Heat pump domestic hot water tank WP-300 High-performance with double register

Enamelled domestic hot water cylinder
WP 300, suitable for operation with heat
pumps for efficient and reliable DHW
heating. The double-wound high-
performance heat exchanger guarantees a
very high hot water output with minimal
pressure loss thanks to the excellent
heat transfer. The durable double-layer
enamelling, protected by a magnesium
protective anode, guarantees a high
level of resistance. This tank has
a cleaning flange and connections for
circulation, thermometer and a sensor.
There is also a connection for an
electric heating element for emergency
heating or to use excess PV power.
The 75 mm PU rigid foam insulation
minimises energy losses and maximises
efficiency.
