These are the pics of our installation on the Central Presbyterian Church across the Capital building in down town
Atlanta. Can you all see the capital dome in the back ground?

Just wondering what drove the discussion on evacuated tube .vs. flat plate collector panels here. Higher cost for evacuated tube not doubt but also higher efficiency. Would like to hear thoughts on that.

Randy, 1. Actually the cost was almost same as flat plate. 2. The differences are higher yield both during summer and more so during winter times. 3. If one tube breaks, the replacement cost is about $30.00 or less. If a flat panel breaks, it would be more like 300 to 400 dollars. (you will have to pay a plumber to take it all apart and put it back together, 4. It was very easy to carry these tubes to the roof (the frame was assembled first on the roof and tubes were installed following the above). Imagine carrying a 250 lbs flat panel to the roof... The church uses almost 800 gallons of hot water per day. The year after this was installed we got a phone call from the maintanance person that they observed incoming water temp of 140*F to the heat exchanger -- this is very common if installed properly. They have a huge storage tank. We have radiant floor heating assisted y the evacuated tube collectors in our home. Our average heating bill for a 6970 sq.ft home is about $75.00 each month. In case you are interested, we have 20 evacuated tube collectors which are on clearance sale for the year end if you are interested..7702860578.
