The tank combines an upper hot water section with 420 l and a lower buffer section with 200 l to a calculated total volume of 620 l.\u003c\/p\u003e \u003cp\u003eThe WK series is designed for systems where heating water is buffered and hot water is provided via a stainless steel corrugated pipe. This makes the WK 600 suitable for system setups where heat pump, hot water preparation, heating circuit control, and optional auxiliary heating are combined in one tank concept.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eIn the upper tank section, there is a stainless steel corrugated pipe heat exchanger with a heating surface of 9.5 m² and a maximum operating pressure of 10 bar.
