The problem of limescale in hydraulic devices that produce or use hot water is a well-known phenomenon in everyday life. It is common in the following appliances: electric water heater, washing machine, dishwasher, coffee maker, electric kettle, etc. To overcome this problem, several approaches exist and can be applied to the different levels of the hot water production system. This work enables to characterize the drinking water of some regions in Morocco, looks for conditions that minimize lime scale production and shows experimentally that this latter has a significant effect on the energy bill of a building. The results show that it is preferable to introduce a water filtering system (softener), especially in areas where water is hard or very hard. This will be applied to the building's water supply to reduce the energy bill, extend the life of hydraulic installations, reduce the frequency of maintenance, make soap and detergents more efficient and also improve the quality of drinking water.
