System for preparing hot water, has undivided and buffer tank-free connecting line provided between system input and output, where vaporous primary medium is available in sufficient amount such that liquid is heated to certain temperature

摘要

The system (2) has a system input (10) and a heat exchanger (30) configured such that a vaporous primary medium i.e. water vapor, having temperature equal or above a boiling point is entered into the heat exchanger and partially condensed in the heat exchanger. The vaporous primary medium is available in sufficient amount such that liquid is heated to temperature corresponding to the boiling point of the vaporous primary medium or is lower than the boiling point. An undivided and buffer tank-free connecting line is provided between another system input (4) and a system output (38). An independent claim is also included for a method for preparing warm liquid.
