Best Instant Hot Water Taps for Kitchens

Instant hot water taps have quickly become an item that goes from being a luxury item for the kitchen to something that's actually very practical for everyday use. Are you fed up with waiting for the kettle to boil or looking for a solution to a cluttered kitchen countertop? Then investing in one of the best hot water taps for the kitchen can really make a difference for you.

But just how do hot water taps work, and are they really worth investing in? Well, let's find out!

 

How Do Instant Hot Water Taps Work?

Essentially, instant hot water taps come with a small boiler tank that's usually installed under the sink in the kitchen. The tank then boils the water at an extremely high temperature so that you get hot or boiling water the second you open the tap.

The tank then needs to be plugged into the electrical supply, so you'll need a socket nearby for it to work properly, as well as a water supply. Due to the complexity of these advanced taps, as well as the cost, it's usually best to use the manufacturer's installation service (if available) or hire a professional so that you know it's all installed correctly.

Are Instant Hot Water Taps Worth It?

First off, instant hot water taps can appear to be a costly option, especially compared to a simple kettle. Ultimately, whether they are worth the money depends on what matters the most in a kitchen. Below are some of the key benefits and what one ought to consider before making a purchase.

 

Pros

 

Energy-saving

 

Boiling a kettle can consume a lot of energy, especially if one wants a cup of hot water. With an instant hot water tap, one can have as much hot water as they need, hence saving energy in the long run.

 

Water-saving

Instead of boiling a kettle and then pouring the excess hot water, one can have a mug, pot, and jug of hot and cold water at their disposal. It may not sound like a lot, but this can save a lot of water in the long run.

 

Safety

All instant hot water taps are designed with a two-step mechanism that prevents children from getting burned.

 

Ease of use

Instant hot water taps are not cumbersome, and this makes them a perfect option, especially in a busy household and for the elderly.

Integrated filters

Among the features associated with the best instant hot water taps for kitchens are integrated filters, which are effective in purifying water and improving the quality and taste of drinking water.

 

Things to consider

 

Size of tank

The tank containing the water boiler is located inside the cabinet under the sink and can consume a considerable amount of space. It is therefore important to ensure you have sufficient cupboard space before purchasing.

Installation

Although instant hot water taps can be installed by the homeowner, they are more complicated than standard taps and therefore require installation by a professional.

Maintenance

Although the maintenance of instant hot water taps is easy, you may need a professional plumber if you notice leaks, low water pressure, or problems with the heating tank.

Extra filters and limescale removal

Replacement of the water filter may be necessary every six months, although this may vary depending on the type and quality of the filter. The filter may need more frequent replacement if you are living in a hard water area.

 

How We Test Hot Water Taps

In our bid to find the best instant hot water taps, we test them based on several criteria. Firstly, we test the flow rate by pouring a liter of water into a container, then measuring the time it takes to fill the container. The faster the flow rate, the higher the score.

We also test the water temperature by placing a temperature reader under the tap as the hot water is flowing. We then note the maximum average temperature reached, ensuring that the water is sufficient for our daily needs.

Another test is the splashing test, where we observe the amount of water that splashes as different items are filled with water, such as a standard mug with a tea bag, a mug with coffee, a travel mug, and a saucepan, all filled to a fixed height.

We also test the taste by allowing different people to take tea or coffee made with water from the tap, then vote on the taste. Lastly, we test the design, ease of use, instructions, and build quality.
