On top of that the round tubes are excellent at self cleaning when it rains also helping keep your system as efficient as possible. This ultimately means that you will use less of your electric or gas booster if you live in those cllimates. They get more heat from the sun for a longer period of the day and their improved performance is most noticeable through the colder seasons and colder climates.
Well the main reason is that good ones will give you more hot water in colder parts of Australia. So why do people choose to pay more for an evacuated tube system? The are also more fragile, which is pretty obvious just by looking at them! In contrast a flat plate collector is at its most efficient only when the sun is directly above the panel.Īs you can imagine, these panels are quite tricky to manufacture, so they are typically more expensive than a similar quality flat plate collector. And the fact that the tubes are round, not flat, means that they can efficiently collect heat no matter where in the sky the sun is.
The name comes from the fact that a vacuum (which is an excellent insulator) is created during manufacturing between the outer and inner glass tubes, this makes for a very efficient solar heater. Basically each tube is like a little greenhouse that traps sunlight inside the glass tube which is used to heat either the water directly, or a special heat transfer fluid that transfers the heat to the water. There are loads of different designs, but the basic principle is the same for all designs. Whilst flat plate collectors are all pretty similar in design, construction and performance, evacuated glass tubes can vary widely in their design and performance.Įvacuated Tube Collectors collect the heat through a number of annealed glass tubes that each have their own heat-absorbing plate inside.
