Disclosed is a method for detecting domestic hot water use by a sanitary fitting during an observation period by analysing data relative to volumes of water passing through a water meter, the method including: receiving a first item of data, noted VΔ1, representing the maximum volume of fluid measured over a predetermined period, preferably equal to 5 minutes; receiving a second item of data, noted VΔ2, representing the maximum volume of fluid measured by the meter during another predetermined period, preferably equal to 15 minutes; and detecting that domestic hot water has been used when VΔ1>15 litres and VΔ2≥20 litres.
