Flat Plate Thermal Water Heating Panel
Flat plate collectors are cheaper than evacuated tube collectors, and they also have the advantage that you can just pump water through them when you want hot water and let the system drain down when not more hot water is needed. This is good for cold winters where the system could automatically drain down from the panel at night to prevent freezing and then just pump water through when needed to heat during the day.
