I bet your kitchen faucet does not offer you boiling hot water. Don’t get me wrong. I can get hot water to clean the dishes but making tea with it is a no no. The GROHE red system keeps three liters of filtered kettle hot water, so you can prepare your tea or whatever else you are having faster.
This is great for making tea or coffee instantly. Just make sure you don’t burn yourself, though I doubt that’s going to be an issue with this design. What do you think? Great idea or what?
