Page 6: Advice For Customers
ADVICE FOR CUSTOMERS 1.2.1 HOT WATER CONSUMPTION Consumption of hot water in households depends on the number of people, amount of sanitary equipment, length, diameter and insulation of piping in the flat, or on individual habits of users. The cheapest option of water heating comes at the time when the electricity rate is reduced. Find out in what time intervals your electricity supplier provides reduced tariff and, depending on that information, select relevant volume and power input of the heater so that your hot water consumption covered the needs of your household. - Page 7 OKHE 100 - OKHE 125 - OKHE 160 - SMART SMART SMART VOLUME MAX OPERATING OVERPRESSURE IN THE TANK ELECTRICAL CONNECTION 1/N/PE ~ 230V/50 Hz RECOMMENDED BREAKER 16 A INPUT 2200 EL.
