Simplified installation thanks to bellows technology

Have you ever asked yourself, "Why do some hot water systems require a drain connection?"
That’s because traditional hot water tanks—like older Quooker models—use an overflow valve to discharge expansion water into the sewer. While this method works, it comes with a few drawbacks: potential leaks, tricky installations, and even unpleasant odors from open drain connections.
Enter: bellows technology.
Instead of relying on an open overflow system, Quooker’s new bellows technology uses a sealed, flexible metal expansion vessel. When the tank heats up and pressure increases, the vessel expands internally—no need for external drainage, no risk of sewer gas, and no extra plumbing hassles.

With this innovation, installing a Quooker COMBI+ has never been easier.

Here’s how bellows technology improves the installation process:
50% faster installation: Thanks to the simplified internal design, you can now get your COMBI+ up and running in half the time.
No drain connection needed: Forget drilling into your sewer lines or dealing with U-bends—this system is completely self-contained.
No risk of bad odors: Since there’s no open connection to the drain, you won’t have to worry about unpleasant smells creeping into your kitchen.
Enhanced safety: Fewer components and closed-loop engineering mean less chance of mechanical failure or leaks.
Backed by innovation: This isn’t just any feature—it’s the result of dedicated research from Quooker’s in-house R&D team, setting new standards in kitchen technology.

If you’re investing in a Quooker system, you’re clearly someone who values efficiency, quality, and long-term performance. Bellows technology supports those values by:

🌿 Saving you time and money on professional installation

🌟 Improving reliability and safety for your household

🔧 Reducing maintenance issues over the long term

🧩 Making your kitchen look and feel more streamlined—with fewer pipes, parts, and potential points of failure

Currently, this innovative feature is available in the Quooker COMBI+ system—our premium solution that provides boiling, hot, and cold water directly from a single tap. But that’s not all. If you’re planning a complete Quooker setup, consider enhancing your COMBI+ tank with complementary products like the Quooker Flex, which offers ultimate reach and flexibility; the Quooker Fusion, a stylish tap that delivers both form and function; Quooker Accessories such as soap dispensers and rosettes to complete your kitchen aesthetic; and the Quooker Cube Sets, which allow you to enjoy chilled and sparkling water straight from the same tap.

Absolutely. If you want a tap system that’s future-proof, easy to maintain, and engineered with precision, the Quooker COMBI+ with bellows technology is an unbeatable choice.

Whether you’re renovating your kitchen or simply upgrading your tap, this is your chance to experience the next evolution in kitchen convenience.

While professional installation is always recommended, bellows technology makes the process 50% faster and significantly easier, even for experienced DIYers.

Bellows technology is currently built into new Quooker COMBI+ models. If you have an older tank, we recommend exploring an upgrade.

At House of Kitchen, we believe that the smallest innovations often make the biggest difference. Bellows technology is a perfect example—it’s an invisible upgrade that transforms the entire Quooker installation experience into something faster, cleaner, and smarter.
