Calorifier - Hot-water boilers
| ||Drinking water is heated and stored in hot-water boilers which are normally connected to the central heating system or using a calorifier, where an electrical coil is used to produce the heat. These boilers tend to scale up very significantly if the water is hard, primarily if the temperature is high. Frequently, such boilers also start to rust after a few years and this is why stainless steel boilers are used to a greater extent today. Pursanova TM clears the scale in the boilers if used properly, and this scale is then flushed out with the water. Existing rust deposits are partially dissolved and converted. At boilers heated electrically, there might be a problem of less efficiency if the coil gives a strong electrical field.|
