Furnace heat exchanger life In this article we discuss residential forced warm air furnace heat exchanger life in more detail, explaining the factors that impact the life of the heat exchanger, things you should do to maximize the life of the furnace heat exchanger, and similarly, things you should not do because they are likely to destroy your furnace before its time. Here we also discuss provide typical Residential Warm Air Heating Furnace Heat Exchanger Life. Factors that Impact Residential Warm Air Heating Furnace Heat Exchanger Life.

Typical Residential Warm Air Heating Furnace Heat Exchanger LifeClick to enlarge any imageWhat is a Heat Exchanger Furnace heat exchangers transfer heat from the burning fuel typically LP gas, natural gas, or heating oil into building air. Plate heat exchangers provide highly efficient heat transfer between two liquids without allowing them to mix. They are ideal for managing coolant pressure d. Periodically, individual exchangers must then be taken out of service and cleaned, again with high impact on production and considerable health and safety. In most designs combustion gases pass from the combustion source oil or gas flame and combustion chamber through the heat exchangers interior tubing to an exhaust point that vents gases through the heaters flue and chimney sketch at left. What happens if a heat exchanger leaks If a heat exchanger develops a leak through rust perforation or by cracking due to metal fatigue the heating system is most likely unsafe and needs repair or replacement. There are two principal reasons to talk about furnace heat exchanger life 1. Safety a leaky heat exchanger can be dangerous, risking carbon monoxide poisoning. Cost although it is possible to replace a leaky heat exchanger on many furnace models not all, the labor cost and total cost investment in such a replacement in an older furnace is questionable enough that more often the ultimate cost is that of a new heating system. A while back at HEAT EXCHANGER LEAK TEST reader Marlin asked what is the normal life of natural gas furnace to which we replied Just about the warranty period manufacturers know their equipment well warranty periods run from 1. But this was a bit too glib. Here we provide the details about the causes of leaks in furnace heat exchangers and about furnace heat exchanger life expectancy. Why do we care about leaky furnace heat exchangers Furnace heat exchanger leaks may vary from trivial even below the limits of detection, potentially fatal. Watch out Dangerous carbon monoxide gas leaks CARBON MONOXIDE CO, potentially fatal. Actual risk of CO poisoning varies even when there is a leak in a furnace heat exchanger depending on where the leak is, its size, the fuel used gas vs. HEAT EXCHANGER LEAK TEST. Factors that Impact Residential Warm Air Heating Furnace Heat Exchanger Life. The top two most commonly cited causes of leaks or failures of a forced warm air furnace heat exchanger are corrosion and metal fatigue. To understand the actual causes of heat exchanger failures in a bit more detail is to know how to reduce the risk of this potentially dangerous and costly defect. Adjustment of the furnace burner oil or gas, fuel to air mixture, or combustion air defects any improper operation that causes the furnace burner to run too hot or too cool can damage the equipment in a variety of ways thermal fatigue, condensation, production of corrosive agents. Airflow restrictions anything that slows the flow of building air over the furnaces heat exchanger risks subjecting that component to high temperatures, increasing metal fatigue and shortening the units life. Examples of airflow problems include dirty air filters, crushed, damaged air ducts, even improper original duct system layout and design. Beware of more subtle dirt that slows air flow such as a dirty squirrel cage blower fan a component not normally included in furnace cleaning jobs. Wordle Download Free For Windows more. Greenheck points out that Other than a corrosive environment, the airstream temperature rise is the largest factor driving heat exchanger material selection. Equipment specifications, construction quality and materials of the furnace such as grade and thickness of steel used. Fan limit switch  operation or any event that subjects the heat exchanger to abnormally high temperatures. For example,. if the fan limit switch is modified, damaged, or improperly adjusted then the heat exchanger can be subjected to a too high operating temperature or it may be subjected to abnormally high temperatures if the blower fan shuts off too early at the end of a heating cycle. Furnace type while a multi stage furnace is probably more economical to operate, this design may subject the heat exchanger to higher temperature fluctuations. This concern may be offset by improved manufacturers warranty terms. Gas pressure in gas fired furnaces, if gas pressure is too low the furnace heat exchanger may be subjected to excessive wet time increasing corrosion in the unit. In oil fired furnaces improper burner adjustment may produce similar corrosive effects if soot combines with moisture. Heat exchanger materials some warm air heaters such as some models of Rheems gas furnaces using a stainless steel construction assert improved corrosion resistance and resistance to thermal fatigue 1. Heat exchanger materials need to resist both corrosion and the effects of temperature cycling. Commercial and indirect fired heat exchangers in some commercial equipment offer alternatives to steel aluminized steel the aluminum corrodes to form an aluminum oxide resisting further corrosion, and stainless steel chromium content resists corrosion by a mechanism similar to the aluminized steel product. As aluminized steel approaches 1. F the aluminum begins scaling, exposing. This temperature corresponds to an airstream temperature rise of. F. However, at temperatures below the aluminized steel. From this information, Greenheck recommends. F or less and stainless for. F. For heating and ventilating applications and make up. F, aluminized steel. For make up. air applications in cold climates where airstream. F, stainless steel is. Installation installation errors, even mechanical damage. Maintenance level frequency of the heating system regular cleaning maintenance extends equipment life. Oil burner soot forms corrosives when left in place in the off use season. Failure to keep the heat exchanger clean subjects it to higher temperatures, potentially damaging this key component. See. HEAT EXCHANGER CLEANING. If the furnace is capped by a cooling coil, maintenance must assure that its condensate is properly handled and the coil kept clean. See CONDENSATE LEAKSMoisture exposure of the heat exchanger to moisture and thus rust leaky humidifier, especially a humidifier or AC drip pan located above the heat exchanger humidifier or condensate leaks onto the heat exchanger, chimney leaks from condensate or actual water entry a heat exchanger in a furnace located in a wet or damp basement or crawl space is at extra risk of rust damage perforation. The heat exchanger is also exposed to extra moisture simply from condensation if the system has long off cycles during the heating season. Air Cooled Heat Exchanger Oil Cooler. Introduction.
