Pool Heat Time Formula:

Pool heat time refers to the amount of time required to heat a swimming pool to a desired temperature. The time it takes depends on several factors including the pool’s volume, the power of the heating system, the temperature difference, and the type of heater used. The energy required to raise the temperature of the pool is directly proportional to the amount of water in the pool and the temperature difference between the current pool water and the desired temperature.

The pool heating process requires energy input from a heater, which works by transferring heat to the pool water. The efficiency of the heater is a critical factor in determining how quickly the pool will reach the target temperature.

The calculation involves determining the total amount of heat needed to raise the water temperature, which is influenced by factors such as pool size, insulation, and external weather conditions.

Time, T in hours equals the product of the pool’s surface area, S_(ft2) in square feet, the temperature difference, T_(°F) in degrees Fahrenheit, and a constant factor (8.33), divided by the heating power, HP_(BTU/hr) of the system in BTUs per hour.

Time, T= S_(ft2) * 8.33 * T_(°F) / HP_(BTU/hr)

T= time in hours.

S_(ft2) = surface area in square feet, ft².

T_(°F) = temperature difference in degree Fahrenheit, °F.

HP_(BTU/hr) = heating powerin BTUs per hour, BTU/hr.

Pool Heat Time Calculation:

1.Calculate the time required to heat a pool with a surface area of 600 square feet, a temperature difference of 15°F, and a heater with a heating power of 50,000 BTUs per hour.

Given:S_(ft2) = 600ft², T_(°F) =15°F, HP_(BTU/hr) = 50000BTU/hr.

Time, T= S_(ft2) * 8.33 * T_(°F) / HP_(BTU/hr)

T= 600 * 8.33 * 15 / 50000

T= 74985 / 50000

T= 1.5hrs.

2.A pool with a surface area of 1000 square feet needs to be heated for2.08hrs. If the heater has a power of 80,000 BTUs per hour, calculate the temperature required to heat the pool.

Given:S_(ft2) = 1000ft², T= 2.08hrs, HP_(BTU/hr) = 80000BTU/hr.

Time, T= S_(ft2) * 8.33 * T_(°F) / HP_(BTU/hr)

T_(°F) = T* HP_(BTU/hr) / S_(ft2) * 8.33

T_(°F) = 2.08 * 80000 / 1000 * 8.33

T_(°F) = 20°F.
