Hydronic
Hydronic refers to a method of heating and cooling buildings using water or other liquids as the heat transfer medium. It's like a building's circulatory system, where warm or cool water flows through pipes to heat or cool spaces. This includes systems like radiant floor heating, baseboard heaters, and chilled beams. When you see this term in resumes, it usually means the person has experience working with water-based heating and cooling systems, which are known for being more efficient and comfortable than traditional forced-air systems.
