How Long Does It Take to Boil Water?

Useful information regarding this question and its nuances

kettle boils

We simmer water every day and even several times a day. And we are so used to this simple procedure that hardly ever wonder about the water boiling time. 

However, this information may be useful, for example, when cooking and in many other situations.

How long does it take for water to boil? 

In this article, we have tried to collect as much information as possible regarding this question and its nuances.

Let’s figure it out!

Everything You Ever Wanted to Know About Boiling Water Time

First of all, why could it be so essential to know how much it takes for water to simmer? Of course, the most obvious and, probably, the widespread answer would be “to know when I shall load the casserole with the vegetables/eggs/meat to boil”. 

How much water do you drink per day?
1,5 liters
16.04%
2 liters
28.3%
1 liter
16.04%
I do not know
39.62%

But that is the typical reason for the housewives and, perhaps, cooks who need to know precisely when to start preparing the food without overcooking it.

Nevertheless, being aware of the term you need to simmer water can be, no more no less, life-saving. For example, if you are traveling somewhere in the wild nature, you will need to ensure that the water from the stream, for example, is good enough to drink. To become safe, it must be boiled and – what is even more important – you must know exactly how much it must be boiled before it can be drunk safely.

So, to give at least some common idea about boiling water specifics, we would advise learning the following tips.

How long do you boil water?

It depends on whether you are using tap or filtered faucet liquid.

In the first situation, it is harsher and it has more impurities, in the second case, it is softer.

Because of this, filtered water takes less effort to bring it to seethe. 

So, to make faucet H2O safe to drink, keep it seething for 120 seconds after it was brought to a boiling point. It will destroy the germs and make the water softer.

Also, take into account the volume of the pot you are using as large pots take a longer-term to seethe than the small ones.

How long will it take until the water boils?

First of all, everything hangs upon on the proportions and volume of your pot or the tank you are using for this purpose.

Also, the thing that matters is how big the fire is that you are using.

In addition, the type of water you are boiling also counts because faucet water will take more effort to simmer it compared to the filtered water, for example.

Anyway, the average period that passes until water starts boiling is usually ⅙ of an hour.

  • Why does water take so long to boil?

You have probably noticed many times that it takes a pretty extended period to seethe a kettle or a casserole to make yourself some tea or cook spaghetti!

Why is it like that?

Well, as you probably know from the school lessons of physics, water is a pretty bad conductor of heat because it gets warm too slow. In addition, the structure of water is very fluid and its molecules are always on the move. That is why it takes more effort to heat up water than, for example, the air.

On the other hand, water keeps heat longer that is why, once boiled, it can stay hot for quite a extended period.

  • How long do you have to boil water?

Giving water enough space to seethe after it started rolling allows destroying the harmful germs and impurities it may have which makes it safer for drinking.

Depending on whether you are boiling faucet water or filtered water, the boiling term may vary.

For faucet water, 120-180 sec of boiling is usually required, whilst filtered water is enough to simmer for one minute.

And remember that boiling term means the period the water keeps rolling after it was set to seethe.

Boiling some water may seem to be not a big deal, however, when it comes to doing this, people often face different and unexpected difficulties and questions.

To ease your life, we collected the most frequent of them.

  • How long does it take to boil water on a stove?

The boiling time hangs upon how strongly you heat the water. Also, the size of the tank matters.

If you heat it up using a medium fire/power in one-liter pot or casserole, then it may take approximately ⅙ to ¼ of an hour for the water to simmer.

If you are boiling water on a usual stove in a tank that conducts heat well, then it will take you approximately one hour to see the one gallon of water (if the water was cold when you started to simmer it).

Of course, if the initial conditions were different (for example, weak fire or worse conductive abilities of the tank), then the process of boiling may take more time.

What is the average time to boil water?

Normally, if you are boiling it on a regular stove in a one-liter pot that has the good heat-conductive ability, it takes something like fifteen minutes.

  • How long does it take to boil six cups of water?

One 200 ml cup takes something like 120 sec to simmer which means that six 200 ml cups will take twelve minutes to boil this amount of liquid.

  • How long does it take to boil four cups of water?

Again, if we are talking about 200 ml cup size, then four cups will need about 8-10 minutes.

  • How long does it take to boil four quarts of water?

Since it requires three minutes to seethe eight ounces of water in a 1000 watt microwave, then 3.7 liters will require something like fifty minutes to get boiled respectively.

  • How long does it take a pot of water to boil?

A one-liter pot that has a good heat-conducting ability can be boiled in fifteen minutes on the maximum fire.

  • How long does it take for water to boil in a microwave?

Everything depends on how much water you need to seethe and how powerful the microwave is.

For example, a glass of water takes from two to three minutes to seethe in a 600-700 watt microwave.

How to Simmer Water For Different Purposes

Every one of us knows how water simmers, right?

We grab a casserole full of liquid and place it over the fire. Of course, we know that boiling on medium heat will take longer, that is why for cooking most people prefer using high heat. Like that, our tank will simmer quickly. 

We also know that when we leave the lid on top of the vessel, its content reaches boiling point faster.

But did you know that several different methods of simmering water exist hanging upon the particular result we want to get? It means that for cooking and for making water drinkable we can’t use the same method!

And here you can learn the best recipes for bringing water to the simmering point quickly and easy.

Boiling H2O for cooking

So, we want to cook something. The first thing to do is to find a vessel with a lid. It is needed for making the content to roll faster. If we cover the top of the tank, we will enclose the heat, the temperature will rise faster, and our water will simmer. 

  • After the tank is chosen, fill it with water.
  • Use cool liquid since hot water can have harmful components from the pipes.
  • Also, the tank must not be full. First, because the food will be added into it (since you’re cooking) and that needs space, and second, the full casserole can splash you with hot water and leave burns.
  • Place the vessel over the high heat with the lid closed. 
  • After it started rolling, it’s time to add food to cook. We don’t recommend you add it before the liquid reaches the rolling point unless the recipe calls for it. Otherwise, it can lead to food getting tough and less flavorous.

Some say that adding salt can raise the water temperature and bring it to the boiling point sooner but that’s not correct. Adding salt only effects on food’s taste, not on the speed of simmering.

After the water is at the boiling point, bring the fire down, otherwise, it’ll turn into steam ay faster.

Also, it’s better not to remove the lid while cooking since the food will need more time to get ready, and the liquid will boil out faster.

And of course, don’t add cool water to the already boiled. It can damage the taste of your cooking.

This easy method will help everyone cook faster and keep the food delicious.

How to purify water?

We may need to do this when we are on the road or on a long tour in the wild.

Bringing water to a high temperature helps to remove all the impurities, so it’s good to know. Anyway, keep in mind that simmering won’t kill chemical contaminations. Also, always filter the cloudy liquid before boiling or cooking in it.

So how to purify it? The recipe is simple.

  • Pour the water to the bowl (skillet, etc.) and place it on high heat.
  • After the temperature is high and liquid starts rolling, let it steam and bubble for 2-3 min or longer. Like that, all the harmful bacteria will be killed for sure.
  • You can cover the tank with the lid or not – up to you.

Remember that if you go high in the mountains, the liquid will start simmering at a lower temperature due to the pressure changes. So let it simmer longer than usual 3 minutes.

The purified liquid must be kept cool in a tightly sealed tank. If it tastes “flat”, it’s best to pour it between two tanks to fix the taste.

Another way is to leave water exposed to direct sunlight in a transparent tank but it’s not the best option.

Microwave boiling

One of the alternative recipes is to simmer water in a microwave. 

Pour it in any suitable bowl you can find that will stand the microwaving. As an option, find a ceramic/glass tank that will withstand the heating temperature.

Add any microwave-safe object into the water (e.g. wooden chopstick, etc.) to help it bubble. Salt can help, too, so add it if you don’t mind salty liquid.

Heat water in short intervals (approximately 60 sec) stirring regularly. When the liquid is steaming, it’s already perfect.

Boil water at high altitude

When we move up from the sea level, the pressure changes and it takes water way less time to roll. That’s why boiling it at high altitude can be a bit tricky (mostly because it boils faster but remains hard to cook in it).

One of the easiest recipes in this situation is to follow simple steps.

  • At high altitude, due to another pressure, the liquid evaporates faster, so start with more water
  • Boil longer. If it normally takes 20 min or less, add 1 min of cooking per every 305 meters above sea level. If the normal cooking time is more than 20 min, add 2 min per 305 meters when being up from sea level
  • Go for a pressure cooker since it helps to get water simmered faster and better
  • Salt and other related methods will hardly work so don’t waste your time on those.

What Boiling Water Protects Us From?

Everyone knows that water needs to be boiled prior to drinking it, but did ever think of why exactly we must do it?

What is so harmful in this liquid that can make us purify it? Or is it just for increasing its quality?

Of course, if we live in a city with a well-developed infrastructure, boiling water is not needed for purifying it. We can simply buy already filtered liquid and boil it only to make some tea since it won’t brew otherwise.

However, boiling for purifying is still needed in places and situations where we can’t reach for the clean water so simply.

  • when we are hiking
  • when we are on a camping trip
  • if we live in a distant place with no or very poor infrastructure
  • when we are traveling and can’t buy water anytime we need it
  • in case of a natural disaster and damage to the infrastructure

In most of these cases, safe drinking is a must since impure water can cause multiple health issues from light nausea to stomach pains, vomiting, diarrhea, and dehydration. 

If we drink water from a stream, it can be contaminated by different impurities, but even old pipes can be dangerous, especially if they were not checked regularly and harmful flora had enough time to grow there. Add chemical spills and industrial runoffs, and you will get the complete picture.

Experts Say
Dr. Troy Madsen
Tenured Associate Professor in the Department of Surgery, Division of Emergency Medicine
I don't see it a lot, and it's probably because I think the risk is not really high, but the risk is there. It certainly is there, and the big thing we're worrying about is Giardia.

If you ever are out hiking or backpacking, the best to have is just carry some iodine tablets. I like to do some trail running, and just in the little handheld water bottle I carry, I've got a little packet with a couple of iodine tablets because I figure if I'm out somewhere in the mountains and there's a water source there, but I'm too far away to really refill my bottle and I need some water, that's some option.

So what so harmful can “dwell” in this liquid? In fact, it can be anything from living microorganisms to dangerous chemicals that got into the stream from plants or factories.

  1.  Bacteria 
  2. Viruses
  3. Parasites (f.ex Giardia)
  4. Metals e.g. iron, lead, or mercury
  5. Chemicals e.g. pesticides or herbicides
  6.  Pharmaceuticals

All these factors can turn water from being safe to an extremely health-hazardous liquid.

Can Boiling Kill Any Threat In Water?

It is a common belief that boiling destroys any harmful additives and inclusions it has. However, it is not quite true. 

Organic threats like bacteria, parasites, or viruses can be destroyed by bringing water to the boiling point. But chemicals and metals won’t be affected by heating that much leaving the liquid still harmful.

So what shall we do?

In this case, to make sure that the water you’re going to consume is absolutely safe, it would be more preferable to use another way of purifying it.

Chlorine bleach

It may sound terrifying but adding this product to water will kill the germs for sure. Add only a quarter of a teaspoonful of bleach per one gallon of liquid and let it sit for half an hour. – as EPA says. Then it can be consumed safely.

Purifying tablets

These chlorine or iodine tablets is a staple when hiking or camping.

Filters

Small and portable, they will protect water from germs and other harmful additives like chemicals or even microplastics. You can find filters for drinking bottles or for drinking directly from a river or a stream. There are even special purification systems for camping!

Boil It Right

You might be surprised but to make water safe to drink,  we need to boil it correctly.

For doing everything right, remember what steps to take to make it consumable.

  • Place a kettle or a pot over the burner’s fire and turn it on to a high or medium-high heat
  • Wait for the content to start rolling boil (that’s when big bubbles appear)
  • Let the water boil like this for 60 sec. To be completely sure that it is safe, you can let it boil for two more minutes (3 min in total)

The only issue about this boiled water is that it often tastes flat, but that can be easily fixed.

Simply pour it there and back between two tanks (pots or mugs) to let it get more air in.
