What is the primary function of a heat exchanger in plumbing?

The primary function of a heat exchanger in plumbing is to transfer heat between two fluids without mixing them. This is achieved through the design of the heat exchanger, which typically involves a series of tubes or plates that allow one fluid to absorb heat from another fluid without the two coming into direct contact. This is essential in various plumbing applications, such as in heating systems where hot water is circulated to warm up cooler water, or in hydroponic systems where temperature regulation is crucial for plant growth.

By effectively allowing heat transfer while keeping the fluids separate, heat exchangers maintain system efficiency and contribute to energy conservation, making them a vital component in complex plumbing and heating systems.
