 +=== Recomendations / Best Practice ===
 +
 +Recommended operations temperature 
 +
 +  * Minimum 50 °C
 +  * Preferred 55 °C
 +  * At most 60 °C
 +
 +And at least a minimum of 50 °C in the entire pipe system.
 +
 +=== Water heater ===
 +
 +With a water heater you should raise the temperature to above 65 °C for 10 minutes weekly, and keep the temperature at 
 +
 +=== Water heater with circulation ==
 +
 +With a water heater with circulation you should raise the temperature to above 65 °C measured in return temperature.
 +
 +=== Cold water ===
 +
 +At most 20 °C but recommended below 10 °C
