Hello
I just joined the forum and am anxious to learn and contribute.  But there is an issue with the forum.  Instead of the comments being on the screen in the text area, they are all to the right in a narrow column.  Is this the normal view or is there a setting I have missed?

Using a tablet?

The posting looks correct on my side. Another new member complained of the same thing.

This was tablet issue I think with certain browsers.  This recently came up, not sure where it was posted but some browsers did not like the forum.  They used a different browser to fix but I do not remember if Chrome was the cure or the disease.

Hi Scott, thanks for all that you do.

Quick question about your solar thermal tank.

How does the water get pumped to the tank from the solar collectors?

Thanks,
Steve

Welcome Steppen,

I'm sure Scott will respond, but mostly there are two type of hot water systems, open & closed. I have an open system, where the hot water returns to a small tank & the pump starts the process of circulation.

I believe Scotts system is a closed system. He also had to insulated the pipes very well since it's some distance between the panel an home.

Welcome again

Thanks Jeff, I know a guy who has about 20 4by8 used panels made from copper.  The casing are in fairly good shape, but the glazing or plastic is pretty opague (yellow) so I will have to replace it.  These panels have very thin channels, maybe 30 channels (1/2" wide, 8' long, and 1/8" deep).  The water would come in at the bottom manifold and flow 8' through these 'ribs' to the manifold at the top and out to the water heater.  Since these panels will not hold a lot of water, they won't weight that much, but I am still worried about the weight on the roof.  

One question:  since these panels are old, do I need to do anything with them other than flushing them with water?

Second question:  do you have a list of all of the components (pressure release valves, etc.) that you have bought from Home Depot or elsewhere? or blue prints? with catalog numbers?

Third question:  has anyone tried to make a business out of solar water heaters.  It seems like an easy sell especially if you can provide financing.

Thanks,

Steve

Copper ribbing? I sure that isn't cheap to make.

Being copper I wouldn't think there would be much maintenance. Maybe use a typical radiator flush chemical from a local auto supply store. That should ensure a thorough cleaning inside the ribs.

I personally don't place anything on my roof. In my younger days I was a roofer & repaired numerous leaks. Placing solar water or PV on a roof isn't my something I advocate. My panels are ground level.

My solar hot water system is an open system. I don't have any special valves & all purchased thru a local home improvement company.

I'm not aware of anyone from this forum that has opened a business selling solar panels. Hot air panels are easy, cheap to build, so they don't need financing. in my opinion, the only solar product getting any attention is solar pv. Most of that interest is via advertising & frankly a lot of it is hyped up. Once people see the price tag, even with tax incentives, the average home-owner turns away.

I've read where a company has some kind of solar pv lease program. I haven't looked at the details, but suspect the leasing price wouldn't be much different than what I pay for electricity already.

Thanks Jeff,

What components did you buy from the local store?

My water heater is in my attic so to avoid pumping costs, I would like to place them on the roof, close to the water heater.

Steppen,
   One problem with the attic is if you build a large water storage tank the floor will have to be able to support it.  This can be overcome but may cause additional expense to shore up the flooring and /or a smaller tank.

Every system is different and you will need to decide a design and what you need, then it depends on your location.  Many people have little access to common stores and even they are regional.  My local Menards has a couple of complete setups showing the main components of what you need.  Home Depot probably has the same.
Solar Web Page > Forums > Overall System Design > NABCEP certified Solar Heating installer and study and resource guide

I put a link in the above and this has many system designs that you can look at. here is the pdf http://www.nabcep.org/wp-content/uploads/2008/11/SH-Resource-Guide-v.1-Web-5-10-12.pdf

Once you determine a plan then you can try and figure out where and for how much those parts would be.  This project will not be cheap but can be cheaper if your able to do the work yourself.

Hi, Steppen,

Like Jeff and Dan, I would forget about the roof if you have got a suitable plot of ground space...
Perhaps U need to do a solar site survey (search for the term on Build It Solar).

OK, your HW heater is upstairs,but it is receiving its CW feed from ground level...

IMO, that is where you ought to be looking: a solar tank at ground level, with a coil in it: the CW from the town is routed through the coil, just like Scott's installation.  the tank is heated by a hot line from your collector(s).

It is this "solar preheated water" that then is fed upstairs to your HW heater: you are saving on energy costs by preheating with the sun.

You could also drive heating off the system, like Scott does.

Do some reading in the Hot Water section, you will pick up a lot of good ideas, and always come back with questions !

Good luck with the design,

G_H
