Instantaneous water heating principle

The instantaneous water heating principle is a hygienic way of heating DHW. Firstly, cold drinking water flows into one side of a plate heat exchanger. At the same time, hot water from the buffer cylinder flows through the other side of the plate heat exchanger. As these two streams of water are kept separate by the copper or stainless steel plates used in the plate heat exchanger, the drinking water is heated but not contaminated.
