The time it takes for a newly filled pool to warm up can vary depending on several factors, including air temperature, pool size, and the presence (or absence) of a pool heater. Without a heater, it might take several days for the temperature to become comfortable. Generally, with a pool heater, you can expect your pool to warm up by about 1°F to 2°F per hour. Therefore, heating a pool from 60°F to 80°F might take 10 to 20 hours.
