What is Twin Flexible Stainless Solar Hose with Cable is and What does it Include?

solar hoseA Flexible Solar Stainless Steel Hose is the hydronic link between Outdoor Solar Collector, Solar Storage Tank with immersed Coil and Pumping Station (as shown in the picture below). it's represented by the bold hatched lines in the schematic below. Delivery includes High quality flexible stainless Dual Twin (Supply & Return) steel pipe with Solar Collector temperature sensor's cable (Sensor is Excluded. The cable is only included), high temperature EPDM insulation pipe, up to 175C, strong seamless jacketing protection (Non PVC including) good UV resistance and anti-aging performance, excellent performance for both indoor and outdoor installations.

Joinability and Ease of Fabrication: 

Since Stainless Steel solar pipes are flexible, they are much easier to work with. All the installer has to do is to open the box, uncoil the piping and then start snacking it through the building. Pre insulated solar hose only require 1 step to finish the Solar Water Heater Pipe Installation. Unlike Copper Coils, changing directions with Stainless Pipes does not required any Cutting, welding, brazing or special tools (such as pipe Bender, etc...). The system is light weight and space saving, which is easy to handle, even in confined spaces. Supply and return pipes are marked clearly and can be easily distinguished. Smart Design- Break Point allows installer to separate twin pipes into individual pipes without damaging the jacketing protection. For More information on how to manipulate Solar Flexible Stainless Steel pipes, refer to our technical Blog: Step by Step Solar Hose Installation.

Friction Loss:

This product has a great place in systems whose pump flow rates are small if you used the 3/4 inch sized stainless steel product. On the one hand, the 1/2 inch SS Pipe has about four to five time the head loss of smooth copper pipe of the same size. On the other hand SS Pipe has less short radius elbows. That's why we don't recommend using the 1/2 Inch pipe size for applications having more than one Vacuum Tube Collector. For more information please refer to our Flexible Solar Pipes Friction Loss Chart
