So, how can you get water to leak out of a hot air furnace? Did I
miss something here?

.
: I have an oil/hot air furnace. I have a service agreement with
my local oil company where they cover
: very minor repairs. Well, the repairman diagnosed a water leak
coming from my heating coil. He
: mentioned that I can probably get it replaced cheaper from a
local plumber or even DIY.
:
: However, I called my local plumbing supply store and they said
that chaning a heating coil for an
: oil burner is not a DIY project?
:
: I only have basic plumbing and electric skills. I can weld
copper pipes on my pool heater and can
: replace PVC plumbing.
:
: Are there any generic instructions for changing the heating
coil, so I can see what I am getting
: into. If this is not a DIY project can you please let me know?
:
: The oil furnace is made by Weil-McLain and the heating coil is
encolsed in a metal conainer that is
: 22 inches wide and 17 inche depth.
:
: Thanks much,

During combustion certain gases form. In high efficiency furnaces, the
burnt gases are routed through a coil, usually stainless steel, that is
mounted to the heat exchanger by a small purge blower. Most of the heat
is extracted from those gases and condensation forms in the coil, which
is usually drained out through a hose or pipe, into a floor drain.
If the coil develops a leak, the condensation leaves the coil through
that breach in the coil instead of being drained out the tube. If water
can escape then so can the cooled combustion gases. Carbon monoxide is
one of those gases. It can make you ill or even kill you in your sleep.
This is as technical as I need to get. If anyone has anything to add,
please do.
Oh, I have 23 1/2 years experience in the hvac field.
