solar water heater evacuated tube collectors
Commercial or Residential ApplicationsEvacuated tube solar collectors are suitable for most all climates. Evacuated tube collectors
are about 25% or 30% more efficient than
flat-plate collectors. Designed for areas where flat-plate
collectors do not perform well, such as cold climates,
evacuated tubes may also be a better solution for larger homes or
commercial applications, such as hotels, motels, laundries, restaurants
and car wash.
Evacuated tubes collectors come in modules for easy and flexible installation. We can help
you to select the right collector for your application. For
a regular-size home, a household of 3 to 5 people, or a small commercial
facility, we have pre-packaged kits to
help you saving time and money. Contact us for pricing
Evacuated Tubes Solar Collectors Specification
Evacuated tubes are made of borosilicate glass, 1.0 MPa resistant.
The supporting structure is made of aluminum. We carry 4
sizes of evacuated tube collectors, from 10 to 30 tubes.
The number of evacuated tubes will depend on the application.
For most residential applications, our pre-packaged kits will
perform well.
For larger homes and commercial applications, site analysis and
engineering may be required. Learn on the process of
sizing and selecting
evacuated tube solar collectors and how to
place your order. You may also
consider flat-plate
solar collectors for your application. Play with our
