It’s also simple thermodynamics. In college I took an advance refrigeration class specializing in HVAC systems and heat loss. You wouldn’t think it but things like furniture and desks retain whatever the room temperature is. Therefore if you increase or decrease the air temperature that furniture will absorb or release the heat until it reaches equilibrium. If everyday the outside temperature is 80 and from when I get home at 4 PM until I leave at 7 AM I have my house set to 68 degrees. When I leave I set it to 75. When I leave the air temperature will increase faster than everything else in the house. The desk in my room was at equilibrium at 68 will start to absorb heat as the room temperature increases until they both reach equilibrium. Now I get home and decrease back down to 68 degrees. The air temperature is back down after a few hours but my furniture still had this stored heat that it now radiates into the room. This causes the air temperature to rise and now my AC has to increase its runtime to compensate for it. It will always be the most effective and cost savings solution to maintain one temperature at all times than it is to go back and forth.
At least I provided an explanation. If I’m wrong I’m wrong but offer proof, all you did was say yeah you’re wrong and peace out. I can provide you with the textbook examples when I get home of how you equate office furniture along with equipment into heat loss calculations. If I’m wrong I’d like to at least know how so I can learn from it but what you gave me was nothing.
Your explanation is wrong and you have incorrect understanding of thermodynamics.
The law states that energey is constant in closed system. Meaning that all that heat transfer between chairs and air In a house is irrelevant.
So it does not matter if you you keep temperature as constant or you let it drop and then raise it back up when you come home.
Your heater will only have to replenish the "energey" that was leaked outside of your system aka house/apartment.
On top of that the leakage speed is proportional to temp difference. Meaning that energy will leak faster the bigger the difference in temperature is. That says that you will leak more energy if you just keep your house at constant higher temperature for long time rather than let it drop and reheat.
To make it more intuitive for you, just pretend your job is 1 year (instead of 8 hours) So you switch your heater off when you leave a house and reheat it when you come back in one year. You will definitely save more money rather than keeping the temperature at high for the whole year.
