The Trigon XXL Plus is a fully modulating gas condensing boiler with a control unit that adapts the modulation ratio automatically to the heat demand by controlling the fan speed. The whirlwind mixing system adjusts the gas ratio to maintain optimal combustion and efficiency. Flue gases exit through the back of the boiler. The return water enters at the lower section, where condensation occurs, then moves upwards, ensuring efficient heat exchange.
