diy thermal storage tank 30 tubes at 30-40 degrees tilt should be desirable for 80-100 gallons in summer season for a family of 3-4.the additional 60 tubes should be established at a far better attitude 60-70 tiers for iciness use. The pleasant design might be to position them under an overhang to colour them inside the summer.My contemporary system consists of 90 evacuated tube machine with 80gal storage. I also have a 50 gal garage seperate for the diy thermal storage tank.

My issue is that inside the spring, summer season and fall, I should cowl 3/four of the tubes in order no longer to overheat. I admire your input and i have already started searching on the website you sent me. i'm able to problably warmth 10,000 gal of water to 180'f inside the summer time, but I just desire i can store it and preserve in warm all wintry weather. extra thoughts are welcomed. however I do not assume you will be capable of warmth 2000 gallons inside the wintry weather which is whilst you need the extra capability.
Assuming flat plate solar collector for sale 30K BTU in keeping with day in keeping with 30 tube array (8 hrs of sun ) = 90K BTU per day total. with your 50 gal. tank you may be capable of warmness your own home in Sept, Oct, March & April whilst temperatures are moderate.click here

What were your water temps this December for your solar tanks? how many rectangular ft are you heating, and the way nicely insulated is your home?
