What type of insulation is recommended for heating a pool?

Rigid foam insulation panels are recommended for heating a pool due to their high insulating properties and effectiveness in minimizing heat loss. These panels are specifically designed to resist moisture and provide superior thermal resistance, making them ideal for use in environments that are exposed to water and humidity, such as around a swimming pool.

Unlike other types of insulation, rigid foam panels create a robust barrier against both heat loss and water infiltration. Their structural integrity allows them to maintain performance over time even when subjected to temperature fluctuations and damp conditions. This makes them particularly suitable for pool settings where maintaining water temperature is crucial for user comfort and reducing heating costs.

In contrast, options like fiberglass insulation may become less effective if they absorb moisture, while blown cellulose could settle over time and lose insulating efficiency. Standard wall insulation is not suited for pool environments as it typically does not provide the necessary resistance to moisture and thermal transfer required to maintain high efficiency levels in such applications. Thus, rigid foam insulation panels stand out as the most appropriate choice for effectively heating a pool.
