Good day everyone. In our new multi-family house, we have some problems with the heating system (pellet boiler with underfloor heating). The flow temperature of the underfloor heating is correct after a maintenance. But now the underfloor heating is making a terrible rushing noise. Also at night. If you briefly close the valve in the distributor box, the rushing stops. Before I call the heating engineer again, I wanted to get some tips here. Could it be that the heating system was refilled and there is too much air in the system? Or why is the underfloor heating rushing now? Before the maintenance, it was whisper quiet.... Nothing was adjusted at the distributor box in my apartment. Not even the room thermostats etc. Many thanks!
