The Quooker Fusion provides hot, cold and 100°C filtered boiling water from a single spout. Its high-vacuum insulation means that it only costs 3 pence a day to have boiling water at hand exactly when you want. This is the Fusion Round model which is beautifully finished in gold, it has a three litre water tank made of stainless steel and it can be converted to a 4-in-1 model with the addition of the optional Cold Water Filter kit. You can have peace of mind due to the childproof handle which needs to be double pushed and turned to activate boiling water. A light ring also illuminates red to indicate the boiling water tap is being used. This highly energy efficient tap is not only stunning to look at but very practical indeed.
