200 litre buffer tank (enamelled or stainless steel) should be sufficient for this
series.

When the living space controlled by single room control is less than 1/3, a
buffer tank is not required if the remaining 2/3 floor circuits remain open.
8.3.3 Heat pump with radiators (natural cooling not possible)

On systems with steel radiators an effective corrosion inhibitor must be added
and a dirt trap (0.8 mm mesh) connected before entry into the unit. The sys-
tem must then be marked accordingly and the maintenance instructions of the
supplier must be followed strictly.

Heating systems with radiators require the installation of a buffer tank (con-
nected in parallel) (see diagrams). The size of the tank must be calculated. The
heat pump control regulates the temperature of the buffer tank. After the tank,
the components (circulation pump, mixing valve ...) must be controlled with an
optional WATERKOTTE mixing control.

If the formation of deposits is to be expected (e.g. strong contamination)
based on water quality, cleaning must be performed in regular intervals.
Cleaning can be performed by flushing.
Procedure:
The plate heat exchanger is to be flushed with a suitable cleaning agent in
counter-flow direction. If chemicals are used for cleaning, please ensure that
they are compatible to stainless steel, copper or nickel. Failure to comply can
result in destruction of plate heat exchanger!
8.4 Connection to heat source
The following can be used as heat source:

The ground, by connection to a horizontal geothermal absorber (e.g. PE-
pipe20x2) or a vertical geothermal absorber (geothermal probes).

The groundwater, by connection to a well system, using an accessories kit
available from WATERKOTTE to monitor the flow at heat source side and
separation heat exchanger (heat source side).

The layout of the heat source system must be according to the
WATERKOTTE dimensioning information.

Refer to the performance table to find the volume flow for the corresponding
heat pump.

The heat source connections (1¼“) feature an external pipe thread for flat-
sealing connections with union nut and insert.
A circulation class A pump is installed at heat source side. Optional equipment,
energy class A pumps: The circulation pumps are offered with internally coated
housing (plastic).
