Both serve the same purpose but one is cheaper

Many households, for convenience, are using the electric airpot. But, it would cost about $20 to $25 per month for boiling water and keeping the boiled water warm.



To reduce electricity consumption further, you may like to boil the water using a normal 3-litre water kettle that comes with a whistle for safety and a 3-litre thermos flask to store the hot water. The thermos flask you see in the picture on the right costs just S$28. With this combination, you could save easily S$15 to S$20 per month.
