Effective three pass boiler The pipes of the third smoke pass are decisive for the attainment of the maximum efficiency. The new patented technology has allowed to insert special aluminium multi-fin structures inside the thick steel pipes. In this way are born the new “EASY STREAM Pipes” of 1 1/2” diameter.
