Should You Leave Your Thermostat On One Temperature Or Change It?

A thermostat goes a long way to keeping your houses comfortable during the freezing winter weather and the scorching summer heat. However, people handle these gadgets differently. There are those who micromanage their temperature settings, varying it continuously. The majority set it at one temperature and does not think of it again.

Consequently, the most commonly asked question is on the benefits, if any, of fixing the thermostat at one temperature for the whole day.

Yes, there are both pros and cons of such a strategy. Here is a look at both.



People leave their thermostats at constant temperatures for various reasons. Some do so because they find it sufficient for their comfort needs. Others just do not want to go around messing with it. There is also the lazy lot who only check their thermostat when the room becomes extremely uncomfortable. Either way, constant thermostat temperature setting is done for convenience. However, keeping your thermostat’s setting constant is only wise when you are leaving home for a vacation or the weekend.


As earlier mentioned, convenience is the main reason for constant temperature setting. Such a plan, however, comes short of energy efficiency and savings on your bill.

Here is how;


Heat energy leakage

In most cases leaving the thermostat temperature constant is aimed at keeping the thermal energy (heat) inside the homes constant. Consequently inside the house will often be warmer than the outside.

A standard heat law is that; heat is transferred from a region of its high concentration to region of low concentration. An example is a heat moving from the end of a metal rod in a fire to its other cooler end. As a result, the heat energy required to maintain the temperature at the hotter end include the energy “leaked” to the other end. Again, the higher the temperature difference between the two points the faster the heat loss to the surrounding.

The same applies to house temperature. The warmer it is more than the outside, the more rapid energy leaks out as heat to the surrounding. Leaving it so for long hours wastes even more energy.

Therefore, if you are concerned about saving energy, you can do the following.


1. 8-hours routine

If your home is to be unoccupied for long hours during the day, consider resetting the temperature every 8 hours. You can set it as you leave in the morning and reset it when you get back. As per calculation, you can save up to 15% annually on energy costs.

When you are out, the temperature should be a few degrees lower than outside to minimize heat leakage. You may be thinking that heating a cold house takes a lot of energy. Yes, it does, but it is certainly lower than that leaked out when the house is kept warm all the time.


2. Get a Programmable Thermostat

It is the ultimate solution to home heating problems. After a few days of routine adjustment, the thermostat will begin doing the work for you. Studies show that those who let it do the job for them save more than thermostat micromanagers.

Putting it together;

First, constant temperatures setting on thermostat wastes energy unless it is lowers than outside. Secondly; you can save more energy by using a programmable thermostat.
