Domestic hot water tank BW-0 300 enameled tank, 0 heat exchanger

Enamelled hot water cylinder BW-0 300
without heat exchanger - ideal for
efficient DHW heating due to external
heat exchangers. The universal
connections offer a high degree of
flexibility and enable individual
utilisation. With an external heat
exchanger, the entire volume can
quickly and evenly be heated to the
desired target temperature. The durable
two-layer enamelling combined with a
pre-mounted magnesium protective anode
(convertible to a powered anode)
ensures high corrosion resistance and a
long service life. The cylinder is also
equipped with a cleaning flange, a
circulation connection, thermometer,
sensor connection and various free
connections. The connection for an
immersion heater enables the use as an
emergency heating system or the
integration of surplus PV electricity.
The 75 mm PU rigid foam insulation
minimises energy losses and increases
the overall energy efficiency.
