Yes: assuming you want your pool to be higher than 70 degrees. Trust me you do, the common temp for a pool is 82-84 degrees F.

weather and time my friend...weather and time.
I think it depends on weather the pool is heated. You want the pool to be a temperature that everyone can take. Also, outdoors will depend on the temp of your pool or any outdoor pool.
Well, it depends on the size of heat pump and the size of pool! However, a 30x12 ft, 2-3.5ft deep pool with an 18kw heater will take 4 to 5 days.
The purpose of a swimming pool heat pump is to rise the temperature of the water. The pool then can be used for swimming even on days when the weather is not perfect. The swimming pool season is extended.
you cover your pool to keep debris out and keep heat and chemicals in whether the weather is good or bad.
Your regular cover won't heat the pool, it will hold the heat, but it will not heat it up. You need a solar blanket if you are looking for something to warm your pool.
"Best" in cold weather climates would probably be an indoor pool. Most outdoor (either above-ground or in-ground) pools need to be completely drained (or always heated) during the Winter in cold weather climates, so that substantial ice does not freeze, expand, and crack open the side walls of the pool. You might also consider a darker pool surface since it will help keep the pool warmer by absorbing heat.
It takes 8.34 BTU to heat 1 gallon of water 1 degree F. Take 8.34 BTU times number of gallons to determine energy needed to raise pool 1 degree F. Then multiply by how many degrees you need to raise the temperate of the current pool temperature to the desired temperature. Example: 8.34 * 30,000 gal = 250,200 BTU need to raise temperature 1 degree F Next multiple by the number of degrees to warm, say the pool is 55 F. 80F - 55F = 25F. 250,200 BTU * 25 F = 6.255 million BTUs to heat the pool to 80 F. This does not take into account the loss of energy to the surroundings but gives you a starting point to determine the energy needed to heat a mass of water.
no you need a stronger heater specifically designed for a swimming pool
A solar cover can raise the temperature of a pool by around 5-10 degrees Fahrenheit, depending on factors like sunlight exposure, pool size, and ambient temperature. The cover helps trap heat in the water by preventing evaporation and heat loss.
To heat a 40,000-gallon pool by 30 degrees Fahrenheit, you'll need approximately 1,200 therms of gas. This estimation assumes that it takes about 1 therm to heat 1,000 gallons of water by 1 degree Fahrenheit. The efficiency of the heater can also affect the total gas consumption, but with a 400,000 BTU heater, it should achieve the desired temperature increase relatively efficiently.
