We have recently installed a condensing boiler. The radiators that we have are jaga strada with thermostatic valves. Our problem is that three of the radiators, all on one loop, are not heating fully. The inflow pipe is extremely hot but the outflow pipe is barely warm, We have bled the radiators. All other radiators are fine. We have increased the water temperature of the boiler to 70 degrees celcius to no avail.
