CASE STUDY

Saint Andrew Life Center Gets an Update to their Water Heaters After Seven Decades of Use

After receiving two state-of-the-art Type “B” Patterson Water Heaters in 1949, the Saint Andrew Life Center facility in Niles, Illinois, experienced decades of reliable water heat. Over 70 years later, the site elected to refurbish its heat exchanger in order to restore it to peak performance. With some help from the Patterson-Kelley aftermarket team, the water heater is now running more efficiently than ever before!
