FAQs

Find answers to our customers' commonly asked questions.

A 4-in-1 tap offers four different water settings:

  1. Regular hot water
  2. Regular cold water
  3. Filtered boiling water
  4. Filtered cold water

4-in-1 taps are therefore ideal for kitchens in contemporary homes, offering unbeatable convenience and comfort, plus a superior-quality finish.

A boiling water tap works in partnership with an electric-powered boiler unit (tank). This boiler unit draws in water from the regular mains supply, heats and stores it at a designated temperature, and then releases it instantly when the boiling water function is activated on the tap handle. After use it refills to full capacity and heats up to the designated temperature again. Our standard tanks hold 2.4 litres - enough for 6-7 cups of boiling water. For larger households, you can upgrade your tank capacity to 4 litres for just £99.

Our taps are designed to be inherently cost-effective to run. With insulated materials and energy-efficient tech, we ensure that you won't be paying over the odds. In fact, in some situations our boiling water taps are more energy-efficient than traditional kettles, costing just 10-15p per day to run versus the 3-4p per boil of a kettle.

Our taps are straightforward to install, requiring basic plumbing knowledge and tools. Everything else is provided, including a range of videos to demonstrate how to install your new tap, making the installation process straightforward. If you are unsure, we recommend hiring a plumber to manage the installation - it should only take an hour or so if done correctly. Our team is also on hand to answer any questions you might have about the process.
