Condensing boilers enable resort to operate more efficiently
Problem: At the JW Marriott in Tucson, Arizona, inefficient heating hot-water boilers were operating separately from the domestic hot-water system. Oversized storage tanks were contributing to additional energy losses. Both loops were operating year-round due to a requirement of hot-water reheat on the hydronic side of the system. The system was also failing to utilize current technological advancements effectively. The main goals of the project were to eliminate 6,000 gallons of stored hot water and ensure the new system could meet compliance with corporate initiatives for performance and Legionella mitigation.
