How to choose the best instant hot water tap for you

Depending on the size of your household or the size of your kitchen will determine what instant hot water tap is right for you. Here are some things to consider when browsing.

Different types of taps

Two-in-one taps (2-in-1): dispenses boiling and cold water

Three-in-one taps (3-in-1): dispenses boiling water as well as hot and cold water

Four-in-one taps (4-in-1): dispenses boiling water, on-demand cold filtered and standard hot and cold water.

Tank size

Tank capacity needs to be right not only for your family's boiling water needs but also for the space you have under your sink. Usually, tanks come in 2L, 3L or 4L. Unless you need lots of water from your tap at once regularly, one of the smaller tanks should do the trick.

Water pressure

The water pressure must be sufficient in your home for a boiling water tap to run efficiently. The taps will need a minimum of one bar of pressure, but you can check the water pressure of your own home by installing or purchasing any fixtures.

Safety functions

If you have children, look out for taps with childproof handles and insulated sides that remain cool even when boiling water is flowing.

FAQs

What are the advantages of instant hot water taps?

Cost-effective: If you find yourself pouring brews several times a day at an average cost of 2.5p per boil, this secretly adds up over time. Some instant boiling water taps claim that it costs only 3p to run the tap per day, making it a cost-effective option for hot drink lovers. And if you really want to stack up the savings, consider a mug warmer to keep your favourite hot beverage drinkable for longer, and perhaps a reusable coffee cup so you can take your brew of choice with you and save on takeaway drinks.

Reduces water waste: It is sometimes tricky to guess how much water you need to put in your kitchen kettle to make teas or coffees. However, as you're only pouring what you need into your cup, you will not have the same issues as overfilling your kettle.

Frees up kitchen countertop space: You can make more room on your kitchen work surface by removing a kettle and replacing it with an instant boiling water tap - no more rogue cables. Hot water taps allow for more room for meal preparation and other appliances.

Filtration technology: All hot water taps come equipped with a tap water filter system ensuring you get clean, limescale-free water every time. Like a kettle filter, you will need to change the filter around every six months.

Child-proof safety lock: A security lock is a prerequisite of most boiling water taps, making it a safe fixture to install if you have children. There is usually a hold, trigger, or sensor that activates the hot water, making this a much safer alternative than people realise.

Fast and easy to use: Think of an instant water tap as the ultimate upgrade to a kettle. You can dispense boiling water for your pasta, rice, and vegetables in seconds. The fixtures often have functions beyond just hot water and disperse filtered cold water and regular water functions. Additionally, people who have problems filling, lifting and pouring a standard kettle may find a hot water tap easier to use.

Hot water or boiling water?

When it comes to hot water taps, what's counted as boiling water can actually differ from model to model. Often, instant boiling taps actually come in a little lower than boiling temperature, making them ideal for use in hot drinks such as tea. True boiling taps are fantastic for getting the grime out of difficult dishes, so be sure to keep an eye out if you prefer the cleaning aspect. In practice, there's little difference between the two, with only a couple of degrees off each other most of the time.
