Circulating pumps
CAUTION.
Always note the model.
Do not use regulated circulating pumps.
Circulating pumps and domestic hot wa-
ter circulation pumps must be multi-stage
pumps.
Water heating
Water heating with the heat pump requires an addition-
al hot water circuit, parallel to the heating circuit. Make
sure that the heating water charge is not channeled
through the buffer tank of the heating circuit.
“Hydraulic connection” instructions.
Hot-water tank
If the heat pump will be used for heating hot water, you
must integrate special hot-water tanks in the heat pump
system. The storage volume must be sufficient so that
the required hot water quantity is available even during
a power outage.
NOTICE.:
The heat exchanger surface of the hot wa-
ter tank must be dimensioned so that the
heating capacity of the heat pump is trans-
ferred with minimal spreading.
We offer a variety of hot-water tanks for you to choose
from. They are optimized for use with your heat pump.
NOTICE.:
Integrate the hot-water tank in the heat
pump system corresponding to the hy-
draulic diagram for your system.
Pressure relief
Equip the heating circuit in accordance with local stand-
ards and directives with a safety valve and an expansion
tank.
Also install filling and emptying devices, shut-off devices
and non-return valves in the heating circuit.
Overflow valve
Always use an overflow valve to ensure the minimum
flow rate of the heating circuit volume flow through the
heat pump. The overflow valve must be dimensioned so
that the minimum flow rate of the volume flow through
the heat pump is ensured when the heating circuit is shut
off.
Buffer tank
The hydraulic connection of the heat pump requires a
buffer tank in the heating circuit. The required volume of
the buffer tank is calculated based on the following for-
mula:
V
buffer tank
=
Minimum flow rate of heat circuit volume flow / hour
10
For the minimum flow rate of the heat circuit
volume flow, see overview “Technical data/Scope
of delivery”, “Heating circuit” section.
In mono-energetic air/water systems, integrate the buff-
er tank in the heating water outflow (forward flow) be-
fore the overflow valve.
