The Fin-e patented system is based on an internally finned aluminium profile which is inserted in the rear of the fire tubes in order to ensure complete contact between the surfaces.
The smoke lapping the finned surface give off heat and their temperature decreases significantly, thus limiting energy loss from the stack.
The structure of the boiler is not changed and it regains efficiency without significantly increasing the pressurization in the furnace.
This achieves: strong>
