EKCO.LN2...p
Boiler connection to the central heating system
EKCO.LN2 and EKCO.LN2...p model are equipped with an expansion vessel (capacity:
6l, pressure: 1,5 bar). The expansion vessel is sufficient for following capacities of the
heating system at given temperatures of the medium and central heating system pressure.
Shall the capacity of the wet central heating installation be larger, an extra expansion
vessel should be installed on it.
