    Who should study this unit?

    The module is primarily intended for junior to intermediate engineers who are being asked to design a heating system for the first time.  However, the module is not for the complete beginner.  There's an assumption from the outset that the user will have completed a college or university course on mechanical engineering, or possibly a course on building services engineering, and so will have some understanding of the basic fluid dynamic principles that underlie system design.  They will also have access to the support of a more senior engineer within their organisation who can guide them on the procedures and protocols for completing design drawings and specification documents.
