How Long Does It Take To Heat A Pool With A Solar Cover. Solar covers will help a pool warm up faster in the spring and help maintain warmth in a pool a little longer in the fall but one misconception about them is that they will warm up a pool in the dead of winter, which simply is not the case. The rule of thumb for sizing is to use 50% of your pool surface area in solar panels.
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. Solar covers will help a pool warm up faster in the spring and help maintain warmth in a pool a little longer in the fall but one misconception about them is that they will warm up a pool in the dead of winter, which simply is not the case. An 18×40 = 720 sf, so you would want to have about 360 sf of solar panels.
Other than heating pools during the day, solar blankets also help the pool retain heat by protecting the water from cool night winds and air.
Solar pool covers are the ideal solution to. Determine the time required to increase water temperature by 1 degree f. During warmer weather with hours of consistent sunlight, solar panels can heat a pool to a comfortable temperature within a day or so. So now you know some factors that affect your swimming pool's or spa's required heating time.
