Function description: 

 
The  heater  is  designed  for  accumulation  heating  of  service  water  using  electricity.  Water  is  heated  by  an  electric 
element in an enamelled thermally insulated tank at the time defined by the power supplier. The element is at the time 
of heating controlled by a thermostat the temperature of which can be adjusted continuously (within the range between 
5°C and 74°C). Once the selected temperature is reached, heating interrupts automatically. Water accumulated in the 
tank is then used for consumption. 

 

1.1

 

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.
