30 Tube Duda Solar Water Heater Collector 37° Frame Evacuated Vacuum Tubes SRCC Certified Hot

I have been using this collector for 6 months now and there is a tremendous amount of heat collected from the sun. I may purchase another panel to help heat the whole house. I am heating the whole house with it now and without a storage tank and just a heat exchanger, it puts heat into the basement floor under slab tubing and main floor radiators, but I cannot collect 100% of the heat it puts out during the day. I will be installing a storage tank so I can make the most of the day time sun. Great item.

Once installed and delivered unbroken it produces great hot water to heat my home. It works great!The big "but" is that many packages came broken and glass all over. Needed leather gloves. Difficult to dispose of. They need better and safer packaging.
