Why Do You Use Solar Vacuum Tubes for Residential Water Heating?

Are you looking to purchase residential solar water heaters? You should look no further than solar vacuum tubes for solar water heating applications. These tubes are like a perfectly-built thermos. The air present in between both glass layers gets sucked out during the manufacturing process to form a vacuum.


There’s no air inside the vacuum layer; so there’s no way of heat transfer from a layer to another. It allows the solar vacuum tubes to absorb solar energy by up to 93% while losing around 7%. This makes vacuum tubes extremely efficient choice for residential solar water heaters.


Solar evacuated tube comprises of four specially coated layers of aluminum, copper and stainless steel. These layers help in absorption of solar energy and transferring to the centre of the vacuum tube.


How Do Vacuum Tube Residential Solar Water Heaters Work?


A solar evacuated tube collector works by heat energy transfer from the sun to a copper heat pipe present inside the vacuum tube. This copper heat pipe comprises of a small amount of distilled water. This vacuum is paramount for residential solar water heaters.


At sea level, water boils at 100 C. while minimizing the pressure, the boiling point of water changes. Water boils at the top of Mount Everest at only 35 C. It’s because of the less pressure. However, the water present inside the copper heat pipe is in a vacuum i.e. less pressure; boils at a much lower temperature of 30 C.


In fact, the boiling water creates steam vapor and it rises to the top of heat pipe into the expansion bulb. This bulb is inserted into a copper heat exchanger and steam loses its temperature and pressure and then back to water. It’s a continuous cycle that includes no moving parts. This means, the life of solar vacuum tube is over 20 years.


What Do You Invest in Solar Vacuum Tube Collectors?


Solar vacuum tube collectors offer so many benefits over other available flat plate collectors. Here are some of the best reasons discussed below:


Easy Installation Process –


You have to install the light weight aluminum frame first and the tubes. After that, plug in one at a time. You don’t need any crane or hoist for the installation of solar vacuum tubes residential solar water heaters.


Quality Performance –


Even if a vacuum tube breaks, the entire system still performs. This means, no fluid is lost from the system. Remember that, you can replace glass tubes at as low as $20 per each tube.


Year-Round Operation –


Though vacuum is present inside the solar evacuated tube collectors, there’s no heat loss. It means, they work effectively during cold winter temperatures whereas other types of collectors fail to work.


Final Consideration –


Latitude51 Solar specializes in providing perfectly-engineered residential solar water heaters at competitive costs. Our solar evacuated tubes remain at a perpendicular angle to the sun throughout the day.


Unlike flat plate collectors, our high performance vacuum tubes are always perpendicular to the sun. For more information about our products, please contact us as soon as possible at +1(800) 317-9054.
