Me, well, I block all posts from the Sucko Company. I
wouldn't believe anything there.

The problem with high efficiency heaters, is that the flue
gasses aren't hot enough to carry up the conventional
chimney. So, they add an inducer fan. The condensing comes,
because they are able to cool the flue gas enough to
condense much of the water vapor. That resulting liquid
condensate has to be drained some where. Sometimes outdoors,
and sometimes into a sanitary sewer.
