Heat pump combination tank WP-KOMBI with
integrated enamelled domestic hot water
(DHW) tank with 380 litres and heating/
cooling buffer tank with 130 litres. The
double-wound XXL high-performance heat
exchanger in the DHW cylinder ensures
very efficient heat transfer, minimal
pressure loss and a high hot water
performance. The two-layer enamelling,
protected by a magnesium protective
anode, is durable and highly resistant.
Cleaning flange, circulation connection,
thermometer and sensor connection as
standard. Connection for immersion
heater when replacing the flange plate
possible. With the buffer tank at the
bottom, also with a connection for an
immersion heater, this tank is a compact
all-in-one solution. The tank acts as a
hydraulic separator for the heat pump
and can be used for both heating and
cooling. The high-quality diffusion-
tight insulation ensures minimal energy
losses.
