Why Should You Choose An Evacuated Tube Solar Hot Water System?

Evacuated tube hot water systems make use of the latest technology for maximising the water heater systems' efficiency. Evacuated tube solar is composed of heat pipes that are surrounded by glass tubes, an outer tube and an inner tube. The space existing between the two glass tubes is evacuated for creating a vacuum for heat retention as collected from the sun and reduce heat loss. Each evacuated tube's top is connected to the heat transferring device termed as the manifold.  A water piper connected to the insulated water storage tank is there within the manifold.  

 

How Do The Evacuated Tube Solar Water Heater Systems Work?

With the liquid inside the heat pipe being heated up with the energy gathered from the sun, it gets evaporated into a hot vapour rising to the pipe's top. Then, the heat from the vapour is transferred to the manifold at the pipe's top. As the vapour cools down, it gets reverted back to a liquid and returns to the pipe's bottom for being heated. Coldwater gets pumped through the pipe in the manifold, where the heat gets transferred to the water. With the water being heated, the water returns to the storage tank.

The Conveniences of the Evacuated  Tube Solar Hot Water Systems

Chiefly, the advantages make it clear why you can trust the evacuated tube solar hot water systems.

i. Efficiency –  When compared to the flat panel systems, the evacuated tube hot water systems are more efficient at transferring heat. Rather, the evacuated tube systems are 163% more efficient to transfer heat. The evacuated tube systems enable heating water to a temperature of over 90ºC, while the flat plate systems just heat water to 60ºC.

Moreover, the evacuated tube system's rounded shape allows water to be heated from early morning until late afternoon. The flat panel systems conversely work best when the sun is perpendicular to the solar collector.

ii. Repairs Are Cheaper – The evacuated tube systems can be repaired by the professionals providing hot water repairs, and at much cheap rates.  Each tube in an evacuated tube system can be removed individually and replaced if they are found to be damaged. Thus, the cost of repairs is reduced. But when the repairs should be done, be sure to hire specialists from the best hot water system repair company in Perth.

On the other hand, the flat panel systems involve expensive repairs when they are damaged, since they are lacking the evacuated tube system’s modular design.

iv. Functions in Most Weather Conditions

The evacuated tube hot water systems function in colder weather by heating water, thus outperforming the flat panel systems.  Although each system makes use of the heat in the air for heating the water yet the evacuated hot water systems work in the extreme cold temperatures compared to the flat panel counterparts, thereby providing hot water throughout the year.

So, when the evacuated tube solar water is compared to the traditional flat plate collectors, they are advantageous over them –

 a. Enhanced ability at capturing sunlight since more of their surface areas are exposed to the sun.

 b. Efficient by 163% in heat transfers as having been demonstrated in the Australian conditions.       

 c. Proper to use in subzero temperatures.

 d. Durability is greater, still if a tube breaks then it can be easily replaced and  afforded.

 e. Performs with excellence in overcast conditions.

 f. Needs a smaller roof area.

 g. Less corrosion prone.

When you are converting to solar hot water from electric hot water for reducing your electricity bills by 80%, update yourself with the advancement in solar technology. This advancement is the evacuated tube thermal collector. Vacuum is present in each tube in between two glass layers insulating against heat loss. The evacuated tube collectors have gained popularity owing to reduced manufacturing costs, exceptional performances all year round, and for sure an attractive appearance.
