2013-2-13 · As steam is produced, dissolved salts remain in the boiler and continue to concentrate. Some salts may be soluble in the bulk boiler water. However, the boiler water immediately at the tube surface is considerably hotter than the bulk boiler water. As steam bubbles form near the tube wall, the soluble salts remain with the boiler water.

What You Need to Know About Residential Steam

The steam boiler is an old convection heating technology dating back over 200 years and is commonly found in older homes. Because steam boilers operate at a higher temperature than hot water boilers they are inherently less efficient than their hot water cousins.
