- Turn down all your thermostats, including those on auxiliary heaters, by 1°C to 4°C at the start of a peak demand event. When you lower the temperature, your heating system turns off. The lower you set the temperature, the longer it stays off.
- Reset the thermostats to their usual temperature at the end of the peak demand event if a second event is expected later in the day.
Do you usually turn down the temperature overnight or during the day?
Don’t do it before a peak demand event, because you’d then have to turn the temperature back up in the morning or evening, right in the middle of an event—and you should definitely avoid doing that. But when there’s no peak demand event, carry on as usual.
Warning: If your heating system has trouble maintaining a normal room temperature (20°C to 21°C) in cold weather, this tip is not recommended for you. Keep in mind that the amount of time it takes to get back to the regular temperature after turning down the thermostat depends on how powerful your heating system is.
