Are you noticing limescale buildup in your kettle? No matter how many times you clean it, it always seems to come back and you are looking for a solution? There are a wide variety of electric kettles currently on the market labelled as “limescale free kettle” or “anti limescale kettle”, but are they really worth it?
We will be taking a deep dive into the different models and brands offered and what their differences are to judge which one is the best kettle for hard water.
Can a kettle be limescale free or is it a combination of different factors? Being made primarily of glass helps prevent the formation of limescale since glass is generally much less porous (presence of tiny holes that make it easier for limescale to “grow”) than plastic. The second is the presence of an integrated filter or filter kettle to avoid limescale present in the water from ever coming in contact with the heating element and the electric kettle.
Having a flat heating element instead of an immersion tubular heating element also reduces the rate of limescale growth in a kettle for the simple purpose that a flat heating element has more surface area with the water and thus it takes less time to boil water than an immersion heating element. Finally having a wide opening makes the kettle much easier to clean and increases aeration which prevents limescale or calcium deposits from forming inside the kettle.
