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
