Winter energy costs depend on the home, province, weather, heating fuel, insulation, equipment, and household habits. A detached older home heated with electricity has a different profile than a newer apartment heated by natural gas or district systems.
This guide focuses on practical checks that are broadly useful and low-risk.
Drafts
Air leaks around doors, windows, outlets, pipes, and attic hatches can waste heat.
Thermostat
Small setting changes and schedules can reduce unnecessary heating.
Furnace filters
Dirty filters can reduce airflow and efficiency in forced-air systems.
Hot water
Showers, laundry, and dripping taps can quietly increase energy use.
Windows
Curtains and window coverings can help with comfort, especially at night.
Appliances
Space heaters and older appliances can add significant winter load.
Start with drafts
Draft sealing is often a high-value first step because warm air leaving the home must be replaced by cold air that needs to be heated. Weatherstripping, door sweeps, caulking, outlet gaskets, and attic hatch sealing can help when used appropriately.
Be careful not to block intentional ventilation or combustion air requirements. If a home has fuel-burning equipment, major sealing work should be considered with safety in mind.
Use thermostat changes carefully
Lowering the thermostat slightly can reduce heating demand. A programmable or smart schedule may help avoid heating the home more than needed when people are asleep or away.
Do not lower temperatures to a point that creates comfort, moisture, or freezing-risk problems. Homes with vulnerable occupants, pets, pipes in cold zones, or special equipment need caution.
Hot water is part of the winter bill
Shorter showers, cold-water laundry, fixing drips, and insulating accessible hot-water pipes where appropriate can help reduce hot-water energy use.
If a water heater is old or unreliable, use repair and replacement planning rather than waiting for an emergency leak.
Winter energy action table
| Action | Cost level | Why it helps |
|---|---|---|
| Weatherstrip doors | Low | Reduces drafts and heat loss |
| Seal obvious gaps | Low | Limits cold-air infiltration |
| Replace furnace filter | Low | Improves airflow and system operation |
| Use thermostat schedule | Low | Reduces heating when not needed |
| Open curtains on sunny days | Free | Captures passive solar warmth |
| Close curtains at night | Free | Improves comfort near windows |
| Fix dripping hot-water taps | Low to moderate | Reduces wasted heated water |
Winter home energy checklist
- Check doors, windows, outlets, and pipe penetrations for drafts.
- Replace or clean furnace filters as appropriate.
- Keep vents and returns clear.
- Use thermostat schedules sensibly.
- Close curtains at night and open sunny curtains during the day.
- Reduce hot-water waste.
- Review the bill monthly to see whether usage changed.

FAQ
What is the easiest winter energy saving step?
Draft reduction, thermostat habits, furnace-filter maintenance, and hot-water habits are often the easiest first checks.
Should I use space heaters to save money?
Use caution. Space heaters can be costly and can create safety risks if used improperly. Follow manufacturer instructions and do not use them as a substitute for a safe heating system.
Do small thermostat changes matter?
They can, especially over long winter periods, but comfort, safety, moisture, and freezing-risk concerns must come first.
