Heating costs can often be reduced in winter by using less energy without making the home uncomfortably cold. The biggest savings usually come from preventing heat loss, using the heating system efficiently, and adjusting everyday habits.
Improve Insulation and Stop Heat Loss
A poorly insulated home can lose a significant amount of heat through the roof, walls, windows, and doors. Check for obvious drafts around window frames, doors, and other openings. Weatherstripping or draft seals can help reduce unwanted cold air entering the home.
If possible, improve insulation in areas such as the attic or roof space. Keeping doors and windows properly closed when the heating is running also helps retain warm air.
Curtains can provide another simple layer of insulation. Close them after sunset, particularly on cold nights, but open them during sunny periods when sunlight can naturally warm the room.
Adjust the Thermostat Carefully
Instead of keeping the heating at a high temperature all day, choose a comfortable setting and lower it when the home is empty or when everyone is sleeping.
A programmable or smart thermostat can make this easier by automatically changing the temperature according to a schedule. Even small adjustments can reduce unnecessary heating, although the exact savings depend on the home, heating system, weather, and energy prices.
Avoid repeatedly turning the heating very high to warm a room quickly. It is generally more practical to maintain a reasonable temperature and heat only when needed.
Maintain the Heating System
A heating system that is not maintained properly may use more energy than necessary. Keep heaters, radiators, vents, and other heat outlets free from furniture, curtains, or other objects that block airflow.
For systems that use filters, such as many forced-air heating systems, check the manufacturer's instructions and replace or clean filters as recommended.
If a boiler, furnace, heat pump, or other heating appliance appears to be malfunctioning, have it inspected by a qualified professional rather than trying to make major repairs yourself.
Heat Only the Spaces You Need
If several rooms are rarely used, there may be little reason to heat them as much as occupied rooms. Where the heating system allows it, adjust individual room controls appropriately.
However, avoid letting unused areas become extremely cold if doing so could create problems such as frozen pipes, dampness, or condensation. The appropriate minimum temperature depends on the building, climate, plumbing, and heating system.
Use Warm Clothing and Bedding
Simple habits can reduce the need to increase the thermostat. Wearing a sweater or warmer indoor clothing, using suitable blankets, and keeping feet warm can make a moderate indoor temperature feel more comfortable.
At night, good bedding can also provide warmth without requiring the entire home to be heated to a high temperature.
Take Advantage of Sunlight
During sunny winter days, open curtains or blinds on windows that receive direct sunlight. The sunlight can provide some natural warmth.
Once the sun goes down, close the curtains to create an additional barrier between the room and the colder window surface.
Avoid Common Energy-Wasting Habits
Some small habits can unnecessarily increase heating costs. For example:
- Leaving doors or windows open while the heating is running.
- Blocking radiators or heating vents with furniture.
- Heating empty rooms unnecessarily.
- Ignoring drafts around doors and windows.
- Setting the thermostat higher than needed.
- Delaying routine heating-system maintenance.
A Practical Approach
Start with the inexpensive changes first. Seal obvious drafts, keep doors closed, avoid blocking heaters, adjust the thermostat sensibly, and use curtains and warmer clothing. Then consider larger improvements such as better insulation, more efficient heating equipment, or upgraded windows if they make financial sense for your home.
The best combination depends on the type of heating system, the home's insulation, the local winter climate, and energy prices. Focusing on reducing heat loss is usually a good starting point because it can lower the amount of heating required while also making the home more comfortable.
