How Long Does It Take To Heat A Pool 10 Degrees. Natural gas heaters (also known as ng heaters) use about 1 therm per hour per 100,000 btu's. Your water is currently 70 degrees f but you would like it to be a minimum of 80 degrees f.
The time it takes to warm an unheated outdoor swimming pool depends upon three factors: One thing no one has mentioned is that the solar cover will heat the first few inches of water. Within these cold temperatures you will find “defrosting” which is a process to protect the heater from freezing over in very low temperatures.
Your water is currently 70 degrees f but you would like it to be a minimum of 80 degrees f.
10 x 1.33= 13.34 hours of heating before the pool reaches 80 degrees f. For example, if it is 76 degrees outside and you want your hot tub to be 100 degrees, it will take your hot tub approximately 4 hours to reach its temperature. The warmer it is outside, the less time it will take to heat. Depending on the depth of your pool, using only the sun to heat your pool seems ridiculous;
