Why so much steam from my modcon?

Serge

Hi All:

My contractor put a Prestige 110 with an indirect SMART tank in when we remodeled.  Hot water all the time and nice quiet heat, so I can't complain.  But...he vented it out the back side wall of the house, and it seems like it puts out a lot of steam.



Is this normal for modcons?  It does put out a bit of condensate too, so it is "condensing"....

Normal

to a point. the Flue gases are condensing.

I kinda figured it was fine....

But just wanted to check.  I mentioned it to my contractor and he just looked at me like I should know better.....

Yep.

That's normal. The lower the return water temp the more condensate you should get. The manual should give a rough estimate of about how much condensates is normal within a given temp and time frame. Viess.
