As i live in a region that snows in the winter does it make sense to have a solar heater.
How long does it take to heat a pool without a 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). This is why most pool owners are advised to use solar covers, especially during the wintertime and at night. You poke a couple of holes into this object and place it.

9kw will heat a pool up to 18ft round. Although not the most effective, solar pills are a very economical way to heat up your pool. They typically need to run for 4 to 6 hours per day to maintain the temperature.
Even if you could do this, the spa heater will probably be too small to add any substantial heat to the pool and cost too much to use (electric heat). On average, time to take for a pool to heat up by the sun is 8 to 12 hours. Y ou can increase its heating rate and more temperature by using a solar cover.
As an aside, i always used about a 250,000 btu heater on everything,. In a 150 day season your lecky bill. 20,000 x 8.33 = 166,600 lbs of water.
In most cases, calculations for a heat pump and heater are optimistic. A product life of 10 to 12 years is not uncommon. How long does it take to heat a pool?
3,332,000 ÷ 366,000 = 9.91 hours. Furthermore, how long does it take to heat a pool without a heater? Using this method, you are supplied with a solar pill, which is basically a ball filled with liquid solar.
So then what happens when it’s really cold outside and there’s no heat to take? That’s why there are other methods that you can choose from. Hi i have an indoor pool that is approximately 20k gallons circa 1985.

* ambient temperature * angle of the sun’s rays to the pool surface * how much water is uncirculated in the filtering system (to a small degree only!) the high. A 400mj/hr gas heater will heat the spa water in approximately 40 minutes which seems about as long as most customers want to wait around to heat their spa water. Could we add a heater later, after our pool is built?
Generally, it takes 1 btu to create up heat of1degree in a pool. A solar pool cover serves all these purposes with a few added benefits. There’s no heat to take.

It is currently heated to 84 degrees with a large propane pool heater. Will freezing winter weather actually rob the pool of heat when circulating the water through the solar panels? 5000 gallon pool with a 200,000 btu heater.
If you’re hoping to take advantage of your pool heater before cooler temperatures start to kick in, call air on. For heat pumps, the efficiency varies depending on the air temperature and therefore the calculations cannot account for cooler temperatures. Although this process is slow, you can still heat water for free.
We also offer an even more affordable way to heat your pool which also retains chemicals inside the pool. The precise heating rate depends on the size of the pool, outdoor temperature, and whether or not a solar cover is used. 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.
10 x 1.33= 13.34 hours of heating before the pool reaches 80 degrees f. You will have to calculate your heat loss too. But unless there is some sun in your area even during cold weather, this method may not work that well.
