In a recently built kindergarten in Rokietnica near Poznań, a heating installation was executed with the use of WATTS pump groups. A two-circuit manifold VB20 and two HKM20 pump groups were applied to operate heating circuits with distribution to both floors. The manifold, together with the floor groups, supports underfloor heating over a floor area of 520 s qm. 6 underfloor heating manifolds were used, each with 6 circuits. The installation includes a 45 kW boiler (and 200 L storage tank), which additionally has the task of preparing hot water for the building. Installations in the building were executed by PHU Baseco Rokietnica.
