United Energy Products was proud to do our part for the renovation and an addition on the existing Bird House building at the National Zoological Park in DC. Originally built in the 1930’s, this renovation readies the facility for another century of service. We worked with regional contractors to get the job done; Denver-Elek Inc. installed the Fulton boilers and Metro Test & Balance, Inc. installed the Schebler flue and ENERVEX fan system to complete the heating system.
