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.
1.2.2
ENERGY SAVING
If you use electronic thermostat in the mode which enables manual setting of the required
temperature, set it only for the value which you need for the household operation. Thus
you will reduce electricity consumption, as well as the amount of lime sediments on the
walls of the receptacle and on the electric element's pit. Manufacturer recommended
temperature for the lowest possible heat loss is 55°C. Higher saving of electricity requires
one of the intelligent operating modes - SMART or PROG (more information on the
operating modes is in chapter „3 thermostat operation“).
1.2.3
EMERGENCY POWER CONSUMPTION
If no heated water is taken from the tank, a small amount of heat leaks. This loss is
measured for a period of 24 hours at the temperature of 65°C in the heater, and at 20°C in
its ambient area. The resulting value is expressed in units [kWh/24h] and indicates the
amount of power needed to maintain the set temperature.
