Boiling Water Taps Buyer's Guide: Which Brewmaster Instant Hot Water Tap Is Right for Your Kitchen?

Thinking about ditching the kettle? You're not alone. Instant boiling water taps have gone from luxury kitchen showpiece to one of the most requested upgrades in UK kitchens — and with the Brewmaster range now available at Essential Bathrooms with delivery within 48 hours, there's never been a better time. This guide walks you through everything you need to know before you buy: how boiling water taps work, the difference between 3-in-1 and 4-in-1 models, which spout shape and tank to choose, and the add-ons worth considering.

What is a boiling water tap and how does it work?

A boiling water tap looks much like a regular kitchen mixer, but alongside your standard hot and cold supply it delivers water at up to 98°C on demand — hot enough for tea, coffee, pasta, stock, sterilising and more. The magic happens under the sink: a compact insulated tank (think of it as a very well-lagged mini boiler) keeps a reserve of water at temperature, so there's no waiting for a kettle to rumble through its cycle. You simply engage the safety handle and pour.

Because the tank only heats the water it holds — and keeps it hot very efficiently — a boiling water tap typically wastes far less water and energy than repeatedly overfilling and reboiling a kettle. You also win back worktop space, which in most kitchens is worth the upgrade on its own.

3-in-1 vs 4-in-1: what's the difference?

This is the first decision to make, and it's simpler than it sounds.

A 3-in-1 tap gives you three water types from one tap: standard hot, standard cold, and instant boiling hot water. The Brewmaster 3-in-1 Square and 3-in-1 Swan are the most affordable route into instant boiling water and perfect if you're happy with your current drinking water arrangements.

A 4-in-1 tap adds a fourth output: filtered cold drinking water, run through a dedicated filter so it tastes noticeably cleaner than straight tap water. If your household gets through bottled water, a 4-in-1 pays for itself in convenience alone — no more lugging multipacks home or cluttering the fridge. See the Brewmaster 4-in-1 Square and 4-in-1 Swan.

Square, swan or pull-down: choosing your style

Brewmaster taps come in three profiles, all in solid brass:

• Square — crisp, angular lines that suit modern, minimalist and handleless kitchens. If your kitchen leans contemporary, this is the one.
• Swan — a graceful curved neck that works beautifully in both classic and modern settings, with generous clearance for filling tall pots and vases.
• Swan Pull-Down — the Brewmaster 4-in-1 Swan Pull-Down adds a flexible pull-down spray head to the swan profile, ideal for rinsing the sink, washing veg and reaching every corner of a big Belfast basin.

Pick your finish

The 4-in-1 range comes in six premium finishes — Chrome, Brushed Nickel, Gunmetal, Brushed Copper, Brushed Gold and Matt Black — so there's a match for every sink, handle and appliance scheme. The 3-in-1 range keeps it classic with Chrome, Brushed Nickel and Matt Black. Brushed finishes are particularly forgiving of fingerprints and water spots, while Matt Black and Brushed Gold make a striking statement against light worktops.

Choosing your tank: standard, digital, or 4 litre PRO

Every Brewmaster tap comes with its under-sink tank included — but you have choices:

• Standard tank (3-in-1 models) — a compact 2.4 litre tank measuring just W178 × D250 × H262mm, leaving plenty of cupboard space.
• Digital tank — the same compact 2.4 litre footprint with a digital temperature display, giving you visibility and control over your hot water.
• 4 litre digital tank (PRO) — available on the 4-in-1 range, this larger-capacity tank (W197 × D299.5 × H272.5mm) delivers more boiling water between reheats. Busy family kitchen? Serial entertainer? Go PRO.

Already own a Brewmaster and want more capacity? The 4 Litre Tank is available separately as an upgrade or replacement.

Fancy chilled water too? Add a chiller tank

Here's the upgrade most people don't know exists: pair any Brewmaster 4-in-1 tap with the Brewmaster Chiller Tank and your filtered water comes out properly chilled — fridge-cold, straight from the tap. It installs under the sink alongside your hot tank and comes in three sizes (Standard, 1.5 litre and 2 litre). Between 98°C boiling and chilled filtered water, you've essentially got a café-grade water station in your kitchen.

Are boiling water taps safe?

Much safer than a kettle, in practice. Every Brewmaster tap uses a child-safe handle on the boiling outlet — it must be deliberately engaged, so there's no accidental scald risk from a knocked kettle or trailing flex. The whole range is WRAS approved (the UK benchmark for water fittings), built in solid brass, and backed by a 2 year guarantee.

Installation

Installation is straightforward for any competent plumber or kitchen fitter: the tap mounts in a standard tap hole, the tank sits in the cupboard below connected to your cold feed and a power socket, and fixings are supplied. Full fitting instructions and technical datasheets are available to download on every product page.

Quick answers

Does it really replace the kettle? Yes — 98°C water on demand covers tea, coffee, cooking and sterilising. Most owners never look back.

Which tank size do I need? The 2.4 litre tank suits most households. Choose the 4 litre PRO if you regularly make multiple hot drinks back-to-back or cook for a crowd.

Can I get filtered water without the boiling function? The 4-in-1 gives you both — filtered cold and instant boiling — from one tap, which is the point: one tap, every water you need.

How quickly can I get one? All Brewmaster products are delivered within 48 hours.
