Note

Installers should inquire of local water purveyors as to the suitability of their supply for use in

hydronic heating systems.

If water quality is questionable, a local water treatment expert must be consulted for testing,

assessment and, if required, treatment.

Alternatively, water or hydronic fluid of known quality can be brought to the site.
