Concrete Floor Heating - Learn the truth about Radiant Heat

How does radiant heat work? There's two basic types of concrete floor heating hydronic and electric. The most cost effective system for medium to larger homes is hydronic since the amount of power it would take to heat a whole home with electric would be substantial.. Due to it's density and low conductivity concrete retains heat very well.

Wet Process for Manufacturing of Cement - GharPedia

The kiln has to operate continuously in order to ensure a steady regime and therefore uniformity of clinker. The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day. The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process.
