Metro Therm HVAC boiler 255 E Sol

Metro Therm VV heater 255 E Sol with solar coil

METRO 255 (E) Sol is an enamelled water heater for efficient use of solar heat.

The boiler has two coils of 0.75 m² and an electric cartridge of 3 kW. The lower loop is intended for solar collectors and the upper loop for connection of, for example, underfloor heating for smaller areas. The electric cartridge only heats the upper part, which corresponds to approx. 85-100 litres.

Construction

The water tank consists of enamelled pressure vessel steel which provides the highest corrosion resistance. The construction is pressure tested at 13.5 bar and approved for a maximum operating pressure of 10 bar.

Heating element in protective tube - withstands all water

The Sonett Cabinet, Modul and Agricultural series have indirect heating. The heating element consists of a heating coil. As the water does not come into direct contact with the heating element, the risk of power reduction is eliminated. The steel tube is mounted through a flange connection, easy to disassemble for inspection or cleaning.

Enamelled container with protective anode = extra safety

The METRO boilers have a special emapan enamel with the same expansion coefficient as the pressure vessel steel, which means that the enamel does not crack and thus exposes the steel to rust attack. The enamel layer is bacteria- and lime-repellent and resists all types of water. There are no metals that can affect the quality of the water. More than 50 years of experience is behind the special enameling technology. All enameled water heaters from METRO THERM have a protective anode. When enamelling, microscopic pores can appear which means that the water can come into contact with the steel surface. The anode sacrifices itself against the pores and covers them with magnesium.
