A heat exchanger in a pool heater is the component responsible for transferring heat from a heating source (such as gas, propane, or electricity) to the pool water. Here’s how it works:

  1. Heating Source Interaction: In most pool heaters, water or air heated by gas or electric elements flows through one side of the heat exchanger, heating it up.

  2. Heat Transfer: Pool water circulates through the other side of the heat exchanger. As it passes over the heated surface, heat transfers from the exchanger to the pool water without the two fluids ever directly mixing.

  3. Materials: To maximize efficiency and resist corrosion, heat exchangers are often made from durable materials like copper, titanium, or stainless steel. Titanium is particularly popular in saltwater pools due to its excellent corrosion resistance.

  4. Efficiency: A high-quality heat exchanger can significantly increase heating efficiency by optimizing heat transfer, resulting in faster heating times and lower energy use.
