Just an idea. it may not be 100% correct

mpoon(无牌电工....)
how old the house is?
Most of the time, the older blower fan in the heating system would make certain level of noise. one of the reason is, the blower fan is out of balance due to too many dirt/dust build up on the blade, 2nd if the blower fan bearing is too dry, it also will make noise. as well, the air duct that connected too the blower fan will acting like a "sound box" "共鸣箱效果"it will amplifies the noise that generated by the out of balanced blower fan.
if house is old. clean the fan blade and lub the bearing,By the way, older then 5 years is old....

  • 枫下家园 / 美丽家居 / 请教：暖气炉（地下）一工作就发出轰轰隆的响声，尤其在睡觉的时候（二楼）会觉得很吵，直到达到的设定的温度才能安静下来，是不是炉子有什么问题？还是房间隔音能力太差？ 请有经验的同学帮忙解答一下吧。 谢谢！ -lijiatong12(老葛); 2007-12-31 (#4152255@0)

    • 我家的也很吵，启动起来感觉象是开火车。我也在想是不是我家炉子有什么问题，还是就是这样子的，可是我表姐家的就不响啊。 -hoho111(萝卜心小花@^_^@); 2007-12-31 (#4153326@0)
      • 朋友家也说没这么响，会不会是因为炉子太老还是房子的结构有问题？ 总之这对睡眠轻的人来说挺痛苦的。 -lijiatong12(老葛); 2007-12-31 (#4153755@0)
        • 其实我家炉子原来也没这么响的，只是上次清理完炉子后出现问题，又找人来修，本来都修好了，那个修理工为了让炉子工作的更猛，狠狠的敲了炉子几下就变现在这样了，当时问他为什么声音变大了，他说本来就应该这样的。 -hoho111(萝卜心小花@^_^@); 2008-1-2 (#4157016@0)

      • 能说得详细些吗？ 谢谢。 您的意思是说因为电压高了？ 有没有改的可能呢？ -lijiatong12(老葛); 2007-12-31 (#4154113@0)

        多谢电工解释得非常详细。 另有问题是什么时间适合去清洁扇片和轴承加油呢？一定要等这个冬天过去还是～～再就是这个活是自己就可以做还是一定要找专业人士？再次感谢

          Should not be any problem DIY. But,do it after the winter. because the heating must shut off to do this job.

          However, what you can do now, look around the blower fan compartment, it is easy to spot the fan bearing, if don't see any bearing, it may be just a Bronze Bushing (套筒軸承) add some oil to it.

          Also have you clean the dust/air filter regularly?

    • 连接炉子的duct的尺寸不当是产生噪音的一主要原因。尺寸小或者截面长宽比过大，都会增大噪音。 -sunway365(唯心); 2008-1-1 (#4155639@0)

        多谢唯心， 如果最终是这个原因的话，估计就一定要等冬天过去，找专业人士改了, 您知道哪里去有这样的专业人士吗？
