In addition to more insulation, you might want to check that your are not getting reverse thermosyphoning at night. This would be circulation of water through...
I do not know what kind of material you have access to, but just insulating better would be the answer. if your tank gets hot in the day time you setup seems...
Matthew, I am using same system like below URL. ( http://www.byexample.com/projects/early/flat_panel_collector ) My tank is old Steel heater, it doesn't have...
Could you try to describe how your system works in a bit more detail. Maybe photos/diagram of actual system, or of a similiar one online. it is hard to say...
I am using a simple system which provides me hot water, the area where i am live has quite high temperature during day and my system provides best results. But...
Why not put a slight incline on each horizontal run of the serpentine tube to allow the fluid to completely drain from each segment? In Christ Alone! \o/ Paul...

It seems that most people use a snap switch in air collectors, but what do you use in a hydronic collector? Somehow it seems that it would have to work...

Pierre, I see you use metric units. This list is based in the US and most members here use imperial units and are less likly to do the conversions needed to...
Hi Pierre, This video will give you a good overview of the hot air collector options: http://www.youtube.com/watch?v=gBLQ2ZUeP7w And this one shows just how...

... I'm new here and don't know the lingo. What is a screen absorber? What is a 3CFM? The fans blow into ducts which are no bigger than 362 mm × 235 mm on the...
Hi Pierre, For an air collector, a screen absorber is a great choice in that it is easy to work with, inexpensive and performs superior to other options. For...
Ged, I take your point - but we get enough sun for the rest of the year to make it worthwile (it'll obviously point south and direct heat into north facing...
Hi From the diagram, the collector looks like it thermosyhons without a pump. So, water in the collector heats up, gets less dense, rises up out of the...
The serpentine drainback system looks good. I repeated a similar experiment that Gary ran and came up with the same results. John...

Thanks Ryan, Is this the better way to make solar water heater. I found this as cheaper way, as per Scott video i can use CPVC, but how much it makes different...
I'm going to go ahead with the two screen collectors, they're not too much trouble to put together. If these prove to be reasonably effective I will follow on...
The temperatures are only relative and usually only vary by a degree or two depending on the tank size. It's an example of thermal stratification, the hot...
