PelTec II Lambda steel hot water boilers are intended for burning with wood pellets. The boiler is equipped with a burner for burning wood pellets with the function of automatic ignition, self-cleaning grate and flue. The built-in lambda probe optimizes pellet combustion, which directly affects “cleaner” combustion and reduced fuel consumption. The function of automatic cleaning of the flue pipes ensures uniform heat exchange and a high and uniform level of utilization of the boiler. Multifunctional digital boiler regulation with a 7″ color screen, sensitive to touch, in the basic version also offers the possibility of modulating operation of the boiler with one heating mixing circuit and one PTV circuit with recirculation. The return line protection is built in, which ensures the correct operation of the boiler even at lower temperatures. Pellet tank with pellet level sensor is part of the boiler.
