Don’t lower the temperature during the night and during the day preceding a peak demand event.
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 avoid doing that. But when there’s no peak demand event, carry on as usual.
Lowering the temperature by a few degrees at certain times is a good habit in terms of energy efficiency. But it’s not a good idea if you have shown interest in dynamic pricing, unless you are able to preheat your home before a peak demand event.
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.
