- Abstract
- Procedures are developed for testing and rating the performance of residential central furnaces and boilers of the condensing type. The test procedure is similar to one developed by the National Bureau of Standards for the Department of Energy covering non-condensing central heating equipment, except that it requires slightly tighter control of the laboratory temperature, a return water temperature of 120F (48.9C) with a 20 degree Fahrenheit (11.1 degree celsius) water temperature rise for hot water boilers, and offers an optional test procedure for condensing units having no off-period losses. The rating procedure provides a method for estimating the steady-state, part-load and annual fuel utilization efficiencies of condensing furnaces and boilers.
