I would definitely not classify it as "very loud" but rather "very quiet". I'd say try something for fountains, as they tend to be artistic pieces which need to be quiet anyway.Holdenhttps://www.blogger.com/profile/01164992563260946309noreply@blogger.comtag:blogger.com,1999:blog-1120086448884995573.post-7298760537799553482013-06-16T20:25:18.835-07:002013-06-16T20:25:18.835-07:00Thanks for this write up on your system!

I put together a similar but on MUCH less grand scale last year and in principle it worked very well. But I used a cast iron transfer pump and while it moved water just fine it also moved a lot of rust with it. It was also very loud. I'm definitely looking for a SS pump for this season and would love to hear about the one you've selected as far as noise. Is it loud? Have you done anything with placement to deal with noise if it was an issue?

Of course, your materials may be different. For the simplest approach I would think it would suffice to do as I have, and after one season, simply inspect. If you have to put something under at that point, it is possible to drain and re-fill the tubes.Holdenhttps://www.blogger.com/profile/01164992563260946309noreply@blogger.comtag:blogger.com,1999:blog-1120086448884995573.post-8312281658340212982013-03-12T06:19:08.772-07:002013-03-12T06:19:08.772-07:00Thanks Holden, that's helpful. With regard to ...Thanks Holden, that's helpful. With regard to the expansion/contraction, do you have any concerns regarding the system wearing holes in the shingles over time? I've seen that mentioned with regard to some improperly installed professional systems, and wondered if it would be an issue with yours. The solution they recommended was to attach a sheet of tin under the potential wear spots.

There's no hard fastener. Being that the coils are so dense / heavy and that they are not a large wind catcher due to being low profile, there's nothing except gravity holding them in place. It hasn't been a problem, even when they were empty coils (no water), there was enough weight in windy conditions. What I did have a challenge with was slow creep, down the low incline of the roof, and so I just tied the coil frames to each other, across the apex of the roof (pulling against each other). This slow creep happened over weeks/months, and I think mostly due to the heat cycling which caused some cyclic expansion / contraction. (Movement was measured in inches over months.)Holdenhttps://www.blogger.com/profile/01164992563260946309noreply@blogger.comtag:blogger.com,1999:blog-1120086448884995573.post-11277506720317070722013-03-06T09:15:15.800-08:002013-03-06T09:15:15.800-08:00I'm very interested in doing this type of thin...I'm very interested in doing this type of thing myself, and your version looks very easy and affordable.

With PV panels you'll probably want an inverter and grid-hookup & metering, and then a lossy electric pool heater on top of all of that.<br /><br />With the setup above it's a self contained unit, no electrical work, and it's even quasi-uninstallable, if need be. :)Holdenhttps://www.blogger.com/profile/01164992563260946309noreply@blogger.comtag:blogger.com,1999:blog-1120086448884995573.post-56206330079702911842012-11-12T01:01:38.296-08:002012-11-12T01:01:38.296-08:00I see,this seems a legit looking job for home sola...I see,this seems a legit looking job for <a href="http://americansolardirect.com/Benefits-of-Solar/Overview.aspx/" rel="nofollow">home solar</a>,thou,I think it will really get complicated.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1120086448884995573.post-10903624925127347712012-06-13T12:12:10.536-07:002012-06-13T12:12:10.536-07:00@Anyonymous - thanks for the input.

The pump we have is quite over sized and really passes water quickly, and so we felt like a bit more 'dwell time' might help heat transfer. I think you're right, on hot days, we'd want to go back to a series setup, as it comes out quite hot.<br /><br />-HBHoldenhttps://www.blogger.com/profile/01164992563260946309noreply@blogger.comtag:blogger.com,1999:blog-1120086448884995573.post-87164763321071458462012-06-12T12:04:55.969-07:002012-06-12T12:04:55.969-07:00The idea of "slowing down the flow" to r...The idea of "slowing down the flow" to raise the outlet temperature is actually the oposite of what you want to do to maximize the energy transfered to the pool. Heat transfer is a function of the temperature difference. Therefore the higher flow rate and subsequent lower average temperature profile through the exchanger will result in higher energy transfer, not lower. Although it will be cooler to the touch coming out, it will lead to faster temperture gains in the long run.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1120086448884995573.post-68237543059198163942012-05-28T12:53:40.442-07:002012-05-28T12:53:40.442-07:00The gas market collapsed the past two years, so it...The gas market collapsed the past two years, so it's a good time to have gas.<br /><br />Then again, I'm fairly sure the cost of sunshine is going to be stable for the next few millenia.<br /><br />-HBHoldenhttps://www.blogger.com/profile/01164992563260946309noreply@blogger.comtag:blogger.com,1999:blog-1120086448884995573.post-90339601970817310962012-05-28T10:57:36.756-07:002012-05-28T10:57:36.756-07:00I tried to get my neighbor interested in this idea...I tried to get my neighbor interested in this idea, but in the end he went for the gas heater. ugh.Matt Quinnhttps://www.blogger.com/profile/09693750032188942876noreply@blogger.com
