WASHINGTON, DC:  3501 13th St. NW is the latest address to have a solar thermal system installed.  The multi-family housing unit now has solar collectors on the roof, installed by Maryland solar contractor Solar Energy Services, Inc. to pre-heat the building’s existing conventional water heater.

The solar system includes 32 solar thermal collectors, south-facing on the building’s roof, closed-loop plumbed to 2, 806 gallon tanks.  The system is expected to significantly reduce the building’s utility bill by offsetting their water heating load with solar.

COLLEGE PARK, MD:  Earlier this week Solar Energy Services, Inc. completed the installation of two separate solar energy systems at the Cherry Hill Campground.

The solar domestic hot water system consists of 10 panels, for a total of 400 square feet of collectors integrated with four, 120 gallon solar storage tanks, each with dual heat exchangers. On the same roof, SES installed a 22-panel solar pool heating system (920 square feet) designed to heat the main swimming pool during the spring and fall, saving Cherry Hill Management a tremendous amount of energy and money.

As part of the installation, SES also replaced the existing inefficient boilers with high efficiency modulating, condensing boilers (natural gas) integrated with the solar system to provide backup energy for domestic water heating. SES also installed crossover valves to allow Cherry Hill to divert solar energy to the secondary pool when the main pool reaches desired temperatures.
