Folks,
As the title suggests, am interested to know what other flow rates posters are experiencing when multiple UFH loops are calling for heat? With one/two loops calling for heat, I note my system is running around 5-6 litres/min but when there are several loops all calling for heat, it drops to around 2 litres/min. Perhaps this is normal but would take some comfort in knowing this is the case, or alternatively would welcome a view as to how I might improve it. For info, all rooms are individually thermostat controlled with the stats opening the individual actuators on each loop.
