Heat pumps Double storage tank WP-VA-Kombi 200/80 stainless steel dwh tank with Buffer tank

Heat pump combination tank WP-VA-KOMBI
with integrated stainless steel domestic
hot water (DHW) tank with 200 litres
and buffer tank with 80 litres. The
large stainless-steel heat exchanger in
the DHW tank ensures very efficient heat
transfer and a high hot water output.
The corrosion resistant stainless-steel
DHW tank is characterised by its low
weight and the hygienic and food-safe
surface quality. Cleaning flange and
connection for circulation and immersion
heater included. The buffer tank made of
steel with connection for an immersion
heater makes the tank a compact
all-in-one solution. It serves as a
hydraulic separator for a heat pump.
The high-quality hard foam thermal
insulation minimises energy losses.
