Drazice OKC 125 NTR Operation And Installation Manual

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 inside of the tank 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. Thermo wells 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.
