- 12pcs floor FCUs of 6.36 kW type are installed in front of the windows to prevent the formation of condensation and cover the heat losses.
- The heating of auxiliary rooms on the first floor - aluminum radiators with number of gladiers according to the capacity required for the respective room and indicated on the schematic, as well as tower rails for the wet rooms.

The circulation of water from the water distribution headers to the individual consumers is realized by means of circulating pumps "GRUNDFOS" with flow and pressures according to the calculated ones. The water headers are connected with bypass with a butterfly valve Ф125. The main pipelines for the heat supply will be made of steel seamless tubes and the rest of the PPR Stabi. All pipes will be insulated with microporous rubber б = 13mm.
