A new method of the hydraulic balancing of heating circuits

Reduction by half of the energy consumption of the pumps thanks to the HeatBloC MC

Peter Pärisch, graduate engineer (Dipl.-Ing.)
In the article regarding the 12th REHVA World Climate Congress 2016 in Aalborg (Denmark), the HeatBloC MC system of PAW is compared with mechanical differential pressure regulators. Simulations of a building with 5 heating circuits have shown an energy saving of 40 to 65 % compared to the mechanical differential pressure regulators. The influencing factors of the valve authority and the pressure losses of the boiler circuit have been examined. The bigger the valve authority and the pressure losses are, the more pump energy is wasted in mechanical differential pressure regulators. The HeatBloC MC system always puts as much pump energy as necessary into the system in order to overcome the pressure losses and to cover the heat demand. The dynamic hydraulic balancing with the HeatBloC MC system thus allows an energy- and fuel-efficient operation of the heating installation.
