Earlier this year, the East Hartford (Conn.) School Department expressed concern to Manchester, Conn.-based Action Air Systems about the inefficient and temperamental hydronic heating system at Barnes Elementary School.
The system was more than 50 years old and consisted of the original pipework as well as newer building improvements. In addition, chemicals had loosened up the scale on the inside of the pipes and there was not an effective method of extraction put in place for the system, which struggled to effectively work.
