Dec 31, 2009· I have a question about thermal shock in hot water boilers. First is a picture of how the hot water heating system was converted and setup during the early seventies. The house was originally heated with a coal boiler that would gravity feed through an open hot water system. The system has large iron radiators, one for each room.

Dec 08, 2008· Preventing boiler thermal shock. I am in the process of designing a baseboard heating system with an indirect WH. I am using a burnham 2B (cast iron)boiler and a superstor ultra indirect. I am planning a primary/secondary piping system. My problem is that the boiler room does not have space for the indirect so it is separated by 30 ft of 1" copper.

Thermal Shock - an overview | ScienceDirect Topi

Heat or thermal shock is the main reason for fabric shrinkage. It occurs when certain material is exposed to a sudden and rapid change in temperature. It causes structural stress, and irreversibly, it changes the properties of the material. To avoid fabric damage, the heating temperature has to be raised gradually extending material heating time.
