How Long Will It Take to Heat your Pool?

Want to know how long it will take to heat your pool in the winter season? Well, this is a question many people want to know, it is simple and complex as there are few variables to consider. The simple answer is to plug and play with this basic formula.

Gallons of water (GW) multiplied by the weight per gallon (8.33lbs) multiplied by the degrees desired divided by the BTU output you have purchased for your pool.

For example, a 15,000-gallon pool heated 20 degrees with a heater output of 3,36,000 BTUs would like the following:

15,000 x 8.33= 1,24,950 lbs of water

124950 x 20= 2,499,000 BTUs need to heat the water at 20 degree

2,499,000 ÷ 3, 66,000= 6.82 hours

The variables include factors like ambient air and water temperature, wind speed, hours of sun if it is direct or in the shade, surface area exposed to the elements and your resident area location. Needless to say, if you live at the north pole and it's zero degrees outside, the pool is 40 degree in the middle of winter and there is a 10 mile an hour wind it’s going to take a long time to heat your swimming pool than it would take in the middle of summer.

What would be the cost?

This is another frequently asked question. The constant in the equation in the therms per hour. There are 100,000 BTUs per hour for every one therm. Most gas companies in the USA use therms as a common measuring unit of gas used. So, a 4,00,000 BTU heater from the  best pool supply store Phoenix will use four therms per hour of operation. The equation would be the number of therms multiplied by the gas cost. If you gas costs you $1.20 per therm and we used heating time more than 6 hours we would get the following cost-

4 x 1.20= $4.80

$4.80 x 6.82hours= $32.73 would be your cost to heat the water initially
