Instant hot water tap / Quooker tap.

Boiling water taps have gained significant popularity in recent years, revolutionising the way we access hot water in our kitchens.

These taps offer the convenience of instantly dispensing boiling water for a variety of purposes, from making tea or coffee to cooking pasta. However, like any technology, they come with their own set of advantages and disadvantages. In this article, we'll delve into the pros and cons of boiling water taps to help you decide whether they're the right choice for your kitchen


  1. Convenience: Perhaps the most significant advantage of boiling water taps is the unparalleled convenience they offer. With just a simple push of a button or flick of a lever, you can have piping hot water at your disposal within seconds. This eliminates the need to wait for a kettle to boil or to use a stove, saving you valuable time in the kitchen.

  2. Energy Efficiency: Boiling water taps are often more energy-efficient than traditional methods of boiling water. Unlike kettles or stovetops, which heat a large volume of water regardless of the amount needed, boiling water taps only heat the water that is dispensed. This can result in lower energy consumption and reduced utility bills over time.

  3. Space-saving: Installing a boiling water tap eliminates the need for a bulky kettle on your countertop, freeing up valuable space in your kitchen. This is particularly advantageous for smaller kitchens where space is at a premium.

  4. Safety: Boiling water taps are designed with safety features to prevent accidents, such as accidental scalding. Many models come with childproof locks or require a specific action, such as pressing and turning simultaneously, to dispense boiling water, reducing the risk of burns.

  5. Versatility: In addition to dispensing boiling water, many boiling water taps also offer options for delivering cold, filtered, or sparkling water, providing added versatility and convenience in the kitchen.


  1. Installation Costs: One of the primary drawbacks of boiling water taps is the initial cost of purchase and installation. Boiling water taps can be significantly more expensive than traditional kettles, and installing them may require modifications to your plumbing system, which can add to the overall cost.

  2. Maintenance Requirements: Boiling water taps require regular maintenance to ensure optimal performance and hygiene. Filters need to be replaced periodically, and the tank may need descaling to prevent the buildup of limescale. Failure to maintain the tap properly can result in decreased efficiency and potential health hazards.

  3. Limited Capacity: While boiling water taps offer instant hot water, they typically have a limited capacity compared to traditional kettles. This means that if you need to dispense large volumes of boiling water at once, such as for cooking pasta or filling a large pot, you may need to wait for the tap to reheat between uses.

  4. Potential for Water Wastage: Some users may find that they waste water when using boiling water taps, as it can take a few seconds for the hot water to start flowing. Additionally, if you accidentally dispense more water than you need, you cannot return it to the tank, resulting in wastage.

  5. Risk of Malfunction: Like any mechanical or electrical device, boiling water taps are susceptible to malfunction or breakdown over time. Components such as valves, seals, or heating elements may fail, requiring repairs or replacement, which can be costly and inconvenient.
