katlakivis

Katlakivis is a Finnish term that translates to "boiler scale" or "limescale" in English. It refers to the hard, mineral deposit that accumulates inside water-heating appliances such as boilers, kettles, and water heaters. This deposit is primarily composed of calcium carbonate and magnesium carbonate, which are naturally present in hard water.

The formation of katlakivis occurs when water is heated. As the temperature rises, the solubility of these minerals decreases, causing them to precipitate out of the water and form a solid layer on the heating surfaces. Over time, this layer can become quite thick and dense.

The presence of significant katlakivis can lead to several problems. It acts as an insulator, reducing the efficiency of the appliance. This means more energy is required to heat the water, resulting in higher energy bills. Katlakivis can also restrict water flow, potentially damaging the appliance by causing overheating or component failure. In extreme cases, it can shorten the lifespan of the equipment.

Preventing and removing katlakivis often involves treating the water supply or descaling the appliance. Water softeners can reduce the mineral content of the water before it enters the appliance. For existing scale, descaling solutions, often acidic in nature, are used to dissolve the deposits. Regular maintenance and cleaning can help mitigate the build-up of katlakivis and ensure the efficient operation of water-heating systems.
