+===== Hot water =====
+The daily consumption per capita is considered to be a constant value: 50 liters of hot water [l/day/cap] (equivalent to one shower [[#Sources|[1]]]). Then the net energy demand for hot water production is calculated by setting a temperature increase of 40°C (i.e. considering a hot water supply temperature of 50°C).
+The 2011 consumption is reported to be 31.7 PJ ([[#Sources|[2]]]). This corresponds to an efficiency of 75-80%. This efficiency takes into account the losses in the boiler and in all the piping system.
+For the 2050 and 2035 scenarios, the efficiency will depend on the selection that the user has done in the submodel "Heating and Cogeneration".
