CE-approved Solar Water Heater
Working Principle of Non Pressurized Solar Water Heater:
1.Convective movement of water starts when it is heated in the loop;
2.Then, it expands and becomes less dense, and thus more buoyant than the cooler water in the loop;
3.Thus,convection moves heated water upwards in the system as it is concurrently replaced by cooler water droping downwards due to gravity;
4.In this way,the water in the storage tank becomes hoter and hoter;
5.The water flows easily because a good thermosiphon should have very little hydraulic resistance.
Features of Non Pressurized Solar Water Heater:
1. High Efficient:
Excellent selective absorbent coating and perfect combination with high vacuum heat preservation.
2. All Weather Hot Water Supply: Backed up with auxiliary electrical heating device,supplying enough hot water in bad weather days.
3. Easy Operation: Adding water automatically, you can take it easy and enjoy good time.
4. Energy Saving and Environment Friendly:Taking advange of solar energy,free of charge and no pollution
5. Stable and reliable performance and well wind resistance.
6. Dual-purpose brackets for both flat and inclined roof
7. Multifunction: Bathing, washing, domestic heating etc.
Warranty:
1.3 years'responsibility for free repairing or exchanging due to original
2.15 years'quality guarantee for the vacuum tube, and offering 0.8% vacuum tube free for exchanging in case several shattered ones during transportation.
