如果您的热水器正在隆隆,弹出或制作其他噪声,则此专家指南将帮助您排除故障并解决问题。包括用于天然气和电动热水器的DIY修理。

Hot water heater noises may have any of several causes. A noisy water heater is usually an indication that minor maintenance is needed. Few are a serious concern.

在本文中,您将发现一些更常见的热水器噪音以及您可以采取的步骤消除它们。

当冷水供应被加热时,溶解的硬水矿物重结晶并形成尺度和沉积物。你的水是“更难”(见How to Test for Hard Water),这些矿物沉积物的速度越快。

The scale cakes onto interior surfaces and accumulates as sediment buildup at the bottom of a storage water heater tank.

To minimize the amount of scale in your water, you can have a plumber install an anti-scale system on your water line. This system keeps the minerals suspended in the water so they are less likely to stick to the water heater equipment.

控制硬水矿物最完整的方法是将抗级系统与一个结合起来水软化剂,which removes minerals from your water.

如文章所讨论的那样How a Storage Water Heater Works,热水器具有内部的镁或铝阳极杆,以最大限度地减少腐蚀性矿物质。这通过罐的顶部插入。

隆隆,爆裂或噼啪声

如果这听起来像是砾石沸腾在底部of your gas water heater’s tank, well—in some ways—it is. But the “gravel” making that rumbling noise is actually sediment from minerals and hard water scale.

随着热水器罐底部的沉积物被燃烧器直接加热,它变热。然后沉积物可以咆哮和翻滚。这使得隆隆声。

Or, when the gas burner fires, it boils the water that is trapped under the sediment. The result is a popping noise.

这些问题的解决方案是冲洗你的热水器

This rumbling or popping sounds don’t mean that your water heater is dangerous. But, it does indicate a problem. Because the burner’s heat has to travel through the layer of sediment to reach the water, the water heater’s efficiency is reduced.

此外,鳞片的大块可以从热水器的内表面断开并穿过热水管道。这些块可以在一个关口处堵塞,阻碍水流。

This is why it’s important to flush the tank every few months.

在电热水器中,秤最终将加热元件涂在罐内。随着元素变热,他们烹饪刻度,水被困在它下面。结果可以是热水器弹出噪音,噼啪声噪音或嘶嘶声。

Vibration or Humming Noise

燃气热水器中的振动噪声通常由罐底部的缺陷燃烧器引起。燃烧器内的金属板或翅片可以随着时间的推移偏转,并且当燃烧器接通时互相摩擦,导致嗡嗡声或振动。

该视频显示如何通过简单地弯曲或修剪燃烧器附近的金属支架来固定振动。请注意,制作他显示的修复类型可能会使您的保修失效。在此视频之后,您也可以自己更换燃烧器。

Sound of Water Boiling

如果听起来像水沸腾的水桶内,请折断热水器的温度。

Next, test the T&P valve to make sure the water heater can release built-up pressure. Lift its lever and make sure hot water comes out of the discharge pipe. Then release the lever. It should snap back down.

If it doesn’t work, the T&P valve may need to be replaced. SeeHow to Replace a Water Heater T&P Relief Valve

如果这不是你想要自己的工作,请致电热水器服务人员或水管工。这可能表明过热和危险的压力累积。
