Combustion Appliance Zone
I saw your recent article on combustion safety (“Combustion Appliance Testing: Why, How, When?” Nov/Dec ’10, p. 38). I think I have a problem and was wondering if you would give any suggestion. I have a ranch-style home. In the basement, my furnace and water heater shared the same exhaust. A direct-vent furnace was installed, and a 4-inch liner for the orphaned water heater. If a dryer, two bathroom fans, and one kitchen fan are turned on, the combustion appliance zone (CAZ) is at about -8 Pa. The BPI guy who had checked on the house suggested a power-vented water heater or that I remove all the fans from the house. Unfortunately, the water heater is only three years old. What else can I try to correct the problem?
Cheating Not Such a Secret Anymore
Great article: “Cheating—The Insulation Industry’s Dirty Secret” (Nov/Dec ’00, p. 24) by Michael Uniacke. I have been involved in the building industry for over 30 years. There is no question that the insulation contractors and installers have gotten and are getting away with murder.
Many inspectors believe, “If it’s not a safety issue, it’s not my problem.” However, times are changing and building departments are now finding that they are accountable for enforcement of the energy codes. We all need to make sure the customers are getting what they are paying for. Our collective efforts will save millions of dollars in energy costs if we work together and do our jobs.
