Grundfos MIXIT allows the construction of just one, instead of three, stations in a residential complex in Hungary

The traditional distribution of heating energy at district heating follows a collective supply model – from the central station to the internal installations at the buildings – continuously and without relation to the differences in the needs of individual consumers. In Tatabánya, Hungary, however, the local heating supply organization T-Szol has decided to apply a different approach – when it’s necessary to establish a new subnetwork for four housing complexes (three blocks and one collective of houses), the company integrates a dynamic system, which accounts for the different heating needs of every consumer. For this purpose, Grundfos' MIXIT mixing loop solution is used, and the company explained more about the subject to BalkanEngineer.com.

During planning of the subnetwork for the 3 blocks and collectives of houses, T-Szol decided to take into account the different heating burdens and the requirements regarding preliminary temperature of the residential units – at the same time ensuring the necessary flow and temperature for water in the different buildings. "In a traditional system, we would place a subscriber station in each of the four buildings, but since this approach would lead to occupying valuable space and higher overall costs and potential losses, T-Szol chose an alternative option - building only one station and balancing the system using MIXIT," Grundfos Bulgaria explained.

Grundfos MIXIT is an innovative all-in-one solution for simplified commissioning and optimal balancing of heating and air-conditioning building systems, which combines all traditional components into one common device. “MIXIT combines between 8 and 12 separate components typically required for building HVAC systems, thus reducing installation and commissioning time by up to 50%,” the Bulgarian company emphasized, adding: “Thanks to automatic balancing according to system needs, it is possible to save up to 25% of the required heating energy, and through continuous monitoring of the HVAC system, energy consumption can be further reduced by up to 15%.”
