The hot water dispenser is especially popular with our kids. We are a 6-person household and everyone has a different taste of tea. We also have morning different times when we go out of the house. When the tea was too hot the first, he was the last almost too cold. Therefore remained of a teapot boiled often a lot of tea left. This problem is completely solved with the hot water dispenser. Since about 2 months he has been working with us, is easy to use and to fill up the demountable tanks we take often times the old teapot ago, for our smallest is easier than running to the tank for water tanks. Since the preparation of a fresh tea has now become much easier with the device, the tea consumption has increased significantly in the meantime. However, the device showed after 4 weeks already that the water filter should be changed. That was us just a little too early. On the used Britax Maxtra filters we have experience for years. They last longer and are only after a water volume of about 100 to 120 l worse in its filtering function (water hardness 16-17). After rebooting with the "old" filter but it went further problems. For technological reasons, the first 5-10 ml of water from the device are still cold, before the water runs out of the device at the selected temperature. At 100 ° C teas you should be first passed through a glass of water (that warms the cup to), stop, then throw away the broken-in water and again press Start. Otherwise, the tea has more than 85 ° C during brewing.
