This is a question for the engineers on the list. I am not an engineer. I live in NW Ohio (cold). I have a separate garage/shop heated with a natural gas furnace. I normally set the temperature aroun

The greater the differential in temperature between the inside and the outside, the faster the garage will lose heat. Therefore, on a 25 degree day outside, your furnace will run more when the thermo

Probably about the same, but it take more energy to maintain the temperature at 60 degrees than it does to maintain 45 for the time you are not there... Tim Mullen

Setting the thermostat lower will save more if it's set back for the same amount of time. The difference comes into play when you have to set the temperature up far sooner in order to have the house

Off subject: Unless you have the stupid "smart" thermostat like the one on my furnace. It tracks how long it takes to warm up to a temperature at the time of day. So if you set it to 70 degrees at 7

Similarly off-topic. I've long wondered why residential HVAC systems don't have more sophisticated controls like commercial systems - thermostats that check the outdoor temperature and compensate acc

I've not looked into what's available, but it certainly doesn't have to be that way. The thermostat can "know" how long it takes the house to warm up with full heat applied, and get a new measuremen

I disagree. The savings will be less than if you set 70 degrees later, but you will always save more energy by using a lower setback temperature. Unless of course your setback temp is below ambient

Well, all that depends upon heat loss (Z factor) through the materials. The purpose of insulation is to slow that rate (which is why it's always more economical to put money into insulation than fuel
