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. With global energy prices on the rise, making our homes more energy-efficient can cut our energy bills, save us money and reduce our carbon footprint.
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.
Check out insulation options for walls and the roof
While older properties (including my own) may have no insulation built in as standard, it is possible to still add this in. Houses lose a great deal of heat from the roof, so adding insulation here can be a great start. It's even possible to buy insulation (in rolls or even as boards) and install it yourself.
The walls are another matter entirely and will require the insulation to be affixed either to the interior walls, with a false wall erected within to create the cavity or a new rendered wall created on the outside of the building. For period homes where the original walls are part of the character, this latter option simply won't fly -- especially if your home is historically listed, like mine, where there is a particular focus on maintaining the exterior aesthetics of the property. Other insulation options can include materials inserted beneath the floorboards.
Adding insulation to the property can be a great way to increase energy efficiency, but it can also be a big outlay and potentially very disruptive to install. Thankfully there are many insulation specialists who can advise on your best options.
Replace those old windows with better ones -- or get good drapes
While we're on the subject of expensive options, let's talk windows. Many period properties boast extremely large windows that may offer lovely views and allow in plenty of natural light, but can also let a lot of heat escape in the colder months. Replacing old windows can therefore 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.
Check that the rubber seals are in good condition too. If there are any gaps where air can get in, the sealant could always be replaced without having the expense of replacing the whole window.
Unfortunately double-glazed windows are not cheap, especially on period properties. Replacing the windows in my property would likely be over $30,000, which is simply money I do not have to spare. 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.
Seal or cover drafty areas
If your house has areas with drafts, it's going to be even more difficult to keep the heat in, so it's important to hunt down those problem areas and plug them up well. Usually you'll be able to tell where they're coming from, and it's typically worse anywhere that separates the inside from the outside. Drafts around exterior doors are common, especially if you have an older door.
Consider sticking foam draft tape around the inside of your door frame so your door creates a tight seal when closed. If your door has a letterbox, make sure it has a draft excluder (a sealed box or bristles that stops air getting through), and if there is a gap under the door then get a draft stopper (one of those long sausage-shaped cushions) to help keep the drafts at bay.
Again, checking the seals around your windows is important. And don't forget about using thicker curtains.
Keep interior doors closed
It's one of the cheapest and simplest things to do, but keeping your interior doors to your rooms closed can make a big difference in heating your home. It has two benefits. First, it helps keep any errant drafts under control and stops them seeping into your cozy living room and giving you the chills.
Second and even more important, it keeps the heat in, meaning if you have the heating (radiators or stand-alone heaters) on in your living room, that heat doesn't escape, meaning less money spent overall. Extra bonus if those interior doors are also sealed with draft-proof tape.
Get a smart thermostat and upgrade your radiator valves
Your home's central heating is usually the best way to warm the place up, but older systems tend not to be particularly efficient and often end up heating the whole home needlessly and at times when you don't even need it.
But you can take it a step further with smart radiator valves too. Smart valves, like the Hive ones I'm using, allow you to heat up only the specific rooms you need at specific times -- the bedroom and bathroom in the morning and the living room in the evening, for example -- meaning no energy is wasted on heating up rooms you're not using.
As with smart valves, using a small, portable heater can be a more efficient way to heat only the rooms you need. This can be especially useful for those of you working from home, when you can use a simple plug-in heater that will direct a flow of warm air just to you, rather than having to turn on your home's central heating system.
I found that the Philips 2000 Series 3-in-1 heating fan does a great job of adding an extra blast of heat when I need it, with the benefit that it also filters the air and acts as a cooling fan in the summer months. I've also found the DeLonghi Dragon 4 oil-filled panel radiator great for quickly heating up my home office as it's quick to heat up and maintains its heat for some time after being switched off. Plug-in fans and panel heaters might not always be super energy efficient if you leave them on 24/7, but they can be great for giving a warm boost without having to heat the whole home.

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.
