Most Astini models also include an under-cabinet filter system. This filter must be mounted vertically near the boiler unit, with sufficient space for easy cartridge replacement. The filter cartridge helps protect the heating tank from scale build-up and improves water quality — an essential part of maintaining reliable instant boiling water performance.

The under-sink boiler should be installed in a ventilated cupboard with clear access to the filter or digital control display (where fitted, such as on the HotStream 3.0). Always use isolation valves to simplify maintenance or future servicing.

Professional installation is recommended for all Astini boiling water taps, particularly 4-in-1 models with integrated filter kits. Correct fitting ensures optimal efficiency, preserves your Astini warranty, and guarantees consistent boiling water on demand.

All Astini boiling water taps are supplied with an under-cabinet water filter, which plays a key role in protecting the boiling tank and maintaining overall performance. The filter reduces limescale, removes impurities, and ensures the system continues to produce clean, safe instant boiling water every time you use it.

To keep your tap operating efficiently and to maintain your Astini warranty, the filter cartridge must be replaced every 3 to 6 months. Replacement frequency depends on your local water hardness and household usage. Failure to change the filter within this interval can cause scale build-up, reduced flow, and invalidate the manufacturer’s warranty.

When replacing the filter:

• Mount the new cartridge in the same vertical position under the sink.

• Check all connections for leaks before restarting the system.

• Run water through the tap for several seconds to flush out any trapped air or fine carbon particles.

• Only use genuine Astini filter cartridges to maintain full compatibility and warranty coverage.

The under-sink boiler unit itself is largely maintenance-free, but it should remain upright, dry, and accessible for future servicing. Periodically wipe the tap and tank connections with a damp cloth to prevent dust and residue build-up.

Routine filter changes and occasional inspection will keep your Astini boiling water tap performing reliably, energy-efficiently, and within its manufacturer’s warranty conditions.

Astini kettle taps offer a practical and affordable way to add instant boiling water functionality to your kitchen. Like any appliance, they come with both advantages and limitations depending on your setup and usage.

Selecting the right Astini boiling water tap depends on how you use your kitchen, the space available, and the look you want to achieve. Each model in the Astini kettle tap range offers different benefits, so consider these points before buying:

1. Functionality – Decide between a 3-in-1 tap (hot, cold, boiling) or a 4-in-1 tap (adds filtered cold water). If you drink a lot of filtered water, the 4-in-1 is worth the upgrade.

2. Space – Check your under-sink cupboard for enough room to fit the boiler tank and filter system comfortably, with access for maintenance.

3. Finish & Style – Match your tap finish to your kitchen décor. Chrome suits modern kitchens, while brushed brass and black work well in traditional or industrial settings.

4. Usage & Household Size – For busy homes or frequent cooking, choose a model with a larger tank capacity such as the HotStream 3.0. Smaller households may prefer compact options like the Bollitore² 3-in-1.

5. Budget & Features – Compare price and performance. Digital models like the HotStream offer extra convenience, while the Bollitore² range provides excellent value without unnecessary complexity.

Whichever model you choose, every Astini boiling water tap delivers reliable performance, modern design, and the practicality of instant boiling water at your fingertips.

The Astini boiling water tap range combines modern design, everyday convenience, and strong value for money. Each model — from the Bollitore² and HotStream to the Industrial and Grande — delivers instant boiling water alongside standard hot and cold functions, helping you save time and reduce energy use.

If you’re upgrading your kitchen, an Astini kettle tap offers a neat, efficient alternative to a traditional kettle, with easy under-sink installation and a full filter system included. Regular filter changes every 3–6 months keep performance consistent and protect your manufacturer’s warranty.

Bring speed, style, and convenience to your kitchen with an Astini boiling water tap. Explore the full range to compare designs, finishes, and features that suit your space — all supplied with an under-sink boiler and filter kit ready for installation.
