The Importance of Proper Gas Pressure in a Furnace

There are numerous parts of a gas furnace that must be carefully synchronized and optimized in order for your heating to proceed efficiently. One of the most important considerations is the pressure of the incoming gas. If you would like to learn more about how gas pressure affects the overall performance of a furnace, read on as article will discuss the importance of proper gas pressure.

Gas Flow to Your Furnace

If gas were to simply flow into your furnace’s combustion chamber at the pressure it was entering your home through the gas company supply line, chances are your furnace wouldn’t operate very efficiently. One of the many functions performed by your furnace’s gas valve is to help regulate the pressure of the incoming gas, closely tailoring it to the needs and abilities of your furnace. Over time, however, it is necessary to test your gas pressure to ensure that it still falls within the optimum range, otherwise unwanted problems may ensue.

Problems with Gas Pressure to Your Furnace

If the gas pressure is too low, your furnace’s efficiency will go down. Not only that, but it will lead to a greater amount of condensation of burned gases. That is because the proportion of air in the air-fuel mixture will be too great. This condensation tends to accumulate inside of the heat exchanger, where it will eventually lead to the formation of corrosion, thus necessitating the replacement of this vital component.

High gas pressure can be just as bad for your furnace. That’s because it greatly increases the risk of furnace overheating. When this happens, all manner of internal components may become damaged by the excessive heat. Thus it is important to have your gas pressure tested and, if necessary, adjusted, on a fairly regular basis.
