Gain All the Heater Knowledge You Possibly Can This Winter

The basics of heater knowledge can help you understand your heating system and gain a general insight about any problems that might occur. Conversely, if you’re in the market for a new heater, you’ll be better prepared to make informed decisions if you read the heater knowledge below.

Forced-air gas furnaces make up the majority of central heating systems in our region. They are efficient, reliable, and typically deliver a long service life. By the numbers, here’s a basic primer of heater knowledge and how it warms your home effectively and safely.

  1. Natural gas from the utility company is regulated by a furnace valve that reduces gas pressure to just half a pound per square inch. The gas valve is controlled by the thermostat, which signals the valve to open when heat is required to maintain your indoor temperature settings.  
  2. Inside the furnace burner, an electronic igniter lights the mixture of gas and air, producing a bright-blue flame with a temperature exceeding 3,000 degrees.
  3. Heat generated by the burner flame is contained within the heat exchanger, a critical component made of copper or stamped steel. The heat exchanger’s material conducts heat into the system airflow while also keeping hazardous combustion gases like carbon monoxide out of the airflow.  Gases are instead safely diverted up the furnace vent pipe into the outdoor air.
  4. The blower fan in the air handler pulls filtered air through the furnace, then pushes it into ductwork that branches into rooms throughout the house. As it leaves the furnace, system airflow is typically between 140 and 170 degrees.  
  5. Furnace ductwork is divided into supply ducts that deliver heated air to rooms and separate return ducts that remove cooling air and return it to the furnace for reheating. The total length of a typical residential ductwork system is anywhere from 30 to 90 linear feet. 
  6. As the desired thermostat setting is reached, the thermostat signals the gas valve to close and the furnace shuts down until the next heating cycle.
