1.2.2 ENERGY SAVING
Hot utility water reservoir is insulated by means of top-quality polyurethane foam with zero
CFCs content. Adjust 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 heat exchanger.
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.

1.3 DESIGN AND GENERAL HEATER DIMENSIONS
The heater tank is made of a steel plate and tested by 0.9 MPa overpressure. The heat exchanger is tested
with a pressure of 1.5 MPa. The inside of the receptacle is enamelled. A flange is welded onto the bottom of
the tank with a flange lid screwed to it. A sealing ring is inserted between the flange lid and the flange.
Thermowells for placing a heating element and sensors of regulation thermostat and safety fuse are located
in the flange lid. An anode rod is mounted onto the M8 nut. The water reservoir is insulated by means of
polyurethane foam. Electric wiring is placed underneath the plastic removable cover. The temperature of
water can be set using the thermostat. In combined versions, a heat exchanger is welded in the pressure tank.
The heat exchanger is only intended for the heating circuit. Heater types OKCV 200 are produced in the right
and left design.
