- Almost no household lacks electric kettles as energy-saving everyday helpers.
- The downside: Many products are made of plastic.
- We have compiled a list of good, harmless boilers in stainless steel and glass, such as those from Bosch or Philips, which also impress with their great design.
Boiler in stainless steel
Aki’s cauldron
Since stainless steel as a material has a very neutral and tasteful design, it is not difficult to find nice kettles made of this material. It is important that not only the housing is made of metal, but above all the interior of the boiler.

Many models have plastic lids. Here it is important to ensure that the plastic used is absolutely BPA-free, i.e. without the contaminant bisphenol A, which is found in plastic. In addition, the lid should not be in direct contact with the water during heating, but only catch the condensed water. The Akis kettle is a real designer piece and brightens up any kitchen with its rainbow colours.
BOSCH Boiler Styline TWK8613P
The Bosch Styline TWK8613P is also one of the harmless stainless steel boilers, which was also listed among the winners of the Öko-Test Foundation (2015). The stove also has a heating element covered with stainless steel, practical temperature selection, automatic switch-off and keep-warm function.

Ottoni Fabbrica Alice Elegance kettle
You play safe with boilers that have been processed completely without plastic, such as the Ottoni Fabbrica with an internal container made entirely of stainless steel. Even the removable limescale filter is made entirely of stainless steel. With a price of over 90 euros, the Italian-made model is not the cheapest, but it is certainly one of the healthiest. And with its retro-style kettle design, it looks smart in any kitchen. It has a capacity of 1.7 liters.
monzana electric kettle in retro design
A slightly cheaper variant is the model from the company monzana, also in the cordless tea kettle look. The kitchen helper is equipped with a water level indicator, removable filter, automatic shut-off and overheating protection, and its large opening makes it easy to pour in and out.
Arendo electric kettle
The baby kettle with a capacity of 0.5 liters from Reer is impressive as a travel kettle or as a kitchen appliance for a single household. The mini boiler is fast, energy-saving, switches off automatically and is made of stainless steel. The parts made of plastic have been labeled as BPA-free.

Glass is a completely harmless and food-safe material. In addition to the health aspect, glass stoves are particularly impressive because of their appearance. An additional eye-catcher is created when LED lighting is attached to the bottom of the unit, as for example with the glass kettle from TZS First Austria.
WMF kettle glass LONO
Most models are made from a combination of glass and stainless steel, like WMF’s Lono kettle. With 3,000 watts, the wireless model has a very high output and is made of heat-resistant, stable and tasteless Schott Duran glass. The lime water filter is also removable and therefore easy to clean, but made of plastic. According to the manufacturer, the kettle’s plastic components are BPA-free.
ProfiCook tea kettle made of glass
The ProfiCook WKS1020G model is a trendy 2-in-1 glass and tea kettle, also made of heat-resistant glass. With an additional stainless steel tea filter that can be raised and lowered, the wireless device not only allows you to quickly prepare hot water, but also fresh tea at the desired temperature. In addition to the temperature display, the modern glass stove has a quick start and keep-warm function as well as dry-running and overheating protection. Up to 1.7 liters can be heated at once.
