Hydraulic balancing

Good to know!

HeatBloC MC DN25For the hydraulic balancing of a heating installation, not only the radiators must be balanced out among each other, but also the heating circuits at the distribution manifold.
The balancing of the distribution manifold is a necessary condition for a functioning hydraulic balancing of the radiators. Only both aspects together ensure a comfortable heating of all rooms and an energy-efficient operation of your heating system!

Hydraulic balancing of the distribution manifold

The heating circuits of the HeatBloC® MCom series are equipped with an electronic control of the differential pressure. The MCom controller measures the differential pressure between the flow and the return and appropriately presets the revolution speed of the pump via a PWM signal. The resulting decoupling of the consumer circuits of the generator circuit means that the flow rate in the consumer circuit is only influenced by the thermostatic valves, i. e. the heat demand. Modifications of the pressure loss in the generator circuit by a change of the mixing valve position or of the total flow rate are automatically adjusted. The automatic, dynamic balancing of the distribution manifold avoids the mutual influence of the heating circulations. The high valve authority of the thermostatic radiator valves results in a stable control behaviour of the latter.

Compared to a mechanical differential pressure controller, a HeatBloC® MCom saves at least 50 % of pump energy with the same additional costs, while assuring the same comfort.

Hydraulic balancing of the radiators

heizungsabgleich Whether you carry out the hydraulic balancing of the radiators with preset thermostatic valves or with dynamic valves, the HeatBloC® MCom supports you in doing so. The table values of the preset thermostatic valves usually refer to a differential pressure of 100 mbars, dynamic thermostatic valves need a minimum differential pressure of, for example, 150 mbars. Easily set the corresponding value at the controller and start the hydraulic balancing.

Alternatively, our PAW MCom app supports the metrological, hydraulic balancing of the radiators. All you need are radiators which can be throttled and our communication set as an interface between the MCom controller and the app.  The communication set establishes its own WLAN and serves as an interface between the MCom controller and the app. Thanks to the newest pump technology from Grundfos, which is implemented in the UMP3 and in the UPMXL, you don’t even need a flow rate sensor. The pumps are used in heating circuits with the nominal diameters DN 25 and DN 32 (UMP3) as well as DN 40 (UPMXL).

Only two steps to the hydraulic balancing

Step 1: Record data

Record all heated rooms and enter the standard heating load, the desired inside temperature and the standard thermal output of the radiators.

Step 2: Balancing of the radiators

The app supports the balancing of the individual radiators. For this purpose, take your smartphone with you to the radiator and reduce it to the specified value.
