Dialogue sur Nespresso en anglais

Henoc : Today I going to talk manual espresso machine ecp 3420. Indeed, we will first talk about the features. Then, we will talk about the operation of the coffee machine, how much watt hour uses a coffee and to finish we will compare this machine to another and we will conclude .

Elias : The weight of a coffee machine is 4 kg, the maximum cup height is between 9 and 13 cm, the matérial is stainless steel, the water tank has a capacity of 1L, the pression is 15 bars and the input power is 1100 W.

Henoc : Now, we will talk about the operation of the coffee machine. At first, the water goes into the water tank and then it goes into the filter. Through the priming pump and safety valve, it goes through the solenoid then through the boiler. All that goes into the coffee storage and it flows into the cup.

Henoc : Here we can see that with the conversion the electric energy of the house for example and the water preheated by an electrical resistance, this will be filtered in the coffee maker and we will have a coffee.

Elias : To find how many Watt Hours that uses a coffee machine, we will have to multiply the power and the time. Knowing that the time to make a coffee is 17 seconds, that means 0.0047 hours, and that the power is 1100W. So 0.0047 by 1100 equals 5.17. Then , Espresso machine uses 5,17 WH for one coffee.

Elias : Now, we are going to compare the espresso machine with a coffee machine Phillips standard.

The Espresso machine consumes 1100 W while the machine Phillips uses 1450W. The Espresso machine is made of stainless steel while the Phillips one is made of steel and plastic.The capacity of the water tank is 1L for both machines .

Henoc : The pressure of the espresso machine is 15 bar whereas for the machine phillips is 1 bar. The maximum height of the cup is about 9 to 13 cm whereas for the machine Phillips it is 10 cm.The time for one coffee espresso is 17 sec whereas one coffee Phillips is 30 sec.

Elias : To conclude the espresso machine is more efficient and uses less energy than a common coffee machine.
