Oil Furnace Lifespan

camiarrobino

Hello all -
Seeing if anyone has any direct experience / opinions on life expectancy of the type of oil warm air furnace that I have. It's a Williamson low-boy style CLB-105-DD-F-S2. I believe year of manufacture 2012 or 2013, with an 86% efficient burner (I think Beckett)
I know that the rule of thumb for furnaces is about 30 years, but this just seems very general / back of the envelope to me. Just curious if there's anything in particular about oil furnaces in general (compared to gas / propane) and specifically the kind that I have that contributes either way to life expectancy. Someone told me that oil furnaces CAN last longer due to much beefier components than gas / propane, but not sure how true this is

20 years plus with a furnace you got your moneys worth . A Low Boy furnace , I would expect a extra 10...

A Thermal Pride furnace another 10 after that...

The biggest killer of furnaces, particularly oil is lack of airflow through (around of course) the heat exchanger, exceeding manufacturers recommended temperature rise.
Also not properly cleaning.

mind explaining to the lay-man what about a low-boy would extend it's life?

I'm not sure why a low boy furnace would last longer either. As Steve said airflow is key. The ductwork needs to be able to move enough air through the furnace to prevent over heating the furnace and short cycling.  Proper installation and maintenance are critical to long lifespan. 

Thermopride makes the best furnaces. I work on plenty that are over 30 years old.

I would have to say the design of the low boy gives better air flow around the heat exchanger .
