Pools heated to more than 90 degrees F shall have a pool cover with a minimum R value of what?

The correct answer is: 12

For pools heated to more than 90 degrees Fahrenheit, the requirement for a pool cover with a minimum R value of 12 is based on guidelines aimed at managing heat loss and ensuring energy efficiency. The R value measures the thermal resistance of the cover, meaning that a higher R value indicates better insulating properties. An R value of 12 is significant because it effectively reduces heat loss, which is crucial for maintaining the temperature of swimming pools in warmer conditions. This not only assists in energy preservation but also contributes to keeping operational costs down, as less energy is required to heat the pool water. In comparison, R values lower than 12 may not be adequate for such temperatures, potentially resulting in greater energy consumption and discomfort for users who prefer warmer water. Therefore, choosing a cover with an R value of 12 ensures compliance with the regulations and promotes more sustainable pool management practices.
