diy solar pool heater

Last year, my wife and I bought a pool on the ground for sports and entertainment.
We found that my home was shrouded in the pool in the afternoon, which made the water temperature drop several degrees in spring and autumn.
Since we usually do not enter the pool until after work on weekdays, this is a good option for some very cold swimming, even if the temperature is 80 degrees.
I decided that the solar heaters I could install outside the shadow of the house were just things that raised the water temperature to a more affordable level.
I took a piece of 4x4 plywood and painted it black.
Then I took the 1/2 vinyl irrigation hose with UV-resistant zip-
Fix the hose per foot or so by drilling and looping the zipper
Tie the hose and plywood together.
As you can see, the plywood is not completely covered, however, since I did not use the round coil but followed the square edge, I had a problem with the hose starting to twist in the corner.
If you look at this picture carefully, you will find that I still have some problems to solve.
Everything was done and in the sun I made a temperature reading on the surface of the board around 3: 00 pm.
The surface reading is about 134 degrees Fahrenheit.
Now we have to put that lovely heat in the pool.
I used the natural flow and pressure of the existing pool filter pump, assembled a series of valves and \"Y\" adapters, took the waterway from to the heater and then returned to the pool instead of a separate pump.
1/2 \"The ball valve allows me to turn off the water that goes in and out of the solar heater and remove it once the afternoon temperature makes it unnecessary.
The top is a smooth 1 1/2 \"Y\" adapter with a thread adapter of 1 1/2 to 1/2 on one side, there is a 1/2 \"male to male\" threaded nipple and a 1/2 threaded to rib adapter for sliding of a 1/2 ball valve vinyl hose.
To avoid leakage, I used two hose clamps on each hose fitting.
Polish all smooth surfaces before gluing to ensure good sealing.
Important: Do not glue any threaded parts.
The glue will solidify for a long time before you tighten the line.
Seal threads using plumber grease or pipe paint.
Even Teflon tape may leak due to high pressure.
The intermediate valve is a smooth 1 1/2 \"ball valve that is glued to a short part of the 1 1/2\" PVC on both sides.
By partially closing the valve, the pressure will transfer some water from the top \"Y\" adapter to the solar heater panel.
The bottom of the component is almost a mirror image of the top.
Rib to 1/2 Threaded Adapter for 1/2 threaded ball valve, 1/2 to 1/2 threaded joint, 1 to 1/2 smooth adapter, smooth 1 1/2 \"Y \".
The water flows down from the 1 1/2 \"PVC pipe through the 1 1/2\" ball valve, sucking the water from the solar heater into the water flowing into the pool.
If the water is allowed to flow continuously through the solar heater, hundreds of gallons of cold water in the pool can drown out about 10 gallons of water in the solar heater.
It didn\'t have enough time to heat up at all until it was delivered to the pool.
To fix this, I installed an outdoor timer on my pool pump.
The pump still runs several hours a day to filter the pool, but from noon to around 6: 00 pm the timer turns on and off the pump every 1/2 hours.
This allows the water in the solar water heater to have time to heat before entering the pool.
As you can see, the water flowing into the pool is about 99 degrees Fahrenheit when the heater is running.
The entire pool is kept at 84-
86 degrees in the shade.
Everything was purchased at Home Depot for about $50.
Now my wife and I can enter the pool with \"ahhhh\" instead of \"Oooooooooo.

Shaken, Stirred and Elementary: ‘Sherlock Holmes’ and ‘Thunderball’

Image
Created by Arthur Conan Doyle, the detective Sherlock Holmes belongs to us all. As noted by the historian Michael Saler in "As If," his account of literary imaginary worlds, the great detective was modern fiction's "first virtual reality character" — given that part of his readership chose to believe that he was an actual person. The 1916 movie "Sherlock Holmes" (newly restored and released by Flicker Alley in a dual Blu-ray/DVD edition) grounds that character's virtual reality in a corporeal presence, namely that of the tall, craggy American actor William Gillette (1853-1937). Mr. Gillette, the son of a United States senator from Connecticut, was Holmes's contemporary. It was during the hiatus between the fictional character's apparent demise in a struggle with Professor Moriarty and his return to life by popular demand that Mr. Gillette got the opportunity to take the title role in a revision of Conan Doyle's unproduced Holmes play. ...

Since its activation on one of the belts in the world is earthquake-resistant structures and thus create safety is the priority. The need to evaluate residential units indicates that the young tissue workforce each year about 600,000 new housing units are needed to cover a limited part of the traditional methods of construction. In addition to the new requirements, poor quality of room construction caused by the depreciation of existing buildings, which will increase the need for new construction, retrofit of existing structures as well as the issue of the necessary attention, should be given. Due to the broad needs of listed buildings and the need to improve production quality, as are common in most large countries should seriously consider building manufacturing method...
