Vertical Enameled Water Heaters With Two Coils 200-400 Serie Se

Vertical Enameled Water Heaters With Two Coils 200-400 Serie Se

200, 250, 300SL, 300, 350, 400


TWO HEAT SOURCES thanks to the two spiral coil pipes connected to a central heating boiler and to solar thermal collectors. Fast domestic water heating thanks to the spiral coil pipe.

WATER IS HEATED during the heating season by central heating system connected to upper coil,and during the summer by solar thermal collectors connected to lower coil. Water can be additionally heated up by an electric heater which can be optionally installed.

DURABILITY is ensured by a magnesium or titanium anode and ceramic enamel, fired at 850OC.

INSULATION made from polyurethane foam.

AESTHETIC HOUSING made of leatherette. Available in 3 colour versions: grey, red and dark blue.
