Use of a heat exchanger to recover energy and reuse heat from drain water
Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery,[citation needed] or sometimes shower water heat recovery[citation needed]) is the use of a heat exchanger to recover energy and reuse heat from drain water from various activities such as dish-washing, clothes washing and especially showers. The technology is used to reduce primary energy consumption for water heating.
