Yes, it does. And turning it off entirely at night would save even more.
I tried that for a while this Fall and the colder it got, the longer it
took to get the house warmed up to where it was approaching comfortable.
And there was a strong temptation to set the thermostat higher than normal
to get it to stay warm sooner.

Ummmmmmm...... except in a very few cases with specialized
heating systems [a], moving the thermostat to a higher temperature
isn't going to speed things up.

I don't think that's what she said. If you want the temp to be 70, then
set the t-stat to 80. It will cycle once or twice, then set it to 70. This
is from a "cold" start where the temp is way below the setting. It takes
time to bring the furnishings, &c up to temp, so having the t-stat set at
80 helps with this. Yes?
