Gas condensing boiler / combi boiler FGB-K 24

Gas condensing boiler / FGB-K 24 mixed boiler with perfect integration into complete systems, with indoor air quality, hybridization with aerothermal generation and solar energy. Seasonal energy efficiency of 94%. Air/gas modulation range up to 1:6. Very compact boiler for assembly in any space, ideal for renovation. Optimization of condensation through thermal jump regulation of the variable speed pump. Simple maintenance through Plug & Play replacement parts. Compatible with WOLF regulations (WRS and BM-2). Integration with solar system without the need for an additional solar kit, just with a probe (accessory). Minimum NOx polluting emissions up to 21mg/kWh. Possibility of remote control via internet (PC, tablet, smartphone) with WOLF LINK PRO (ISM7e) interface module (accessory).
