Not when you have been away for two weeks in the sun, and come home to a house that is 6c inside.
And if it does only take 15 mins to heat up, then what is the harm in turning it on 15 mins before you get home?
If you lead a variable lifestyle, time wise, then stuff like this is a huge convenience, and probably won't cost you any more than regular heating controls. Possibly less.
