It's polar vortex season again, and as biting weather and snowstorms keep us inside our homes, we want to be as warm and cozy as possible, so we turn the heat up. But it's important to avoid wasting a chunk of your paycheck on a heating bill every winter.

This is easier in newer properties as they're more likely to have been built with efficiency in mind, with double-glazed doors and windows and thermal insulation that helps stop the heat you've paid for escaping into the outside world.

Have your furnace inspected

you should have your furnace inspected each year, just like a chimney. You should also consider having your air ducts cleaned or cleaning them yourself. Make sure you're also changing your furnace filters regularly to keep your furnace working properly.

Reverse ceiling fan blades

If your home has ceiling fans, you should switch the blade rotation with the seasons for best results. In winter, switching the blades to clockwise rotation on the lowest setting can push the warm air in the room down from the ceiling to keep you warmer.

Replace those old windows with better ones -- or get good drapes

While we're on the subject of expensive options, let's talk windows. Replacing old windows can be a good way of keeping the heat in, especially if those old windows have single panes of glass. Double glazing is much more heat-efficient.

Unfortunately double-glazed windows are not cheap. If replacing the windows is not an option, consider using thicker curtains which, when closed, can help seal off the window and stop drafts from getting in. Additionally, most local hardware stores sell easy to install window shrink wrap kits.  These add an extra layer of insulation, to help keep drafts away.

Add some layers of clothes 

It might sound obvious, but simply dressing for warmth when you're at home can save you a lot on your heating bills. And perhaps you already do, but there are many of us who are guilty of sitting at home on a winter's evening in a T-shirt thinking "I'm a bit chilly, actually" and then whacking the heating up. 

Instead, perhaps having a nice stack of fluffy sweaters or some lovely knitted blankets could help give you that cozy feel without the expense of turning your heating up higher.
