Northern Lights Solar Water Heaters
                     Why Do Northern Liights Sollar Water Heaters Use SunRaiin Vacuum 
Tubes?
Are you looking to invest in the most advanced solar water heating system? If 
yes, then you should look no further than evacuated tube solar water 
heaters. They produce much higher temperature and deliver better 
performance during winter. Heating hot water during winter with 
solar vacuum tubes will outperform all other types of solar collectors 
available.
When it comes to buying a solar water heating kit, it’s important to make 
sure that the engine you choose is the most powerful one and made for long 
lasting performance. This is the reason why Northern Lights use SunRain’s 
patented 3-Hi solar vacuum tubes. There’s an absorbing coating present on 
the inner layer that determines the efficiency of the vacuum tubes. However, 
the coating material and method will enhance the life expectancy of solar 
vacuum tubes.
Most evacuated tubes utilize a hi-tech reactive sputtering procedure for inner 
tube coating. The aluminum and aluminum-nitrogen (AL-N/AI) coating are 
commonly used and are considered as primary absorbing coating. In fact, the 
SunRain solar vacuum tube technology uses the internationally patented film 
coating known as “3 Hi”.
Three systems are used in every solar vacuum tube to ensure heat 
absorption most effectively. This includes a AL-N/AI layer, an aluminum layer 
and a copper layer. The presence of additional layers ensures better heat 
conduction and stabilizes the coating that allow for a much longer lifespan of 
20 years or more. Once you use Northern Lights solar water heaters, you’ll 
find out the difference the power engine makes.

SunRain’s unique silver coat delivers two times heat transfer than most heat 
pipes available. It provides more heat energy transfer that results in more 
efficiency. As a premier name in the solar vacuum tube industry, SunRain has 
done so by providing superior quality products at the competitive prices. 
Moreover, SunRain Evacuated Tube Solar Collectors are the most affordable 
collectors available on the market as they provide the superior performance 
and best value.
