HVAC - Heating question..

To all the pros and I guess home owners other there..



what uses more energy?

Heating your home 21c all day and night or

Have a program to turn off your home heat from 9 AM to 6 PM then off again 11PM TO 730AM [ off by means of temp set to 17c ]

I have been beating my head in the wall for days now..



any one have any insight ?

thanks
