The terms “hard water” and “soft water” are ones that people use pretty often without really understanding what they mean. This can lead to a lot of people wondering what the difference is between the two and feeling worried that there could be future maintenance issues relating to their heating systems with one or the other. The difference between the two is actually very simple and straightforward. The hardness of water is measured by the levels of certain minerals contained within it. There are certain things that you may notice if you have particularly hard or soft water in your home particularly with hard water and your heating system.
The most significant factors in whether or not water is “hard” are the levels of calcium and magnesium that it contains. With hard water in your heating system, there can be a significant build-up of limescale which is created as the water heats up and cools down. As limescale builds up over time, it can cause blockages in the pipework throughout your home. This can eventually lead to a boiler breakdown. If this is causing problems for you, there are water softening systems that are designed to filter out these minerals from the water.
Unlike hard water, soft water tends to have higher concentrations of sodium in it. This means that using soft water will result in a smoother operating heating system.
