This paper describes the technique that solar designers and operators can use to predict scaling on heat-transfer surfaces. Water samples collected from five Department of Energy-sponsored solar-energy systems as well as water samples of varing degrees of hardness were assessed for chemical scale forming tendencies. Collector surfaces are the most likely area for scale formation and the deposits are most likely to be calcium carbonate. Calcium carbonate scaling prediction methods and recommended water treatments are discussed.
