FAQ: How Are Water Softeners Used in Steam Boilers?

One of the most important accessories you can have for your steam boiler is a water softener. At first, you may not think of it as an unnecessary add-on for an already expensive boiler. But a water softener actually serves several purposes and can play a crucial role in helping your boiler avoid malfunctions and run more efficiently.

Hard water that’s filled with minerals like calcium and magnesium can cause damage to the tubes inside steam boilers. If these minerals are present in the boiler’s water supply, it can lead to hard scale forming on the surface of the tubes, which has the potential to cause the water to overheat and ultimately the tubes to fail.

The efficiency of a boiler can also be negatively affected by hard water. If the presence of calcium and magnesium causes hard scaling, it will have an impact on the heat transfer inside the boiler. A layer of hard scaling as small as 1/8 of an inch on boiler tubes can decrease efficiency as much as 25 percent. This will only make the boiler work harder and consume more fuel in order to meet your steam needs.

The solution to both of these potential problems is a water softener working in conjunction with your boiler. Water softeners will introduce sodium compounds into the boiler’s water supply to negate the presence of any calcium and magnesium, effectively resolving the hard water problem. A water softener will reduce the risk of hard scaling inside the boiler, improve the flow of water, ensure maximum levels of efficiency, and help your boiler avoid failures or any kind of damage that could reduce its lifespan.

A Miura water softener can be integrated with a boiler’s control panel and monitoring system. A hardness detection system can also be installed to automatically test the hardness of the boiler’s water supply. If necessary, the water softener will be activated to inject sodium compounds into the water in order to balance out the hardness. This is the easiest way to identify that hard water is a problem and address the problem.
