Â· just now. 1  I have measured the performance of two kettles; a plastic kettle with an exposed element and a stainless steel kettle with a concealed element. My findings were that the plastic kettle needed as much heat as an extra 130ml of water but the stainless steel kettle needed as much heat as an extra 250ml of water. The plastic kettle has a minimum water level at 500ml while the stainless steel kettle has a minimum water level of 600ml. Thus for a standard 220ml of water, I have to heat the equivalent of 630ml in the plastic kettle or 850ml in the stainless steel kettle. So the plastic kettle is 35% efficient for a single cup and the stainless steel kettle is 25% efficient. Filling the kettles above the minimum level with more than you need is also inefficient. If the kettle is not automatic, energy can be wasted before the kettle is turned off.
