20, 25, 30, 40, 50, 70, 90, 110, 250, 450

Product features:

• Electronic the control unit controls the combustion by modulating the speed of rotation fan. Additional controlled circulation pumps Central heating and domestic hot water (DHW).
• The air supply fan optimizes combustion and
  fuel consumption.
• Simple installation and easy maintenance.
• Water shirt (heat Exchanger) is covered by a combustion chamber in full, to utilize the emitted heat most efficiently.
• The camera of combustion of the large heat exchange surface and low chamber resistance.
• Large and convenient access door of the combustion chamber facilitates
  loading solid fuel (length of wood up to 50 cm).
• The ribbed surface of the combustion chamber and a three-way path of the flue gas improves the heat transfer.
• Removable metal grate protects the pipe grid from the flame.
• Flange on lower door for fitting pellet,
  oil or gas burner (optional)

Protective devices:

• Thermostatic traction controller;
• Safety valve 3 bar.
• The device from the boiling of the boiler (safety
  heat exchanger) installed in the upper part of the boiler. In the case of overheating, opens the valve with the thermostatic valve to reduce the temperature inside the boiler.
• The discharge valve.
