Boiling Water Tap Reviews

QETTLE 4-in-1 (Editor’s Choice)

The first on our list is the QETTLE 4-in-1. It is our first choice for several reasons.

It is the prime choice for your new boiling water tap. Other boiling water taps dispense water at 98 degrees celsius, but this tap manages to dispense at 100! The 2 degrees do make the difference between very hot and boiling water.

We have chosen the QETTLE 4-in-1 as the best instant hot water tap due to the unbeatable high temperature, the product’s impressive safety features, and efficiency.

Dealing with hot temperatures can be dangerous, so using the tap with caution is important. QETTLE has implemented safety features such as a safety clip. This clip will stop anyone from using the tap, and only when it is removed can you retrieve the hot water. To make the tap even safer, especially if you have children in the house, you must press the button on the handle simultaneously by turning the handle clockwise. This 2-stage safety will help protect young ones and ensure that only capable adults use the hot tap.

With the QETTLE tap, you can fill up to 4 cups of boiling water at one time. The boiler tank is the perfect size to fit under your countertop without taking up too much space. The tank size is 223mm x 170mm x 293mm, and the tank capacity is two litres. You can trust this tap to be a quality addition to your kitchen, fully approved and insulated.

There is also a filtered water system integrated. This reduces limescale build-up chances and provides an unlimited flow of filtered cold water. In addition, the filter cartridge is easy to change and should be replaced every half a year. A handy LED light will indicate when the cartridge needs changing.

The safety cap may become faulty after a few months of use. Some people thought the filtration system was not brilliant. In a few instances, water was leaking from the tap, but this can usually be fixed.

  • Includes safety clip
  • Push-button and twist safety design
  • Large capacity


  • The safety cap may become faulty after some time

Bristan Rapid 3-in-1 (Luxury Choice)

The Bristan Rapid 3-in-1 is an excellent choice if you are looking for personalisation. 

This boiling water tap offers seven different temperatures so that you can set it to your desired temperature. The range heats up to 98 degrees celsius. The innovative safety features of the Bristan Rapid 3-in-1 include a push-button operation. This means that it will be difficult for young children to operate the tap, which will keep them safe from the hot water dispenser. The push-button and twist design is also made to flow smoothly. This will reduce the chance of ‘spitting’ from the tap, also reducing the chance of scalding.

Also, to protect you, the spout will remain cool to touch. This will be in effect even when the boiling water function is being used. When you turn off the tap, the boiling hot water in the spout will return to the tank, meaning that the spout will not retain hot water and heat the metal.

The Bristan Rapid 3-in-1 also features a space-saving compact design. Your cupboard space will be left mostly free for your other products because the 2.4-litre tank is optimally designed to store the water supply in the best way. This tank capacity will fill a large pan or fill six mugs – great for serving guests or cooking quickly.

If not installed correctly, you may experience leaking, so it is best to check that everything is properly installed before you use it. Also, some customers had problems with low pressure; however, you can get a two-year warranty with this boiling water tap to fix any problems!
