8 anti-3 strong solar heating boilers

 Due to the infiniteness, efficiency, benefits to environmental protection, and the economy, the proportion of solar thermal utilization globally is increasing. It is being widely used in households, hotels, hospitals, schools, factories, dormitories, venues,and other large-scale engineering systems. By being highly cost effective, with convenient installation, high efficiency, and excellent safety, Himin solar hot water systems are being widely used in various fields worldwide.

1.   Applications of Himin solar hot water system

In hotels, factories, dormitories, hospitals, schools and venues where the water consumption is proportionally higher, and the water usage is concentrated, the comfort requirement is paramount. Therefore, in these cases, centralized hot water system is installed.
1.1 Main advantages
A.        Easy installation, simple controls, and minimal maintenance;
B.        The frequency conversion pressured design is able to supply comfortable water on demand;
C.        Eight Preventative Measures: Anti-scald, anti-electrical leaks, anti-water leakage, anti-freezing, anti- potential danger from blockages and patching, anti-scaling, anti-excess lead, anti-overheating;
D.       Three strengths: Supplies hot water (no matter the weather), maintains consistent temperatures for hot water on demand and is controlled remotely by a large data platform;
E.        High efficiency, security, and highly cost effective.
1.2 Main Product: Composition of the system
1.2.1 Solar collector

Himin JPS collector is composed of high-efficiency vacuum tube. The exclusive using of the most advanced sputtered double cermet selective absorber coating makes the tube with absorptivity of 0.94 and emissivity of 0.04. It has water inside glass tube. The bracket goes together with the collector. The water circulation is inside the collector header, the tubes and the water storage tank, which is called direct system.
