Compact instantaneous water heater for wash basins and kitchen sinks. The connected load is 6.6 to 8.8 kW 220 to 240 V. This means that the instantaneous water heater has enough power to heat around 5 l/min of warm water to 35 °C to 55 °C. In many countries, cold water is warmer than in Germany, so the unusually low power for local conditions is sufficient for showering. During installation, the instantaneous water heater can be limited to 6.6 kW. This makes the compact instantaneous water heater versatile and, with the IES® heating technology, sets new standards in terms of fast and efficient water heating.
