Setback Thermostats Do Save On Your Fuel Bill
An automatic setback thermostat with a high efficiency furnace saves a lot of fuel
Thermostats are, as we know the device which is used to control the heating (and cooling) system in a home or other building. A setback thermostat can automatically change the temperature settings during the night, and during the daylight hours when you are out of the house. A properly used setback thermostat can cut energy useage considerably. When combined with a high efficiency furnace a setback thermost delivers the maximum savings in energy useage.
An ordinary thermostat maintains the home at a set temperature all the time. There is no variation at night time unless you manually turn down the temperature to a lower level. When you set your ordinary thermostat to a certain fixed temperature, it will start the furnace running as the temperature drops below that set temperature, and will then shut down the furnace after the temperature gets above the set level . Whether used with a gas furnace, oil furnace or electric furnace the controls work in the same way.
A setback thermostat is a more complex device with an electric clock inside to control temperatures at various times of the day. This thermostat can be set to turn down the temperature in the evening at a pre-selected time for the duration of the night,and it is also set to turn temperature down in the daytime, when the home occupants are not there.
It can also be programmed to raise the temperature level up to a higher level in the morning when you arise for the day, or at the time when you are due to arrive home from the days duties. You can thus save energy by means of a lowered temperature without the suffering any discomfort of having to wait for the house to warm up when you want it to.
Will Setting Back The Temperature Save On Your Fuel Costs?
It has been well demonstrated that winter temperature setback using an automatic setback thermostat can bring savings of five to fifteen per cent in heating costs for most homes. The maximum savings are obtained when a high efficiency furnace is used, in combination with a setback thermostat.
These savings are dependent on your having a properly insulated and air-leak free home. If your insulation is poor you will get considerable energy savings by upgrading it. In fact poor insulation is the greatest source of wasted energy in most homes which are not well insulated. Air leaks at various points around the home will also cost considerably in increased fuel consumption.
