| Apricus (SolarLink) Evacuated Tube Technology |
 |
|
|
Apricus evacuated tubes comprise of two essential parts, a glass solar tube and a heat pipe.
in a Nutshell...
The evacuated tube contains a fluid which will evaporate when heated - this vapour then rises up inside the tube until it reaches a membrame. The heat inside the vapour passes through this membrame into the cold water just beyond it. This is a very basic description of what actually happens, so if you would like to read a more detailed explanation on the individual parts, please follow the links below.

Closed vs. Open Systems
|
Our evacuated tube solar panels come in two different formats - one has been designed to work inside a closed system whereas the other operates within an open system. These two terms refer to the way that the water that has been heated up by the solar system is used inside the heating system.
An Open SolarLink System heats your hot water directly. I.E., cold water is channelled into the roof, heated directly by your solar energy, brought down through the remainder of your heating system and finally out through say, your shower or taps. As such, fresh water is continuously brought into an open system, and hot water leaves it directly.
A Closed SolarLink System heats your hot water indirectly. I.E., water is circulated up to your roof and heated by solar energy in the same way it would in an open system but with one crucial difference - the hot water that circulates inside a closed system never leaves it. Its sole function is to indirectly heat fresh water through a coil inside a hot water cylinder.

So which one do I choose? An open or a closed system?
A. Well it depends, what is it that you are looking to do with your heating system?
SolarLink operates as a component within a larger heating system - the choice between an open and a closed evacuated tube set should take this system into account. To do so, consider the following:- What will your hot water be used for?
- How much hot water will be required? Is there a time-frame on this requirement? (i.e. do you need large quantities immediately?)
- Is there a heating system in place already? If so, what kind?
- What kind of components tie into this heating system? Will the hot water requirements of these components be met by SolarLink or an independent heating unit?
- What kind of water pressure, temperature etc. can the current system handle? (If there is one already)
Choosing between an open and a closed set of evacuated tubes can profoundly affect the design, efficiency and function of your overal heating system - if you would like to get some feedback from us on this decision, please contact us directly - it's what we do.
