Proper Boiler Feed Water Temperature Management | Powerhouse

It is common to design a hot-water heating system for a temperature drop of 20oC (36 oF) in heating elements and radiators at what is considered as minimum outside design temperatures. Maximum boiler flow temperature is often set to 80oC (176oF) to avoid "burned dust" and accidentally injures on people when touching heaters.
