Typically, cop is measured by testing a heat pump pool heater with an outdoor temperature of 80 degrees.

How long does it take to heat a pool 10 degrees. 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. One of the easiest ways to reduce heat loss is by using a pool cover; 3/4 of the pool gets full sun for about 6 hours.

Heat loss is dependent on three main factors: But as pool owners we know how pricey it can be continuously heating a pool with a gas or electric heat pump, as well. Take 20% off of the btu rating of the heater.

5000 gallon pool with a 200,000 btu heater. 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. Overall, a heat pump usually requires between 24 and 72 hours to heat a swimming pool by 20f (11c) and between 45 and 60 minutes to heat a spa by 20f (11c).

Also note that, you may not get your desired temperature only with the sun. 166,800/125,000= 1.33 hrs to increase 1 degree. It is also very expensive to heat your pool when the ambient temperature is cool.

10 x 1.33= 13.34 hours of heating before the pool reaches 80 degrees f. For a typical size 400,000 btu pool heater, that's 4 therms per hour. 3,332,000 366,000 = 9.91 hours.

The rest will be significantly colder. 20,000 x 8.34= 166,800 lbs. The solar heaters get about 4 hours of some sun on a good day.

* ambient temperature * angle of the suns rays to the pool surface * how much water is uncirculated in the filtering system (to a small degree only!) However, to attain this measure, you need to cover up the pool as much as possible and also the pool needs to get at least 6 hours of sunlight every day. Of course, its also vital to remember the importance of maintaining your pool heat pump.

If you are looking to heat your pool close to 90 degrees, you will only be able to do that about 320 days of the year. This is assuming your heater is working well and its a fairly sunny day. Natural gas heaters (also known as ng heaters) use about 1 therm per hour per 100,000 btu's.

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). Cops usually range from 3.0 to 7.0, which converts to an efficiency of around 500%. Depending on the depth of your pool, using only the sun to heat your pool seems ridiculous;

You will have to calculate your heat loss too. Heat pumps become ineffective when the ambient temperatures are very low. However, there are some things you can do to speed up the process.

How long does it take for a pool to heat up by the sun? The warmer it is outside, the less time it will take to heat. Always oversize when purchasing a pool heater.

Within these cold temperatures you will find defrosting which is a process to protect the heater from freezing over in very low temperatures. The temperature difference between the air and surface water of the pool, the total surface area of the pool, and the heat loss factor due to wind velocity. 5000*8.3 = 41,500 lbs of water.

Overall, a heat pump usually requires between 24 and 72 hours to heat a swimming pool by 20f (11c) and between 45 and 60 minutes to heat a spa by 20f (11c). The time it takes to warm an unheated outdoor swimming pool depends upon three factors: Generally, it takes the cover 12 hours to heat pool water by 5 degrees.

So now you know some factors that affect your swimming pool s or spa s required heating time. How long will it take before the pool water reaches 80 degrees f? One thing no one has mentioned is that the solar cover will heat the first few inches of water.

You can increase its heating rate and more temperature by using a solar cover. A solar cover traps the heat and keeps the pool water warm. So, if you want to raise the water temperature by ten degrees, then you would need 1,660,000 btu's of heat energy.

On average, most hot tub owners say 4 hours is pretty common. How fast does a gas heater heat a pool? Now given it would take five days to heat the pool in perfect conditions, once we factor in actual heat loss the 110v becomes pretty infeasible.

They are not powerful enough to heat a whole pool, and are wildly inefficient. I do not believe you will get 10 degrees with only a solar cover. As an aside, i always used about a 250,000 btu heater on everything,.

Who knows how long that could take. On average, time to take for a pool to heat up by the sun is 8 to 12 hours. Your water is currently 70 degrees f but you would like it to be a minimum of 80 degrees f.

This holds true for all major brands of pool heat pumps, including raypak, hayward and pentair heat pumps.
