Optimise your thermostat settings
Set your thermostat to the lowest comfortable temperature. For every degree you lower the thermostat, you can save a significant amount on heating costs. When you're away or sleeping, consider lowering it further and use blankets or extra layers to stay warm.

Seal drafts and insulate
Prevent heat loss by sealing drafts around windows and doors. Weatherstripping, caulking, and using draft stoppers can help minimize cold air infiltration. Adequate insulation in walls, attics, and basements also contributes to maintaining a warm indoor environment.
Use sunlight to your advantage
Open curtains and blinds during the day to allow natural sunlight to heat your home. Close them at night to insulate against the cold. Utilizing sunlight strategically can reduce the need for artificial heating during daylight hours.
Harness the power of ceiling fans
Use ceiling fans to your advantage. By reversing the direction of your ceiling fan to clockwise during winter, you can push warm air down from the ceiling, making the room feel cozier. This allows you to set your thermostat a bit lower without sacrificing comfort.
Dress in layers
Instead of relying solely on your heating system, dress warmly with layers of clothing. Wearing cozy sweaters, socks, and blankets indoors allows you to maintain comfort at lower thermostat settings.
Maintain your heating system
Schedule a professional inspection and maintenance for your heating system before the winter season kicks in. Clean or replace filters regularly, as a well-maintained system operates more efficiently and consumes less energy.
Seal fireplace flues when not in use
An open fireplace flue can act as a chimney, letting warm air escape and cold air enter. Ensure that the flue is tightly sealed when the fireplace is not in use to prevent heat loss.
Use energy-efficient lighting
Replace traditional incandescent bulbs with energy-efficient LED or CFL bulbs. These bulbs not only consume less energy but also emit less heat, contributing to a cooler indoor environment.
Limit heat-generating activities
Appliances such as ovens, stoves, and clothes dryers produce heat when in use. Plan your cooking and laundry activities during the colder parts of the day to take advantage of the additional warmth they generate.
Upgrade to energy-efficient windows
If feasible, consider upgrading to energy-efficient windows. Double-pane or triple-pane windows with low-emissivity coatings provide better insulation, preventing heat loss and reducing the workload on your heating system.
