ZVB II

Compact hot water boilers ZVB II are intended for burning with wood pellets. They are intended for hot water heating (radiator, floor, fan coil…) from the smallest to medium-sized buildings. They are of steel construction, modern design and high efficiency. The boilers are equipped with a burner for burning wood pellets with an automatic ignition function and turbulators with manual cleaning. The digital boiler regulation with a 7″ touch-sensitive screen controls the operation of the boiler via the flue gas fan controlled by the smoke and boiler water temperatures. The boiler regulation, in addition to the boiler, can control one mixing or direct heating circuit and one sanitary water circuit with recirculation, i.e. a maximum of 3 pumps and one mixing valve. It is possible to order a fuel level sensor, an additional larger tank with a conveyor belt that automatically replenishes the tank in the boiler, a module for additional heating circuits and room correctors or thermostats.

PRODUCT CHARACTERISTICS

  • SUITABLE FOR THE ENVIRONMENT

    Low emissions of harmful compounds in flue gases.

  • EFFECTIVE

    High efficiency of the boiler guarantees good efficiency.

  • DELIVERY OF PELLETS

    It supplies pellets independently using a screw conveyor and ignites them using an electric heater.

  • EQUIPPED

    Factory installed pressure switch, flue gas temperature sensor, safety thermostat, electrical safety, safety valve, reduction motor and automatic vent valve.

BASIC DIMENSIONS

SAFETY DEVICES

  • Pressure switch: It controls the pressure in the smoke duct. It blocks the pellet transporter in case the drain is blocked or there are significant counter pressions.
  • Flue gas temperature sensor: This sensor is located on the upper part of the fan and if the flue gas temperature is too high, it will stop the operation of the boiler.
  • Safety thermostat: Safety thermostat with manual reset for the water temperature.
  • Electrical safety: The Boiler is protected against violent surges of current (ex. lightnings) by the main fuse which is located on the control panel at the rear of the boiler.
  • Safety valve: This valve acts to prevent over pressurization of the hydraulic system.
  • Reduction motor: If the motor stops, the boiler continues to function until the flame goes out for lack of fuel, and until It has cooled down to the minimum level.
  • Automatic vent valve: This valve eliminates the air inside the boiler and of the heating system.

TOUCH SENSITIVE SCREEN:

  • It enables direct interaction with the content displayed on the screen.
  • Simple management of boiler operation.
