ZVB II
Compact hot water boilers ZVB II – efficient and compact heating with wood pellets
Are you looking for a reliable, environmentally friendly and highly efficient heating system? ZVB II hot water boilers are the ideal solution for radiator, underfloor or fan coil heating, whether for small spaces or medium-sized buildings.
Their robust steel construction and modern design ensure durability and aesthetic appeal, while the built-in burner with automatic ignition and turbulators with manual cleaning enable optimal combustion of wood pellets.
At the "heart" of the boiler is an advanced digital control with an intuitive 7” touch screen, which controls the operation via the flue gas fan, i.e. the flue gas temperature and the boiler water temperature. In addition to the boiler, the control can control one mixing or direct heating circuit and a sanitary water circuit with recirculation – a total of up to 3 pumps and one mixing valve.
For additional flexibility, the boilers can be expanded with additional equipment: a fuel level sensor, a larger tank with a screw conveyor for automatic replenishment, a module for additional heating circuits and room correctors or thermostats. The pellet tank is an integral part of the boiler.
With ZVB II boilers you get reliability, efficiency and control – without compromise.
-
ENVIRONMENTALLY FRIENDLY
Low emissions of harmful compounds in flue gases. -
EFFECTIVE
High boiler utilization guarantees good efficiency. -
PELLET SUPPLY
It independently supplies pellets using a screw conveyor and ignites them using an electric heater. -
EQUIPPED
Factory-installed pressure switch, flue gas temperature sensor, thermostat, fuses, safety valve, pellet supply motor and air vent.
Security elements
- Safety pressure switch: Continuously monitors the pressure in the smoke channel. If the smoke outlet is blocked or there is strong wind, it automatically stops the pellet supply to prevent potential problems.
- Flue gas temperature sensor: If the flue gas temperature becomes too high, this sensor automatically stops the stove operation to protect the system.
- Safety thermostat: Equipped with a manual reset function, it protects the boiler from overheating the water.
- Electrical fuses: Multiple fuses prevent damage in the event of problems with the electrical voltage.
- Safety valve: Provides additional protection against excessive pressure, ensuring stable operation of the boiler and heating.
- Pellet supply motor: If the gear motor stops working, the boiler continues to operate until the flame goes out due to lack of fuel, allowing controlled shutdown.
- Automatic air vent: Intelligent valve to remove air from the heating system, ensuring smooth operation and efficiency.
