Hydronic balance of the apartment’s heating circuit
Distribution system must ensure that
thermal energy is available for the consumer
at all times and loads, at the right
temperature and the right differential
pressure.
The required differential pressure must
be ensured at all relevant points of a
distribution system, beginning with the
energy production, right through to the
least favorable radiator. Installation of
a differential pressure controller in the
apartment heating circuit guarantees
fault free hydronic conditions.

A strong opinion, which still exists
around, that a heating system can be
properly balanced with section manual
balancing valves and regulated pumps
once again proved to be erroneous in
practice.
In addition to a correctly set differential
pressure controller for the apartment
heating circuit, the individual radiator
valves must also be correctly preset.
Standard compliant differential pressures
in front of the radiator valves now
make flow noises a thing of the past.

What is the EvoFlat system solution
The heating side connection is made
without any system separation. The
heating circuit supply must be fitted
with a differential pressure controller to
guarantee optimum pressure conditions
and flows in the heating system. The
room temperature is controlled with
radiator thermostats. With the mounting
of a thermal actuator with installed
zone valve and using central manual
or programmable room thermostat
enables a convenient, energy optimized
control of the heating.
Example of well balanced heat
distribution
• Proper control of flow and pressure
to each flat with differential
pressure controller
• proper temperature in each room
secured with pre-setting valves
with thermostat sensor on each
radiator
Differential pressure controller is part
of each flat station
