4.8 Accessories
4.8.1 Domestic hot water tank
4.8.1.1 Product features
The hot water tank is for preparation and intermediate storage of the hot water. Besides the
heat from the Aquarea heat pump, solar heat can also be stored in an intermediate storage by
integrating a solar system and used. An E-heating element with a power of, say, 3 kW addition-
ally ensures maximum comfort, even at very low outside temperatures, and can also be used for
sterilisation.
Panasonic offers various storage models in different sizes for easy hot water preparation for
different requirements.
The scope of delivery for the various storage types includes the following:
● E-heating element
● Safety valve, provided loose (only stainless steel hot water tank only)
● Dip sensor with sleeve and 20 m cable
● Protective anode (enamel-steel hot water tank only)
● Thermostatic overload protection
● Adjustable legs
● Insulation in polyurethane foam
● 3-way switchover valve set PAW-3WYVLV-SI or CZ-NV1 available as optional
accessory.
Observe the respective installation instructions enclosed when installing the hot water tank.
Other accessories are also mentioned in it, which are needed for the installation of the tank in
the heating system and must be provided by the client.
Standard hot water tank (stainless steel)
PAW-TD20C1E5 / PAW-TD30C1E5
The standard hot water tanks are compact
tanks in stainless steel, which guarantee a high
life cycle. They are available in two sizes with
200 and 300 litre capacities. Both these models
with energy efciency class A need no protec-
tive anode and are maintenance-free.
