What is a condensate sump
Condensate reservoir is a space in the chimney vents, which serves to drain the condensate out of the chimney. Condensate is normally produced by gas heating but can also arise due to atmospheric humidity. The basins should be installed in both the basic types of chimney, both dry and wet. In the chimney, it can hold moisture, even if only solid fuels are used for the heating. It is definitely a financially more acceptable solution than once in a while to pay the chimneys for the repair of the humid chimney.
