The Use of Solar Energy for Heating an Asphalt Storage Tank

Report No: 85-R5

Published in 1984

About the report:

A 10,000 gal. asphalt storage tank was equipped with a solar heating system and instrumented to determine its effectiveness over a 12.5-month period. An evaluation of the data indicated that the solar system conserved 25,126 kWh of electrical power during the monitoring period. At a cost of $0.0387 per kWh, savings of $972.24 were realized. A present-value analysis of the data indicated that the investment in solar energy systems to assist in heating asphalt is a favorable alternative to the conventional electrical heating system used by the Virginia Department of Highways and Transportation.
