Home owners depend on their gas furnaces each and every winter to heat their homes. A gas furnace should be efficient as well as reliable, to keep the home as warm as possible each and every day. Furnaces use several electrical components to help improve the workability and efficiency of the unit and most operate the same.
One component of the furnace is the thermostat. Modern units use a digital thermostat which is connected to a thermistor. Once the temperature in the home falls to a certain degree, the thermistor will change and trigger the heating system to switch on. This process also works backwards so the unit will cut off once the maximum temperature is reached.
The heating process takes place in a furnace as part of the combustion chamber. This portion is sealed away and will draw air form the duct work that goes to the outside. It is very important for this portion to be set up correctly so the exhaust gases can be taken outside of the home to avoid health hazards inside the home.
The main return of the unit will pull air inside, which will be taken to the heat exchanger and then warmed and returned to the home to produce the heat in the home. The air will not be returned to the inside of the home until the air reaches the desired temperature. The air will then be returned to the home through a series of duct work.
The blower is a large fan that has enough power to move a large volume of air. The blower will draw the air in and then wait for the air to heat before it will distribute the air throughout the home through the duct work.
Overall, gas furnace heating systems work basically as they did from the first time they were created. However, technology has changed, making is easier for furnaces to be installed, repaired and maintained. The gas furnace option is a great choice to heat the home as it can quickly provide warm air during those cold winter months.
It is important to have a top quality HVAC dealer in your area that can provide you with the best in heating service options. Maintenance will ensure that your unit will continue to work as it should for years to come, providing you with an efficient and proper functioning heating system!
