How Does Temperature Differential Work?

When an HVAC professional in Burlington refers to temperature differential, it means the difference between the temperature in your home and the one outside. So, for example, your thermostat is set at 20°C inside and it is 0°C outside, there is a temperature differential of 20°C. When a door or window is opened, that warm air from outside makes its way outside, called “heat transference” and, before you know it, that cold air will affect the temperature inside. That heat transference will make the area near that open door or window require more time and energy to heat if the differential was less.

How Can Temperature Differential Affect Fuel Costs?

Since heat uses energy, the movement of heat is related to the amount of fuel it takes to provide it. This equates to fuel costs and fuel efficiency when considering our HVAC systems in Burlington. This is why we need to pay attention to that difference in temperature between the interior of a home and the outside temperature. The differential will determine how much heat is lost in a given period of time.

Does Lowering the Thermostat Save on Energy Costs?

Many homeowners will try to manage that temperature differential by setting the thermostat lower while they are away, or setting a less used area of the home lower in a zoned heating situation. There is almost always a debate surrounding that mentality. Is it really more efficient to set a thermostat lower when it will require that much more energy to return the area back to a comfortable 20°C?

Most experts feel that the energy needed to heat an area back up to the desired temperature compared to keeping it at a consistent temperature will save money on energy costs in the long run. When a thermostat is set back, the area will lose heat at a very slow rate. Conversely, when the thermostat is raised, the heat will return slowly as well. It is felt that the energy used to return a temperature is more than offset by the period of time where the home is being maintained at a lower temperature.

Try a WiFi Thermostat

If you are one of the homeowners who subscribe to the reducing the thermostat mentality, it is especially convenient to have a WiFi thermostat, or “smart” thermostat, so you will be able to control your temperature from your smartphone or computer. A WiFi thermostat can also offer features like intuitive schedules and automatic temperature changes when you are away from home.
