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 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.
If hard water is used in the boiler, it will form scale on the inner wall of the boiler, which will hinder the heat transfer of the pipeline, consume more fuel and shorten the service life of the boiler. Moreover, due to local uneven heating, even if the temperature is too high, the boiler may explode. 406 views.
Can Hard Water Affect My Boiler? | ACI North West Blog
Hard water is water that has a high mineral content (water with a low mineral content is known as soft water). This content usually consists of high levels of metal ions, mainly calcium (Ca) and magnesium (Mg) in the form of carbonates, but may include several other metals as well as bicarbonates and sulfates. Hard water has minerals which will coat the inside of boiler tubes for water tube boilers and the outside of tubes for fire tube boilers.
Another reason to monitor water usage is that high water usage will hasten scaling when the water has a high mineral concentration (hard water). It's useful to note that the level of water hardness varies throughout the United States and Canada, and depending on a boiler's location, high water usage has been known to result in scaling within a matter of weeks (see graph below).
Jan 18, 2016 · While hard water may not be harmful to you directly, it can cause a number of problems with your plumbing system and appliances using water, including your boiler. The minerals in the hard water can lead to scale building up within your boiler. You may notice that you hear a rumbling sound coming from your boiler.
