      • Description
      Description
      • Produced using European components of the following suppliers: SIT, OTMA, WILO, POLIDORO, Valmex, NordGas.
      • Ideally suited for installing both in apartments and houses with a stationary chimney.
      • Efficiency output is up to 92,5%.
      • Adapted to gas pressure loss.
      • Independent heat exchanger of the hot water circuit minimizes the cost of annual maintenance, provides temperature stability in the DHW circuit and has a longer service life compared to a bi-thermal heat exchanger.
      • A high unification level of parts and components for the entire line of Lemax wall-mounted.
      • Implemented control function through iOS and Android via the OpenTherm Protocol allows the remote control for home or an apartment.
      • Increased combustion chamber volume ensures complete gas combustion and extends the operating lifetime of a heat exchanger.
      • A built-in pressure sensor and a blow-off valve provide dual protection against heating circuit overpressure.
      • Operating in high hydraulic resistance systems avoids installing an additional pump in most cases.
      • Structurally protected sensors against corrosion and boiler scale.
      • Extended range of boiler operating voltage ensures stable operation in power grids with high and low voltage (186 - 245 v).
      • Integrated ignition transformer ensures stable spark generation and maximum smoothness of the ignition.
      • Water pressure indicator displayed on the LCD provides comfort of monitoring water pressure.
      • Reed flow sensor: the sealed contact detects water flowing without regular maintenance and provides start-up of hot water circuit when the water flow is 2 l/min, its shutoff at 1.5 l/min, and provides using the DHW circuit with low water pressure.
      • A bypass installed in the boiler manifold unit protects boiler elements from overheating when excessive hydraulic resistance in the heating system or when the coolant is blocked.
      • Boiler accessibility due to the removable top panel.
      • Ability to switch to a liquid gas.
