Aurora Solar Flex SS - Stainless Steel Solar Piping

solar piping

Ever wonder what the most time consuming part of installing a solar thermal system is?  Hands down it is the solar piping!  Regular copper pipe requires high level of plumbing skills to carefully solder and run your copper.  Once soldered the entire system needs to be flushed to remove the poisonous flux acid and then the system needs to be pressure tested. This is the easy part!  Next the entire pipe system needs to be properly insulated.  Not with cheap polyurethane foam but high temp EPDM foam.  After this you then need to seal the insulation with either special tapes or tubing such that rain and sun won't damage the foam.   Think your done?   .... Wait you still need to run the sensor lines to and from the collector.   

Aurora Stainless Steel Solar Piping Line Sets are the only way to go.  With a life expectancy of over 120 years, quick install, no leaking joints; there is simply NO comparison to copper.  The 3/4" stainless steel solar piping comes with high temp 3/4" EPDM foam and a weather proof membrane jacket.  Also included on the solar line sets is a sensor wire all in one solar pipe.  SAVE TIME and MONEY.  Plug N' Save!  Solar Heating Solutions Made Simple!


Features of solar line sets:

  • Twin Flexible Stainless Steel Tubing  Solar Piping Line Sets 
  • UV Resistant protective coating on the solar piping
  • Built in sensor wire.
  • 3/4" Thick EPDM Insulation
  • High R Value Insulation surrounds the solar pipe
  • Rated to 350 C (660 F)


Save Money versus copper piping

  1. Buy 2 x 50ft rolls of copper (approx cost $200each) = $400
  2. Buy 50ft Cable = Approx $25
  3. Buy 100 ft of 3/4" EPDM Insulation (50ft supply and 50ft Return) = Approx $7.5 Per foot = $750
  4. Buy copper fittings, solder, flux, brushes, solder tank = $50
  5. Buy special plastic external protective tape to water proof the EPDM foam and protect it from damage = $50
Total so Far = $1275 

Save Time

  1. Run one roll of copper don't forget it is stiff and takes a good effort to run it where you want!
  2. Run the second roll of copper.
  3. Cut any 90 degree turns as soft copper has a very large turn radius, and solder on elbows
  4. Attach the EPDM Insulation (it is in 6ft lengths) to each pipe and secure with tie wraps.
  5. Stop to bandage all you knuckles up after you scrape your skin trying to wrap the insulation and tie wrap it under the floor or behind drywall.
  6. Run the wire / temperature sensor and secure it to the insulation.
    Remember all this pipe and insulation is likely behind dry wall, under floor boards etc - very time consuming!
  7. Cover the outside of the Insulation with UV resistant coating or tape to stop the sun ruining the insulation or the birds pecking at it!
  8. Solder on you end pieces
  9. Now because of solder you must flush the piping to remove any flux
  10. Test
