This is very heat source dependent. With forced hot air and a furnace, your statement is false. It takes <10 minutes to warm up a house with this system.

My house goes from 62 to 68 in less than 10 minutes.

Maintaining 68 all day uses much more energy than heating the walls and furniture. Proof is the drastic cuts in my energy bills by using this method haha

Again, it’s heat source dependent. You may be correct for electric or hydronic heat which takes much longer to raise the temp of the room.

Temp rise, insulation, duty cycles are also important factors. Your blanket statement of maintaining 68 all day is better is incorrect.

Department of Energy disagrees: "During winter, the lower the interior temperature, the slower the heat loss. So the longer your house remains at the lower temperature, the more energy you save, because your house has lost less energy than it would have at the higher temperature."

The reason for smart/programmable tstats is exactly so you can set them for specific time periods? Running your heat when not needed (empty house) is a waste of energy. It’s the single marketing point for smart tstats. Even if what you say is true, the heating system is still not running nearly as much to where it would be if it was on all day.

This is just wrong info. It’s a simple equation. (Time system is on)x(cost of heat) = heating bill. So decreasing the time your system is on will decrease your bill. The furnace doesn’t “work herder” based on the room temperature.

I think it’s even a metric like for every degree you lower your tstat setting can save 1% in cost. Go to the DOE website and research thermostats. “You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7-10deg for 8 hours a day” Source: https://www.energy.gov/energysaver/programmable-thermostats

So what about the 8 hours/day 5days/ week you’re suggesting to keep it at operating temp? The heating system isn’t working during these hours? I don’t understand. Again, check out DOE website. Or just google your question. It’s debunked by multiple sources. Also, the reason for smart tstats is so you can set them for specific run times. It’s the whole purpose of a smart tstat

Not to be that guy, but a quick google search debunks this man… you’re saying in order to save money on heating, keep the system running 24/7. That just makes no sense
