You always have boiling water at hand right away with a Quooker system. That way, you can make a cup of tea or fill a large pot with boiling water right away. That way, your potatoes, rice, and vegetables will boil almost instantly. If you want more flexibility, get a Quooker Flex faucet. It has a pull-out hose, so you can easily rinse all corners of your sink. Have to wait a long time for warm water in your kitchen, for example? Choose a COMBI+ reservoir.
