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.
Unless this particular coil is made w/ compression or other threaded
fittings, I'd agree your skill set/level doesn't sound up to the
task...sounds like a job for the pro.- Hide quoted text -

A water heating coil on a hot air furnace? Does this exist? If it
does, I've never seen one.

The "water leak" is most likely condensation from the coil, which means
he is most probably leaking combustion byproducts, ie carbon monoxide,
into the house also. You would need to tear the entire furnace down to
get to the heat exchanger coil. Some coils are fastened to the heat
exchanger with screws. There is most likely a seal you would need to
replace also.
Leave it to a competent hvac contractor as you could poison your family
with carbon monoxide if you don't do it to the letter.
