Water forms in the air duct after ignition in a heating furnace without the blower running?
Thread Content
Why does water form in the blower duct over time when a heating furnace is ignited without the blower running?
Since oxygen is required for combustion in the furnace after ignition without the blower in operation, air enters through the blower outlet; coupled with high air humidity, condensate water forms on the walls of the air ducts.
Really? Why doesn’t air condense into water outside, but it does condense inside the air ducts? Is the temperature lower there? It doesn’t make sense; I don’t quite understand it
It’s hard to explain. Unless there is water accumulation in the blower duct during shutdown (due to leaks).
