compact solar water heater

Product Description

Water heater

A. Working principle

Hot water rises and cold water sinks. Warm water rises when the phenomenon known as natural convection happens, to circulate water through the collectors and to the tank. The tank must be located above the collector. As water in the collector is heated, it becomes lighter and naturally rises into the tank above(that's the reason why tanks are always above the collector/tube). Meanwhile, cooler water in the tank flows downwards into the collector, thus causes circulation throughout the system. This system is reliable and relatively inexpensive.

B. Advantages
1) He most reliable, cost saving, efficient and the most common water heating Solution worldwide with simple structure, easy installation and few maintenance Operations;
2) High efficiency with daily average efficiency higher than 50%, it provides hot Water after only a few hours of solar radiation. This system is ideal to assure the Hot water needs of one family;
3) Can be operated completely automatic if connect with intelligent controller;
4) Operation without any power supply as back-up support, do not need pumps And other controls, reduce your initial invest cost to the greatest extent;
5) Could be installed with parallel or series connections for large scale project;
6) If in rainy or cloudy days, you can heat the water through the auxiliary electric Booster to heat your water;
7) Corrosion resistant inner tank, superior heat preservation ensured by one-off
Molding polyurethane foam with thickness 50mm-65mm.
8) The vacuum tube solar water heater is much more efficiency than the flat plate Ones.
