How long does it take pool water to warm up?

Do you know how long it takes pool water to warm up? You’ll need an appropriate method to heat your pool with the sun’s heat. 

To heat the water in your pool, you must have a pool that can absorb heat. A black water hose is all you need to create a stream in your yard. You’ll need to connect it to your water supply and leave it in direct sunshine. As soon as you turn on the faucet, you’ll notice that the water is nice and warm.

 You can still heat water-free despite the lengthy process. Also, keep in mind that the sun alone may not be enough to maintain your ideal temperature. 

Using a clear or blue solar cover will allow you to raise the temperature of your heater by a significant amount. Pool size, air temperature, and your desired temperature all affect the time it takes to heat a swimming pool with a heater or heat pump.

With a solar cover, you can keep your pool water warm all year round. A one-time investment is all that is required for this method to function.

Factors That Can Affect the Heating of Your Pool Water


When the sun is shining, a pool can heat up in 8 to 12 hours. Several variables can affect this procedure; therefore the numbers can be skewed.


The beginning water temperature of the pool has a significant impact on it. It will take less time for the sun’s pool to heat up if the water temperature is higher than typical. 

If, on the other hand, the water is cooler than typical (below 13 degrees Celsius), you may have to wait a bit longer to enjoy your pool bath.


In the absence of a heater, the sun is your best bet for warming up a pool on a cold day. An effective solar cover can help reduce evaporation and expedite treatment without using a heater.

The longer it takes to heat your pool, the bigger it is. To raise the temperature of your pool, you’ll need to eat more food. According to this idea, pools that can hold more water require a longer time to absorb the sun’s energy.

Air temperature

As long as the air temperature is above freezing, the sun’s rays will take a long time to warm water that is submerged. That’s why it’s important to consider the temperature difference between the air and water in your pool.

Heat loss

Different materials have different heat-absorption capabilities. Since heat loss is critical to this process, it should not be overlooked Temperature rises when solar panels absorb longer periods of light.

Sunlight angle

With sunlight, a 90-degree angle is optimal for heating a swimming pool. Your pool’s heating rate may decrease if you move it in the other direction from this one.

How much time does it take to heat pool water by the solar panel?

The advantage of this strategy is that you can enjoy the warm water for a longer time. The water temperature can be raised by 2.0-3.5 degrees Celsius in a single day by solar heating a 15-foot by the 30-foot inground pool with a storage capacity of 13000-15000 gallons. Make sure your pool is at the temperature you want by using a wireless thermometer.

How much time does it take to heat pool water with a pool heater?

For an inground pool with a capacity of 12000-15000 gallons, a heater or heat pump with a capacity of 8-12 hours should be sufficient.

How much time does it take to heat pool water with a pool heater?

It typically takes 7-10 hours to raise the pool’s temperature by 2-3 degrees Celsius.

Final Words: Practically speaking, solar-powered pool heating is a good idea. Sunlight can also help you minimize the amount of chlorine in your pool. However, the process may take up to 10 hours to heat it to its desired temperature. A solar panel heater or gas heater can be used in this situation.

They are more efficient and produce better results in a shorter period. With its pump and filter, a solar panel heater uses the sun’s heat to heat the pool water. 

Once installed, it provides free pool heating for the foreseeable future. Instead of using fuel to warm water, a gas-powered unit heats it. Solar panels are faster to install, but they need a significantly higher initial expenditure. If you’re searching for a low-maintenance investment, a solar panel heater can be a good option. 

With a gas heater, you can fast heat your pool water, but you’ll have to pay for the increased fuel expenditures. I hope after reading this content you don’t have any confusion about how long it takes pool water to warm up.
