2010-8-3 · Water quality is primarily an issue with steam boilers that use a lot of make-up water. Closed-system hot water boilers are the least effected by water quality because they use the least amount of make-up water and operate at lower temperatures. The common minerals in water that lead to scaling problems are iron, calcium, magnesium and silica.
