Evacuated Tube Solar Hot Water Systems
Evacuated Tube Solar Hot Water Systems
Evacuated tube solar hot water systems are fast becoming the preferred solar hot water system installed on Australian homes.
These lightweight and low-maintenance units use clever technology to maximise efficiency and keep your water warmer for longer.
Unlike flat panels, evacuated tube solar hot water systems use a series of glass tubes which sit side by side on the roof of your property. Inside the tubes are vacuums as well as copper pipes which stretch from one end to the other. As sunlight hits the dark absorber coating inside the tube, they become incredibly hot. This heat is transferred into an insulated storage area where water continually flows through and warms up.
The warmed water is then pushed down into the storage tank where it remains until you’re ready to use it.
So why choose an evacuated tube solar hot water system?
Evacuated tubes are not only popular in Australia, but are sold in their millions around the world. Compared with flat panels, evacuated tubes are able to absorb more heat from the sun due to their unique shape and positioning. They do not require the sun beaming down on them directly for maximum output, meaning more efficiency and less reliance on your gas or electric back-up.
What’s more, evacuated tube solar hot water systems are incredibly resistant to frost and they’re also tough and long-lasting. In the rare event that a tube does become damaged, they’re easily replaced at a small cost.
Indeed, evacuated tube solar hot water systems are the next step in technology towards total independence from grid-derived water heating.
