While we are talking about home heat, Is it better to run your central heater up to the desired temp when you first come

I have mine programmed to kick up an hour or so at wakee-uppee time on weekdays. Every other cycle (4 zones/day) sets it back down to 45.
The rest of the time it's treated as "on demand" and set manually when desired. This year I might raise the minimum during the cold cold snaps (first frozen pipe in 7 years last year) but otherwise this arrangement seems to work great, and coming in from riding a bike in the cold to a 50-something degree house is pretty comfortable.
