90%+ new heater ...steam???

Hi,
I just got a new heater installed. The exhaust goes outside and up the wall of my house about 12 feet. It's 3" PVC with a 90 an elbow at the top.

I'm noticing a fair amount of steam coming out from this "chimney".

Is this normal?

This should share as a slide show:

Water/Moisture is a by product of combustion, especially in higher efficiency furnaces. On colder days, you'll see the moisture in the exhaust gas. Sorta like when you breath out on a very cold day. You can also see this in cars tail pipes in the early mornings.

Yes, it's normal.

Thanks Tom, your answer makes perfect sense. I was just surprised by how much steam was escaping; I didn't expect to see clouds!

If the humidity gets high enough and it gets cold enough..... you'll have ice and icicles hanging from the pipe.

My spidey sense tells me you are in a climate zone where you would expect steam.
I woud suggest you go back and add your location to your profile to help with any future questions.
