DR-SWH01 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 amount of solar radiation available. On a good sunny day with 6 to 7 hours of sunlight,the vacuum tubes will collect enough solar energy to heat 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 in low temperatures. With vacuum tube technology,the reliability of the system increases,since the temperature inside the glass tube is independent of the surrounding temperature.
