Résumé

Subsequent to space conditioning, domestic hot water is the second largest consumer of energy in American homes. Improvements have been made in the energy efficiency of water heating equipment, but few gains have occurred in the distribution system's energy performance. Energy and water waste associated with distribution system performance can be a significant fraction of the total expenditure of delivering and generating hot water. Improving hot water delivery systems will reduce the energy usage and system performance. Results from numerically simulating four different hot water distribution systems in three different system locations in a conventional house reveal that system configuration and location as well as pipe material and insulation noticeably impact the overall performance of the distribution system.
