No, practically speaking.
It is true that the action of the pump will generate some heat by friction - rather in the manner of Joule's classic experiment to determine this link - but what little is generated will be lost rapidly from the surface, especially in an outdoor pool.
[Joule set up paddles on a shaft in a barrel of water, rotated by a system of weights, cords and pulleys; and measured the temperature rise over many cycles of operation. By painstakingly repeating the test many, many times and endeavouring to account for frictional and direct thermal losses, he established the essential conversion of mechanical energy to heat. The unit of energy is the Joule, in his honour.]
Yes. We had a black/brown pepple tec installed over our stained concrete pool and it does make the water a little warmer. Not significantly but noticeble enough to enjoy a quick dip.
Absolutely. After replacing my white liner with a dark blue one I notice a difference of 5-10 degrees in the pool water depending on the amount of sun we are getting.
It is a unit that takes water and pushes it through the filter and returns the water back to the pool.
One of the best ways to prevent problems with your swimming pool is by running the pump and circulating the water. The best care for the pool varies depending on the type of pool you have but keeping proper water chemistry is important for any pool.
Well, large bodies of water take longer to heat or cool than land does, so a swimming pool will be a bit cooler... ... I think so....
it is an illusion. salt water pools have softer feeling water and may put you under the impression that it is warmer. however there is no difference between a salt water pool or a fresh water pool.
nothin to do with the colour ; it depends on the weather and also the chemicals mixed with it
Sure you can turn off the pool pump, the water won't be circulating anymore but since you are not using the pool it does not matter. Make sure the outside temperature is above freezing until winterizing because non moving water freezes earlier than moving water. Here is my blog on how I handle my pool: http: //live-efficient-green.blogspot.com/2009/07/pool-with-no-harmfull-chemicals.html
It gives the pool a different look than standard white. It can also be splotchy and mottled. It will not make the water warmer. This is purely and aesthetic choice. I particularly like the way 8 oz. of blue and 2 oz. of black gives the water a tropical look.
An empty pool of water is fine for several months, if it is made of concrete. Longer than that, and it could start to grow bacteria over time, especially in warmer conditions.
Yes you can add liquid chlorine to a pool even if it's not circulating
Pool filters keep the water circulating and algae out of pools. So, any size pool you pick that you want to remain bacteria free would need a filter. Usually a pool that is put up for long term use would need a filter.
