How Long Does It Take To Heat A Pool 20 Degrees

July 19, 2021

For heat pumps, the efficiency varies depending on the air temperature and therefore the calculations cannot account for cooler temperatures. So if you have a 400,000 btu heater that is 84% efficient and you need to heat up 1200 gallons of water 20 degrees, you can figure it out this way:

So now you know some factors that affect your swimming pool's or spa's required heating time.

How long does it take to heat a pool 20 degrees. How fast solar covers heat a pool: Overall, a heat pump usually requires between 24 and 72 hours to heat a swimming pool by 20°f (11°c) and between 45 and 60 minutes to heat a spa by 20°f (11°c). The rate at which water is heat depends significantly on the intensity of the sun and the period the water receives direct sunlight at large.

The british thermal units (btu) per hour is used to size the heat pumps and heaters. 1,200 gals x 8.33 x 20 = 199,920 btus are required to heat up the water. So now you know some factors that affect your swimming pool's or spa's required heating time.

So now you know some factors that affect your swimming pool's or spa's required heating time. On average, most hot tubs will take about 4 hours to reach 100 degrees. This holds true for all major brands of pool heat pumps, including raypak, hayward and pentair heat pumps.

Electric pool heaters just remember that external weather conditions can affect the heating capacity of an electric pool heater but don’t have to rely on sunlight, as solar heaters do, to heat your pool. If the water temperature is 10 degrees fahrenheit, for example, it can take longer than if it is 20 degrees fahrenheit. Generally, it takes the cover 12 hours to heat pool water by 5 degrees.

Always oversize when purchasing a pool heater. Overall, a heat pump usually requires between 24 and 72 hours to heat a swimming pool by 20°f (11°c) and between 45 and 60 minutes to heat a spa by 20°f (11°c). As a result, if the water temperature in your pool is lower, you'll need more solar light time to heat it.

Factors include the capacity of the tub, ambient air temperature, and the temperature of the water from the hose. One btu raises one pound of water by 1 degree f. Our heater manufacturer (raypak) has always told us, if the heater is sized for the pool properly, (whole other topic) the heater should be able to heat the pool one to two degrees per hour, not counting heat loss.

Here’s what i’ve found in owning 4 of them: On average, time to take for a pool to heat up by the sun is 8 to 12 hours. For smaller pools like a spa pool, the heat pump can heat a pool between 45 and 60 minutes.

Overall, a heat pump usually requires between 24 and 72 hours to heat a swimming pool by 20°f (11°c) and between 45 and 60 minutes to heat a spa by 20°f (11°c). Therefore, you will need 8.34 btu to heat a gallon of water by 1 degree f. Pool heater time to heat and cost to heat calculations > the formula is pretty simple.

Also, for your notes jamie, this same configuration should heat the spa 1 to 2 degrees per min. It depends on a few things to determine how long it takes a heat pump to heat a pool. 3,332,000 ÷ 366,000 = 9.91 hours.

Also question is, how long does it take to heat a pool with a heat pump? Y ou can increase its heating rate and more temperature by using a solar cover. So now you know some factors that affect your swimming pool's or spa's required heating time.

Take the gallons of the pool and multiply by 8.3. In most cases, calculations for a heat pump and heater are optimistic. The exact time needed to change the pool temperature will vary based on evaporation rate, convection losses, thermal radiation losses and conduction losses (explained more below).

10 x 1.33= 13.34 hours of heating before the pool reaches 80 degrees f. Which means it will only heat every twelve hours for two hours, or as long as it takes to get up to temp and then the heater will turn off. Overall, a heat pump usually requires between 24 and 72 hours to heat a swimming pool by 20°f (11°c) and between 45 and 60 minutes to heat a spa by 20°f (11°c).

That gives you the weight of the water. One of the easiest ways to reduce heat loss is by using a pool cover; The precise heating rate depends on the size of the pool, outdoor temperature, and whether or not a solar cover is used.

It can take anywhere from 3 to 8 hours for hot tubs to reach the desired temperature. That a cover helps control this heat loss. A solar cover traps the heat and keeps the pool water warm.

(one gallon of water weighs 8.33 pounds) the heater will deliver 400,000 x.84 = 336,000 btus to the water in one hour. 8.34 pounds of water, makeup one gallon. If that's the case, you may want to change the setting and have it always stay at a set temp.

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 where you are located. Also, note that you may not get your desired temperature only with the sun. Besides this, the size of your pool and the weather condition of the area you live in other dependable factors.

Of course, it’s also vital to remember the importance of maintaining your pool heat pump. Take 20% off of the btu rating of the heater. 166,600 x 20 = 3,332,000 btus needed to heat the water 20 degrees.
