Compactsolar water heater is a kind of solarwater heating system that solar collectorand storage are connected together withthe cylinder storage on the top andcollector panel on the bottom. Thereis no need of pump to push the fluidand no need of pipeline between thecollector and storage. It is a simpleand safe solution to get heat powerfrom the sun.
Description:
The compact solar water heatersrelies on the natural circulation ofwater between the collector and thetank or heat exchanger. As water inthe vacuum tubes is heated it risesnaturally into the tank, while coolerwater in the tank flows down to thebottom of the vacuum tubes, causingcirculation throughout the system.
CompactSolar Water Heater (SJK series) :
Compact Solar Water Heater (SJK series)relies on density of the water, coldwater down, hot water up, a cosmicalphysics. To circulate water throughthe collectors and the tank. When waterin the collectors is heated up, it becomeslighter and naturally rises into thetank. Meanwhile, cooler water in thetank flows down to the collectors.
In this type of installation, the tankmust be together with the collectors.These systems are reliable and relativelyinexpensive but be careful with theinstallation, because the water tankis much heavier than that you thought.
Compact Solar Water Heater (SJK series)can work without circulating pump. whenthe aid electric breaks down, it can’taffect the working of the whole system.This makes the systems generally morereliable, easier to maintain, and hasa long living life. This type much cheaperthan the others, but are also generallyless efficient due to slower water flowrates through the system.
Features:
Cheap and reliable solution, Simplestructure, Easy installation
High efficiency
Withstands water pressure no morethan 0.1MPa
Operated without any power supplying
Electric heater can be used 1500Wor 3000W
Hot water can be used directly, orcan be used as a pre-heat
