Enamelled bivalent heat pump domestic
hot water (DHW) tank WP-S 500, double-
wound XXL high-performance heat
exchanger ensures very efficient heat
transfer, minimal pressure losses and
a high hot water performance. The lower
heat exchanger with double floor is
perfectly suited for the use of solar
thermal systems. In monovalent
operation, the heat exchangers can be
connected for greater efficiency and an
increase in total system efficiency. The
two-layer enamelling, protected by two
magnesium protective anodes, is durable
and highly resistant. Cleaning flange,
connections for circulation and
immersion heater, thermometer and sensor
connection as standard. The high-quality
hard foam insulation ensures minimal
energy losses.
