我住在一个高度的公寓。木结构。该综合体建于3年前。这些单位的管道是“CPVC”。这种噪音在过去6个月左右开始。
我们正在第二级。每个公寓机都有自己的加热和热水系统。每个单元都有一个Aquatherm加热装置，它是具有再循环系统的组合热水/气体燃烧加热系统。该加热系统从热水箱系统中加热。热水罐位于未加热的房间内，连接在外部阳台上。我们位于亚特兰大格鲁吉亚，冬季不严重，但冬季的温度下降到晚上冻结。噪音从我上方的单位发射。我在二楼，楼上的单位的热/冷水管穿过我的天花板。主卧室天花板和厨房里听到了噪音。客厅/用餐区没有听到的是，将主卧室和厨房区分开。 This sound occurs when the weather is cold and is very predominent early in the morning say around 5:00am when the person above us turns on his shower.The ticking/knocking/banging also occurs when the Aquatherm heating systems starts up at 3:30am when below freezing outside. It seems to be the hot water line. It starts as a ticking noise in the pipe. The noise starts off slow and then accelerates and lasts for about 10 - 20 seconds. The ticking noise develops into a banging/knocking noise and then disappears. We can hear the shower continuing to run after the noise subsides. We will hear the noise again at night at 11:00pm when the person above us turns on his shower again or when the Aquatherm heating unit calls for heat primarily when the temp is below freezing. The noise seems to occur after a long period of time where the plumbing is at rest and not being used.
我们最近安装了一个膨胀罐到热水系统上，这没有消除噪音。
我们的单位与上述单位相同，但是当我们使用我们的淋浴时，我们并没有这种情况下敲击噪音。
请帮助，任何一个人都可以用这种噪音识别，可以建议解决方案。
热水箱有问题吗？
