New solar system ( professional ) - I'm impressed.

New pool Heater

Hi all,

Well, I took the plunge last week and bought a single solar panel from a company to see what the difference was between my nice homemade system and a professional one.  Well, I'm impressed, and depressed.  I guess I am glad I'm impressed because the professional solar panel was expensive.  Anyway the thing puts out tons of water, and from what i have read, it's not just heat you need it's heat AND flow.  You can burn your finger with a match, but you can't heat a pool - meaning my little 1/2" tube homemade solar system is nice, but it's not going to do a great deal to heat an 18 foot above ground pool which is 5 feet high, - that's a LOT of water in there.

Once I got the professional system running today with the very large 1-1/2" tube, I quickly realized my that my system although cute was not anywhere near as strong as this one panel.

In any event, I am glad i tried using black hosing to heat my pool, and indeed it DOES work, no matter what any salesman will tell you, - you just need enough flow to get a pool warm.

I now want to buy another 4 panels from this company, - each kit or "panel" is 40 sq.feet, and with 5 panels, that makes 200 sq. feet, which should be enough to do my pool... - most places suggest 60% of your total area of pool.

In my case the pool is an 18foot, round above ground pool, so that's 256 sq. feet approx, so I'm well over the 60% needed to heat that pool quickly.

Anyway here are some images to check out.

Mark.

Does this mean my HOMEMADE solar system failed ? - by all means NO... and that's a very positive NO !, if I had the room - say I was living out in the country or had a lot of propery, I could use more black hosing and would have very good sucess with my homemade system.

What you see in the images is ONE panel - eventhough you see 4 pieces, it is actually only one panel or "kit" ... which equals 40sq feet.

Install was easy, and I'm more than impressed.  Now to find somebody who doesn't scare easily and install this and other panels on my roof.... I have a 2 story house, and it's just impossible for me to even put my life on the line to put a solar panel system on the roof.

How I envy people who have a single story house .... they have it so easy :-)

Mark.






Editors Note: I fixed it so those huge photos show on a reasonable screen width. Hopefully DanF can get that fixed soon.

Hey I'm impressed you can buy solar heating from a box. Can you tell me the name of the company makes/distributes/sells it?

Thanks - happy swimming

I have a small question.

Would't you get hot(ter) water if you "recycled" it? Simply have a small output flow, and simply run the water in the system a bunch of times, while just a little bit gets out. Then the water inputted would be warmed quicker by the already hot water.

Hi Andrew,

The professional panels are very effecient, that there's no need to recycle the water again into them, - they put out pretty hot water the first time, and the more panels the hotter the water.

I got an email from my brother this morning saying he was talking to his friend this weekend and the guy was saying that the 4 panels he has hooked up on his roof ( they are professional ones ) as you see in my images, - anyway the water is so hot that he can make coffee with it.  That's pretty darn good.

My brother also knows the guy "aint" fibbing, as he was in the guy's pool a few weeks ago and it was 94 degrees ! - his wife had forgotten to turn the darn solar system off !

I wish I had that kind of problem.  Anyway I've just ordered another 2 panels this morning, and will hopefully get them this Thurday, and that will make a total of 3 for me.

I also found out that solar panels on a roof can cause major damage to your shingles, - because of shifting due to the constant movement of water in the panels and tubes.  I have therefore decided to build a structure on my lawn for my solar panels.  My home is only 4 years old, and the roof is under warranty for 15 years, -if I place the solar system on the roof, and in 5 years the shingles are worn through the company that did the job will NOT honor the warranty.  - Too much of a risk for me, so I'm keeping them on the ground.

I'll build a "deck" of sorts made out of pressure treated lumber, cover it with shingles, and then attached the solar panels on there.  Much cheaper than replacing a roof at $5,000.

anyway that's it for now.

Mark.

Here are some new pics I took of the solar panel.

Pump? (none / 0) (#3)

Does the professional heater have it's own pump?

Uncommon sense required.

Hi Demetri,

Nope, none needed, it just uses your existing pool pump, which is strong enough to power it.  3/4 to 1hp is what they ask for.  I have a 1.5 hp, so I have the valve that goes to the panel closed down about 80%, and still I am getting a big water flow.

I just also ordered 3 more of these panels today, so they should be here by Thursday, and by Friday I'll have 'em hooked up, so I'll post a few more pix of
the 4 panels hooked together.
