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

[decocritter]

Which is more efficient, run the heat continuously to desired temp, get the house comfortable (reasoning once you run the heat for a few minutes the ducts are warm and stay warm until house is warm) Thinking the house will slowly lose heat during the night and you will be going to bed anyway, and don't need it so warm.

or Set thermostat lower than Ideal temp and it cycles on and off (ductwork cools in between, so has to warm up each time) but it runs less time and uses less gas.

Am I making any sense?
