Published / Updated:

To compare the performance of different types of solar and conventional water heaters, a test facility was constructed at the Florida Solar Energy Center (FSEC) in Cocoa, FL. The facility tested seven systems simultaneously in a side-by side configuration.

The objective of the water heating systems evaluation project is to compare energy performance and time-of-day electric loads by conducting side-by-side tests of solar and conventional domestic hot water (DHW) systems.

Download this document to examine the comparative performance of the following seven different types of residential water heating systems:

  • Standard electric resistance 50-gallon tank
  • Solar flat plate collector (40 ft2) connected to an 80-gallon storage tank with temperature differential controlled pump – direct loop circulation
  • Integrated Collector System (ICS, 32 ft2) connected to a standard 50-gallon water heater
  • Solar Flat Plate collector (40 ft2) connected to an 80-gallon storage tank with
    photovoltaic pump – direct loop circulation
  • Standard residential 40-gallon natural gas water heater tank (storage upright vented type)
  • Natural Gas tankless water heater
  • Electric tankless water heater
