How to Install a Boiling Water Tap
Boiling water taps have become a must-have in modern kitchens, giving you instant 98°C hot water for tea, coffee, cooking, and cleaning - all without waiting for the kettle. If you're upgrading your kitchen with one of our boiling water taps, the installation process is easier than you might think. Whether you're a confident DIYer or prefer a professional touch, this guide will walk you through every step.
A boiling water tap isn't just about convenience - it's about transforming your kitchen routine. Here's what you gain:
- Instant boiling water at your fingertips.
- Energy efficiency, as you only heat what you use.
- Streamlined design that replaces your kettle and clears counter space.
- Built-in filtration for cleaner, better-tasting water.
- Safety features, like child-lock systems to prevent accidental use.
At Xiamen Smart Water Technology Co., Ltd., we manufacture 3-in-1 and 4-in-1 boiling water taps trusted by top international brands.
Before starting, make sure you have:
- Adjustable wrench and screwdriver
- Bucket or container (to catch water)
- Drill (if you need to create a new hole in your sink)
- A plug socket under your sink
- Access to your water mains
If you're missing any of these, don't worry - a professional plumber can handle the entire installation for you.
Step 1: Turn Off the Water Supply
Start by turning off your main water supply. This prevents leaks or accidental spills during installation.
Step 2: Measure and Prepare the Space
Each boiling water tap comes with a compact boiler tank that fits neatly under your sink. Before installation, measure the cabinet space to ensure a proper fit.
Boiler and Filter Dimensions:
| Component | Height (mm) | Width (mm) | Depth (mm) |
|---|---|---|---|
| Boiler Tank (2.4L) | 295 | 184 | 184 |
| Filter Cartridge | 295 | 84 | 84 |
Make sure the plug socket is safe and the surface is clean and dry.
Step 3: Prepare Your Sink Area
Remove the old tap, clear out the cupboard, and wipe everything down. Position the boiler tank within reach of the water feeds and socket - but don't plug it in yet.
Step 4: Install the Boiling Water Tap
Feed the tap's hot and cold hoses through the sink hole. Secure the tap using the supplied fittings. If you're unsure, a plumber can easily handle this step for you.
Step 5: Connect the Boiler and Filter
Attach the boiler to the filter and then connect them to the tap according to the manual. Tighten all fittings carefully to prevent leaks.
Step 6: Plug In and Test the System
Now plug in the boiler and turn your water supply back on.
Check the operating pressure - it should be between 0.5 and 5.0 bar. If your pressure is outside this range, pause installation and contact a plumber for advice.
Step 7: Let It Fill and Heat Up
Once connected, the boiler will fill and heat the water to 98°C in about 15 minutes. You can adjust the temperature between 75°C and 98°C using the digital touch screen on the boiler.
Step 8: Enjoy Instant Boiling Water!
You're all set! Your boiling water tap can now deliver up to 6–7 cups of hot water instantly, with only a 3–4 minute reheat time. Perfect for tea, pasta, or quick cleaning.
