Khanak Solar system offers solar water heating system based on evacuated glass tube system. It is an effective and excellent solution to reduce costly energy bills during heating of water. A solar water heating solution works alongside your current heating system to use the sun’s energy to reduce your consumption of oil, propane, CNG gas or other fossil fuels. Traditionally used with solar evacuated tube collectors, these systems work to provide free, solar heating for your home throughout your entire heating system.
Working of system
Evacuated tube collectors are the most efficient collectors available. Each evacuated tube is similar to a thermos in principle. A glass or metal tube containing the water or heat transfer fluid is surrounded by a larger glass tube. The space between them is a vacuum, so very little heat is lost from the fluid.
These collectors can even work well in overcast conditions and operate in temperatures as low as -40°F. Individual tubes are replaced as needed. Evacuated tube collectors can cost twice as much per square foot as flat plate collectors.
