WALL HUNG GAS BOILER
Efficiency till 104% at affordable prices

• High and constant efficiency;
• Projected for maximum efficiency and economy according with the last European normative – low energy circulation pump – EFFICIENCY CLASS –A – 4 stars (norm 92/42/CEE);
• High confort on domestic hot water circuit; oversized brazed plate heat exchanger – classified 3 stars (EN13203) on confort DHW;
• Wall hung gas boiler easy to install due to its reduced size;
• Flowmeter for domestic hot water flow debit;
• Advanced pressure sensor – assure intelligent protection at overpressure and low pressure;
• Control panel LCD which assure a evaluated graphical user interface;
• User and service operation mode;
• Possibility of connection for: cronothermostat and external temperature sensor;
• Air vent installation mode – the circulation pump operates beside the burning mode, as so to air vent the installation;
