DESIGN AND GENERAL HEATER DIMENSIONS
The receptacles of the heater tank are made of steel plate and tested by 1.5 MPa multiple of operation
pressure value.
The inside of the receptacle is
enamelled.
In the bottom part of the tank there are wells
for placing the heating, regulation and safety element of the water heater (heating element with right thread
G 5/4“, thermostat sensor and thermal fuses). A thermometer is installed in the top part of the heater that
transmits information on heating the volume of service water. The receptacle of the heater is provided with
a quality polyurethane insulation that ensures minimum heat losses.
Wiring is installed in the bottom part of the heater. Water temperature may be set by a thermostat
in the range from 5 °C to 74 °C. Cold water inlet is marked with a blue circle, hot water is marked with a red
circle. All other steel parts are protected against corrosion by paint and galvanic coating. To ensure protection
against corrosion there is an anode rod installed in the head of the heating element that dissolves during the
operation of the heater and must be replaced after 2 to 3 years of service (depending on the chemical
composition of water).
