High efficiency furnace - water out of outside pipe
 

Hi,

I recently had High Efficiency furnace installed (Carrier Infinity) and
there were 2 PVC pipes put outside my house - one is for taking air into
furnace and another one for air out of furnace. When furnace is working, my
second pipe is spraying water out of it - not a lot, but still hand feels
wet if you hold up to it. It seems kind of strange. Is that a good furnace
installation? Should it be like that? If yes, then would it not freeze in
the winter?

Thanks

I know at times that the vent pipe does show some signs of water droplets
near the end of the pipe. I take this to mean that not all of the moisture
has been removed from the exhaust air of the furnace and as such condenses
near the end of the pipe. As far was water spraying, haven't seen that. Is
your condensate pump system working because that is where all the moisture
should end up. BTW, look at the way the pipes are installed, they should be
in a slight angle up towards the outside.

Our high-efficiency furnace develops an icicle stalagmite below the
exhaust pipe in winter. We have to knock it down around February to
prevent it from enveloping the pipe.

This is Turtle.

The vapor being very moist is normal and is working fine. These vapors was at
2,000ºF when it was in the furnace but the furnace takes so much of the heat out
of the vapors that it makes water drop out of the vapors and will be sometimes
at about 80ºF or so.

Now i have rarely ever seen the vapor close off the pipe but have seen a good
amount of ice from where they drip off the end of the pipe.

Dang Turtle, didn't know it got that cold down there in your area....;-).
Yeah, the furnace seems to be fine. What you are seeing and/or feeling is
normal as Turtle said.

Some water vapor is normal, you say spraying water though. Im sure
Carrier can tell you how much is normal, an improperly angled exhaust
is possible as is maybe [ Im guessing ] improper furnace angle for
draining. My PVC exhaust does not freeze at - 20f and properly
instaled they should rarely freeze. Im sure they are used where it gets
to -60F. Water vapor is normal as 93% of the heat is removed and NG
contains allot of water. That is why you cannot vent HE furnaces
through an unlined chimney, water and acid will eat brick. If you
really drip water it may be of concern. Check the level of the exhaust
and call Carrier to see what they recommend and how to check things
out. Your furnace drains water from combustion, check that also.

Yea, We have a weather forcaster that has stated that we may get some ice in the
water in the ditches along side the roads by Jan. or Feb.. It has been laterly
getting in the 80's and 90's during the day and 70's at nite. Everybody will
crank up there heating furnaces to see if the work a little before Christmas
before the winter sets in. I try to get all my customers to do this at Thank
Giving to be a head of the game.
