- Reduce the temperature by 2 to 4°C (3–7°F) at night
- Maintain a stable indoor climate to prevent the heating system from overworking in the morning
- Use a programmable thermostat to automate temperature changes during sleeping hours
This approach allows your home to retain some warmth, reducing energy consumption while avoiding the extreme cold that forces the system to use more energy later.
The Golden Rule for Night Heating
Experts agree: the golden rule is “lower, don’t turn off”.
- Lowering the temperature slightly saves energy and reduces bills
- Turning off heating entirely only works in specific conditions and may backfire in colder climates
- Smart thermostats or timers can maximize savings by adjusting temperatures based on your schedule
Additional Tips to Reduce Heating Costs
- Use Thick Curtains – Prevent heat loss through windows overnight.
- Seal Drafts – Weather-stripping doors and windows keeps warm air inside.
- Layer Bedding – Instead of heating the whole house, keep warm under blankets.
- Zone Heating – Heat only rooms you use at night, not the entire house.
- Wear Warm Clothing – Simple adjustments, like wearing a sweater or socks, reduce the need for higher temperatures.
Bottom Line
Completely turning off heating at night may seem economical, but for most households, slightly lowering the temperature is far more effective. It prevents energy spikes, maintains comfort, and ultimately reduces your energy bills without forcing you to wake up in a freezing bedroom.
By following the golden rule and combining it with insulation improvements, smart thermostats, and practical habits, you can enjoy warmer nights and lower heating costs all winter long.
