«Lemax» boilers of the «Wise» series are made of 4 mm high-quality gray iron manufactured by VIADRUS (Czech Republic). Inhibitor treatment protects the heat exchanger from corrosion. The boiler works in closed systems with the operating pressure of 4 atm maximum. 

  • Wide model range: 16, 25, 35, 40, and 50 kW.
  • Equipped with original components of gas burner units and SIT gas valve, as well as POLIDORO injection microflame burner.
  • Used in the heating system with forced and natural coolant circulation.
  • Efficient operation with minimal ratio of the boiler water capacity to the heat exchanger’s weight and area.
  • Continuous smooth power modulation.
  • Possible connection of:
    • Indirect heating tanks;
    • Thermostats (chronothermostats) to control the boiler’s temperature relating the indoor temperature;
    • Remote home controlling systems (Android and IOS);
    • Outdoor temperature sensors;
    • External fan «Lemax» for forced rejection of exhaust gases;
    • DHW and heating system pumps.
  • Systems of protection against overheating, draft interruption and freezing.
  • Resistant to voltage variations (180 - 245 volt) and gas pressure (6 - 25 mbar).
  • LPG operation.
  • Low noise.
  • 2 years warranty.
