Just as cell phones represent a leap in technology compared to rotary dial landlines, modern panel radiators have evolved far beyond what many people think of when they hear the word “radiator.” The series of webinars will show how modern panel radiators can be integrated into contemporary projects such as net zero homes, or buildings supplied by renewable energy heat sources. They will presents simple, scaleable, and repeatable design concepts that allow these modern heat emitters to deliver unsurpassed comfort and energy efficiency in both new and retrofit applications.
