Pool Heating

No, not significantly. The fact that you use a solar cover at all is much more significant then what color it is. For all of the physicists out there, there ARE differences between the colors, but there are other factors like air temperature, ground temperature, and amount of sun that your pool receives, that will have a much greater effect on the water temperature than the color of the solar blanket. Thus, many people make their color choice based on other factors: - appearance (some people don't like the look of a black pool cover) - cost (some retailers charge different prices) - availability (some retailers only stock certain colors). Overall, I would say that Blue is probably the most common. Hope this helps ... Thanks for the input Tom. I purchased a 12 mil Blue/Silver solar blanket about a month ago. I agree, color doesn't make a great big difference and I like the appearance of the Blue. So far I see a pretty significant retention in heat and I also use quite a bit less liquid chlorine when the cover is in use.

For Los Angeles I take the low temp for the night plus the high temp for the day add them then and divide by 2. For the summer I add 3 degrees and for the winter I subtract 3. That usually pegs it pretty close. Also for a dark bottom pool I add an additional 3 degrees during summer. Not scientific but it generally gets it pretty close. For instance today it was 83 during the day and 64 last night so 83+64/2=73.5 + 3=76.5 and 79.5 for darker bottom pools. Depth, color, and amount of sun that hits the pool all change things. Oh this is for inground pools.

Most likely one or two of the burner orifices near the pilot light are clogged making the gas travel a distance before lighting. Pull the burner tray and clean it completely. And check for spider webs and other debris in the burners. Check for other gas leaks, and don't use flex lines, flanges, valves, or other fittings inside the heater. On the Series One, check the sidewalls to make sure they are intact.

I cannot find a current listing for Teledyne Laars. As far as I can tell, Teledyne and Laars separated, Laars joined up with Waterpik and then got reorganized under Jandy. www.jandy.com now has the Laars Lite2 line of pool heaters with the LG model almost identical to the Teledyne Laars LLG. You can access the manual at http://www.jandy.com/pdfs/H02359-.pdf . Jandy also has a parts list for older discontinued models.

Stainless Steel Heat Exchangers are produced and distributed by Triangle Tube Products . Although stainless steel is highly resistant to corrosion, it is also more expensive and has a lower coefficient of heat (transfers less heat) than other metals. So, like most things in life, it's a trade-off between co$t, performance, and longevity. Hope this helps ... If resistence to corrosion is the main priority, Titanium is used.

A pool painted in a dark color will ABSORB more heat than a pool with a light colored paint. Thus, the water temperature will be slightly higher. However, the paint color is a secondary factor in determining the ultimate water temperature. Factors such as air temperature, ground temperature, and solar intensity will affect the water temperature more than the paint color. Other secondary factors include wind speed and humidity (which affects the evaporation rate). Thus, it is very difficult to predict how much higher the water temperature would be for a dark colored pool as compared to a light colored pool due to the many variables involved. If I had to guess, I would say that you might get an average boost of something like 1-3 deg F with a dark painted pool - possibly a little more than that in the middle of the summer. In regards to RETAINING the heat that was absorbed, the color of the pool is nearly irrelevant. The most important factor in this case is the difference between the air and water temperatures - the greater the difference, the more heat will dissipate into the air. The best way to RETAIN heat in your pool is to use a solar blanket to keep the heat that is already there from transferring (radiating) into the air. Especially at night when the air/water temperature difference is greatest. Hope this helps ...

According to Wiki s.com to convert horsepower to kilowatts you multiple the horsepower by a factor of 0.746.

How do you convert horsepower to kilowatts

However, you are saying that your 1 HP motor uses 1.84KW instead of 0.746KW which doesn't make sense to me.

You will be shocked by how much your electric bill will rise by the use of the pool pump. To figure out how much, find out the Kilowatt (KW) rating of your main pool pump and your pool sweep pump and multiply this by the number of hours each runs. Then multiply this by your electric bill Kilowatt-hour (KWh) rate.

For my 16,000 gallon pool which uses a 1 HP motor at 1.84 KW running 8-10 hours per day plus a 0.75 HP motor at 1.495 KW running 3 hours per day for the pool sweep, the cost is $75-$90 per month (at 13 cents per KWh).

I have a 15000 gallon pool with a 1 HP motor running 10-12 hours per day. The electric bill is $100-120 per month.

I have found the most effective way to get rid of the water sitting on top of a pool liner, is to purchase a submersible pump at your local hardware store, with enough hose to extend from the pump to where you want the water to drain (yard). AND ensure you have a top quality extension cord so you don't electrocute yourself or others if the connection goes under water. Just push the submersible pump to the deepest part of the water on top of the cover, plug it in, and it will drain a large part of it away before you even start removing the cover for the summer. Or you could filter the water after treating it with chemicals and pump it under the cover so you don't have to wait for rain or buy water to top off the pool. It does't have to be perfectly clear because you will treat all the water when you take the cover off.

Low pH causes more damage than chlorine on copper plumbing.

Nonetheless, high chlorine levels, sulfur compounds, metal scavengers and the high salt levels from the spent chemicals are all erosive to copper piping. Flow velocity is also a key factor in determining the rate of erosion. At 7gpm expect no more than 10 years life for 1" type K (very heavy) copper, 5 years or less for type M (typical low budget) copper. Copper pipe is not recommended for pool plumbing. Cupronickel alloys that do not contan zinc or tin are corrosion resistant in pool water, as are 300 and 400 series stainless steels, some more so than others.

Absolutely Not!

I am in phoenix arizona. I have a 12-14,000 gallon in ground pebble tech pool and a 400,000 btu natural gas heater. Would like to know costs to heat pool of in phoenix, with a natural gas heater. Please state approximate pool size, in gallons and if you heat your pool a few times a month or all month long. Obviously winter would cost more than summer.

Here are the possible problems. 1. Is the backup valve stuck in backup? 2. Is the pressure correct? Wheels turn 28-32 RPM. 3. Is there air in the filtration system? 4. Are the hose floats in the proper placement?

OR

Air entrapment within the housing. Tilt the unit back and forth while holding it under water - - - watch for air bubbles then let it go.

Sunny days provide the most solar heat to warm the water. So, no, do not remove the solar cover unless you're going to use the pool. And then put it back on when you're done swimming to help keep the heat that was absorbed during the day from being transferred into the cool air during the night. Hope this helps ... On a sunny calm (not windy) and warm day, you will gain more heat with the solar blanket off than on (since the blanket actually blocks some of the sun). On a windy, cloudy, or cold day, evaporation cooling may be greater than the sun warming effect so leaving the blanket on makes sense. Leaving it on day or night also makes sense if conserving water or chemicals is your main goal (reduced evaporation). Leaving it on at night or when the temperature of the water exceeds that of the air by some amount also makes sense. Leaving it off day and night early in the season when the water is colder than the air also makes sense (it will hold the cold in). Leaving it on too long (day or night) makes your pool green.

If you want to heat your pool you first have to turn on the pump because nothing works without the pump running.

You will not get filtration, circulation or heat.

Turn on the pump set the thermostat to desired temp range. If you are starting with a water temp of about 55 degrees more or less, you will want to run the pump non stop until you achieve a temp near your desired goal. -- Quicker recovery time with this method is achieved rather than running the pump a few hours then shutting it down until the next day etc.

You do not have to turn the heater on until you are ready to heat the water, some installers put a tee or bypass before the heater so the water does not go thru the heater many do not since the heater is on the clean side of the filter, some people just want a bypass valve their in case the heater fails they can keep the water flowing around the heater, Take the cover off, start the filter up, start vacuumimg, when ready add your chemicals. continue running the filter get your water tested, when you feel you are about ready too swim turn the heater on too warm the water if you desire to.

Put a 1 1/2 PVC pipe down the middle of the cover . Attach it to the cover with stainless bolts ,nuts, washers. Put an elbow on one end so you turn the pipe. The cover will roll up quickly in the water . I would recommend a thin cover to make it easier to roll

Yes without a doubt they work, but depending on your situation. First let me explain how solar blankets work. The blanket is tinted blue and has air pockets it looks like the bubble packing material that everyone loves to pop, but you cannot pop this material because it is between 8-12 mils thick. The blanket is designed to do 2 things, first is heat the pool water by absorbing sunlight that heats the blanket. The water in turn cools the blanket. As this occurs the heat of the blanket is exchanged with the pool water. The more sunlight the pool gets the faster the pool will heat. On average with full sun you can expect a degree a day so in about 7-10 days you will have about a 10-degree increase. The other thing a solar blanket does is trap heat in the pool water. At night when it gets cool the pool water will begin to condense out of the pool that is the fog you see rising from the pool, this draws the heat out of the water. The solar blanket bocks this from happening so all that heat you built up will stay in the pool. So you get the heating during the day (the solar part of the equation) and you get the thermal protection at night (the blanket part of the equation). If you don't get much sun on the pool the blanket will not heat the pool. So the bottom line is no sun on the pool no heating effect from the blanket. Sun on the pool for at least 5+ hours you will get heat! If you have a heater on the pool, regardless of they type of heater, you will want a solar blanket to trap the heat in the pool. If you are using gas or electric heat the blanket should cut your heating cost in half. If you are using a solar panel you will need it to trap the heat in other wise you may not be able to maintain the temperature when it gets real cold. == Solar Cover Yes not only do they keep heat in your water they keep chemicals in also. During hot days they do heat the water. HOWEVER, in my opinion depending on how large your pool is you may find that dealing with this giant piece of bubble wrap is just too much work. The pool is supposed to be fun and I must say rolling it out, rolling it back up took so much work for me it just wasn't worth it.

so that the room get's conversation from the warmth given in changing rooms.

The most economical way to heat an inground pool is to use a solar pool heater. Solar heaters provide a cheap efficient and eco-friendly way to warm up your pool. Here are some of the benefits of using a solar pool heater:

• Inexpensive to install and maintain
• No need to run electricity
• Heat pumps can be used to supplement the solar heater
• No emissions

A solar pool heater typically consists of a series of tubes or panels that are installed on the roof or ground depending on the design. Water is pumped through the tubes which are heated by the suns rays. The heated water is then returned to the pool thus raising the temperature of the water. In addition to using a solar pool heater you can also consider using a pool cover to keep the heat in and reduce evaporation.

Down, if you hope to heat your pool with it the bubbles (in theory) will heat up from the flat side. As there is more surface area from the bubbled side more heat (energy) will transfer to the water. I've never read any studies myself but I've read differing opinions from people in other posts. Some state the the solar cover actually blocks the sun and less heat is transfered on sunny days and that it is more beneficial to use take the cover off. Personally I find that if you leave the cover on when not using the pool, except when it's raining, the temperature stays the highest. Ensuring the cover is clean and there is no standing water on top of the cover really helps.

You should call the manufacturer. Pentair is 800-831-7133 and Hayward is 866-429-7665. Jandy, Zodiac, is 800-822-7933. There are typical sizes i could give you, but it's gonna be very upsetting if you need to rerun piping because of low pressure.
