This article lists significant Oil-Fired Heating boiler (hot water or hydronic heat) defects, definitions, and home inspection education topics. This article series, beginning at BUILDING DEFECTS LISTS, provides lists of common building defects and basic defect knowledge that also outline recommended curriculum content for home inspector education. The building defects and inspection points listed in these articles also guide homeowners and home buyers to building areas that merit careful attention and often point areas of safety concern or important maintenance and repair tasks. Readers should see HEATING SYSTEMS for our complete list of articles on this topic. Also see HOME & BUILDING INSPECTORS & INSPECTION METHODS. Use the Search Box at the top or bottom of these pages to find in-depth information about building, energy savings, and indoor environment inspection, diagnosis and repair at this website. Watch out: these inspection lists do not list all possible defects for the systems discussed, and not all home or building inspectors will examine all of the items listed here. CONTACT us to suggest corrections or additions to articles at this website. Also see BOILERS, HEATING, BOILER NOISE SMOKE ODORS, BOILER OPERATING PROBLEMS These curriculae and building defect lists are based on smilar curriculum documents first prepared by Joe Scaduto, an ASHI member who prepared course material for Northeastern University's Building Inspection Certificate program in 1988, subsequently by DF, InspectApedia's editor, for New York University ca 1988 and later, with others, recommended to ASHI, the American Society of Home Inspectors. ASHI did not adopt this material though currently that association as well as others offer extensive HOME INSPECTOR EDUCATION material. The curriculum and lists of defects are informed by additional analysis of the process of home inspection that was developed beginning Calgary, AB for Canadian and U.S. home inspector education and certification examinations in 1997. Other early contributors to home inspection education in the U.S. and Canada include Dr. Jess Aronstein, Alan Carson, Mike Casey, Mark Cramer, John Cox, Dwight Barnett, Douglas Hansen, Rick Heyl, Larry Hoytt, Bill Merrill, Kevin O'Malley, Dennis Robitalille, Keith Peddie, Pat Porzio, Roger Robinson. © Copyright 2012 InspectAPedia.com, All Rights Reserved.

Home Inspection Education Curriculum - Heating Boiler Defects4.3 Hot Water Heating Boilers - Hydronic Heating System Defects List4.3.1 Knowledge Base for Oil Fired Heating Boilers1. Describe the function of a hot water (hydronic) heating system. 2. Describe open and closed heating systems. 3. Describe four types of distribution piping (series loop, 1-pipe system, 2-pipe system - direct return, 2-pipe system - reverse return). 4. List the materials and components of a typical hot water heating system including fuel storage and supply system, burner, combustion air supply, venting, cabinet/body, heat exchanger, controls, expansion tank, pump (circulators), pipe, radiator, convector, baseboard, radiant heating. 5. Describe the features of adequate installation and repair technique for hot water heating systems. 6. Outline the advantages and disadvantages of hot watering heating relative to forced air heating. 7. Outline the differences between boilers and furnaces, including the normal operating cycles. 8. Define the following terms with respect to hot water boilers: convection, conduction, radiation, super heated water, pressure relief valve, high temperature limit switch, low water cut-out, backflow preventer, pressure reducing valve (automatic water makeup), automatic air vent, primary control pump(circulator), zone control, outdoor air thermostat, flow control valve, isolating valve, tankless coil, radiator bleed valve, radiator control valve, air separator (air scoop), aquastat, open expansion tank, closed expansion tank, diaphragm (bladder) expansion tank, side arm heater, indirect water heater, mixing valve(tempering valve), condensing boilers. 9. Outline the life expectancies of boilers made of various materials. 10. Identify the codes or standards which apply to hot water heating systems in your area. 4.3.2 Inspection Skills for Oil Fired Heating Boilers1. Describe the inspection procedure for hot water heating systems. 2. Identify the following common defects listed on the next page. 3. Describe the implication of each defect. 4. Identify safety issues for the inspector and occupant of the home (steam explosion, combustion product poisoning, electric shock, physical injury). 5. Communicate findings to client verbally and in writing, recommending corrective action where needed.
