Dual control A permanent optimal combustion thanks to the dual control of lambda probe and chamber temperature sensor. Automatic cleaning by water jets, enabling an optimal energy yield for a long time. Patented heat exchanger The only biomass spiral heat exchanger, made completely of stainless steel, holds an exchange surface up to 50% larger than a standard exchanger. Our pioneering biomass dual setpoint allows the perfect performance at each installation need, from 27ºC to 80ºC. Return temperature without constrains BCH boilers work smoothly under any condition, either condensing or non-condensing....
