我前室的散热器不会加热。我可以感觉到管道热到恒温阀，但散热器很冷。我已经确保锁定盾牌完全开放，并且我确保所有其他锁定盾牌都只有四分之一到半开。If I turn off every other radiator in the house it still doesn’t get warm I’ve closed both valves open the bleed screw until the water stopped then open the valves individually and the water started to come out again.I have turn the pump and boiler off connected a hose to the vent at the top of the radiator to drain outside. again open the valves individually and water flushed out open both valves together and water flushed out

任何想法我下一步应该做什么
