PRODUCT TECHNICAL SPECIFICATION 

1.1

 

FUNCTION DESCRIPTION 

Tank type water heater (the heater hereinafter) is designed for the accumulation heating of service

 

water by 

electric energy. Water is heated by an electric element in an enameled thermally insulated tank at the time 
defined by the power supplier. At the time of the heating, the element is controlled by thermostat on which 
the desired temperature can be set (ranging from 

0 °C

 to 

77 

°C

). Once the selected temperature is reached, 

heating  interrupts  automatically. Water  accumulated  in  the  tank  is  then  used  for  consumption.  The  tank 
keeps constant pressure of water from the water main. If the combination faucet hot water valve is opened, 
water from the water supply conduit pressed out by cold water pressure flows out of the heater. Hot water 
flows out  through the  top part, and water flowing in remains in the bottom part of the  heater. Pressure 
principle allows hot water withdrawal at any place from the heater.

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 

The heater is insulated with quality polyurethane Freon free foam. Set the temperature of the 
heater's thermostat to that level only that you need to run your home. Thus you will reduce 
electricity consumption, as well as the amount of lime sediments on the walls of the receptacle 
and on the electric body. 

1.2.3

 

EMERGENCY POWER CONSUMPTION 

According  to  current  legislation,  the  standby  consumption  is  stated  in  the  value  of  annual 
consumption of electric energy (kWh), which is measured according to the corresponding load 
profile  and  calculated  according  to  the  formulas  and  requirements  of  EU  Regulation 
No. 812/2013.
