7.2.1 Heat pump with underfloor heating

The use of steel pipes and other steel components is not permitted in
the heating circuit of underfloor heating systems. Use stainless steel,
copper, brass or plastic - such as PE - for instance.

In case of single room control, a buffer tank (corrosion-free) and a differ-
ential pressure overflow valve must be installed in the heating system
(see diagrams). 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.
7.2.2 Heat pump with radiators

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 system must then be marked accordingly and the mainte-
nance instructions of the supplier must be followed strictly.

Heating systems with radiators require the installation of a buffer tank
(connected in parallel) (see diagrams). The size of the tank must be cal-
culated. 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
(P11108).

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 en-
sure that they are compatible to stainless steel, copper or nickel. Failure
to comply can result in destruction of plate heat exchanger!
7.2.3 Heat pump with swimming pool
The following components are required for heating a swimming pool:)

1x 3-way motor ball valve (F10453)

1 x swimming pool sensor with immersion sleeve (Z14783 and Z13344)

1 x swimming pool upgrade kit (P11108 or P1159)
