Suspended, vertical

Character

Operating position – vertical

  • Indirect enamelled heater designed for suspension on the wall with volumes between 80–200 litres. The heater doesn't have electric heating.
  • The heater is connected to the external hot water source with the maximum temperature of 110 °C and pressure of 1 MPa . Heating is assured by a high performance spiral heat exchanger. The heater is equipped with the system of hot service water temperature regulation (thermostat controlling the three-way valve or circulation pump) for the voltage 230 V/50 Hz, safety valve and circulation outlet.

Most common use

  • All-year heating of hot utility water using heating water from the gas boiler.
