Are evacuated tube solar collectors efficient?

High efficiency: Evacuated tube solar collectors are highly efficient due to their vacuum-sealed design, which minimizes heat loss. This enables them to convert a higher percentage of sunlight into heat energy compared to other solar collectors, like flat-plate collectors.

Can multiple etc-30 collectors be connected to a larger solar thermal array?

For commercial projects that demand a lot more hot water such as such as hotels, dormitories and car washes, multiple ETC-30 collectors can be connected to form a larger solar thermal array. Choose the correct sized collector by clicking here.

What are evacuated tube collectors used for?

Our evacuated tube collectors are great for a variety of residential solar heating applications, including: traditional hot water systems, radiant/space heating, and pool/spa heating.

What is the difference between evacuated tube collectors & evacuated tubes?

While both types of collectors capture the suns energy and convert it to hot water each have there own advantages. Evacuated Tube Collectors are best used in northern climates where freezing can occur and can be utilized in areas where temperatures drop down to -60°F. Evacuated Tubes are are extremely efficient by virtue of the Tubes themselves.

Can evacuated tubes melt snow?

For Evacuated tubes however, there is very little you can do to melt the snow. If your collectors are sitting at a tilt off from the roof pitch, you should be okay because the snow will pass between the tubes onto the roof. But for flush mount EVT systems, snow can and will build up.

Is there water in the evacuated tubes?

There is no water in the evacuated tubes. This allows for excellent winter performance by transferring the heat into the tank with the copper heat pipe without any freeze concern. Also, if one tube is broken, the system continues to work without the tank draining.
