Residential Hot Water Boilers and Hydronic Technology

I.     Course Prefix/Number: AHR 206

       Course Name: Residential Hot Water Boilers and Hydronic Technology

       Credits: 3 (3 lecture; 0 lab)

II.    Prerequisite

AHR 101 and AHR 102 or consent of department chair.

III.   Course (Catalog) Description

Course covers conventional and modern residential hydronics systems. Topic focus on "Near boiler" piping, accessories and zoning operations; proper sizing of heat emitting components, baseboards and piping.

IV.   Learning Objectives

Students will learn basic hydronic systems for residential and light commercial buildings.  Condensing and non-condensing boilers, hydronic heat pumps, piping, fittings and valves, fluid flow in hydronic systems, circulating pumps, single and multi-zone systems are cov-ered in this class.  Controls and control systems are covered.  Students learn trouble shoot-ing in classroom.  During lab the students design and build a miniature heating system.

V.    Academic Integrity

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
Details of the Code of Academic Conduct can be found in the Student Handbook.
