perspiration on your skin which has an cooling effect – making you feel up to 8 degrees cooler. Our bodies have very efficient cooling systems that we interfere with by wearing clothes. While it’s generally frowned upon to get around with your kit off, if you’re at home alone, who is going to know! Still, even clothed, you’ll reap some benefits in using a ceiling fan.
