4.8.2.1 Product features
The Aquarea tank is a high-performance, and modern tank, which was developed especially for
the requirements of the Aquarea heat pumps. The hot water tank with a volume of 185 litres is
located in the upper area of the tank and a smaller buffer tank with a volume of 80 litres in the
lower area. This makes the Aquarea tank ideal for domestic water heating and heating usable in
single family houses. The complete model ensures very low standby losses and quick assembly
due to the pre-installed assembly groups such as 3-way valve or E-Heating element hot water
tank (with safety thermostat and fault reporting contact)
The use of the Aquarea tank helps implement multiple functions efficiently and easily, such as:
● Domestic water heating
● Hydraulic disconnection of heat pumps and heat consumer circuit
● Ensuring minimum volume in the heating system
● Buffer function for optimum operation of the Aquarea heat pumps
Note the respective installation instructions enclosed when installing the Aquarea tank. Other
accessories are also mentioned in it, which are needed for the installation of the hot water-/
buffer tank combination in the heating system and must be provided by the client.
