For best energy conservation, should I turn my heat off at night and then turn it on in the morning?

   relative old furnace = your gonna pay regarless.

   newer furnaces now are energy star rated. they are modulating (old furnaces either run at 100% of its gas consumption or 0%)…modulating furnaces with modulating thermostats will have sensors that determine how much gas is required to heat your home in 5 percent intervals, generally have about 13 different levels of heating. this can save you about 40% on your gas bill alone.

   newer furnaces are high efficiency (90% +) meaning for every dollar you spend on your gas bill, at least 90 cents goes to heating your home, only 10 cents up the chimney. older furnaces range in the 78% area when initially installed and after many years become less efficient. you can save a good 20% on your gas bill here as well.

   newer furnaces have blower motors powered by DC voltage (direct current)…comparable to how a battery works, these suckers run on less then 24V, they are cheaper to run then a lightbulb. older furnaces blower motors run on 120V AC (alternating current), much larger wavelenghts…very expensive, like running a stove top, or refrigerator. running a DC motor 24 hours a day 7 days a week will cost you roughly 7$ a month, 120V AC motors, over 30$ a month, that’s a savings of about $350 a year on your energy bill

   so once you get into the hi efficiency, modulating furnace, with DC motor, you collect energy grants and the government will offer you rebates for being so environmentally friendly.

   other things to consider are getting an automatic central panel humidification system (cost less money to heat moist air then it does to heat dry air) as well as a good filtration system. both of these will assure you of never getting sick so long as your in your house.
