Electric kettles with plastic parts can leach harmful chemicals like BPA, phthalates, and endocrine disruptors into water
Electric kettles are a convenient and quick way to boil water, but some concerns have been raised about the potential health risks associated with certain types of kettles. One of the primary concerns is the presence of plastic parts in electric kettles, which can leach harmful chemicals into the water.
Plastic is known to contain chemicals such as BPA (bisphenol A), phthalates, and endocrine disruptors. When exposed to high temperatures, these chemicals can leach out of the plastic and into the water. BPA, for example, is known to disrupt hormones, which can lead to a range of health problems. Even ""BPA-free" kettles may still contain other harmful chemicals like BPS or BPF. Therefore, it is advisable to choose electric kettles with no plastic components, especially those that come into contact with boiling water.
Some electric kettles may also contain lead, a heavy metal that has been linked to various health issues. Lead can be found in the solder joints of some cheap kettles, and when exposed to hot water, it can leach into the water. This is particularly concerning as lead accumulation in the body can lead to serious health issues.
To avoid the potential risks associated with plastic and lead, consumers should opt for electric kettles made from alternative materials. Glass and stainless steel kettles are recommended as they are non-toxic and do not leach chemicals into the water. Stainless steel is a durable, lightweight, and affordable option that is suitable for various stove types. It is important to choose high-quality stainless steel with a chromium-to-nickel ratio of 18/8 or 18/10 to ensure food safety.
In addition to the potential risks posed by plastic and lead, it is worth noting that some older electric kettles with exposed elements may contribute to skin allergies through nickel leaching. While further research is needed, consumers who suffer from nickel allergies are advised to avoid purchasing new kettles with exposed elements.

Old-style electric kettles may worsen skin allergies through nickel leaching off exposed elements
Electric kettles are a staple in many kitchens, known for their convenience and speed. However, old-style electric kettles with exposed elements may pose a health risk by worsening skin allergies through nickel leaching.
The everyday habit of making a cup of tea with an electric kettle may have unintended consequences for your health, particularly if you are using an older model with exposed elements. The UK government has raised concerns about the potential link between elevated nickel levels in boiled water and worsened skin allergies. This issue predominantly affects those with nickel allergies, who may experience adverse reactions.
Nickel leaching occurs when nickel dissolves into the water from exposed elements in the kettle. The resulting liquid becomes more acidic, leading to higher concentrations of nickel. This is of particular concern for individuals with nickel allergies, as even small amounts of nickel can trigger a reaction. Symptoms of a nickel allergy include a rash or dermatitis, often on the hands, wrists, or neck.
To address this issue, the Food Standards Agency and the Drinking Water Inspectorate advise consumers with nickel allergies to avoid purchasing new kettles with exposed elements. Instead, opt for models with covered elements, typically found in the base of the kettle. This simple precaution can help prevent potential allergic reactions.
When choosing a new electric kettle, it is advisable to select one without plastic components, especially those that come into contact with boiling water. Non-toxic glass or stainless steel kettles are recommended to reduce the risk of harmful chemicals leaching into your water. Stainless steel kettles with a chromium-to-nickel ratio of 18/8 or 18/10 are certified as food safe and are a good choice to avoid nickel exposure.
