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?

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.


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.


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.


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。


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。

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.




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.



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.


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.
