FIELD: water supply systems.
SUBSTANCE: invention relates to method of preparing a drink by feeding hot water into hot-drink proportioner with the help of fluid transfer circuit incorporating a heater. Aforesaid heater comprises thermal resistor and pump. With the device switched on, fluid gets heated on feeding preset mean electric power to thermal resistor for it to keep on heating circulating fluid at constant rated flow rate of 0.5-1.5 centiliter/s. Note that mean electric power of thermal resistor makes the value in watts that its ratio to rated flow rate in centiliter per second exceeds 2000.
EFFECT: time savings.
