Can You Use A Coffee Maker To Boil Water – You Should Know

Most people like their coffee served hot. Coffee machines mainly use hot water, but do they boil the water? Can you use a coffee maker to boil water? And what are the pros and cons?

If they use to boil water, how do they boil the water, or do you use already boiled water? I want us to find out the perfect water temperature for a coffee maker. Let’s find out more about coffee makers.

Boiling water is that water that has heated up to its boiling point, usually 100 degrees at room temperature. At boiling point, there is the rapid vaporization of water as it transitions state to form water vapor. When water is boiling, bubbles usually appear on the surface before it reaches the boiling point.

What Would Happen if Coffee Makers Used Boiling Water?

Coffee makers can use boiling water, but it does not result in good taste of the cup of coffee. Preferably, you could use a stovetop coffee maker and would realize that it burns the dripping coffee grounds. The high boiling water temperature heats the coffee grounds, making it taste bitter. This bitterness in the coffee-taste makes most people avoid boiling water.

What Are The Advantages Of Using A Coffee Maker For Hot Water?

Using a coffee maker gives you hot water that you need for most of your brewing. Using a coffee maker gives you instant coffee, health benefits, and gives you a good taste in your coffee cup. In comparison to buying coffee from coffee shops, using a coffee maker is cost-efficient. A coffee maker also sterilizes items and gives you high-quality coffee that suits your health benefit needs. The coffee maker uses water below the boiling point that suits most of your needs.

What Are the Disadvantages of using Coffee Maker for Hot Water?

The coffee maker has restricted items it can sterilize. You have to ensure that you rinse your coffee maker properly when sterilizing something for a baby or sterilizing pacifiers to remove caffeine. Caffeine is known to cause nightmares in kids, hence unhealthy. Using hot water also dissolves the components in the metals of your coffee maker, making your coffee maker lose efficiency over time.

How Do Coffee Makers Heat Water?

Coffee makers heat water through an aluminum or copper heating coil. This machine brings water down through gravity and heats it to boiling temperature. As water is boiling, steam rises through the tube on the upper side. This steam bubbles rise and condense back into hot water at the showerhead.

Coffee makers apply steam pressure and thermo-expansion, which are physic concepts. The bubbles that are forming around the coil push the already condensed hot-water bubbles further up. This steam drives the water vapor to the output tube.

These steam bubbles condense at the top of the output tube, before dripping. This dripping water is usually not at boiling temperature due to factors such as the type of machine and altitude. People living on higher elevations will get higher temperatures than those living on low altitudes.

When You Will Need Boiling Water

A coffee maker will not give you boiling water unless using it at a negative altitude in relation to sea level. If you want to sterilize something, you will require boiling water. Sterilizing things using a coffee maker is not recommendable. Unless properly cleaned, the remaining caffeine in the coffee maker machine can contaminate what you want to sterilize.

Using a coffee maker to boil water has its specifications, depending on altitude and time. If you want water at boiling temperature, you will have to use an electric kettle. An electric kettle can boil water, store it in a French press, and you can later pour it on your coffee dripper. 

What is the recommended Water Temperature for Coffee Makers?

The coffee maker starts pumping water out before it adequately heats up on the outlet tube. Generally, the coffee maker reaches a temperature of 195-205 degrees Fahrenheit. This 195-205 degree is the temperature range recommended by the National Coffee Association for coffee maker machines. The SCAA-certified coffee makers have a recommended temperature range at brew time. 

This temperature range is ideal for making coffee unless you want slightly higher temperatures. Note that the recommended ideal water temperature for a coffee maker reduces as you continue using it. Thermocouples control the perfect temperature for your brewed coffee using. A stopover coffee maker gives you slightly higher temperatures.

Can You Put Boiling Water in a Coffee Maker?

Stovetop coffee makers can use boiling water since the closed chambers heat up quickly. However, when using hot water, you need to be extremely careful since the dripping coffee grounds are just above the water chamber. The water in the coffee maker heats up so quickly and can boil over to the top. The pressure building up in the coffee maker pushes the water out of the outlet preventing it from bursting.

Coffee Maker Does Not Boil Water to Make Coffee, Why?

A coffee maker gives you hot water suitable for use for most of your needs. However, it is not the best way to achieve boiling water temperatures. First, boiling water is not ideal for brewing coffee since it results in a bitter taste. Coffee made from boiling water, when left unchecked, can start evaporating and thus reduce.

A coffee maker will have to boil all the water and turn it to steam. Most coffee maker designs cannot boil all the water above the boiling point. Also, trapping the steam and maintain that boiling temperature requires the incorporation of another device. Most coffee makers have separate hot-water dispensers that can heat the water to boiling temperatures.


In conclusion, this article goes into depth on the query-can you use a coffee maker to boil water. A coffee maker has both pros and cons for brewers. However, the coffee makers cannot achieve a boiling point. Recommended coffee makers have an ideal temperature range, slightly below the boiling point.
