Does Hot Water Kill Bacteria? Here’s 6 Things You Should Know

You probably don’t think about your water heater too often. As long as it’s working and you’ve got hot water, what is there to think about? As it turns out, there may be more to consider than you think. An improperly maintained water heater is a breeding ground for bacteria. This bacteria can get into your water supply and end up causing foul smells, as well as have an impact on your overall health. But how can you stop this from happening? Does hot water kill bacteria?

How Does Bacteria Get in a Water Heater And Does Hot Water Kill Bacteria?

细菌无处不在。有些细菌对您的健康和福祉具有危险,而另一些细菌则完全无害。尽管细菌无处不在,但某些环境比其他环境更容易感染某些类型的细菌。

温暖,潮湿的地方是细菌滋生的场所,而放置不当的热水器的地面应为零。在适当的温度下,细菌可以在鼻下生长并成群繁殖。考虑到这一点,半定期检查热水器并确保始终将其设置为正确的温度非常重要。

热水器中会生长哪种细菌?

热水器中可能会繁殖一些细菌,但最常见的是军团菌。

军团菌是引起细菌 军团病. You can get Legionnaires’ disease by inhaling microdroplets of legionella-contaminated water. Legionnaires’ disease is a severe type of pneumonia. It causes lung inflammation, head and muscle aches, high fevers, and sometimes bloody coughs. It’ll also give you chest pain, shortness of breath, and mental confusion as it worsens.

退伍军人病虽然可以治疗,而且无法传播,但离您想要得到的东西还很远。对于免疫系统较弱的人和老年人而言,这甚至可能是致命的。考虑到这一点,确保军团杆菌细菌不会在热水器中生长很重要。

Beyond legionella, your water heater can become infested with sulfate-reducing bacterium. When this happens, your water may have a distinct “臭鸡蛋” or sulfur smell 对它。这是完全不愉快的,如果不纠正的话会变得更糟。

Corrosion and rust in your water heater can also cause bacteria. You should do routine checks on the maintenance of your water heater. If it’s in need of repairs or if your water heater is leaking, don’t hesitate to call a professional.

我如何知道热水器中是否有细菌?

If your water smells like 臭鸡蛋, chances are its a bacterial issue. You may have too much magnesium in your water, or hydrogen sulfide gas. Beyond that, it can be hard to tell if there are bacteria in your water heater. Bacteria isn’t visible, meaning it could be present without you knowing.

Considering this, there isn’t really a way to know if there are bacteria in your water heater. You can, however, reduce the chances of bacteria in your water heater. The best way to reduce the chances of bacteria in your water heater is by paying attention to the heat settings. At too low a temperature, your chances of cultivating legionella and other bacterium are raised significantly. It’s important to learn the perfect temperature to maintain and make sure your heater stays that way.

完美的热水器温度是多少?

First, let’s talk about the most deadly temperature for bacteria growth. Temperatures between 95°F  and 115°F 为退伍军人病菌提供了理想的环境。这个温度范围不仅会促进生长,还会促进繁殖。将热水器在此温度范围内放置太长时间会导致细菌大量积聚。

但是,在120°F下,细菌停止繁殖。但是,这种温度不会杀死细菌-只会抑制细菌。军团菌仍可在此温度下通过淋浴,水槽或任何其他水源传播。

根据 美国卫生工程学会,您应该将热水器设置在135至140°F之间。在此温度下,您将杀死所有军团菌并阻止其进一步生长。这种高温还会杀死可能存在的军团菌之外的细菌。

乍一看似乎太热了,但是您可以采取一些步骤使它更易于管理。此外,它比让细菌在热水器中生长要好得多。热水器中的细菌意味着整个家庭都处于危险之中,尤其是因为军团菌可以在空气中传播。

水温过高的风险

将热水器在135至140°F之间旋转的唯一问题是 烫伤的机会增加.

在这种温度下,您的水会冒出更多的热量,并在短短的时间内烫伤您。您可以考虑在加热后安装防垢设备。它们安装在热水器出口附近,并在流出时将少量冷水与热水混合。

如果您与孩子或老人一起生活,这一点尤其重要。他们可能会不小心在热水上烫伤自己,这可能会造成严重损坏。更改热水器温度时,请务必让家人知道,以便他们做好准备。

热水器温度会自行变化吗?

Even if you set your water heater to the perfect temperature, it may not stay that way. The water heater’s temperature may change as cold water circulates into it. It may also change if you have an old water heater, or one in need of maintenance. This makes it very important to check on your water heater’s temperature settings occasionally.

通过保持热水器的最高温度,可以大大降低细菌和可怕的鸡蛋臭味的风险。

如果我的水闻起来像烂鸡蛋怎么办?

As we’ve touched on, there are a few different reasons your water may smell like eggs. Considering this, there are a number of solutions depending on what is causing the smell. One of the easiest solutions is raising the water temperature. By doing this, you’ll effectively destroy the bacteria that may be present in the tank but doing so can be very dangerous and there is easier way to stop that smell.

尝试氯气治疗

如果您的水中存在减少硫酸盐的细菌,则可以用浓水将其修复。 氯化处理. This puts a set amount of chlorine into the tank. However, this is only a temporary solution and will last for 1 or 2 weeks.

Install a Powered Anode Rod

Every water heater has a magnesium anode rod installed in it. This rod is installed to limit corrosion inside the tank and will only last a couple of years. If you want to solve this smell forever, you just need to install a Corro-Protec动力阳极. This powered anode will kill the bacteria that create the rotten egg smell in only 24 hours and doesn’t require any maintenance.
