    Indoor Water System

    Lidya

    The glass-front Lidya Series is designed for indoor spaces, combining high efficiency with an elegant fireplace-like atmosphere. Its authentic front glass offers a clear flame view, creating a warm focal point while maintaining a long-lasting steel body and strong glass wool and ceramic insulation.

    In addition to space heating, the system can be connected to the installation to produce hot water, making it suitable for integrated heating applications. Draught fan–assisted combustion, automatic fuel feeding and ignition, flue-temperature-based modulation, back-burn protection, and room thermostat control ensure safe, fully automatic operation. Management is provided via a modulating control panel with advanced weekly timer and indoor remote controller.

    All models include a circulation pump, expansion vessel, safety valve, and automatic air vent. LIDYA 15 PLUS and LIDYA 25 PLUS models are equipped with automatic burner cleaning systems, reducing maintenance and ensuring consistent performance.
