Patent ID: 8503870

Claim:
A method for preparation of a drink by supplying hot water through a liquid transport circuit ( 2 ) comprising: a heating element ( 8 ) provided with a heating resistance ( 12 ); a pump ( 14 ) arranged in series with the heating element ( 8 ) and adapted to circulate the liquid in the circuit ( 2 ); the method further comprising after a user actuates a control means ( 7 ): the liquid is heated by supplying a predefined average electrical power to the heating resistance, and a temperature (T) of the heated liquid is measured; the liquid is kept heated; and when the measured temperature (T) is greater than a first predetermined temperature threshold (T 1 ), the liquid for the drink is circulated in said heating element ( 8 ) with a given constant nominal flow (D), characterised in that said given constant nominal flow (D) is less than 2 cl/second, when the average electrical power of the heating resistance ( 12 ) is a ratio (R) that is the average electrical power expressed in Watts divided by the constant nominal flow expressed in centiliters per second, where in the ratio is more than 2000.
