Accessories: intelligent controller, electric heater, magnesium bar, assistant tank etc. 

The vacuum tubes trap incident sun rays, and convert it to heat inside the inner tube. Water, now being heated its temperature rises, density changes, and hot water sections rise through the tube to the top of the tank, while cold water from the bottom of tank replaces it in the tube, to start the cycle again. This natural cycling of water driven by temperature difference keeps water hot when stored in an insulated tank.

Installation:

It is a non-pressurized tank, and has an opening to the ambient atmosphere. Solar water heater tank should always be filled with water to avoid damage caused by dry high temperature working conditions.

Before installation, please note:

1. Check the density, hardness and strength of roof structure to ensure safety of solar water heater.

2. The maximum snow load is: 1.2 times the weight of tank

The solar system must be installed in a non-shaded place. High buildings or trees may cause shade to solar water heater and reduce its performance.

For optimum performance, solar water heater should be installed facing towards the equator. For South Hemisphere solar water heater should be installed facing north, while for North Hemisphere should be facing south. Diverting for this north/south orientation is possible, given installation site conditions, and is best considered by your dealer’s appointed professional installers.

Low Pressure Solar Water Heater With Assistant Tank

Comparing with system without assistant tank, this model operates to feed water automatically. Using thermosiphon system depending on the different density between solar hot water heater and cold water, a water flowing cycle is created in the tubes. Hot water flows automatically upwards while the cold water flows down. The water in the storage tank will be heated from this natural circulation.
