A Guide to Vented Water Boilers for Kitchen Taps
💧 How Do Vented Water Boilers for Kitchen Taps Work? (And Why You Might Want One)
If you’ve ever wished you could ditch the kettle and get piping hot water instantly from your tap, you’re not alone. That’s exactly what vented water boilers do and they’re becoming more and more popular in homes and workplaces across the UK.
But how do these clever little systems actually work? And what makes them different from regular hot water taps?
Let’s break it down.
🔥 What Is a Vented Water Boiler Tap?
A vented water boiler tap (also called an instant boiling water tap) gives you near-boiling water on demand, straight from your kitchen sink.
Unlike a regular tap that relies on your home’s main hot water system, this one is connected to its own mini boiler unit, usually installed under your sink. It heats and stores a small amount of water ready whenever you need it for tea, coffee, cooking, or cleaning.
⚙️ So, How Does It Work?
Here’s a simple, step-by-step breakdown of how vented boiling water taps do their thing:
1. Cold Water Comes In
The system connects to your cold mains water supply. When you draw hot water, the same amount of cold water automatically flows into the boiler tank.
2. It Heats the Water (Fast!)
An electric element inside the tank heats the water to around 98–100°C. The tank is well insulated, so the water stays hot without using too much energy.
3. The Vented Magic Happens
Now, here’s what makes it a vented system.
Because the Vettä 2.4L & 4L tank isn’t pressurised (unlike a Quooker or Qettle), any expanding steam or excess hot water vents safely—usually through the tap’s spout or a special outlet.
This means no pressure build-up, no leaks, and no need for extra plumbing gear like expansion valves.
4. You Get Instant Boiling Water
Turn the tap, with a safety button or twist handle—and instant hot water pours out.
As you use it, the tank refills and reheats, so you’re always stocked up.
🛠️ Why You Need a Special Tap
You can’t just hook this up to your standard kitchen tap. Vented boilers require a special vented tap, designed to safely handle steam release and prevent scalding. All Vettä models include child-safety locks. Check out our 4 in 1 range or 5 in 1 range with the addition of sparkling water
