Characteristics:
DR-SWH*1 uses all-glass Vacuum Tubes as heat absorbing element. It
has excellent properties of high absorption and low emittance rate.
The output of a solar water heater will depend on the solar
radiation available. On a good sunny day with 6 to 7 hours
sunlight, the vacuum tubes will collect enough solar energy to heat
the water up to 60℃ and the water temperature can rise very
high and you may spot steam coming from the vent. Rainy days: these tubes perform
very well in overcast conditions and low temperatures. With vacuum
tube technology, the reliability of the system increases, since the
temperature inside the tube is independent of the surrounding
temperature.
