It never costs more to heat or cool a thing as needed than to maintain a continuous temperature, at least from an energy consumption standpoint. That's why turning the thermostat off when everyone leaves the house saves energy compared to maintaining a continuous temperature.

The law of entropy causes heat to disburse, and the greater the temperature differential, the more rapidly that occurs. Allowing temperatures to drift towards equilibrium when not needed means less continuous heat transfer.
